The Galaxy Include File package consists of four files (<I>Galaxy.inc,
|
|
Galaxy.bg, Galaxy.obj</I> and <I>Galaxy.sf</I>) which work separately and together,
|
|
depending on the desired effect. All four files should be copied to
|
|
one of the directories (folders) in your POV-Ray library path. Normally
|
|
this is the <I>INCLUDE</I> sub-directory of the directory where you installed
|
|
POV-Ray, so if you installed POV-Ray in <I>C:\POVRAY</I> you should copy the files
|
|
to <I>C:\POVRAY\INCLUDE</I>. On a Windows 95 system, this is probably something
|
|
like:
|
|
|
|
<P><I>C:\Program Files\POV-Ray for Windows\Include</I>
|
|
|
|
<P>On UNIX and similar systems, where filenames are case-sensitive, you may
|
|
have to rename the four include files so that the filenames are all uppercase.
|
|
This will enable you to render the sample files without modification.
|
|
|

The Galaxy Include File package allows you to create a variety of outer-
|
|
space scenes which can be used on their own or as backgrounds to other
|
|
scenes and animations. In addition to spiral galaxies, the Galaxy Include
|
|
File package can also create starfields, star clusters, nebulae, comets,
|
|
and meteor showers. You can easily create a galaxy scene containing a
|
|
selection of these elements by adding the following lines to a POV-Ray
|
|
scene file:
|
|
|
|
<P><CODE>#declare galaxy_seed = 123456789;
|
|
<BR>#include "GALAXY.INC"</CODE>
|
|
|
|
<P>You can choose any positive or negative integer you like for the
|
|
<A HREF="#galaxy_seed">galaxy_seed</A> value. When you render this scene, the Galaxy Include File
|
|
will select random options, and then use <I>Galaxy.bg, Galaxy.obj,</I> and
|
|
<I>Galaxy.sf</I> to create the galaxy scene. In addition to changing the seed
|
|
number, you can use a variety of options to modify the galaxy scene.
|
|
To use any of these options just add the following line to your scene file,
|
|
<I>before</I> including <I>Galaxy.inc</I>:
|
|
|
|
<P><CODE>#declare </CODE><I>[variable-name]</I><CODE> = </CODE><I>[value]</I>
|
|
|
|
<P>substituting the desired variable name and value where appropriate.
|
|
Note that <I>Galaxy.inc</I> (or any of the <I>Galaxy.*</I> files) should <B>never</B> be
|
|
included at the start of a scene (like <I>colors.inc</I> or <I>textures.inc</I>).
|
|
They should only be included after declaring the desired galaxy options.
|
|
|
|
<P>As well as creating random galaxy scenes using <I>Galaxy.inc</I>, you can use
|
|
<I>Galaxy.bg, Galaxy.obj</I>, and/or <I>Galaxy.sf</I> separately to build custom galaxy
|
|
scenes piece by piece. You can include any of the four <I>Galaxy.*</I> files as
|
|
many times as you want in a single POV-Ray scene, declaring separate options
|
|
for each <I>Galaxy.*</I> inclusion. Note that you don't have to redeclare any
|
|
options that are common to any or all of the <I>Galaxy.*</I> files, eg:
|
|
|
|
<P><CODE>// COMMON GALAXY OPTIONS
|
|
<BR>#declare galaxy_colour1 = < 1.3, 1.2, .8> ;
|
|
<BR>#declare galaxy_colour2 = < 1, .5, .3 > ;
|
|
<BR>#declare galaxy_rotate = < 90, 180, 0> ;
|
|
|
|
<P>// GALAXY BACKGROUND
|
|
<BR>#declare galaxy_bgstars = 4;
|
|
<BR>#declare galaxy_bgnebula = off;
|
|
<BR>#declare galaxy_nebula_sphere = 5;
|
|
<BR>#include "GALAXY.BG"
|
|
|
|
<P>// GALAXY OBJECTS
|
|
<BR>#declare galaxy_object_name = "Nebula3"
|
|
<BR>#declare galaxy_cluster_name = "Star4"
|
|
<BR>#include "GALAXY.OBJ"
|
|
|
|
<BR>#declare galaxy_object_name = "Comet2"
|
|
<BR>#declare galaxy_cluster_name = ""
|
|
<BR>#include "GALAXY.OBJ"</CODE>
|
|
|
|
<P>In the above example the same colours and rotation are applied to each
|
|
element of the galaxy scene, without having to redeclare them each time
|
|
you include one of the <I>Galaxy.*</I> files.

As mentioned above, the four different files of the Galaxy Include File
|
|
package can be used in a variety of ways, depending on how you wish to
|
|
create your galaxy scene. The files are:
|
|
|
|
<P>The Galaxy Backgrounds File (<I>GALAXY.BG</I>): this include file is used to
|
|
create a selection of starfield and nebula pigments (including a Milky Way
|
|
pigment), which can either be mapped directly to the sky_sphere, or to an
|
|
actual sphere object. Although <I>Galaxy.bg</I> allows you to create backgrounds
|
|
quite easily, the file gives you little control over the exact shape of the
|
|
nebulae, and the starfields are not suitable for anti-aliasing or
|
|
animations in which the camera is moved or altered in some way.
|
|
|
|
<P>The Galaxy Starfield File (<I>GALAXY.SF</I>): this include file is used to create
|
|
starfields consisting of actual objects, rather than textures. Because of
|
|
this, the starfields can be anti-aliased and animated very well, and
|
|
improved programming means that the parsing takes about one fifth of the
|
|
time needed for previous versions of the Starfield Include File. <I>Galaxy.sf</I>
|
|
can create three different types of stars, and can be used in conjunction
|
|
with <I>Galaxy.bg</I> to create stars larger than one pixel in size.
|
|
|
|
<P>The Galaxy Objects File (<I>GALAXY.OBJ</I>): this include file is used to create
|
|
and position a selection of outer-space objects, including four different
|
|
feature stars, six different nebulae, five different galaxies, three
|
|
different comets, and two different meteors. The objects can be positioned
|
|
individually, or in random clusters (eg. star clusters or meteor showers).
|
|
|
|
<P>The Galaxy Include File (<I>GALAXY.INC</I>): this include file uses the above three
|
|
files to create random galaxy scenes. <I>Galaxy.inc</I> selects random options for
|
|
the other files, including colours, object types, scaling, rotation, etc.,
|
|
and can automatically include the other files into your POV-Ray scene, making
|
|
it quick and easy to use the Galaxy Include File package without having to
|
|
declare separate options for each of the <I>Galaxy.*</I> files.

Galaxy.obj</I>, and <I>Galaxy.sf</I>.

<P><A NAME="galaxy_seed"></A>
|
|
<B>galaxy_seed</B>
|
|
<HR>
|
|
This is the random number seed used for all random aspects of the Galaxy
|
|
Include File package. Changing this number can result in vastly different
|
|
galaxy scenes, and any positive or negative integer accepted by POV-Ray can
|
|
be used. The default <I>galaxy_seed</I> value is 0. Each time you include
|
|
<I>Galaxy.inc</I>, a new <I>galaxy_seed</I> value is chosen at random. To find out the
|
|
new value, see <A HREF="#debug_options">debug_options</A>.
|
|
|
|
<P><A NAME="galaxy_colour"></A>
|
|
<B>galaxy_colour</B>
|
|
<HR>
|
|
Use this option to change the overall colour of the galaxy scene. The
|
|
exact result of changing this option depends on the current colour of
|
|
the galaxy scene, eg. if the current galaxy scene is predominantly green,
|
|
setting <I>galaxy_colour</I> to < 1.5, 0.1, 1> will increase the amount of red
|
|
in the scene, decrease the amount of green, and leave the blue unaltered,
|
|
resulting in a purple coloured galaxy.
|
|
<BR>The default <I>galaxy_colour</I> value is < 1, 1, 1> (which has no effect).
|
|
|
|
<P><A NAME="galaxy_colouration"></A>
|
|
<B>galaxy_colouration</B>
|
|
<HR>
|
|
Use this option to increase of decrease the amount of colour in the galaxy
|
|
scene. Good values range from 0 (little or no colour) to 1 or larger (very
|
|
saturated colour). Setting this option to a low value means that the
|
|
<A HREF="#galaxy_colour">galaxy_colour</A> option has more of an effect.
|
|
<BR>The default <I>galaxy_colouration</I> value is 0.5
|
|
|
|
<P><A NAME="galaxy_colour_turb"></A>
|
|
<B>galaxy_colour_turb</B>
|
|
<HR>
|
|
Use this option to alter the amount of colour variation between different
|
|
elements of the galaxy scene. Setting this option to 0 results in a
|
|
monochromatic galaxy scene, while larger values give greater colour
|
|
variation. The default <I>galaxy_colour_turb</I> value is 0.2
|
|
|
|
<P><A NAME="galaxy_intensity"></A>
|
|
<B>galaxy_intensity</B>
|
|
<HR>
|
|
Use this option to increase or decrease the overall visibility of the
|
|
galaxy scene. Good values usually lie somewhere between 0 (completely
|
|
transparent) and 5 (very opaque).
|
|
<BR>The default <I>galaxy_intensity</I> value is 1
|
|
|
|
<P><A NAME="galaxy_rotate"></A>
|
|
<B>galaxy_rotate</B>
|
|
<HR>
|
|
This option is a vector that is used to rotate the galaxy scene as a whole.
|
|
It can be useful when you want to create the illusion of movement in an
|
|
animation, without having to transform the camera and all the other objects
|
|
in a scene. The default <I>galaxy_rotate</I> value is < 0, 0, 0>
|
|
|
|
<P><A NAME="galaxy_distance"></A>
|
|
<B>galaxy_distance</B>
|
|
<HR>
|
|
All the objects in a galaxy scene are arranged around a giant sphere,
|
|
usually surrounding the camera. You can use this option to set the size of
|
|
this sphere. The default value is 10000, which should be sufficient for
|
|
most scenes and animations. If the rest of the objects in your scene are
|
|
this size or larger, you may need to increase this value. However, values
|
|
that are too large may result in disappearing objects, or cause POV-Ray to
|
|
crash when rendering the scene.
|
|
|
|
<P><A NAME="galaxy_origin"></A>
|
|
<B>galaxy_origin</B>
|
|
<HR>
|
|
As mentioned above, the objects in a galaxy scene are arranged around a
|
|
giant sphere. By default this sphere is centred around < 0, 0, 0>, but
|
|
you can use this option to change this value.
|
|
|
|
<P><A NAME="galaxy_bg"></A>
|
|
<B>galaxy_bg</B>
|
|
<HR>
|
|
Use this option to disable the elements of the galaxy scene created by the
|
|
Galaxy Backgrounds File (<I>Galaxy.bg</I>). Setting this option to false (or off)
|
|
removes the background stars, background nebulae, and nebula sphere from
|
|
the galaxy scene. To remove these elements individually, see <A HREF="#BG Options">Background File Options</A>.
|
|
|
|
<P><A NAME="galaxy_objects"></A>
|
|
<B>galaxy_objects</B>
|
|
<HR>
|
|
Use this option to disable the elements of the galaxy scene created by the
|
|
Galaxy Objects File (<I>Galaxy.obj</I>). Setting this option to false (or off)
|
|
removes any feature nebulae, stars, comets, star clusters, or meteor
|
|
showers from the galaxy scene. Note that this option is always set to
|
|
false after including <I>Galaxy.inc</I>; if you wish to include <I>Galaxy.inc</I> a
|
|
second time (or third, fourth, etc.) and have it automatically create galaxy
|
|
objects, you must manually set <I>galaxy_objects</I> to true before including
|
|
<I>Galaxy.inc</I>.
|
|
|
|
<P><A NAME="galaxy_starfield"></A>
|
|
<B>galaxy_starfield</B>
|
|
<HR>
|
|
Use this option to remove the starfield objects in a galaxy scene created by
|
|
the Galaxy Starfield File (<I>Galaxy.sf</I>). Note that this option is always
|
|
set to false after including <I>Galaxy.inc</I>; if you wish <I>Galaxy.inc</I> to
|
|
automatically create another starfield, you must manually set
|
|
<I>galaxy_starfield</I> to true before including <I>Galaxy.inc</I>.
|
|
|
|
<P><A NAME="options_only"></A>
|
|
<B>options_only</B>
|
|
<HR>
|
|
Setting this option to true will cause <I>Galaxy.inc</I> to declare all the options
|
|
it uses for <I>Galaxy.bg, Galaxy.obj</I>, and <I>Galaxy.sf</I>, but these three files will
|
|
not be automatically included. You can use this to then alter selected
|
|
galaxy options, before including some or all of the remaining <I>Galaxy.*</I> files,
|
|
eg. say you have discovered you like the galaxy produced by using 7362512
|
|
as the <A HREF="#galaxy_seed">galaxy_seed</A> value, but you want to change the galaxy object used:
|
|
|
|
<P><CODE>#declare galaxy_seed = 7362512;

<BR>#declare galaxy_object = "Galaxy2"
|
|
<BR>#include "GALAXY.OBJ"
|
|
<BR>#include "GALAXY.BG"
|
|
<BR>#include "GALAXY.SF"</CODE>
|
|
|
|
<P>Note that setting <I>options_only</I> to true is the same as setting <A HREF="#galaxy_bg">galaxy_bg</A>,
|
|
<A HREF="#galaxy_objects">galaxy_objects</A>, and <A HREF="#galaxy_starfield">galaxy_starfield</A> to false.
|
|
|
|
<P><A NAME="debug_options"></A>
|
|
<B>debug_options</B>
|
|
<HR>
|
|
Setting this option to true will cause <I>Galaxy.inc</I> to output all the random
|
|
option values it uses to POV-Ray's debug stream. You can then use the +GD
|
|
command-line switch, or the Debug_File INI file setting, to direct the
|
|
debug stream to a file. This file can then be altered as desired, and
|
|
included directly into your scene before including <I>Galaxy.bg, Galaxy.obj</I>,
|
|
and/or <I>Galaxy.sf</I> (see the <I>Rand.pov</I> and <I>Rand.ini</I> files for an example of how
|

This option specifies the type of nebula pigment mapped to the sky_sphere.
|
|
Possible values are:
|
|
|
|
<UL>1 - Default nebula
|
|
<BR>2 - Light reflection nebula
|
|
<BR>3 - Nebula criss-crossed by dark gas lanes
|

<BR>5 - Dense reflection nebula
|
|
<BR>6 - Milky Way pattern
|
|
</UL>
|
|
|
|
<P>Values 1 to 5 correspond roughly with the nebulae created by <I>Galaxy.obj</I>
|
|
(see <A HREF="#galaxy_object_name">galaxy_object_name</A>). If you don't want a background nebula, set this option
|
|
to false. The default <I>galaxy_bgnebula</I> value is 6
|
|
|
|
<P><A NAME="galaxy_nebula_sphere"></A>
|
|
<B>galaxy_nebula_sphere</B>
|
|
<HR>
|
|
Use this option to create a large sphere (the radius is specified by the
|
|
<A HREF="#galaxy_distance">galaxy_distance</A> option) mapped with a nebula pigment. Possible values are
|
|
1 to 5, corresponding to the <A HREF="#galaxy_bgnebula">galaxy_bgnebula</A> option. If you don't want a
|
|
nebula sphere, set this value to false.
|
|
<BR>The default <I>galaxy_nebula_sphere</I> value is 1
|
|
|
|
<P><A NAME="galaxy_nebula_ambient"></A>
|
|
<B>galaxy_nebula_ambient</B>
|
|
<HR>
|
|
Use this option to change the ambient light value of the nebula sphere.
|
|
The default <I>galaxy_nebula_ambient</I> value is < 1, 1, 1>
|
|
|
|
<P><A NAME="galaxy_colour options"></A>
|
|
<B>galaxy_colour1, galaxy_colour2, galaxy_colour3</B>
|
|
<HR>
|
|
Use this option to set the RGB colour value used to create the galaxy
|
|
background pigments. For a monochromatic galaxy scene, only declare
|
|
the first option; for a scene that uses two colours declare both
|
|
<I>galaxy_colour1</I> and <I>galaxy_colour2</I>. Finally, to add another colour to
|
|
the galaxy pigments declare all three galaxy_colour options.
|
|
<BR>The default <I>galaxy_colour1</I> value is < 1, 1, 1> (White).
|
|
|
|
<P><A NAME="galaxy_star_colouration"></A>
|
|
<B>galaxy_star_colouration</B>
|
|
<HR>
|
|
This option sets the colour saturation used by the six background star
|
|
pigments, and by the Milky Way pigment. Good values range from 0 (no
|
|
colour) to 1 (complete colour). An interesting effect can be achieved by
|
|
using negative numbers, which result in the stars being the opposite colour
|
|
to the nebulae and other objects in the galaxy scene.
|
|
<BR>The default <I>galaxy_star_colouration</I> value is 0.2
|
|
|
|
<P><A NAME="galaxy_pattern_scale"></A>
|
|
<B>galaxy_pattern_scale</B>
|
|
<HR>
|
|
Use this option to alter the size of the patterns used to create the
|
|
galaxy background pigments. Changing this option does not alter the general
|
|
shape of the pigments; it only changes the scaling of the patterns used
|
|
within each pigment. The default <I>galaxy_pattern_scale</I> value is 1
|
|
|
|
<P><A NAME="galaxy_pattern_origin"></A>
|
|
<B>galaxy_pattern_origin</B>
|
|
<HR>
|
|
Use this option to translate the origin of the patterns used to create the
|
|
galaxy background pigments. Changing this option can completely alter the
|
|
shapes created by the pigments, and can be changed gradually within an
|
|
animation to create dynamic nebulae, etc.
|
|
<BR>The default <I>galaxy_pattern_origin</I> is < 0, 0, 0>
|
|
|
|
<P><A NAME="galaxy_turb_origin"></A>
|
|
<B>galaxy_turb_origin</B>
|
|
<HR>
|
|
Many of the galaxy pigments use some sort of turbulence; changing this
|
|
option translates the origin of the turbulence before it is applied to the
|
|
pigment. You can use this option to alter the shapes of various pigments,
|
|
or to animate the turbulence applied to the pigments.
|
|
<BR>The default <I>galaxy_turb_origin</I> is < 0, 0, 0>
|
|
|
|
<P><A NAME="galaxy_declare_only"></A>
|
|
<B>galaxy_declare_only</B>
|
|
<HR>
|
|
Setting this option to true stops <I>Galaxy.bg</I> from actually creating the
|
|
sky_sphere or nebula sphere to which the galaxy background pigments are
|
|
mapped. Instead, the file declares each of the 12 pigments separately, so
|
|
that you can then use them in the ways you use any other pigment. The
|
|
pigment names are BGStars? (from 1 to 6), BGNebula? (from 1 to 5), and
|
|
BGMilkyWay. Each of the pigments is designed to be used at unit size, but
|
|
they can be scaled or transformed any way you want, eg:
|
|
|
|
<P><CODE>#declare galaxy_declare_only = true;
|
|
<BR>#include "GALAXY.BG"
|
|
|
|
<P>sky_sphere {
|
|
<BR>pigment {BGStars3}
|
|
<BR>pigment {BGMilkyWay rotate z * 45}
|
|
<BR>pigment {BGNebula5 scale 2}
|
|
<BR>pigment {BGNebula1 rotate < 60, 50, 0>}}
|
|
|
|
<P>box {< -1, -1, -1>, < 1, 1, 1>
|
|
<BR>pigment {BGStars6} finish {phong .5}}</CODE>
|
|
|
|
<P>Note that setting <I>galaxy_declare_only</I> to true is the same as setting
|
|
<A HREF="#galaxy_bgstars">galaxy_bgstars</A>, <A HREF="#galaxy_bgnebula">galaxy_bgnebula</A>, and <A HREF="#galaxy_nebula_sphere">galaxy_nebula_sphere</A> to false.

Use this option to increase or decrease the size of the star objects. By
|
|
default the stars are designed to look best when rendered at resolutions
|
|
between 320x240 and 640x480; you may wish use smaller numbers for larger
|
|
resolutions, and vice-versa.

|
<P><A NAME="star_distance"></A>
|
|
<B>star_distance</B>
|
|
<HR>
|
|
The star objects are arranged around a large sphere; this option sets the
|
|
radius of this sphere. The default value is 20000, which should be
|
|
sufficient for most scenes and animations. If the rest of the objects in
|
|
your scene are this size or larger, you may need to increase this value.
|
|
However, values that are too large may result in disappearing objects, or
|
|
cause POV-Ray to crash when rendering the scene.
|
|
|
|
<P><A NAME="star_spread"></A>
|
|
<B>star_spread</B>
|

This option sets the difference between the distances to the closest
|
|
(largest) star and the farthest (smallest) star. The option is expressed
|
|
as a percentage of the <A HREF="#star_distance">star_distance</A>, eg: the default value of 1 means that
|
|
the stars lie somewhere between 20000 and 40000 units away (40000 being
|
|
equal to 20000 plus 20000 times 1). Setting this option to 0 would result

This option sets the ratio of large (close) stars to small (far) stars.
|
|
The default value of 1 results in equal numbers of each. Values larger
|
|
than 1 give more large stars, while values smaller than 1 give more small
|

Use this option to move the galaxy object and cluster objects. The
|
|
x-component of this option specifies the altitude of the objects, while the
|
|
y-component specifies the azimuth of the objects. The z-component is
|
|
ignored. The default value of < 0, 0, 0> positions the objects directly
|
|
perpendicular to the z-axis. North lies along the z-axis and up lies along
|
|
the y-axis. Therefore, < 90, 0, 0> positions the object directly above the
|
|
origin, and <-90, 0, 0> positions the objects below the origin. < 0, 90, 0>
|
|
positions the objects to the east (along the x-axis), < 0, -90, 0> positions
|
|
the objects to the west (along the negative x-axis), and < 0, 180, 0>
|
|
positions the objects to the south (along the negative z-axis). You can
|
|
combine these two movements using the <I>galaxy_object_position</I> value to place
|
|
the galaxy object and cluster objects anywhere in the sky.

In addition to a single galaxy object you can create a cluster of randomly
|
|
positioned, sized, and coloured objects. Use this option to select which
|
|
object you wish to use for the cluster, using the same selection as
|
|
the <A HREF="#galaxy_object_name">galaxy_object_name</A> option. If you don't want to create

cluster objects. The option is expressed as an angle, where 0 results in
|
|
all the objects being clustered at the same position, while 360 spreads the
|
|
objects across the entire sky.

This section contains some common problems you might encounter while using
|
|
the Galaxy Include File package, and instructions on how to fix these
|
|
problems.
|
|
|
|
<P><HR>
|
|
<B>Q) POV-Ray crashes when I try to render my galaxy scene?</B>
|
|
<BR>A: This may be caused by objects being larger than POV-Ray's allowed limit.
|
|
To make the objects smaller, try decreasing the <A HREF="#galaxy_distance">galaxy_distance</A> value
|
|
(the default is 10000), and also the <A HREF="#star_distance">star_distance</A> value if you have
|
|
declared this separately. If reducing this value doesn't help, try
|
|
reducing the <I>max_trace_level</I> of your scene; the Galaxy Include File
|
|
automatically increases the value for each object it creates, so add
|
|
the line:
|
|
|
|
<P><CODE>global_settings {max_trace_level 10}</CODE>
|
|
|
|
<P><B>after</B> including any of the <I>Galaxy.*</I> files.
|
|
|
|
<P><HR>
|
|
<B>Q) POV-Ray crashes before even starting to render my galaxy scene?</B>
|
|
<BR>A: This is probably caused by a lack of memory; try decreasing your
|
|
<A HREF="#star_count">star_count</A> value, or your <A HREF="#galaxy_cluster_objects">galaxy_cluster_objects</A> value if they
|
|
are quite large. Otherwise, check the error message POV-Ray gives
|
|
you; you have probably tried to redeclare an option that has
|
|
already been used by one of the Galaxy Include Files; ensuring that
|
|
options are always declared as the same type (eg. vectors are always
|
|
redeclared as vectors, etc.) should remove the problem.
|
|
|
|
<P><HR>
|
|
<B>Q) POV-Ray renders my galaxy scene, but it is very slow?</B>
|
|
<BR>A: This is probably caused by very large objects; try reducing the
|
|
<A HREF="#galaxy_distance">galaxy_distance</A> and/or <A HREF="#star_distance">star_distance</A> options as detailed in the first
|
|
question. Note, however, that when using many complex pigments like
|
|
those used by the Galaxy Include Files a certain amount of calculation
|
|
time is to be expected.
|
|
|
|
<P><HR>
|
|
<B>Q) I have created an animation using the Galaxy Include File, but the
|
|
stars seems to flicker annoyingly?</B>
|
|
<BR>A: This is caused by using background stars (mapped to the sky_sphere)
|
|
which are only suitable for still scenes. Try setting the
|
|
<A HREF="#galaxy_sky_sphere">galaxy_sky_sphere</A> option to false <B>before</B> including the <I>Galaxy.*</I> files
|
|
to remove the problem.
|
|
|
|
<P><HR>
|
|
<B>Q) I am using the <I>galaxy_pattern_origin</I> and/or <I>galaxy_turb_origin</I> options,
|
|
and there are some strange artefacts in my galaxy scene?</B>
|
|
<BR>A: This is caused by problems with POV-Ray's internal pigment mapping
|
|
functions; you should be able to fix the problem by using smaller values
|
|
for the <A HREF="#galaxy_pattern_origin">galaxy_pattern_origin</A> and <A HREF="#galaxy_turb_origin">galaxy_turb_origin</A> options.
|
|
|
|
<P><HR>
|
|
<B>Q) I have tried declaring some of the options, but nothing changes?</B>
|
|
<BR>A: Make sure that you have declared all the desired options <B>before</B>
|
|
including any of the <I>Galaxy.*</I> files. The files are not designed
|
|
to be included once at the beginning of a scene.
|
|
|
|
<P><HR>
|
|
<B>Q) How can I use the Galaxy Include File with Moray (or another modeller)?</B>
|
|
<BR>A: First export your scene from your modeller to a POV file. Then just add
|
|
your desired galaxy options to this file, and include the desired
|
|
<I>Galaxy.*</I> files before rendering the scene. If your modeller uses a
|
|
right handed coordinate system (like Moray) declare these two options
|
|
before any others to ensure that the galaxy objects are positioned
|
|
properly:
|
|
|
|
<P><CODE>#declare galaxy_distance = < -1, 1, 1> * 10000;
|
|
<BR>#declare galaxy_rotate = < -90, 180, 0> ;</CODE>
|
|
|
|
<P><HR>
|
|
<B>Q) I want to fly around a galaxy I have created, but this doesn't seem possible?</B>
|
|
<BR>A: This is because the galaxy objects are designed to generally be viewed in the background, and so they are placed at a great distance from the other objects in a scene.

You can, however, use any of the galaxy objects just as you would any other object in POV-Ray, so that it can translated, rotated, scaled, etc.
|
|
Just use the <A HREF="#galaxy_declare_only">galaxy_declare_only</A> option to create the <CODE>galaxy_object</CODE>, eg:
|
|
|
|
<P><CODE>#declare galaxy_colour1 = < 1.3, 1.2, .9> ;
|
|
<BR>#declare galaxy_colour2 = < .4, .8, 1> ;
|
|
<BR>#declare galaxy_cluster_name = ""
|
|
|
|
<P>#declare galaxy_object_name = "Galaxy3"
|
|
<BR>#declare galaxy_object_flatten = 0;
|
|
<BR>#declare galaxy_declare_only = true;
|
|
<BR>#include "Galaxy.obj"
|
|
<BR>object {galaxy_object rotate x * 90 scale 10}
|
|
|
|
<P>camera {location < 1, 2, -3> look_at < 0, .5, 0>}</CODE>

<B>Q) I rendered my galaxy image using anti-aliasing and all the stars disappeared?</B>
|
|
<BR>A: This is usually the result of using the <I>Galaxy.bg</I> file to create stars as a pigment on the sky_sphere.
|
|
Stars created in this manner will not work well with anti-aliasing, and it is usually a good idea to set the <A HREF="#galaxy_bgstars">galaxy_bgstars</A> option to false to remove these background stars if you plan to render the image with anti-aliasing turned on.
|
|
In their place, you should use the stars created by <I>Galaxy.sf</I>, as these are actual objects with pigments that have already been anti-aliased.
|
|
The best settings for a scene usually depend on the rendering size, but for an 800x600 image these settings work quite well:
|
|
|
|
<P><CODE>#declare star_count = 5000;
|
|
<BR>#declare star_scale = .5;
|
|
<BR>#include "Galaxy.sf"</CODE>
|
|
|
|

|
|
<B>Q) I can't get media to work with the Galaxy Include Files?</B>
|
|
<BR>A: Due to the way the Galaxy Include Files create the galaxy objects and stars, the results obtained using POV-Ray 3.1's media can be unpredictable.
|
|
Part of the problem is caused by the galaxy objects usually being at a great distance from the other objects in a scene, which makes it very difficult for POV-Ray to calculate accurate media interactions.
|
|
One solution is to decrease the <A HREF="#galaxy_distance">galaxy_distance</A> option to bring the galaxy objects closer to the camera, although this can make it difficult to place other objects correctly.
|
|
A better solution might be to use localised media container objects, rather than atmospheric media, to only place the media in those sections of the scene that it is required for.
|
|
This should give you more control over the media interactions in your scene, and possibly increase the rendering speed as well.
