3DS2POV Version 1.8 Oct/93
Copyright (c) 1993 by Steve Anger and Jeff Bowermaster

This program reads a 3D Studio .3DS file and writes a POV-Ray, Vivid or
Polyray raytracer scene file. Cameras, lights, spotlights, and mesh objects
are all converted. Basic material properties such as colour, reflection,
and transparency are converted however image maps and bump maps must be
converted manually.

POV-Ray users! Since POV-Ray 2.0 has now been released to the public the
default output format has been changed to POV-Ray 2.0. If you're still
using POV-Ray 1.0 you can still generate 1.0 compatible files by using
the -op1 switch.

Hardware requirements:

The 3ds2pov.exe executable requires a minimum of a 386 or a 486 with a
math co-processor. At least 2MB RAM is recommended. It's compatible with
most 386 memory managers and DPMI servers.

Syntax: 3ds2pov inputfile[.3ds] [outputfile] [options]

-snnn - Generates smooth triangles. The boundaries between triangles
are only smoothed if the angle between the triangles is less
that nnn degrees. -s0 will not smooth any triangles while
-s180 will smooth all triangles. Values from -s45 to -s90
usually work well. If unspecified smoothing defaults to -s70.

-l - Specifies an include file containing texture declarations for
common 3DS materials. Up to 10 libraries can be specified.

-a - Use animation information in specified .vue file.

-fnnn - Generate frame nnn of animation (must be used with -a

-x - Exclude this object from the conversion.

-b - Replace this object with a box during the conversion. If no
object is specified then all objects will be affected.

+i, -i - Turn internal bounding on or off for POV-Ray. If not specified
internal bounding defaults to on for POV-Ray 1.0 and off for
POV-Ray 2.0.

+v, -v - Turn verbose status messages on or off (off by default).

-op - Output to POV-Ray 2.0 format (default)
-op1 - Output to POV-Ray 1.0 format
-ov - Output to Vivid format
-ol - Output to poLyray format
-or - Output to Raw triangle format.

Note: When specifying object names on the command line, object names that
contain spaces must be enclosed in double quotes. e.g. -x"BEACH BALL"

3ds2pov robot

assumes the input file is robot.3ds and outputs to robot.pov and in the current directory. The file robot.pov will contain
the camera, light sources, and list of materials used (basically everything
you may want to edit) and contains the triangle mesh data.

Predefined materials in will be automatically used if the
names match (case is important), otherwise 3ds2pov will generate a material
definition based on the information in the .3DS file. The files and
v3ds.vs are included as examples of how to setup material libraries for
POV-Ray and Vivid.

Materials Conversion:

The 3DS to raytracer material properties conversion is functional but far
from perfect. Basic material properties such as object colour, reflection
and transparency are automatically converted but image maps, bump maps, and
reflection maps are ignored. In most cases the converted material should
match the original reasonably well however it's not uncommon for some
materials to come out completely wrong. Expect to have to do some manual


3ds2pov doesn't use 3D Studio's smoothing group information and instead
does it's own smoothing. The amount of smoothing applied is controlled by
the -s parameter and specifies the maximum angle that will be smoothed. The
default of -s70 usually works for most scenes but you may find that some
scenes require more or less smoothing. This parameter works just like the
Auto Smooth option in 3DS.


The animation information is exported from 3ds via a .vue file that can
be created in the 3DS keyframer (Render/Setup/Make .VUE). By specifying the
name of the .vue file and a frame number 3ds2pov will generate a scene file
for that specific frame.

e.g. 3ds2pov robot -arobot.vue -f5

The option -arobot.vue tells it to get the animation information from file
robot.vue and option -f5 tells it to render frame #5. To generate a whole
animation you can create a batch file that runs 3ds2pov and the raytracer
for each frame in the animation. The program 3dsani is included to make the
generation of this file a little easier.

Syntax: 3dsani inputfile [options]

-a - Specifies the name of the 3ds animation (.vue) file.
If unspecified defaults to inputfile.vue.

-t - Specifies the name of the template (.tpl) file.
If unspecified defaults to inputfile.tpl.

-o - Specifies the name of the output (.bat) file.
If unspecified defaults to inputfile.bat.

-snnn - Start animation at frame nnn. If unspecified the start frame
is taken from the .vue file.

-ennn - End animation at frame nnn. If unspecified the end frame is
taken from the .vue file.

-pnnn - Render every nnn'th frame. If unspecified defaults to 1.

3dsani robot -tani1.tpl

generates a batch file named robot.bat that will execute 3ds2pov and povray
once for each frame of the animation. The beginning and ending frame numbers
are determined from the file robot.vue. The format of the batch file is
determined from the template file ani1.tpl. Basically the template file is
duplicated once for each frame but with all occurrences of the characters $
and # replaced by the file name and frame number respectively. Several
sample template files are included which can be tailored to your specific

Environment Variable:

If you find that you're often using the same command options over and over
again you can set up your default command line options in the 3DS2POV
environment variable. e.g. If you generally use Vivid as your renderer you
may want to add the following line to your autoexec.bat:

set 3DS2POV=-ov

Commands specified in the environment variable will be overridden by those
specified on the command line.

Known Bugs/Problems:

Orthogonal/user viewports, and camera roll are not implemented.

Solid background colours work with POV-Ray and Polyray but not with Vivid.

Fog works with POV-Ray but not with Polyray or Vivid.

Gradient and image mapped backgrounds are not implemented.

The camera field-of-view conversion isn't perfect. The rendered FOV will be
close to the original but it won't be exact.

If the 3DS file contains more than one camera it'll use the first one it
comes across. All additional cameras will be commented out.

There is a known problem with the version of POV-Ray 1.0 that was shipped with
the Image Lab book that prevents smooth triangles from rendering. If you have
this version you can download the latest version from CompuServe or a local
BBS (look for POVIBM.ZIP).

POV-Ray 1.0 doesn't handle refraction very well for triangle meshes. If you
want realistic refraction in your image you should output to POV-Ray 2.0 with
no bounding boxes (2.0 will bound the scene itself). Also only a single
material should be used on each refracting object (don't apply materials
to individual faces).

The protected mode version of this program was compiled with DJGPP 1.10,
DJ Delorie's DOS port of the GNU C/C++ compiler. Source code and executables
for this compiler and the DOS extender can be obtained from the ftp site in directory ~ftp/pub/msdos/djgpp. DJGPP can also be
found on CompuServe and many BBS systems.


For a while I've been playing around with the idea of adding one or two
radiosity packages to the list of supported renders but I don't know much
about what radiosity packages are available. Anyone have a favorite
radiosity program (preferably one that's freely available). Is radiosity
rendering of multi-1000 triangle meshes practical on desktop computers?

Revision History:

Ver. 1.8 Default output format is now POV-Ray 2.0 (if you're still using
POV-Ray 1.0 use the -op1 switch). Added automatic conversion of
basic material properties (colour, relfection, transparency).
Selected objects can be converted as boxes for testing. Default
smoothing changed from 60 degrees to 70 degrees. The executable
is now DPMI compliant and should work under OS/2 and Windows.

Ver. 1.7 Directly reads .3DS files instead of the slow/bulky .ASC files.
Added support for 3DS 2.01 .vue files and fixed some bugs with
the .vue file parsing. Added morphing. Added support for the
Polyray raytracer. Textures now move with animated objects.
Default switches can be set in the 3DS2POV environment variable.

Ver. 1.6 Animation support added. Added support for Vivid output.
Identifiers that begin with a digit are now prefixed with
the letter 'N' rather than an underscore (for compatibility
with Vivid). Fog works (I think).

Ver. 1.5b Correctly handles spotlight hotspot parameter. Multiple texture
libraries can be specified. A bug that occasionally resulted in
a zero length include file fixed.

Ver. 1.5 Fixed bug with spotlight falloff parameter.

Ver. 1.4 Modified for POV-Ray 1.0 output format. Uses 1.0's new box
primitive for bounding. Bounding ellipsoids are no longer used.
Added support for spotlights.

Ver. 1.3 Modified the parser to handle 3D Studio 2.0 ascii dump files as
well as 1.0. Added limited support for automatic texture handling.

Ver. 1.2 Added the octree bounding code from txt2pov. The parser is now a
little more bullet proof and should be able to handle minor
changes in the format of the ascii dump file.

Ver. 1.1c Fixed the bug I inadvertently added to the txt output in v1.1b.
Added texture names to the txt output. These are used by v1.3 of
txt2pov (formerly txt2dkb). The 32 bit version no longer requires
removal of 386 memory managers. SA

Ver. 1.1b Minor source code modifications to allow program to compile with
GNU C 32 bit compiler. Note: The 32 bit version (3ds2dkbx.exe)
requires a 386 /w 387 or a 486 to run. 2M or more RAM is
recommended. Any 386 memory managers (386^Max/QEMM, etc) must be
removed before the 32 bit version will run. SA

Ver. 1.1 RIGHT <1.33 0.0 0.0 > in VIEW_POINT produces much better circles.
COLOR for the light sources moved outside the TEXTURE block (oops.
I'm still learning...) Jeff

Ver. 1.0 Original release, DKB, simple TurboC parser by Jeff.
Very slow by itself, workable when used in conjunction with
Steve's optimizing bounder. (TXT2DKB).
