- .SH NAME
- exp_pov \- Persistence of Vision Ray Tracer v2.0 (POV-Ray) geometry export
- filter.
- .SH SYNOPSIS
- .PP
- This man page describes the options specific to the POV-Ray geometry export
- converter.
- .PP
- .SH EXAMPLE CONVERSION SYNTAX
- .PP
- To convert a 3D Studio file to POV-Ray using the default parameters listed
- in the setup.ini file:
- .IP
- pt -i 3ds -o povray filename.3ds
- .PP
- .SH OVERVIEW
- .PP
- This geometry export converter writes out the lights, cameras, materials
- and geometry to a Persistence of Vision Ray Tracer (POV-Ray) geometry
- file, version 2.0 format. POV is a popular public domain ray tracer that
- is available on many BBSs and Internet sites.
- .PP
- .SH COMMAND LINE OPTIONS
- .PP
- The following options are specific to this import converter:
- .TP
- -o povray
- This is the mandatory command line option which specifies that the data
- is to be exported using the POV-Ray format converter.
- .PP
- .SH CONVERSION NOTES AND LIMITATIONS
- .PP
- All polygons will be converted to triangles with optional vertex normals.
- .PP
- The current default camera will be output as the POV-Ray camera (perspective
- camera only).
- .PP
- Only point and spot lights will be output. Directional lights are not
- supported by the POV-Ray v2.0 file format.
- .PP
- Many attributes will be output to a POV-Ray material definition, such
- as the finish attributes (shininess, ambient, diffuse, specular,
- index-of-refraction, phong values, etc), the pigment color, and an
- optional 2d bitmap texture link.
- .PP
- POV-Ray only supports Targa, IFF and 'dump' bitmap image formats for
- texture mapping. However, this converter understands many more formats (such
- as TIFF, JPEG and BMP). If the bitmap output type is not Targa, IFF or 'dump'
- then the converter will write 'dump' as the file format. You will probably
- have to hand edit the "image_map" command to specify the correct bitmap
- type and the correct directory location of the texture map file.
- .PP
- The current POV-Ray file format does not allow u/v texture coordinates
- to be associated with the triangle geometry. Therefore, no u/v texture
- coordinates are output. Instead, a default spherical texture projection
- method has been enabled within the "image_map" command. You can edit
- this by hand if you so desire.
