Likely the most versitle shareware 3D conversion utility that you will find anywhere. It is actively maintained and developed and has support for most major 3D file formats. It also include direct support for POV-Ray and Moray plus the author has plug-ins available for Moray for direct import capabilitites.

A free POV-Ray compatible 3D conversion program. It offers support for multiple 3D file formats and can export directly to POV-Ray 2.0 and 3.0 file format.
OBJuvPOV - Poser4 .OBJ to POV-Ray converter (early beta). This program offers conversion from .obj to .pov files and allows for maintaining texture coordinates through use of UV mapping. This feature requires Nathan Kopp's UVPov patched version of POV-Ray.
Converts from STL (Standard Triangulation Language) file and outputs a POVray mesh. It creates either triangles by default, but can generate smooth_trianges; can read binary STL files, and has an option to smooth the generated mesh. Executables for Unix and Windows.

3DS2POV V1.80 - This free program can convert your binary 3D Studio 3DS file in POV 1.0, POV 2.0 including basic material parameters (color, ambient, diffuse, reflection, transparency) and smoothing. It also supports the output of RAW (useful for POVLAB), Vivid and Polyray. Supports animation ! By Steve Anger
AccuTrans 3D - Home
AccuTrans 3D provides accurate translation of 3D geometry between the file formats used by many popular modeling programs. Positional and rotational information for the 3D meshes is maintained. Also many material attributes, such as color, index of refraction, reflection, specularity and Phong shading, are transferred between the files. Textures are not currently supported. The program has been enhanced with additional features to make it more than just a 3D file conversion program. Has POV-Ray support.
AutoCAD2POV 3.0a. This is a *much* more solid package than Version 1. It is almost a total rewrite, with tons of improvements, and many objects added (converts AutoCAD colors). Win95+.

ThreeDS is a Python module for loading and displaying 3D models in the 3DStudio Max 3DS format. It comes with view3DS, a simple model viewer written in Python.
3D Exploration - 3D viewer
3D Exploration is a viewer for Windows 95, 98 and NT with Explorer-like interface and Open GL hardware accelerator support. It allows you to browse many popular 3D file formats - 3D Studio, LightWave, Caligari, Direct X, AutoCAD and many other, plus common 2D file types. Shareware
asc2tga and Smooth
When rendering landscapes from maps with POV-Ray you often have an elevation matrix stored as an ASCII matrix. asc2tga converts such a file into a POV readable heightfield in TGA format. Smooth can magnify this heightfield using bicubic interpolation.
C2HTML - Converts sourcecodes (e.g. C, C++, POVray) to HTML i,cl. syntax highlighting.
Code to HTML converter
Now including povray source. Process source code to HTML with colored syntax for linux. By Peter Palfrader
dxf2pov and dxf2wrl
Win32 command-line applications written in C.
dxf2rad - Convert Geometry from DXF to RADIANCE
Dxf2rad is a command line utility for translating geometry data from the DXF file format into the format understood by the RADIANCE lighting simulation package. Dxf2rad shares a lot of code with Radout, an Autocad extension to export geometry directly from within a drawing. It was written to support the architectural lighting design software package Rayfront, which offers complete control over all parameters of RADIANCE simulations.
Programm converts Eagle-Layout-File (www.cadsoft.de) to a POVRay-Scene. Predominantly for generating 3D images based upon 2D representations of printed circuit boards.
