Pov4Grasp patch    Grasp2pov conversion utility



Pov4Grasp patch

Updated October 12, 2000



  Disclaimer

Pov4Grasp is a patch version of the Persistence of Vision Ray Tracer (POV-Ray)web  which contains all of its original features without any particular limitation. Use at your own risk since I provide NO WARRANTY with it. For bug reports, comments or suggestions, you are welcome to send me an e-mail, but PLEASE DO NOT ASK THE POV-RAY TEAM TO SUPPORT THIS UNOFFICIAL VERSION.

 


  Source distribution

Version:
pov4grasp-1.31 for UNIX/Linux platforms

Distribution:
tarball archive (.tgz or .tbz2)

Install:

  1. Unzip and untar the archive as usual (e.g. 'tar xvzf file.tgz')
  2. Compile the external libraries if needed (zlib and libpng)
  3. Compile the patch as described in the POV-Ray docs (e.g. 'make newxwin')

Notes:
The archive file contains source code for the patched POV-Ray including the external libraries (zlib/ and libpng/) and the unix/ directory. You may disable the patch code by commenting the "#define Pov4GraspPatch" line near the top of the frame.h file. Compiling will produce either pov4grasp, s-pov4grasp or x-pov4grasp executables.

  Executable binaries

Version:
pov4grasp-1.31 for UNIX/Linux platforms (X windows display)

Distribution:
Gzip'ed (.gz) or Bzip2-compressed (.bz2) executable

Install:

  1. Save with .gz or .bz2 extension (Netscape may remove it)
  2. Unzip the file as usual (e.g. 'gunzip file.gz')
  3. Check that the file is executable (e.g. 'chmod +x file' if not)

Notes:
I only provide the x-pov4grasp version, which should be the most useful. Executables are linked against dynamic libraries. Since I have no access to any other platform, use the source distribution for unsupported architectures. More informations on the Pov4Grasp features are given in the text documentation.

Grasp2pov conversion utility

Updated July 12, 2000



The grasp2pov conversion utility is a console tool which reads a GRASP binary surface file and writes a POV-Ray 3.1 include file to standard output. The Pov4Grasp project is actually the extension of this tool. It has been used to test the draft of the grasp_surface object of my patch, and then to perform some benchmarks. A MegaPOV output is also possible.

This tool is available for those who prefer to use the official version of POV-Ray. However you will miss the advantages of using Pov4Grasp itself in terms of speed, file size and memory. Beware, it may write huge include files depending on your GRASP data. Also only one surface property (potentials, curvatures, ...) can be mapped at a time. For more information, here is a copy of the README file provided within the distribution.
