Stl2pov is a tool that reads STL files and can output Povray grids. Tested STL files generated through Pro/engineer.
Stl2pov 2.5.0 for a wrong binary STL file reading is corrected, face is the normal first vertex problem. When the POV file is written, the correct coordinate system is converted and applied (swap x and y coordinates).
2.5.0:bug fixes. Do a coordinate transformation to fix the mirrored part bugs when writing POV files. Fix reading binary files. 2.4.4:build infrastructure tweaks mostly. 2.4.3:fix reading big binary files on Windows. 2.4.2:reduced some errors to warnings. Made the somewhat more informative. 2.4.1:add status reporting to monitor progress, especially on the big files. 2.4.0:add option to set even distance inclusive vertexes this are to is the assumed. 2.3.0:follow the new syntax for povray:use ' triangle ' instead of ' facet '. 2.2.0:changed to Bsd-style license. Makefile changed to builds with BSD or GNU make. 2.2.1:small changes for building in FreeBSD ports. 2.3.0:chase mesh syntax change in Povray.
