Another Open Source VRML97 browser is Tuomas Lukka's FreeWRL, a
Perl-based effort that uses OpenGL for 3D rendering and FreeType
for font support. As such, it is one of the few VRML97 browsers that runs
under Linux, but because of its dependence on a host of secondary Perl
packages and external libraries,
it is not for the meek. Version 0.13 supported PNG, but just barely: only on
primitive shapes (Box, Cylinder, and Sphere, not IndexedFaceSet, Extrusion,
or ElevationGrid nodes), and in a test world with both PNGs and JPEGs, the
two JPEG textures appeared to be used on every textured surface, replacing
all of the PNG textures. It also did not support material transparency,
had problems with nonconvex, textured polygons, and, as a script-based
browser, was rather slow.
Version 0.17 was Tuomas's final release (December 1998); as of January
1999, John Stewart was the maintainer, and the new web site was
http://debra.dgbt.crc.ca/~luigi/FreeWRL/. Version 0.19 was the
current release as of early April 1999.
