LibVRML97/Lookat

LibVRML97 is Chris Morley's free VRML97 library, written in C++; Lookat is a simple browser based on the library. As of version 0.7.9, the library was known to compile under Linux, Solaris, and Windows 95; it should be portable to most platforms with a reasonably up-to-date C++ compiler. The Lookat sample browser (and its Motif- and GTK-based variants, xmLookat and gtkLookat) was originally specific to Unix and the X Window System, but a 32-bit Windows port was progressing quite rapidly as of January 1999.

Earlier versions had various minor texture problems, but version 0.7.9 earned a distinction shared by no other VRML browser: perfect texture-rendering compliance with the VRML97 specification for all combinations of texture types and material properties, as far as our tests can determine. The browser may have other limitations, but its PNG support is without parallel.[45]

[45] There was actually a tiny glitch: one pixel in the corner of one GIF texture was the wrong color. Oops.
