I'm afraid to report that the horrible proprietary s3 3d apis are not emulated yet, probably because of two factors:
- way too few games utilized virge API
- s3 makes horrible 3d cards anyway
i agree with you. the S3D API didnt had a chance to become popular, because of the overwhelming success of the voodoo chipset one year later.
it was also not very capable, but it introduces the first hardware 3d render techniques (billinear filtering and perspective correction).
back these days i saw a promotion screenshot of terminal velocity from S3 and i was very impressed, but never had a chance to play this game with its full glory. it would be great if dosbox could emulate the S3D API someday. 😀
EDIT: here is the one and only screenshot i found on the net from the patched terminal velocity which uses the S3D API:
