swapinterval & tmesh

[Dr. Michael M. Cohen]

A few questions from a vgx novice...

If I've got swapinterval(2), for running on 60Hz console (at 30 frames/sec)
should I put swapbuffers(1) when in 30Hz mode for NTSC output?

I'm plotting about 1000 polygons (mixed 3&4 point) using bgnpolygon,
(...n3f, v3f,...) endpolygon mode. I can do this (just barely) at 30 Hz.

How much speedup in drawing time can I expect by using triangular mesh approach?
(system is 4D/310-VGX-FX 3.3.2 16Mb)

I am computing the vertex normals myself. Can the graphics hardware
do this for me?

TIA for assistance... MMC
