Does anybody have some experience with displaying
head-light lobes on a textured road?
(ONYX/RE with O.S. 5.3)
A "spotlight approach" is going to work
if each section of the road is represented by
a set of properly textured and lighted,
small "sub-polygons".
Hence light computations are performed on
a vertex basis, the more sub-polygons are created
the better head-light lobes effect can be
achieved. But, it is going to be difficult
to match texture samples applied to e.g.
a curved road.
"Open GL Programming Guide" (paragraph 9) says
that the "q Coordinate method" might be used.
Is it possible to apply this idea to a real
time driving visualization?
Any thoughts?
