From what I know about image rendering, there are generally two types
of algorithms: those that operate in object space and those that operate
in image space. Often, object space algorithms are used to determine
visible surfaces and image space algorithms are used for display.
For my particular application, I need greater precision than obtainable
from image space algorithms (i.e. ray tracing, z-buffering).
I deal with moderately complex objects (not entire scenes) and have a need
to display them on different systems. Some may have 400 x 400 pixel displays,
some 1000 x 1000. Rather than having to ray-trace the object again for each
different display, I would rather carry a complete 2D representation of the
object (for several views) that I could quickly display on any arbitrary
system.
Since the object is originally represented in CSG format, I have a need to
construct geometrically precise 2D descriptions from 3D representations.
Does anyone have a similar need or have pointers to relevant literature?
It seems as though my problem may be outside the realm of traditional
computer graphics. I don't know.
