- I've been wondering about how LightWave renders an image... it apparently
- does not, for example, waste time doing computations on polygons that are
- hidden behind other polygons (unless transparent, of course.)
- Any kind and knowledgeable soul out there care to expound on how a program
- knows what polygons to draw and what polygons to ignore? Does this involve
- the z-buffer, for example?
-
- What prompts my curiosity is a program I purchased that seems to spend an
- inordinate amount of time _not_ drawing anything. It renders visible poly-
- gons fairly quickly, then sits and draws no new pixels for a majority of
- the rendering time. I speculate that it is doing the computations for all
- polygons in the camera view area regardless of whether they are actually
- visible. Hmmmmmm... perhaps.
-
- Hoping to develop a better understanding of these 3D drawing thingys... :)
