Image Description, by Ilian Stoianov



- real-time
- light maps
- bump maps
- vertex lighting
- ray traced terrain
- an my old work dated 1998
- that's all

Ilian,

your description says the terrain is ray-traced? Can you expand on that? Does that mean the image you posted is a raytraced heightmap, or is it constructed from polygons? Does the image come from a realtime simulation? Do you intend to post a webpage providing more detail?

I'm guessing that by ray traced, he means pre-computing the lighting using a ray tracing, since it doesn't make too much sense to use lightmaps when the image is generated using a ray tracer.

Actually, I think he means a raytraced voxel. Although it looks a bit poly-ish :)

He may use raytracing to do vis checking for the landscape polygons.

He's says he uses lightmaps and vertex lighting - possible yes, likely no.

ops, I missed my IOTD, working at our last (hunting :)) game

- it is real-time simulation... ie. you can fly above terrain etc.

- it is fully polygonal - no voxels :)

- ray-tracing is used when terrain data is prepaing - I use a kind of ray-traced height field

- light-maps are pregenerated by ray-tracing & material applying

- bump mapping is a just a kind of normal map applied by texture modulation

- it uses a kind of projective view-frame oclussion algorithm


- feel free to send me emails if you have more questions
