First a small introduction from a graphics website:
http://www.decew.net/OSS/timeline.phpA year ago I mannaged to crack this polygon type as can be seen in this picture:
Here the polygon is used on my searchlight. Notice how each searchlight displays different texturing, except the top circular polys which are at the same angle to the lightsource/view angle. When the camera position changes the shown texture also changes, very much like what you'd see in a reflected surface. In this respect the polygon behaves exactly as described in the introduction.
I'd like to make it clear that this isn't reflection as one would see in newer games where polygons use an additional texture, much like the TRA, which overlays the surface of an object. This poly is NOT transparent or luminescent and thusfar I've been unable to get a usefull effect out of it except for it's animated surface depending on the viewing angle. When I move further away the mapping moves up or down or jumps onto an adjacent polygon.
It's mapping parameters used on textures change according to the viewing angle but not in any way that one could use this texture on a model and retain usefull information on it, like for instance decals or numbers.
It seems to me that the texture itself should hold the relection information which then distorts according to that viewing angle. Like in the introduction the texture is more like a lightsource for the polygon and can contain any color/drawing.
This makes mapping awkward and thusfar I've not been able to create a 3D object as in the introduction. It'll take time to figure out a use for it's behaviour but it's a start. The experiment continues.
