P-152: Virtual World Concept Update 14: Spherical Terrain

I seem to have reached something of an impasse with my plan to modify T3D’s terrain engine to create a quad cube. I can get the Z axes (The height) working ok, but I can’t modify the X and Y axes, they seem to be tied into the terrain system in a way which I cannot figure out how to modify.

I have spent a lot of time working with the vertex and primitive buffers within the terrain system, but I cannot seem to modify them to accept custom X and Y values. I believe the X and Y values are tied into to the rendering algorithm in some obscure way. I had believed that the system used a simple vertex list, and I could simple change the value of the X and Y points explicitly, but this seems to not be the case.

I was very close to solving this, but it seems that at this stage a rethink is necessary.

In the below images, the generally spherical shape can clearly be seen. The large gaps are where the X any Y axes should be deformed to line up with each other. This is as far as I got with T3D’s terrain system.

I posted a topic HERE on the GarageGames forums about this issue, and received many very informative replies, the information there may be useful to someone else.
