[DX] Simple Cell Data From Vertex Data

Recommended Posts

DJTN    207
I've created a terrain mesh with the same size triangles. I store cell data for every 2 triangles. I have 60 vertices per row and 60 vertices per column. When creating the vertices I store every 6 vertices in a collection as a cell for collision detection later. The problem with this is that it creates 10 cells per row and not 60.

[b]60 vertices / 6 = 10 cells. [/b]I should have 60 cells.

Since each cell shares vertices from another, how can I calculate this? How can I determine which vertices to re-use when creating the next cell?

I know this should be pretty easy but I'm stumped...

Wow, I feel stupid. Last night, right before I fell asleep it came to me. I don't need to store the cells, I can recreate the two triangles from the vertex data and test for collision using a point to triangle method and the current world position of the object I'm testing.
