Calculation of Slope/Passability
Posted: 31 May 2011, 20:45
As far as I know, maps are ultimately composed of right isosceles triangles, whose vertices are defined by the heightmap, like this:
My question is how slope/passability are calculated. Is a slope defined for each triangle, or each square? Are the slopes calculated from the edges, or the faces?
Note: I need to know this for more than just testing for passability, so please don't tell me to just use tools to see the passability or whatever.
