hi riemer... thx for your tutorial..

i want to ask something about this code


terrainVertices[jj + ii * terrainWidth].TexWeights.X = MathHelper.Clamp(1.0f - Math.Abs(heightData[jj, ii] - 0) / 8.0f, 0, 1);
                    terrainVertices[jj + ii * terrainWidth].TexWeights.Y = MathHelper.Clamp(1.0f - Math.Abs(heightData[jj, ii] - 12) / 6.0f, 0, 1);
                    terrainVertices[jj + ii * terrainWidth].TexWeights.Z = MathHelper.Clamp(1.0f - Math.Abs(heightData[jj, ii] - 20) / 6.0f, 0, 1);
                    terrainVertices[jj + ii * terrainWidth].TexWeights.W = MathHelper.Clamp(1.0f - Math.Abs(heightData[jj, ii] - 30) / 6.0f, 0, 1);


i'm confused about how we can get 8.0f, 6.0f, 6.0f, 6.0f?and what is the meaning?

e.g.
MathHelper.Clamp(1.0f - Math.Abs(heightData[jj, ii] - 0) / 8.0f, 0, 1);


sorry about bad english,,

That part of code was already explained a few times. I think riemer should re edit that part to explain more.

here is a link to a previous thread on this matter.

I also explained that part once but i can't seem to find that thread.

Hope this helps...
