Hello,
If you look at this image:
why is it that I still see the lines between the vertices even tho I use a texture? Has it something to do with the fact that I am using Trianglelist instead of TriangleStrip or something like that?
Best Regards

vertexPosition.x = vertexPosition.x + (patch[0].sphereNormal.x * ((heightMapSample * 29429.0f) - 8200.0f));
vertexPosition.y = vertexPosition.y + (patch[0].sphereNormal.y * ((heightMapSample * 29429.0f) - 8200.0f));
vertexPosition.z = vertexPosition.z + (patch[0].sphereNormal.z * ((heightMapSample * 29429.0f) - 8200.0f));
The trick might be to stop using "points that sit in the same position" and start using indexed rendering so that there is a single shared vertex instead of a bunch of vertices that happen to be in the same spot. That said, it might be hard to do that for an entire huge mesh, e.g. if you have multiple height map textures.
Using vertices that sit in the same spot can work, but only if you're very careful to eliminate the possibility of floating point error. e.g. If your patches have different world matrices to one another, or they sample different height-map textures, or they calculate their UVs differently, then you're going to see artifacts like this.
Maybe if you post the whole vertex shader and provide detail about any differences in position calculations between patches, then that'd be useful.
For me its perspective projection problem -> you use wrong z_near and z_far values (z fighting)
.
if not that then you pick wrong texture texels in shader.
