Thank you guys for answer, i hardcoded the Matrix.
But i have another issue.
My Planet is normalized Cube with six side.
I create the Noise Value like here described:
The Noise generated for each patch, so the PixelShader needs the Coordinate of the patch (xNW, xNE, xSW).
For the root Patch ( without subedived the quadtree it´s):
nw = new Vector3(-1,0, 1); ne = new Vector3(1, 0, 1); sw = new Vector3(-1, 0, -1);
Assume this is for the TopSide of the Cube.
How i get the noise for the Front side of the Cube?
It´s a 3d noise Funtion in the Shader so how i can translate the nw, se, sw Vector to match the front side (when i pass the right Value i have no seams on the Cube Faces like:)
