Very cool to see SOARX in Panda3d. Well, I’m on Linux, so I didn’t actually see it 
. I believe this is the same thing that is used in Delta3D.
IIRC Perlin noise is used in SOARX for the close up details. The other day I noticed in Panda’s documentation that it has a buildin class for Perlin noise. Did you use that?
Sadly my C++ is not good enough to quickly port memory mapping
.
Question: mipmapping usually refers to creating lower resolution versions of something with high detail. The SOARX algorithm creates a higher resolution mesh than the terrain data. Does geomipmapping do that as well?
