I am working on a video game that is attempting to provide a semi-realistic model of Mars. My starting point has been to find and use reliable geographic information to create the "model" of Mars.
I have found this global 465m Digital Terrain Model of mars. It is provided in a CUB file which I believe just represents an elevation as a height value in a large 2D image.
I was hoping someone here knows of either a formula or methodology I could follow in order to convert from a raster "heightmap" into a spherical mesh. I know how to mesh a point cloud so even if I could get help in going from a raster heightmap to a point cloud I can take it from there.
