I'm rendering a big land mass to be viewed from high altitude (40+ km), so I need satellite view style textures to be generated on the fly. The per vertex attributes I've got are:
Biome (forest, snow, desert, mountain, etc)
Question is, is this even possible by solely shader code without any textures to sample from? It's downright impossible to find a decent looking texture pack for satellite view style textures. So far all techniques I've found were based on generating textures on existing terrain data, what I need is a procedural way to generate those on the fly per arbitrary terrain.
This is more or less the looks I'm aiming to achieve with already generated mesh and more biomes(tundra, desert, bare, shrubland, etc) and perhaps more "zoomed in":
