Rivers, canyons and cliffs


I added two additional texture levels (one for rivers, and one for canyons) and modified the planets shaders code to shape the contours generated by the fractals functions (fbm, iqTurbulence) and finally obtain rivers and high reliefs carved canyons. See pics bellow.

Hello, Some recent screengrabs here.

I had recently fun coding an embryonic gameplay in my planet demo : once landed with my 300 meters long cargo, I can leave the ship and use my foot to spin around, in an classical FPS control mode and point of view

Water rendering

I just integrate some shaders to improve water/oceans surface rendering. There's also a tiny waves animation using perlin noise.

Clouds

It's now time to work on clouds \o/

Before turning to the integration of the volumetric clouds system, adding a global clouds layer, with a slight embossed effect.

planet's topography controlled

Randomized fbm and iq turbulence are nice, but I also need a way to control planet's topography and continent's shape. 

I therefore added some specialized code to do it : submitting the following bitmap, containing an example of continent map, to the new shaders  :



Black pixels (0,0,0) simply represents oceans and rivers; green channel is dedicated for plains and continents coasts altitude, and blue channel is reserved for areas where mountains are authorized; I get the following results:
