Procedural Planet rendering?

Hi guys! I’m making a space game, for some tests i wanted to get into procedural planet rendering, i actually don’t know what the real thing is called, but thats what i call it. Heres some videos on it if you don’t know what i m talking about, (Sorry if theres a specific name for this!)

Thats one made in Unity3D, and heres a more professional one made in i think the cry engine or OpenGL with C++

Sorry if this is the wrong section, I just want a link or someone to direct me in the right way on getting started in this, I heard its extremely complicated, so directions on where to start would be nice. Thanks!

Hi man! I’m working on my thesis and I have ready (almost) my renderer using OpenGL 4.4 / C++.

Have you figured how to make this with Unity?

I’d like to integrate my work with unity, maybe as a plugin, but I don’t know where to start!

If some moderator is able to guide, I’d be very thankful!
