Blender Maths
I have recently started a group in Facebook, namely Blender Maths. It is a group focusing on all levels of maths inside Blender, from the easiest examples with few nodes to the toughest maths used in physics simulations like stormy seas, rainstorm, blizzards, eruptive volcanos, etc.
This group appeals to beginners, intermediates and experts.
Black-belt mathematican and intermeidates alike, please join and show your beastly badass maths in Blender Maths, FB group. Beginners, if you are interested in Blender maths, please join. You'll love sources for brainpicking.
