Gaea is cool and everything, but what about fluvial erosion in #Blender with #GeometryNodes?

The concept rather simple:
- spawn points somewhere
- calculate a movement vector with ( N x (0,0,-1) ) x N, where N is the normal vector, sampled from the mesh surface (its a double cross product)
- update the points in a simulation zone
- accumulate the point proximity in a per-face attribute for the mesh. This requires a high res mesh
- optionally displace the mesh

#B3D #Geology #Simulation

A fantastic cosmic web #geonodes setup for Blender. It is useful for creating superstructures resembling galactic filaments – that actually run super fast.
