Neural Cellular Automata: Operating on Mesh Lattices and Triangle Primitives
By
Ehsan Pajouheshgar1,
Recycled flavour. You've tasted this bagel before.
Summary
This article discusses Neural Cellular Automata (NCA), a computational model that operates on a coarse lattice of cells, using mesh vertices as an example. It explains how sampling points inside triangle primitives correspond to NCA cells, with local coordinates expressing positions within the primitive. The content appears to be a technical excerpt from a larger piece about applying cellular automata concepts to pixel/image processing.
