I continued building the neural visualization by implementing a neuron system by randomly placing points in a box to generating neurons based on an actual brain model. I used a point in mesh approach basically using raycasting so neurons are only placed within the brain’s geometry. The current approach works, but generating the neurons is like really slow because each position has to be checked against the brain mesh, and if it isn’t inside, the system keeps trying until it finds a valid position. Next, I’ll improve the neuron placement by making it more efficient.
