3d cellular automata (list- and layer-based) creates three voids around a tree point cloud scan. 200 pixel x 200 pixel * 200 slides (eight times, from bottom two top). CA starts from tree bark, green is more likely to win in y-direction (minus), green int x-direction (minus) and blue in z-direction (minus). White wins with specific distance to bark.

The beam-growing algorithm finds a solution for contrasting objectives. It constantly calculates new growing directions based on closest neighbors, closest targets (design intention), border / branching distance, gravity and neighbor structures / trying to connect in the direction of beam orientations. The algorithm connects all desired goals and still is able to react to design intentions by using implemented weights.
