ConceptS-Octree / Sparse Octree
Sparse Octree
A sparsified octree variant proposed in OctLLM that compresses sequence length by randomly clearing second-to-last-layer nodes and their descendants, while retaining shape outline, coordinate, and depth information. This structure is designed to improve computational efficiency in 3D geometric modeling tasks.

OctLLM designed a Sparse Octree (S-Octree) that randomly clears nodes at the second-to-last layer and omits their descendants, retaining shape contours to shorten the sequence.
