Protected Attributes

int split_axis: The axis based on which the split decision is made. For most BV, the axis is aligned with one of the world coordinate, so only split_axis is needed. For oriented node, we can use a vector to make a better split decision.

Vec3s split_vector

CoalScalar split_value: The split threshold, different primitives are splitted according whether their projection on the split_axis is larger or smaller than the threshold.

Vec3s *vertices: The mesh vertices or points handled by the splitter.

Triangle *tri_indices: The triangles handled by the splitter.

BVHModelType type: Whether the geometry is mesh or point cloud.

SplitMethodType split_method: The split algorithm used.
