Builds a bvh tree where nodes are the relevant elements of the given mesh. Configures BVHTreeFromMesh.

The tree is build in mesh space coordinates, this means special care must be made on queries so that the coordinates and rays are first translated on the mesh local coordinates. Reason for this is that bvh_from_mesh_* can use a cache in some cases and so it becomes possible to reuse a BVHTree.

free_bvhtree_from_mesh should be called when the tree is no longer needed.

Builds a bvh tree where nodes are the given tessellated faces (note: does not copy given mfaces!).

Parameters

vert_allocated	if true, vert freeing will be done when freeing data.
face_allocated	if true, face freeing will be done when freeing data.
faces_mask	if not null, true elements give which faces to add to BVH tree.
faces_num_active	if >= 0, number of active faces to add to BVH tree (else will be computed from mask).

Builds a bvh tree where nodes are the given vertices (note: does not copy given mverts!).

Parameters

vert_allocated	if true, vert freeing will be done when freeing data.
verts_mask	if not null, true elements give which vert to add to BVH tree.
verts_num_active	if >= 0, number of active verts to add to BVH tree (else will be computed from mask).
