Kernel

Construct an axis-aligned bounding box query against a BVH object.

This query can be used to iterate over all bounds inside a BVH. To start a query from a specific node, set root to the index of the node. The root can be obtained using the bvh_get_group_root() function when creating a grouped BVH. When root is a valid (>=0) value, the traversal will be confined to the subtree starting from the root. If root is -1 (default), traversal starts at the BVH’s global root. The query will only traverse down from that node, limiting traversal to that subtree.

param id:

The BVH identifier

param low:

The lower bound of the bounding box in BVH space

param high:

The upper bound of the bounding box in BVH space

param root:

The root to begin the query from (optional, default: -1)
