vector usd_pointinstance_relbbox(<stage>stage, string primpath, int instance_index, string purpose, vector position)
Returns the relative position of the given point with respect to the bounding box of the instance in a point instancer.
<stage>
When running in the context of a node (such as a wrangle LOP), this argument can be an integer representing the input number (starting at 0) to read the stage from. The integer is equivalent to the string form referencing a particular input, e.g., “opinput:0”.
You can also use this argument to refer to a USD file (e.g., “/path/to/file.usd”), or to another LOP node’s cooked stage using the op: as the path prefix (e.g., “op:/stage/lop_node”).
primpath
The path to the primitive.
instance_index
The index of the instance whose bounding box to use.
purpose
The primitive’s purpose for which to use the bounding box (e.g., “render”).
Returns
The relative position of the given point with respect to the bounding box of the primitive.
Examples ¶
// Get the point's position relative to the bounding box of the first instance. vector pt = {1, 0, 0}; vector rel_pt = usd_pointinstance_relbbox(0, "/src/instanced_spheres", 0, "render", pt);
