vector usd_pointinstance_getbbox_max(<stage>stage, string primpath, int instance_index, string purpose)
Computes the largest position of the bounding box for the instance geometry.
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”).
The path to the primitive.
The index of the instance whose bounding box to return.
The primitive’s purpose for which to return the bounding box maximum (e.g., “render”).
The maximum position of the instance’s bounding box.
// Get the max of the first instance's boundsng box. vector max = usd_pointinstance_getbbox_max(0, "/src/instanced_spheres", 0, "render");
