vector usd_getbbox_center(<stage>stage, string primpath, string purpose)
Computes the center of the bounding box for the 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".
The path to the primitive.
The primitive’s purpose for which to return the bounding box center (e.g., "render").
The center of the primitive’s bounding box.
// Get the center of the sphere's bounding box. vector center = usd_getbbox_center(0, "/src/sphere", "render");
