matrix usd_pointinstancetransform(<stage>stage, string primpath, int index)
matrix usd_pointinstancetransform(<stage>stage, string primpath, int index, float timecode)
This function returns point instance transform.
<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.
index
The index of the instance within the point instancer.
timecode
The USD time code at which to evaluate the attribute. A USD time code roughly corresponds to a frame in Houdini. If not given, the time code corresponding to the current frame is used.
Returns
The transform of the point instance.
Examples ¶
// Get the transform of the third instance. matrix xform = usd_pointinstancetransform(0, "/src/instanced_cubes", 2);
