Example Offset Node

This is an example OmniGraph node. It adds a fixed offset specified by the ‘offset’ input attribute to any attributes within the input bundle ‘geometry’ that have type ‘float[3]’ and appends these points to the output ‘points’ array. The offset is ignored if the input ‘disable’ is set to True. This gives a rough guideline of how to access some of the most common data types. See the online OmniGraph documentation for more detail on what you are able to do within a node.

Installation

To use this Node, you must enable omni.example.cpp.omnigraph_node in the Extension Manager.

Inputs

Name	Type	Description	Default
Disable Offsets (disable)	bool	Set this to false to prevent any offset from being applied to points	True
Offset Amount (offset)	float[3], float	Amount of offset to be applied to all of the values in the ‘points’ bundled attribute. If the attribute value is resolved to be a float[3] then that value is applied evenly to every point. If the attribute value is resolved to be a plain float then that value is used as a common offset for each of the x, y, and z components of the points.
Geometry To Offset (geometry)	bundle	A bundle is a collection of attributes with their own names. This node inspects the bundle to find attributes of type ‘float[3]’. If found then it extracts each member, adds the offset to them, and appends the results to the output ‘points’ array attribute.

Outputs

Name	Type	Description	Default
Offset Points (points)	float[3][]	Set of points extracted from the input ‘geometry’ bundle with the offsets added. If there is no matching attribute in the geometry bundle then this will be an empty array.
