Method
This node generates a 2D mesh using the predefined structure of the geometry generated by the Face Tracker node: 68 vertices linked as triangles with texture coordinates. It takes as input a Face Tracker node, which is required for the node to render anything. When a Face Tracker node is linked the geometry is updated automatically each frame as long as the tracker has found and tracked a face.
The Face Tracking Geometry node allows the geometry produced by the face tracker to be rendered in different ways or multiple times easily with low overhead: the face tracking process is only done once using the Face Tracker. The Face Tracking Geometry node can also be used as input to other nodes which use geometry as part of processing, such as Particle Mesh Emitter, Clone to Mesh, Combine Geometry.
For more information on face tracking see the Face Tracker node.
