Applies texture coordinates to meshes via a camera projection. In Gaffer, texture coordinates (commonly referred to as UVs) are represented as primitive variables.
Container for user-defined plugs. Nodes should never make their own plugs here, so users are free to do as they wish.
The processed output scene.
The on/off state of the node. When it is off, the node outputs the input scene unchanged.
The input scene
The filter used to control which parts of the scene are processed. A Filter node should be connected here.
The location of the camera to use for the projection.
The name of the primitive variable used to store the projected UV coordinates. This may be changed to store multiple sets of UVs on a single mesh.
