The Geometry Normals Render Element uses screen space to determine the colors in the render element. With screen space in the camera view: The X axis runs left-right perpendicular to the camera viewing angle. This is represented in the Red channel of Geometry Normals with 1 being left-facing geometry and 0 being right-facing geometry. The Y runs up-down perpendicular to the viewing angle. This is represented in the Green channel of Geometry Normals with 1 being up-facing geometry and 0 being down-facing geometry. The Z runs forward-back to the viewing angle. This is represented in the Blue channel of Geometry Normals with 1 being forward-facing geometry and 0 being back-facing geometry. |
