CopyBBox for deep image stream
Smoothing the harsh holdout intersection that occurs when the holdout itself doesn't have enough samples.
It's a short-cup gizmo to convert quickly a multichannel layer into a deep image stream by normalising the 'distance form camera' channel output by your 3D render software.
Use ZDepth channel to make the Deep image.
Offset Deep data
keymix for deep
DeepSlice use the deep channel to select a slice out of the input image.
Soften or filter deep image by similar matrix method.
DeepBoolean works like maya's boolean's tool, but for deep in nuke. It works like deepHoldout but more function than that. Intersect mode to keep the deep data inside the geo matte. Subtract mode to holdout the deep data outside of the geo matte. Both support geo matte extrude (erode the terms in nuke) and falloff in 3D space.
