3D Blur Node

The 3D Blur node uses Z-depth map information to create a plausible blur effect. The node accepts a front, back, and matte input. Additional inputs are available for Z-depth map, motion data, and kernel media.

The 3D Blur node can be used as:

A defocus node, that can be modulated by a Z-depth map.
An artistic blur node, by modifying the pattern of the highlights. This can be done by editing the pattern profile curve or attaching an external clip to the appropriate node input.
A motion blur node, by including forward motion data.
A node using a combination of these scenarios.

The following table describes a general workflow for the 3D Blur node.

Step:	Refer to:
1. Apply a lens blur to the image.	See Creating a Lens Blur.
2. Determine the shape of the blur.	See Changing the Blur Pattern.
3. Apply depth of field effects to the image.	See Simulating a Depth of Field Effect.
4. Apply motion blur effects to the image.	See Simulating a Motion Blur Effect.
