3D AOV Type option

Set the 3D AOV image segmentation type. Each type requires a specific AOV data pass, such as Distance requires a Z-depth map.

Active

Activate the image segmentation. Automatically turns on when you edit any of the Controls.

Create Map

Attach to the surface the map required by the 3D AOV Mode box, such as Z-depth for Distance, and set the map to the Analysis mode.

Controls - Range

Origin field

Sets where the segmented volume starts in the camera space.

Range field

Sets the depth of the segmented volume.

Gain field

Applies a gain to control the intensity of the output segmentation.

Falloff field

Controls the smoothness of the transition to and from the segmented volume.

Controls - Distance

Type option

Select the algorithm that decays the transition between the near and far clipping planes.

Amount field

Modulates the rate at which the transition decays for the chosen decay algorithm.

Gain field

Applies a gain to control the intensity of the output segmentation.

Controls - Near/Far

Near field

Sets the near clipping plane for the depth segmentation.

Far field

Sets the far clipping plane for the depth segmentation.

Applies a gain to control the intensity of the output segmentation.

Falloff field

Controls the smoothness of the transition to and from the segmented volume.

Controls - Normals

Direction field

Sets the direction of the incoming light.

Threshold field

Sets the range of the normals used to segment the image. Matches the dark area on the trackball.

Falloff field

Controls the smoothness of the transition to and from the segmentation.

Controls - Motion

The Motion mode requires access to Motion Vector data. The data can come from a Motion Vector texture map (if connected to the Surface) or from the Action Motion Vector output (if connected to the Camera). The Motion mode isolates part of the Motion data using direction and motion min/max fields, and then create a matte out of it.

Direction field

Controls what direction of the motion is included in the resulting matte.

Motion Min field

Filters out smaller motions from the selected direction the resulting matte.

Since the process of creating Motion Vector results includes a lot of small motion, you'll probably need to increase this value to get a precise motion segmentation result.

Motion Max field

Filters out the larger motions from the selected direction in the resulting matte.

Angular Threshold field

Defines the angle of the motion range included in the defined Direction.

Falloff field

Sets the shape of the curve that defines the motion range from the centre of the define direction and the limit of the Angular Threshold. While Linear interpolation is the default, increasing the Falloff creates a logarithmic-type interpolation.

Gain field

Applies a gain to control the intensity of the output segmentation.

Motion Vector widget

Controls the Direction and Motion Min settings.

Controls - Primitive

Use a primitive to precisely extract an object from the depth, something that cannot be done with other depth-based segmentation tools.
