Z-Depth Composite

Usage  |  Controls

The Z-Depth Composite Node can be used to combine two depth maps together, using various different composition modes. The depth map from the first input is be combined with the depth map from the second input and passed down-stream.

Usage

Select a composition mode from the Mode menu. If a composite is only required over a limited number of frames, the in and out frames can be adjusted to specific the desired frame range.

Various composition modes are available:

Replace: Replace depth values from the first input with those from the second. If no depth value is available in the second input, the depth value from the first input will remain unchanged.

Nearer: Replace depth values from the first input with those from the second when the second input depth is nearer to the camera than the first input depth. If no depth value is available in the second input, the depth value from the first input will remain unchanged.

Further: Replace depth values from the first input with those from the second when the second input depth is further from the camera than the first input depth. If no depth value is available in the second input, the depth value from the first input will remain unchanged.

Controls

Composite

Mode: The composition mode used to combine the depth maps.

In-Frame: The first frame at which the composite will be applied. If the edit box is empty, the composite will be applied to all frames in the clip.

Out-Frame: The last frame at which the composite will be applied. If the edit box is empty, the composite will be applied to all frames in the clip.

Display

Viewer proxy: The resolution used to display the triangular meshes in 3D viewer windows. For high resolution images, selecting Half, Third or Quarter will increase rendering performance.

Transparency: The amount of transparency that is used to display a grey-scale depth map in the Cinema window.

Grey-scale gamma: The amount of gamma correction that is used to display a grey-scale depth map in the Cinema window.

Depth cut %: The difference in depth values (as a percentage of the distance between the near and far camera planes) at which triangular mesh edges will be cut when displaying the depth map in 3D viewer windows. Note that this option is for display purposes only and does not affect the depth map being passed down-stream from the node.

Show depth map: When enabled, a grey-scale depth map will be displayed in the Cinema window if one is available for the current frame.
