Luminance From Depth
Method #
Generates a greyscale luminance image from a depth source, usually a Depth Camera / Kinect Source or a Colour And Depth Source node.
Parameters
These properties control the core behaviours of the node.
Parameter Details Preview In Viewport
Preview the generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
- PIP : Preview the image blended with alpha in the viewport, in a smaller picture in picture display, on top of the existing content.
Apply PostFX Before Alpha Image Input (Legacy)
When enabled, the alpha input image is applied after the postfx pass, overwriting any effects the postfx would have applied to the alpha channel.
Near Plane
The near clip plane. Depth values less than this are masked out.
Far Plane
The far clip plane. Depth values greater than this are masked out.
Falloff
Control the falloff of the output image.
Invert
Invert the value output for the depth image.
Depth Range
What range of depth to use.
- Kinect v1 : Use the depth range of the Kinect v1.
- Kinect v2 : Use the depth range of the Kinect v2.
- RAW Depth : Use the raw depth data.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
