Compositing Planes are special Pixotope actors, that are used to place video inside the virtual environment. They consist of a specialized geometry that enables the
TrackedCamera to project the video onto a specific depth in the scene. This allows for correct occlusions. Using a custom PostProcessing rendering pipeline we are able to avoid any video distortion like anti-aliasing and provide “pixel perfect” video.
For AR: Compositing planes can be used for AR reflections from the video onto the scene.
Although it is called "Compositing Plane", you can easily change the underlying geometry in the "Details" panel.
The Compositing plane allows integrating video with the virtual scene.
It is visible in reflections
It can cast shadows (Enable Cast Shadows in the Details panel)
It can receive shadows (Pixotope World Settings > VS > Cast Shadows On VS Plane)
It can be lighted up from scene lights (Pixotope World Settings > VS > Light Up VS Plane)
Mask out video
To mask out parts of the video you can use a plane or any mesh with a "feather pass" material.
Add a plane or any mesh acting as a garbage matte plane
Create a new material
Set the blend mode to Translucent
Enable "Render in Pixotope Feather Pass"
Assign this material to the plane via its Details panel
Disable the following options under Rendering > Advanced
Render in Main Pass
Render in Depth Pass
Render CustomDepth Pass
To make it work with Cast shadow on VS or Light up VS plane enabled also do the following:
On the VS Internal Compositing Plane
Set Feather Near to 1
Set Feather Far to 1
The Compositing Plane allows per plane feathering of the video.
Enable Plane rotation with the TrackedCamera (Details > Rotate with Camera).
Use body pose estimation for position
Uses the position of the BPE Compositing Mesh.
