Gets the height of the color map the camera rendered most recently, in texels, or 0 when the camera has not rendered one. See SceneColorMapHandle#width.
Gets the width of the color map the camera rendered most recently, in texels, or 0 when the camera has not rendered one. A compute shader processing each texel of the color map is dispatched over this size, see Compute#setupDispatchThreads. It changes with the color map, so read it right before the dispatch: once the camera renders in the frame, it is the width of the color map of this frame, and before that, of the previous frame.
A handle to the scene color map of a camera, obtained from CameraComponent#sceneColorMapHandle. The handle is a single object for the lifetime of the camera, and always identifies the color map the camera rendered most recently, together with how it is encoded, even as the camera renders it to a different texture.
Pass the handle to Compute#setSceneColorMap to make the color map available to a compute shader.
