To remove an image background from a semitransparent mask, you can use techniques involving alpha blending and color pipelines, as discussed in the session "Render Metal with passthrough in visionOS." In this session, it is explained that the visionOS color pipeline uses the pre-multiply alpha color convention. This means you multiply the color channel in your shaders by the alpha value before passing it to composite or services. This approach helps in combining textures realistically, which can be useful for handling semitransparent masks.
For more detailed information, you can refer to the session Render Metal with passthrough in visionOS (05:25).
