I’m implementing a "glow" impact in RealityKit. I adopted this open supply library which is in SceneKit: https://github.com/laanlabs/SCNTechniqueGlow. The fundamental concept is to create a "masks" texture that features all of the nodes that we wish to "glow", then do a gaussian blur (in each horizontal and vertical path) of the masks, then mix the blurred masks and the unique texture to create the impact.
I used to be in a position to replicate the identical lead to RealityKit. Nevertheless, I’m not certain learn how to apply the "glow" to solely chosen entities (For instance, solely these entities with a GlowComponent). In SceneKit, this may be simply carried out by includeCategoryMask, as documented right here: https://developer.apple.com/documentation/scenekit/scntechnique. There does not appear to be comparable API in RealityKit.
I’ve uploaded a pattern challenge right here: https://drive.google.com/file/d/1_VjhjSUzDplmhwiv2zmdclFUi6jevACC/view?usp=sharing
While you run it, you may see 2 views (screenshot): the highest view is a SCNView that makes use of the SCNTechnique; the underside view is a ARView that makes use of postprocess to attain the identical impact. Proper now I apply the impact to all entities. Nevertheless, I would prefer to solely apply it to these with GlowComponent
