I am a newby of spatial computing and I am using ARKit and RealityKit to develop a visionPro app. I want to accomplish such a goal: If the user's hand touchs an object(an entity in RealityView) on the table, it will post a Window. But I do not know how to handle the event "the user's hand touchs the object". Should I use hand tracking feature to do some computing by myself? Or is there some api to use directly? Thank you!

I am a newby of spatial computing. Here I am learning how to use ARKit to capture the environment texture and apply it on a ModelEntity of RealityKit on Vision Pro. But I do not find a demo of how to use EnvironmentLightEstimationProvider. After checking the documentation, I also have some questions: EnvironmentProbeAnchor.environmentTexture is a MTLTexture, but EnvironmentResource needs a CGImage. How do I translate MTLTexture to CGImage(Forgive me that I do not know much about Metal or other framework, so It will be better if there is a code that I can copy and paste directly) It seems that the EnvironmentProbeAnchor can only get the light information around the device. But what should I do if I want get the light information around the ModelEntity so that I can apply the environment texture on it. It will be better if you can provide a code demo about how to use the new api. Thank you!

Hi folks, I’m new to Vision Pro stack, still trying to learn all the nuances. Here is a problem I can’t seem to find an answer. I placed entity A( a small .02 radius sphere) inside entity B( size:.1 box). Both entities have HoverEffectComponent, and both inputcomponent is set to .direct. Entity A is NOT a child of Entity B. When I direct touch Entity B, I noticed that Entity A’s hover effect is fired as well. This only happens if Entity A‘s position is inside Entity B. The gesture that is only targeted at Entity A doesn’t work either. I double checked Entity A collider which sits inside entity B collider, my direct touch shouldn’t have trigger its hove effect. Having one collider inside another seems to produce unpredictable behavior? Thanks in advance 🙏🙏🙏 Context: I’m trying to create an invisible bound around Entity A, so when my hand approaches the bound to grab Entity A, a nice spotlight hover effect would fire first on the bound before hand reaching entity A.

Hello, I was looking back into downloading the Tracking geographic locations in AR sample app from https://developer.apple.com/documentation/arkit/tracking-geographic-locations-in-ar Unfortunately the Download links to the .zip of the DisplayingAPointCloudUsingSceneDepth sample project. The exact same issue occurs when trying to download the sample code from https://developer.apple.com/documentation/ARKit/creating-a-fog-effect-using-scene-depth Wondering if those links are deliberately broken because of possible deprecations. Thanks to any Apple Engineer willing to look into that.
