Hello everyone, I want to develop an app for vision pro that aims to help people with vertigo and dizziness problems. The problem is that I can not afford vision pro. If I use standart vr set with an iPhone inside would it cause issues on real vision pro?

Can someone explain the difference between MTLHazardTrackingModeTracked and MTLResourceHazardTrackingModeTracked please?

I init openGL now i wanna set glPixelZoom(pixelSizeX, -pixelSizeY); to dispaly a image with width and height to the entire window for this I do: rect:= window.frame; WindowBackingRect := window.convertRectToBacking(rect); pixelSizeX := WindowBackingRect.size.width / width / NSScreen.mainScreen.backingScaleFactor; pixelSizeY := WindowBackingRect.size.height / height / NSScreen.mainScreen.backingScaleFactor; under High Sierra 10.13.6 on an intel mac from 2011 NSScreen.mainScreen.backingScaleFactor return 1 because there is no retina. under Sonoma 14.3 an an intel mac from 2020 NSScreen.mainScreen.backingScaleFactor return 2 because of retina. this works correct. under Venture 13.6 on an aarch64 mac from 2020 NSScreen.mainScreen.backingScaleFactor returns 2 BUT the image is only half so big as it should be. (if i let the scale factor away on the new intel mac, the image is twice big as it should be. On the new AArch64 mac it is correct.) what to do?

Hi, I'm displaying linear gray by CAMetalLayer with the shader below. fragment float4 fragmentShader(VertexOut in [[stage_in]], texture2d<float, access::sample> BGRATexture [[ texture(0) ]]) { float color = in.texCoordinates.x; return float4(float3(color), 1.0); } And my CAMetalLayer has been set to linearSRGB. metalLayer.colorspace = CGColorSpace(name: CGColorSpace.linearSRGB) metalLayer.pixelFormat = .bgra8Unorm Why the display seem add gamma? Apparently the middle gray is 187 but not 128.

Please clarify if latest guides update allow to html5 games without binary inclusion. Does that mean that gambling apps do not required embedded resources for real money games in the app?

Hi, I am using metallib to generate shader cache shaders offline, but I have noticed that for certain .air files, metallib's behavior is unpredictable. Sometimes it runs correctly, sometimes it may crash or generate an invalid .lib file. // crash info 0x00007FF6705AA821 (0x000001C5F7218E30 0x00000084F9F8F089 0x000001C5F72B57E0 0x000001C5F7218E30) 0x00007FF6705A9062 (0x00007FF6709200E0 0x000001C5F7208CE0 0x0000000000000002 0x00007FF670920140) 0x00007FF6704C8FD6 (0x00007FF6709200E0 0x00007FF600000000 0x00007FF670920140 0x0000000000000000) 0x00007FF66FF7F1F4 (0x0000000000000000 0x000001C5F71EC210 0x000001C5F71EC210 0x0000000000000000) 0x00007FF66FF6C8D1 (0x0000000000000004 0x000001C5F71EC210 0x0000000000000000 0x0000000000000000) 0x00007FF670633974 (0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000) 0x00007FFB9C137614 (0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000), BaseThreadInitThunk() + 0x14 bytes(s) 0x00007FFB9DB826A1 (0x0000000000000000 0x0000000000000000 0x0000000000000000 0x0000000000000000), RtlUserThreadStart() + 0x21 bytes(s) I tried the latest version (Metal Tools for Windows 4.1), but the issue still exists.

Hi, I'm building a simple game for iOS. I have background music. The ring/silent switch is not disabling sound when switched to silent. So far I'm testing on devices through TestFlight (still internal testing, not beta). Do I need to code this function myself or does iOS know it's a game and disable sound automatically? and/or would my game be rejected if the switch doesn't disable sound? (I have an internal setting to enable/disable sounds in the game) Due to the way it's coded (capacitor app), I can't access the ring/silent switch to disable/enable sound. Thanks, this problem makes me feel like a preserved moose.

CGImageSourceCreateThumbnailAtIndex function isn't generating cgImage for majority of the images on iOS 17.4 OS version. It works if I pass in option kCGImageSourceThumbnailMaxPixelSize, but doesn't work if this key is missing. This function works with and without kCGImageSourceThumbnailMaxPixelSize in stable OS versions. Is this a new change in iOS 17.4 beta versions?

Seems that metal-shaderconverter can build a metallib, but I need .air files. Then I link the .air files into a single metallib and metallibdsym file. HLSL -> dxc -> DXIL -> metal-shaderconverter -> .metallib But there's no way to link together multiple metallib into a single metallib is there?

Hi there, I have some existing metal rendering / shader views that I would like to use to present stereoscopic content on the Vision Pro. Is there a metal shader function / variable that lets me know which eye we're currently rendering to inside my shader? Something like Unity's unity_StereoEyeIndex? I know RealityKit has GeometrySwitchCameraIndex, so I want something similar (but outside of a RealityKit context). Many thanks, Rich

Hi, I have a MBP 2023 M3 Max 64GB with 16 Core CPU ( 4 efficiency, 12 Performance) and 40C GPU. I've got a Game (Cities Skylines 2) successfully working using Whisky. However, only 4 Cores are reported to the game which leads to a situation where there are many calculations batched up while at the same time my CPU performance cores almost idle, while the efficiency cores are well utilized. I suspect this is because the game only sees 4 cores and has some logic to batch the calculations differently depending on how much cores are available. Is there a way to override how many cores the game sees? e.g. by using an environment variable or something? Thanks, Dominik

I captured my office using 3D Scanner and get a USDZ file. The file contains a 3-D Model and a Physically based material. I can view the file correctly with texture on Xcode and Reality Composer Pro. But when using RealityView to present the model in immersive space. I got the model in whole black. My guess is my Material doesn't have a shader graph? Does anyone caught into similar issue? How to solve it?

I’m really sorry if this is not the proper place for this. I’m developing a game with online mode what works just fine in WiFi mode but not in mobile network. If someone has two Apple devices and can try if with the mobile network the multiplayer mode works I will appreciate A LOT https://apps.apple.com/es/app/ufo-snowboard/id6474542185

I have build the plugins and added to project but when I run game I am getting these errors https://github.com/apple/unityplugins EntryPointNotFoundException: AppleCore_GetRuntimeEnvironment assembly: type: member:(null) Apple.Core.Availability.OnApplicationStart () (at Library/PackageCache/com.apple.unityplugin.core@d07a9d20344c/Runtime/Availability.cs:40) EntryPointNotFoundException: GKLocalPlayer_GetLocal assembly: type: member:(null)

As I understood, the ability to use metal is only in "vr" mode. But is there any way to make a custom post-process in mixed reality mode?

Hi, i am required to upload my CFD simulation results to the new vision pro glasses. This simulation shall be visible as a soft VR/AR object in the room. I am very new to the developer world. Could someone give me a hint which IDE, tool etc. to use for this task? SwiftUI, swift, visionOS, Xcode, ... ???? After I know what IDE/tool/language to use, I will start learning courses with it. Thanks a lot!!

Hi, I have a MacBook Pro with an Intel Iris Plus Graphics 640, which gives maximum 4.1 OpenGL context. Thus, I would like to use Mesa as an alternative for getting higher contexes e.g. 4.5 or 4.6. I don’t care about performance in this phase. I have built Mesa with LLVM (llvm-config… etc…) but even by placing the built libGL.dylib in the same folder with executable or setting DYLD_LIBRARY_PATH or DYLD_INSERT_LIBRARIES, I am not able to get the Mesa renderer. Does Apple support this overriding of libGL with a custom one? Any help/guidance would be really appreciated. Thanks

device.supportsRaytracing can be used to check if the device supports Raytracing. It seems most of the devices support Raytracing. However, only M3 and iPhone 15 Pro supports hardware Raytracing. How do I check programmatically if a device supports hardware Raytracing? Thank you.
