Hello - I have been struggling to find a solution online and I hope you can help me timely. I have installed the latest tesnorflow and tensorflow-metal, I even went to install the ternsorflow-nightly.

The release notes for Xcode 14 mention a new AppleTextureConverter library. https://developer.apple.com/documentation/xcode-release-notes/xcode-14-release-notes TextureConverter 2.0 adds support for decompressing textures, advanced texture error metrics, and support for reading and writing KTX2 files. The new AppleTextureConverter library makes TextureConverter available for integration into third-party engines and tools. (82244472) Does anyone know how to include this library into a project and use it at runtime?

I'm developing a drawing app. I use MTKView to render the canvas. But for some reason and for only a few users, the pixels are not rendered correctly (pixels have different sizes), the majority of users have no problem with this. Here is my setup: Each pixel is rendered as 2 triangles MTKView's frame dimensions are always multiple of the canvas size (a 100x100 canvas will have the frame size of 100x100, 200x200, and so on) There is a grid to indicate pixels (it's an SwiftUI Path) which display correctly, and we can see that they don't align with the pixels). There is also a checkerboard pattern in the background rendered using another MTKView which lines up with the pixels but not the grid. Previously, I had a similar issue when my view's frame is not a multiple of the canvas size, but I fixed that with the setup above already. The issue worsens when the number of points representing a pixel of the canvas becomes smaller. E.g. a 100x100 canvas on a 100x100 view is worse than a 100x100 canvas on a 500x500 view The vertices have accurate coordinates, this is a rendering issue. As you can see in the picture, some pixels are bigger than others. I tried changing the contentScaleFactor to 1, 2, and 3 but none seems to solve the problem. My MTKView setup: clearColor = MTLClearColor(red: 0, green: 0, blue: 0, alpha: 0) delegate = renderer renderer.setup() isOpaque = false layer.magnificationFilter = .nearest layer.minificationFilter = .nearest Renderer's setup: let pipelineDescriptor = MTLRenderPipelineDescriptor() pipelineDescriptor.vertexFunction = vertexFunction pipelineDescriptor.fragmentFunction = fragmentFunction pipelineDescriptor.colorAttachments[0].pixelFormat = .bgra8Unorm pipelineState = try? device.makeRenderPipelineState(descriptor: pipelineDescriptor) Draw method of renderer: commandEncoder.setRenderPipelineState(pipelineState) commandEncoder.setVertexBuffer(vertexBuffer, offset: 0, index: 0) commandEncoder.setVertexBuffer(colorBuffer, offset: 0, index: 1) commandEncoder.drawIndexedPrimitives( type: .triangle, indexCount: indexCount, indexType: .uint32, indexBuffer: indexBuffer, indexBufferOffset: 0 ) commandEncoder.endEncoding() commandBuffer.present(drawable) commandBuffer.commit() Metal file: struct VertexOut { float4 position [[ position ]]; half4 color; }; vertex VertexOut frame_vertex(constant const float2* vertices [[ buffer(0) ]], constant const half4* colors [[ buffer(1) ]], uint v_id [[ vertex_id ]]) { VertexOut out; out.position = float4(vertices[v_id], 0, 1); out.color = colors[v_id / 4]; return out; } fragment half4 frame_fragment(VertexOut v [[ stage_in ]]) { half alpha = v.color.a; return half4(v.color.r * alpha, v.color.g * alpha, v.color.b * alpha, v.color.a); }

I've been object/mesh shaders using MTLRenderPipelineState built from MTLMeshRenderPipelineDescriptor with visible function tables. However, it seems that some functionality that is present on other MTL*RenderPipelineDescriptor types is missing. Namely, it lacks max<Stage>CallStackDepth() and setSupportAdding<Stage>BinaryFunctions(). The latter isn't too bad: I can always rebuild the the pipeline states from scratch if I want to add new linked functions. However, not being able to set the max call stack depth is limiting. I assume that means I only get a depth of 1 as that is the default value for the other descriptor types. In practice it seems that I can go up to 2 with the functions I'm using before I start getting kIOGPUCommandBufferCallbackErrorSubmissionsIgnored errors due to "prior/excessive GPU errors". I'm curious if the lack of this functionality on MTLMeshRenderPipelineDescriptor is a simple oversight. In my case I only am using VFTs and linked functions in the fragment stage. I suspect it should be possible since the other render pipeline descriptor types expose max call depths and adding binary functions in the fragment stage. FWIW I'm also using Metal-CPP (which is fantastic!) but I don't see this functionality in the Swift/Obj-C docs either.

Hi, i am developing a Metal renderer the Metal debbuger gives me an error when i try to debug a Fragment Shader. This is happening since i updated to sonoma and Xcode 15, before everything was working fine. Also i want to mention that i have tried the Apples DeferredLightning demo project and it gives the same error so its not my projects fault.

The Apple documentation seems to say RealityKit should obey the autoplay metadata, but it doesn't seem to work. Is the problem with my (hand coded) USDA files, the Swift, or something else? Thanks in advance. I can make the animations run with an explicit call to run, but what have I done wrong to get the one cube to autoplay? https://github.com/carlynorama/ExploreVisionPro_AnimationTests import SwiftUI import RealityKit import RealityKitContent struct ContentView: View { @State var enlarge = false var body: some View { VStack { //A ModelEntity, not expected to autoplay Model3D(named: "cube_purple_autoplay", bundle: realityKitContentBundle) //An Entity, actually expected this to autoplay RealityView { content in if let cube = try? await Entity(named: "cube_purple_autoplay", in: realityKitContentBundle) { print(cube.components) content.add(cube) } } //Scene has one cube that should auto play, one that should not. //Neither do, but both will start (as expected) with click. RealityView { content in // Add the initial RealityKit content if let scene = try? await Entity(named: "Scene", in: realityKitContentBundle) { content.add(scene) } } update: { content in // Update the RealityKit content when SwiftUI state changes if let scene = content.entities.first { if enlarge { for animation in scene.availableAnimations { scene.playAnimation(animation.repeat()) } } else { scene.stopAllAnimations() } let uniformScale: Float = enlarge ? 1.4 : 1.0 scene.transform.scale = [uniformScale, uniformScale, uniformScale] } } .gesture(TapGesture().targetedToAnyEntity().onEnded { _ in enlarge.toggle() }) VStack { Toggle("Enlarge RealityView Content", isOn: $enlarge) .toggleStyle(.button) }.padding().glassBackgroundEffect() } } } No autospin meta data #usda 1.0 ( defaultPrim = "transformAnimation" endTimeCode = 89 startTimeCode = 0 timeCodesPerSecond = 24 upAxis = "Y" ) def Xform "transformAnimation" () { def Scope "Geom" { def Xform "xform1" { float xformOp:rotateY.timeSamples = { ... } double3 xformOp:translate = (0, 0, 0) uniform token[] xformOpOrder = ["xformOp:translate", "xformOp:rotateY"] over "cube_1" ( prepend references = @./cube_base_with_purple_linked.usd@ ) { double3 xformOp:translate = (0, 0, 0) uniform token[] xformOpOrder = ["xformOp:translate"] } } With autoplay metadata #usda 1.0 ( defaultPrim = "autoAnimation" endTimeCode = 89 startTimeCode = 0 timeCodesPerSecond = 24 autoPlay = true playbackMode = "loop" upAxis = "Y" ) def Xform "autoAnimation" { def Scope "Geom" { def Xform "xform1" { float xformOp:rotateY.timeSamples = { ... } double3 xformOp:translate = (0, 0, 0) uniform token[] xformOpOrder = ["xformOp:translate", "xformOp:rotateY"] over "cube_1" ( prepend references = @./cube_base_with_purple_linked.usd@ ) { quatf xformOp:orient = (1, 0, 0, 0) float3 xformOp:scale = (2, 2, 2) double3 xformOp:translate = (0, 0, 0) uniform token[] xformOpOrder = ["xformOp:translate", "xformOp:orient", "xformOp:scale"] } } } }

How can I take the contents (i.e. the stroke and fill) of a CAShapeLayer and draw it into an MTLTexture, which can then be displayed with a normal vertex/fragment shader?

Hi there, I'm currently trying to install the game porting toolkit on my M2pro Mac Mini. (MacOS Sonoma 14.0) As the InstallAware AGPT-Installer always failed with "error 1" (..check disk space blabla) I tried the installation using the console and the steps described here: https://www.applegamingwiki.com/wiki/Game_Porting_Toolkit But: The general installation step always fails: brew -v install apple/apple/game-porting-toolkit It results in the following error: Error: apple/apple/game-porting-toolkit 1.0.4 did not build Logs: /Users/jgruen/Library/Logs/Homebrew/game-porting-toolkit/00.options.out /Users/jgruen/Library/Logs/Homebrew/game-porting-toolkit/wine64-build /Users/jgruen/Library/Logs/Homebrew/game-porting-toolkit/01.configure.cc /Users/jgruen/Library/Logs/Homebrew/game-porting-toolkit/01.configure If reporting this issue please do so to (not Homebrew/brew or Homebrew/homebrew-core): apple/apple If you scroll up, you can see the likely source of the problem: ... checking for ft2build.h... yes checking for -lfreetype... not found configure: error: FreeType 64-bit development files not found. Fonts will not be built. Use the --without-freetype option if you really want this. ... Note that I also have XCode 15.0 installed. FreeType is also available under /usr/local/opt/ All previous steps were ok. This one fails. How can I "install" the 64 bit development version? By the way I also have the include files, so some kind of FreeType dev code is here. (/usr/local/include/freetype2/ft2build.h for example) Any help or idea would be cool.

device: iphone 11 os: ios 15.6 I have a metal applicaton on IOS where a series of computer shaders are encoded, then disptached and comiited together at last. When I capture a GPU trace of my application, however I noticed there are these gaps between each computer shader invocation. And these gaps seem to take up a big part of the GPU time. I'm wondering what are these gaps and what are causing them. Since all compute dispatch commands are commiited toghether at once, these gaps shouldn't be synchronizations between cpu and GPU PS: In my application, later compute commands mostly depend on former ones and would use the result buffer from former invocations. But as shown in the picture, bandwith and read/write buffer limiter are not high as far as I'm concerned.

I can only download usdpython from following website: https://developer.apple.com/augmented-reality/tools/ And where could I get the various versions of the usdpython? Is the usdzconvert(usdpython) of Apple open source? Because I wanna learn how Apple achieves the conversion from GLTF to USDZ because I'm currently using version 0.66, and I feel that the conversion of GLTF features is not quite sufficient.

Creating an Entity and then changing between different animations (walk, run, jump, etc.) is pretty straightforward when you have individual USDZ files in your Xcode project, and then simply create an array of AnimationResource. However, I'm trying to do it via the new Reality Composer Pro app because the docs state it's much more efficient versus individual files, but I'm having a heck of a time figuring out how exactly to do it. Do you have one scene per USDZ file (does that erase any advantage over just loading individual files)? One scene with multiple entities? Something else all together? If I try one scene with multiple entities within it, when I try to change animation I always get "Cannot find a BindPoint for any bind path" logged in the console, and the animation never actually occurs. This is with the same files that animate perfectly when just creating an array of AnimationResource manually via individual/raw USDZ files. Anyone have any experience doing this?

I installed and configured all the environments follow the Read Me.rtf and then installed Steam with this command. gameportingtoolkit ~/my-game-prefix ~/Downloads/SteamSetup.exe. After installation, when I first opened steam.exe, it shows me this and installing update. It seems normal at this point. Then the window disappeared, and so is the steam icon in the dock. The terminal window is also unable to enter new commands. I don't know how to kill the steam.exe, so I just close this terminal window and open a new one. No matter how many times I tried with this, there is nothing happened. gameportingtoolkit ~/my-game-prefix 'C:\Program Files (x86)\Steam\steam.exe' If I try this command, MTL_HUD_ENABLED=1 WINEESYNC=1 WINEPREFIX=~/my-game-prefix $(brew --prefix game-porting-toolkit)/bin/wine64 'C:\Program Files (x86)\Steam\steam.exe' the steam icon will appears in the Dock but it always shows no available window. at the same time, too many logs come up and seem to never stop (I suspect they're duplicate messages form a certain location, but since I can't quiet understand what they are talking about, so I just copied some of them and put them in the attachment). I was wondering if it might have something to do with the error message when create the new Wine prefix, but this error message didn't seem to affect either the appearance of the “Wine configuration” window or the configuration. Anyone else having the same issues? I really don't know what went wrong. Thank you all for your patience in reading! part of log

Hello, I am writing a plugin for iOS for Unity. And recently the phone was updated, then I had to switch from xcode 14 to xcode 15, and now my plugin has stopped running with the error thread 1: EXC_BAD_ACCESS (code=1, address=0x0). But at the same time, there is no such error, if the project has appsflyer, one signal plugins at the same time, I can't find what exactly they can change, that there is no such problem. I have reviewed my entire project and the problem arises at this stage: [WebView loadRequest:request]; Just in case, I output data on delegates to the console and whether the wkwebview itself is empty, but no, everything is fine: 2023-10-26 13:42:10.239021+0300 WWebView[40416:4492528] request: <NSURLRequest: 0x282505d40> { URL: https://www.google.com/ } 2023-10-26 13:42:10.239052+0300 WWebView[40416:4492528] WebView.navigationDelegate != nil 2023-10-26 13:42:10.239074+0300 WWebView[40416:4492528] WebView.UIDelegate != nil Tell me, what could be the cause of such a problem?The plugin is written in objective-c, it worked before xcode 15, I can't check on the versions below, there is no device on which I could run xcode 14, since this version does not support new iOS versions.

I am experimenting with some alternative rendering techniques, where the scene is represented as a mixture of parametrised SDFs and the final shading is done evaluating and mixing the SDFs for each fragment. The basic algorithm divides the screen into tiles, collects and sorts the SDFs intersecting each tile, and then invokes the final compute shader. There can be multiple SDFs affecting each pixel as they are partially transparent. It seems to me that Apple's TBDR tile shading pipeline would be an ideal for for this type of algorithm, but I am not quite sure how to utilise it efficiently. Essentially, I was thinking about rendering bounding rects over the SDFs and leveraging the binning hardware to arrange them into tiles for me. What I need the rasterisation pipeline to spit out is simply the list of primitives per tile. But there is no "per-primitive-per-tile" shader stage, so this has to be done in the fragment shader. I could of course record the primitive ID per pixel, but this is complicated by the fact that I can have multiple primitives affecting each pixel. Plus, there will be a lot of duplicates, as there are usually not more than 5-6 primitives per tile, and sorting the duplicates out seems like a waste. What would be the most efficient way to handle this? Is there a way to utilize the tile shading pipeline to simply build out a list of primitive IDs in the tile?
