[SWIFT SHADER 2.1 .rar
Oludare Padilla
I'm trying to make my own shader to use as an SKShader for an SKSpriteNode, but I just don't know the proper way to do it. All I want is a way to write the shader code with autocompletion and to see the shader without having to wait ages for some huge program to compile it, but it seems to be more difficult than I thought.
I've already installed GLFW3 and a couple of other odd things since most tutorials suggest something like this for using OpenGL, but it seems to be more for OpenGL as a whole, rather than just one specific kind of shader.
Editing the shader source should update the live preview, but there seem to be at least some Xcode versions where you have to re-select the custom shader in the inspector for changes to take effect. (That's probably also worth filing a bug on...)
A working spritekit shader that is very very simple can be found at my blog post on the subject. You should work from an existing example instead of starting from scratch. A number of useful links to shader info are included.
There are other stuff out there as well. While autocomplete will help, there are plenty of other ways to have compilation issues. Just like normal coding through Xcode for ObjC/Swift .. you have have correctly auto-completed code. But it still can break. You're far better off exerting energy coming up with an optimized path to get out errors and to test your shader.
keep in mind, you're not going to be programming shaders all the time. These tend to be few and far between in the course of building a game (assuming you're doing a game, so if not, then this statement may have no validity).
I've always worked with Xcode projects but now I'm starting a project that I want in the future run on other platforms, so I'm using Swift Package Manager to generate the project, but I'm facing an issue, my library need to include a metal shader file (also a openGL shader file), but I'm clueless on how to accomplish this.
My project has 2 parts, the library that holds the graphic stuff and the executable that is my actual application, so I want to import my graphic library into my application, but the issue is that the metal shader file is not included in the Xcode project also seems that isn't compiled/included in the bundled files for the library so I can load at runtime and use it when needed.
The file MetalShaders.metal should contain the Metal source code, and the file MetalShaders.swift should contain the necessary setup code. One example for initial content of MetalShaders.swift is the following:
With this approach, the packageMetalLibrary variable can then be accessed from the Xcode project that has a dependency on the Swift Package by importing the target from the swift package the same way that other frameworks or packages are imported.
It may be possible to use this approach with earlier versions of Xcode as the method MTLDevice.makeDefaultLibrary(bundle:) is available since iOS 10 / macOS 10.12, but the Bundle.module extension would need to be implemented and it is not clear if this will work.
Edit: a temporary solution that I found was create an bash script that edit the workspace settings to change the build path and then compile/copy the metallib file to the executable path (didn't tried yet to see how to work distributing the library through SPM or something like that, right now only works with the code in the same folder (i.e. Sources/MyEngine
I have seen many examples where a texture buffer is read and written to in a compute shader, but I need to read and modify the vertex buffer, which contains custom vertex structs with normals, and is created by a MDLMesh. I would be forever grateful for some sample code!
What I actually want to achieve is really to be able to modify the vertex normals on the GPU. The other option would be if I could access the entire triangle from the vertex shader, like in the linked answer. For some reason I can only access a single vertex, using the stage_in attribute. Using the entire buffer does not work for me in this particular case, this is probably related to using a mesh provided by Model I/O and MDLMesh. When I create the vertices manually I am able to access the vertex buffer array. Having said that, with that solution I would have to calculate the new vertex normal vector three time for each triangle which seems wasteful, and in any case I want to be able to apply compute shaders to the vertex buffer!
Visual Studio
To build the Vulkan ICD library, use Visual Studio 2019 to open the project folder and wait for it to run CMake. Open the CMake Targets View in the Solution Explorer and select the vk_swiftshader project to build it.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
All changes require a Change-ID tag in the commit message. A commit hook may be used to add this tag automatically, and can be found at: -review.googlesource.com/tools/hooks/commit-msg. You can execute git clone and manually place the commit hook in SwiftShader/.git/hooks/, or to clone the repository and install the commit hook in one go:
Some tests will automatically be run against the change. Notably, presubmit.sh verifies the change has been formatted using clang-format 11.0.1. Most IDEs come with clang-format support, but may require upgrading/downgrading to the clang-format version 11.0.0 release version (notably Chromium's buildtools has a clang-format binary which can be an in-between revision which produces different formatting results).
googletest contains the Google Test project, as a Git submodule. It is used for running unit tests for Chromium, and Reactor unit tests. Run git submodule update --init to obtain/update the code. Any contributions should be made upstream.

I'd also thought that due to having a few devs and the fact that it was used instead of mesa by google for lots of things that llvmpipe would be slower since it hasn't really gotten dedicated development resources.
I guess the swift is just good marketing name, now I'm not sure why llvmpipe/lavapipe isn't more of a development target for those devs, imagine how much better it could be if it has fulltime dedicate devs on it.
It runs rendering tests almost correctly; the only minor bugs seem to be somewhere in attenuation of fixed function vertex lights. Everything else, including shaders, shadows, render to texture works without any problems.
I don t know what version is on my notebook because of this I detailed all the components on it ,probably is intel hd graphics 2000 or 3000, please tell me if it supports pixel shader 3 this model or if they are new drivers to improve the performance for this model.I want to know what games can I play with this laptop and if it is a list made for my model processor.I want to know if I can play Counter Strike Global Offensive, Call of Duty: Modern Warfare 2 and 3, Battlefield: Bad Company, Street Fighter IV and others.
I have downloaded the latest drivers for intel hd graphics i3 version 8.15.10.2993 but shaders 3.0 aren't still supported. I checked it by GPU caps viewer and it shows that supported just 2.0 not over
glclal, I am sorry about the trouble, I have confirmed through engineering that once you install the latest video drivers, shader model is available with version 4, please take a look at some specifications here:
Ol boa tarde! Algum poderia me ajudar? Estava fuando os programas pelo painel de controle do note para desinstalar algum programa que possvelmente estivesse muito pesado e acabei desinstalando o gpu shader 3.0. Agora meu jogo Pes 2012 no roda mais. Como posso reinstalar este programa?

The number of features and unique things that make this special are numerous, but it's far easier and more interesting for you to see how intuitive it is by checking out some examples.
A suit of examples are available at GateEngineDemos. This suite is developed and expanded in parallel with the GateEngine main branch.
I have no knowledge of how game engines work, so sorry if I'm asking a dumb question, but how does the multiplatform rendering work? Does the engine have automatic mappings to DirectX on Windows and, I'm not sure, Metal on macOS/iOS?
Android support is currently delayed because I simply can't afford to buy any major android device right now. GateEngine's platform support is hand written to use native UI code to create an experience users expect on each platform. So it's important to me that I understand the platform before creating a backend.
It's possible the Linux support will work for Android, but true native Android support is coming.
Users can visualize performance issues in their own projects by adding the PerformanceRenderingSystem to their game.
It's barebones currently, but will draw an overlay with helpful performance information.

Yes. Extensive documentation, tutorials, etc... but not until v1.0.0. is done. The API is still volatile so I don't want to spend too much time making instructions just yet. That's why I opted for GateEngineDemos for now, I can quickly fix and update them by just building them.
