v0.1.0 - gpgpu MVP 🎉

gpgpu is a GPGPU compute framework built on top of wgpu compute pipeline. It tries to be simple to use whilst being easy to integrate with wgpu.

✨ Features

🔖 GPU Compute made simple

gpgpu exposes some GPU objects with clearly defined methods for read and write data from / to the GPU. Some of these objects are:

• GpuBuffer: Homogeneous read-write (in shaders) buffer on the GPU.
• GpuUniformBuffer: Homogeneous read-only (in shaders) buffer on the GPU. Perfect for small, readonly data.
• GpuConstImage and GpuImage: 2D homogeneous image on the GPU. The former is read-only, while the latter is write-only (in shaders).

gpgpu also exposes DescriptorSet and Kernel objects to make easier the management and reuse of binding groups and executions of shaders.

🚩 integrate-image feature for integration with image crate

• Compile-time type conversion safety from/to image::ImageBuffer to/from gpgpu::GpuImage and gpgpu::GpuConsyImageobjects
  • Supported pixel types:
    • RGBA8 Uint
    • RGBA8 Uint Norm
    • RGBA8 Sint
    • RGBA8 Sint Norm
  • Bidirectional conversions between image::ImageBuffer and gpgpu::GpuImage or gpgpu::GpuConsyImage
    • Sync and async read
    • Sync and async writes

⛰ Enviroment backend selection

Using the env variable WGPU_BACKEND, the gpgpu-rs backend can be selected. Available options are:

• Vulkan: "vulkan" or "vk"
• DX12: "dx12" or "d3d12"
• DX11: "dx11" or "d3d11"
• Metal: "metal" or "mtl"
• OpenGL ES: "opengl", "gles" or "gl"
• WebGPU: "webgpu"
  Any comma separeted combiantion of any of the previous options is valid. ex. WGPU_BACKEND='vk,gl'

🆘 Help wanted

• For an efficient implementation of the conversion between image and gpgpu types, some unsafe code was required. A review of this fragment is very much appreciated 😄 (in src/features/integrate_image.rs 👀).
• I'm running out of ideas. The initial goal of this project was to allow me develop a GPU-based image processing library (imageproc_gpu). Since I think gpgpu is enough for that (but still very lacking), I'll continue with that project, adding whatever I need for GPGPU computing back at gpgpu. Any other idea is appreciated.
