Why GoGPU?

Inspired by this discussion on r/golang, we're building the GPU computing ecosystem that Go deserves — from low-level graphics to high-level GUI, all with zero CGO.

Ecosystem

Key Features

Feature Description
Zero CGO No C compiler required, simple go build
WebGPU API Modern, portable GPU abstraction
Smart Rasterizer 5 algorithms with per-path auto-selection (scanline, 4×4 tiles, 16×16 tiles, SDF, compute)
Dual Backend Pure Go (default) or Rust FFI (-tags rust) — same API, transparent choice
Layered Design Use only what you need
webgpu.h Compliant Binary-compatible with wgpu-native

Quick Start

package main

import (
    "github.com/gogpu/gogpu"
    "github.com/gogpu/gogpu/gmath"
)

func main() {
    app := gogpu.NewApp(gogpu.DefaultConfig().
        WithTitle("Hello GoGPU").
        WithSize(800, 600))

    app.OnDraw(func(dc *gogpu.Context) {
        dc.DrawTriangleColor(gmath.DarkGray)
    })

    app.Run()
}

Result: A window with a rendered triangle in ~20 lines of code.

gg + gogpu Integration

Use 2D graphics from gg directly in gogpu windows — with smart rasterizer auto-selection and GPU-direct rendering (zero CPU readback):

import (
    "github.com/gogpu/gg"
    "github.com/gogpu/gg/integration/ggcanvas"
)

canvas, _ := ggcanvas.New(app.GPUContextProvider(), 800, 600)

app.OnDraw(func(dc *gogpu.Context) {
    sv := dc.SurfaceView()
    sw, sh := dc.SurfaceSize()
    gg.SetAcceleratorSurfaceTarget(sv, sw, sh)

    canvas.Draw(func(cc *gg.Context) {
        cc.SetRGB(1, 0, 0)
        cc.DrawCircle(400, 300, 100)
        cc.Fill()
    })

    canvas.RenderDirect(sv, sw, sh) // GPU-direct, zero-copy
})
