Series: Building Go's GPU Ecosystem
— The journey
— Compute pipelines
— gg architecture
: unified 2D/3D graphics integration through standardized interfaces. This release enables seamless rendering of 2D graphics (viagg) into GPU-accelerated windows (viagogpu) — all in Pure Go, without CGO.
This is the foundation for
gogpu/ui, our upcoming enterprise-grade GUI toolkit.
The Problem We Solved
Modern applications need both 2D and 3D graphics:
UI elements (text, buttons, icons) require 2D rendering
Visualization (charts, graphs, CAD) requires GPU acceleration
Games and simulations require both
Traditionally, integrating these required:
- CGO bindings to native libraries (Cairo, Skia, Qt)
- Complex texture management between CPU and GPU
- Tight coupling between graphics and windowing code
We solved this with interface-based architecture — a pattern proven in enterprise systems.

The key insight: shared interfaces enable integration without coupling.
The TextureDrawer Interface
At the heart of our integration is
gpucontext.TextureDrawer:
CODE// gpucontext/texture.go
// TextureDrawer provides texture drawing capabilities for 2D rendering.
// This interface enables packages like ggcanvas to draw textures without
// depending directly on gogpu, following the Dependency Inversion Principle.
type TextureDrawer interface {
// DrawTexture draws a texture at the specified position.
DrawTexture(tex Texture, x, y float32) error
// TextureCreator returns the texture creator associated with this drawer.
TextureCreator() TextureCreator
}
// TextureCreator provides texture creation from raw pixel data.
type TextureCreator interface {
// NewTextureFromRGBA creates a texture from RGBA pixel data.
NewTextureFromRGBA(width, height int, data []byte) (Texture, error)
}
This interface follows the Dependency Inversion Principle:
ggdepends on abstractions (gpucontext.TextureDrawer)
gogpuimplements abstractions (Context.AsTextureDrawer())
- Neither depends on the other
