Happy New Year, Gophers!

As 2025 drew to a close, I shared something that made me incredibly proud: Go is entering 2026 with its first professional graphics ecosystem.

Back then, it was 249,000 lines. Today — six weeks later — it's 380,000+ lines of Pure Go code and growing. A complete GPU computing stack that requires nothing but go build.

No CGO. No Rust. No C. Just Go.

Where We Are Now (February 2026)

The Numbers

The Ecosystem

What Changed Since January

A lot happened in six weeks. Here are the highlights.

GPU SDF Accelerator

The biggest architectural addition: hardware-accelerated shape rendering via Signed Distance Fields.

import _ "github.com/gogpu/gg/gpu" // opt-in GPU acceleration

dc := gg.NewContext(800, 600)
dc.DrawCircle(400, 300, 100)
dc.Fill() // GPU renders via SDF if available, CPU fallback otherwise

The accelerator auto-detects circles, ellipses, rectangles, and rounded rectangles from path data. Shapes that match get rendered via SDF compute shaders. Everything else falls back to the CPU rasterizer — transparently.

Architecture: CPU Core + GPU Accelerator

We made a fundamental architectural decision based on analysis of 8 enterprise 2D engines (Skia, Cairo, Vello, Blend2D, tiny-skia, piet, Qt RHI, Pathfinder):

CPU rasterization is the core. GPU is an optional accelerator.

In none of the 8 libraries analyzed is CPU rasterization a "backend". It's always the core. We follow the same pattern:

gg (2D Graphics)
  ├── internal/raster/   — CPU rasterization core (always available)
  ├── internal/gpu/      — GPU acceleration (uses wgpu HAL)
  └── gpu/               — Public opt-in: import _ "github.com/gogpu/gg/gpu"

• gg.Fill() tries GPU first, falls back to CPU
• ~17ns overhead when no GPU registered
• No "backend" abstraction in gg — GPU enhances, doesn't replace

Compute Shader Pipeline

Full GPU compute pipeline is now operational:

• naga compiles WGSL compute shaders to SPIR-V
• wgpu provides ReadBuffer HAL for GPU→CPU data transfer
• gogpu exposes HalProvider for sharing GPU devices across the ecosystem
• gg dispatches SDF compute work to the GPU

Shader Compiler Maturity (naga)

The shader compiler grew significantly:

• v0.8.3 → v0.12.0 (4 major releases in 6 weeks)
• Hex literal suffixes (0xFFu, 0x00i)
• SPIR-V validation fixes for compute shaders
• OpFunctionCall support
• Runtime array support for storage buffers
• 60+ WGSL built-in functions

WebGPU HAL Improvements (wgpu)

• v0.9.2 → v0.15.0 (6 major releases)
• ReadBuffer HAL abstraction — GPU buffer readback
• GPU Resource Leak Detection (zero overhead when disabled)
• W3C WebGPU Error Scopes (LIFO stack)
• Thread Safety Tests (concurrent access validation)
• Vulkan InitialLayout fix for LoadOpLoad render passes

Premultiplied Alpha Pipeline

Industry-standard premultiplied alpha compositing throughout the entire stack. Eliminates dark halos around anti-aliased shapes — matching what Skia, Cairo, and every professional engine does.

Unified Native Backend (gogpu)

The GPU framework eliminated ~950 lines of code duplication between Vulkan and Metal backends. A single implementation now works through the HAL abstraction layer:

• v0.9.2 → v0.17.0 (8 major releases)
• WindowProvider / PlatformProvider interfaces
• DPI awareness, clipboard, cursor management (Win32)
• HalProvider for GPU device sharing with gg

GUI Toolkit: Building, Not Just Designing

In January, we said gogpu/ui was "2026 Focus". Now it's 54,000 lines of code with 1,400+ tests.

What's Implemented

Architecture

The UI toolkit follows a three-layer architecture:

core/          — Widget implementations (button, checkbox, radio)
widget/        — Widget base system, lifecycle, context
theme/         — Material 3 theme system with tokens
state/         — Signals reactivity (Signal, Computed, Effect)
layout/        — Constraint-based layout (Flex, Grid, Stack)
focus/         — Keyboard navigation and focus management
event/         — Pointer, keyboard, IME events
render/        — Canvas abstraction over gg
a11y/          — Accessibility (planned: AccessKit)

Each widget is a separate package under core/ — promoting modularity and tree-shaking.

What's Next for UI

• Text Input — Cursor, selection, IME support
• Scroll Container — Virtualized list rendering
• Data Table — Sortable, filterable, virtualized
• Accessibility — AccessKit integration (Pure Go)

What's Working Right Now

Full Cross-Platform Support:

• Windows — Win32 windowing, Vulkan + DX12 + GLES backends, DPI awareness
• Linux X11 — Pure Go X11 protocol, Vulkan + GLES backends
• Linux Wayland — Pure Go Wayland protocol, Vulkan + GLES backends
• macOS — Cocoa windowing, Metal backend

Complete Shader Pipeline:

• WGSL source code
• Compiles to SPIR-V (Vulkan), MSL (Metal), GLSL (OpenGL), HLSL (DirectX)
• Vertex, fragment, and compute shaders
• 60+ built-in functions, atomics, barriers

GPU-Accelerated 2D Graphics:

• SDF accelerator for circles, rectangles, rounded rectangles
• Vello-inspired tile rasterizer (Sparse Strips)
• 29 blend modes (Porter-Duff + Advanced + HSL)
• Premultiplied alpha pipeline
• Layers, alpha masks, GPU text rendering
• PDF export backend (gg-pdf)

What's Coming: GPU Path Rendering

We just completed a deep research study of GPU path rendering across 8 libraries. The result: a three-tier GPU rendering architecture for gg.

The Problem

Our current GPU accelerator handles detected shapes (circles, rects) via SDF. Everything else falls back to CPU. For complex paths — bezier curves, concave polygons, paths with holes — we need GPU rendering too.

The Solution: Stencil-Then-Cover

The same algorithm used by Skia, Gio, femtovg, and NV_path_rendering:

Pass 1 (Stencil Fill):
  Fan triangles from path → GPU writes winding numbers to stencil buffer
  Two-sided stencil: front=IncrWrap, back=DecrWrap

Pass 2 (Cover):
  Bounding quad over path → read stencil → write color where stencil ≠ 0

Key insight: No complex CPU triangulation needed. Triangle fan from first vertex is O(n) and works for ANY path — concave, self-intersecting, with holes. The stencil buffer handles correctness.

Three-Tier Architecture

This is the next major milestone for gg.

The Community Effect

Here's what I love most about open source: we're not alone.

Active community engagement:

• @amortaza — Real-world testing with Rust and Pure Go backends, reporting critical findings (Discussion #47)
• @ppoage — macOS ARM64 testing (M1/M4), critical Issue #24 investigation, code contributions
• @Nickrocky — macOS Metal backend testing and feedback
• Community-reported issues leading to Vulkan fixes, NVIDIA compatibility improvements

Inspiration:

• u/m-unknown-2025 — The Reddit post that inspired GoGPU
• born-ml/born — ML framework where go-webgpu bindings originated

And if something still doesn't work? We fix it. Together.

2026 Roadmap — Updated

A Message to the Go Community

For years, the answer to "How do I do graphics in Go?" was:

"Just use Rust/C++."

That answer is no longer acceptable. Go deserves better.

With Go 1.26 and 380K+ lines of Pure Go graphics code, Go now has a GPU ecosystem that stands on its own.
