feat(webgl): Add WebGL GAL test infrastructure (Phase 1)
Add complete test infrastructure for WebGL GAL visual regression testing: - scripts/test-gal-regression.sh: Master script that builds both backends, runs tests, and performs two-level comparison (native vs baseline, webgl vs native) - scripts/build-gal-webgl-test.sh: WASM build using Makefile with em++ - tests/gal-regression/wasm/: WebGL test harness (stub WEBGL_GAL) - tests/e2e/gal-webgl.spec.ts: Playwright test for screenshot capture Fix Homebrew Emscripten environment in scripts/common/env.sh: - Set EMSDK_PYTHON for Python 3.10+ (em++ reads this, not $PYTHON) - Add bundled LLVM to PATH (Emscripten needs its clang with WASM backend) Verified: Native vs Baseline passes (28/28), WebGL generates blank screenshots as expected (WEBGL_GAL implementation is Phase 2). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

# WebGL GAL Port - Master Plan
|
||||
|
||||
## Goal
|
||||
Port KiCad's GAL (Graphics Abstraction Layer) from OpenGL to WebGL to enable full KiCad functionality in the browser. Use the existing 28-scenario test suite to verify visual parity between native OpenGL and WebGL implementations.
|
||||
|
||||
## Current State
|
||||
- **GAL Test Harness**: 28 scenarios covering 100% of GAL API (~70 methods)
|
||||
- **Native Test**: C++ binary using real OPENGL_GAL, outputs PNGs to `tests/gal-regression/baseline/`
|
||||
- **KiCad WASM**: Already runs in browser but crashes on OpenGL compatibility issues
|
||||
- **OpenGL GAL**: ~9,500 lines of C++/GLSL using mix of legacy GL and modern VBOs
|
||||
|
||||
## Key Decisions
|
||||
- **Approach**: Copy and modify existing OpenGL GAL code
|
||||
- **Scope**: Full feature parity (all 28 scenarios)
|
||||
- **Location**: Develop in `tests/gal-regression/` first, move to KiCad later
|
||||
|
||||
## Architecture
|
||||
|
||||
**Two-backend test architecture:**
|
||||
```
|
||||
┌─────────────────────────────────────────────────────────────┐
|
||||
│ SAME 28 SCENARIO FILES │
|
||||
│ (scenarios/*.cpp - pure GAL API calls) │
|
||||
└─────────────────────────────────────────────────────────────┘
|
||||
│
|
||||
┌───────────────┴───────────────┐
|
||||
▼ ▼
|
||||
┌─────────────────────────────┐ ┌─────────────────────────┐
|
||||
│ NATIVE TEST HARNESS │ │ WEBGL TEST HARNESS │
|
||||
│ (gal_native_test.cpp) │ │ (gal_webgl_test.cpp) │
|
||||
│ │ │ │
|
||||
│ Uses: OPENGL_GAL │ │ Uses: WEBGL_GAL │
|
||||
│ Runs: macOS native │ │ Runs: Browser/WASM │
|
||||
└─────────────────────────────┘ └─────────────────────────┘
|
||||
│ │
|
||||
▼ ▼
|
||||
┌─────────────────────────────┐ ┌─────────────────────────┐
|
||||
│ output/native/gal-*.png │ │ output/webgl/gal-*.png │
|
||||
└─────────────────────────────┘ └─────────────────────────┘
|
||||
```
|
||||
|
||||
## Master Test Script: `scripts/test-gal-regression.sh`
|
||||
|
||||
**This is the only script we run.** Single command to build, test, and compare everything:
|
||||
|
||||
```bash
|
||||
#!/bin/bash
|
||||
# Single script to build, run, and compare both backends
|
||||
|
||||
# 1. BUILD BOTH
|
||||
scripts/build-gal-native-test.sh
|
||||
scripts/build-gal-webgl-test.sh
|
||||
|
||||
# 2. RUN BOTH TESTS
|
||||
./tests/gal-regression/native/build/gal_native_test --output tests/gal-regression/output/native/
|
||||
npx playwright test gal-webgl.spec.ts # outputs to tests/gal-regression/output/webgl/
|
||||
|
||||
# 3. COMPARE (two-level)
|
||||
compare_screenshots output/native/ baseline/ # Catch native regressions
|
||||
compare_screenshots output/webgl/ output/native/ # Verify WebGL matches native
|
||||
|
||||
# 4. REPORT
|
||||
# Exit 0 if all match, exit 1 if any differ
|
||||
```
|
||||
|
||||
**Two-level comparison:**
|
||||
1. **native vs baseline** → Catches if native code regressed
|
||||
2. **webgl vs native** → Verifies WebGL implementation matches
|
||||
|
||||
**Output structure:**
|
||||
```
|
||||
tests/gal-regression/
|
||||
├── baseline/ # Committed reference screenshots
|
||||
├── output/
|
||||
│ ├── native/ # Fresh native run
|
||||
│ └── webgl/ # WebGL run via Playwright
|
||||
```
|
||||
|
||||
## Phases
|
||||
|
||||
### Phase 1: Master Test Script & WebGL Harness Infrastructure
|
||||
Create the unified test script and WASM-based test harness.
|
||||
|
||||
**Deliverables:**
|
||||
- [x] `scripts/test-gal-regression.sh` - Master build/test/compare script
|
||||
- [x] `tests/gal-regression/wasm/` directory structure
|
||||
- [x] `tests/gal-regression/wasm/Makefile` - Emscripten build (use Makefile, not CMake)
|
||||
- [x] `tests/gal-regression/wasm/gal_webgl_test.cpp` - WASM entry point
|
||||
- [x] `tests/gal-regression/wasm/gal_webgl_test.html` - Test page with canvas
|
||||
- [x] `scripts/build-gal-webgl-test.sh` - WASM build script (uses Makefile)
|
||||
- [x] `tests/e2e/gal-webgl.spec.ts` - Playwright spec for screenshots
|
||||
|
||||
**Build Approach:**
|
||||
- Use a Makefile with direct `em++` calls (like `tests/apps/Makefile.wasm`)
|
||||
- Avoid `emcmake cmake` which requires Python 3.10+ (system has 3.9.6)
|
||||
- Follow the same pattern as `build-wasm-test.sh`
|
||||
|
||||
**Verification:** Master script builds both, runs native successfully, WebGL loads empty page.
|
||||
|
||||
### Phase 2: WEBGL_GAL Implementation
|
||||
Copy and modify OpenGL GAL to create pure WebGL implementation.
|
||||
|
||||
**Approach:** Start with `kicad/common/gal/opengl/opengl_gal.cpp`, then:
|
||||
1. Replace legacy immediate mode (`glBegin/glEnd`) with VBO-based rendering
|
||||
2. Replace GL matrix stack with glm matrices (already used internally)
|
||||
3. Adapt shaders for WebGL 2.0 / GLSL ES 3.0
|
||||
4. Handle WebGL-specific limitations
|
||||
|
||||
**Key Files:**
|
||||
- [ ] `tests/gal-regression/wasm/webgl_gal.h` - Class declaration
|
||||
- [ ] `tests/gal-regression/wasm/webgl_gal.cpp` - Main implementation
|
||||
- [ ] `tests/gal-regression/wasm/webgl_shaders.cpp` - Shader sources
|
||||
- [ ] Adapt vertex_manager, gpu_manager as needed
|
||||
|
||||
**Verification:** Scenario 0 (basic-lines) renders, master script compares successfully.
|
||||
|
||||
### Phase 3: Complete API Coverage
|
||||
Implement all GAL methods to pass all 28 scenarios.
|
||||
|
||||
**Method Groups (incremental):**
|
||||
1. Basic drawing: DrawLine, DrawSegment, DrawCircle, DrawArc
|
||||
2. Shapes: DrawRectangle, DrawPolygon, DrawPolyline
|
||||
3. Advanced: DrawBezier, DrawBezierArc, DrawArcSegment, DrawSegmentChain
|
||||
4. State: Colors, transforms, depth testing, render targets
|
||||
5. Groups: BeginGroup, EndGroup, DrawGroup, ChangeGroupColor/Depth
|
||||
6. Text: DrawGlyph, DrawGlyphs, BitmapText
|
||||
7. Special: DrawGrid, DrawCursor, DrawBitmap
|
||||
|
||||
**Verification:** Run master script after each group - all implemented scenarios match.
|
||||
|
||||
### Phase 4: Integration with KiCad
|
||||
Move WEBGL_GAL into KiCad source and enable for browser builds.
|
||||
|
||||
**Deliverables:**
|
||||
- [ ] Move `webgl_gal.*` to `kicad/common/gal/webgl/`
|
||||
- [ ] CMake integration for Emscripten builds
|
||||
- [ ] Runtime GAL selection based on platform
|
||||
- [ ] KiCad WASM builds successfully with WEBGL_GAL
|
||||
|
||||
**Verification:** KiCad loads in browser, opens PCB, renders correctly.
