Draft
Conversation
- Accept Clang/AppleClang in CMake when EGE_BUILD_OPENGL=ON - Avoid stdint conflicts on Clang by gating bundled stdint and fixing __clang__ detection - Initialize graph state for GLFW backend and pump events to prevent startup segfault - Update PRD progress for macOS verification
…mitives - Define RenderTarget abstract interface (src/backend/interface/RenderTarget.h) covering 80+ drawing methods for full EGE API coverage - Implement GlRenderTarget (OpenGL 3.3 Core) with VBO+Shader batch rendering, FBO offscreen support, CPU/GPU sync, and basic primitives (line, rect, circle, ellipse, sector, arc, polygon, pixel) - Add GlShader utility for shader compilation/linking - Integrate GLAD 2.0 loader (OpenGL 3.3 Core profile, header-only) - Upgrade GLFWWindow to use GlRenderTarget instead of legacy immediate mode - Extend IMAGE class with m_renderTarget and m_glDirty fields - Wire screen RenderTarget to image pages in initgraph - Update egegapi.cpp drawing functions to route through RenderTarget - Suppress OpenGL deprecation warnings on macOS - Phase 3/4/5 stubs for image transfer, text rendering, and input Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- 实现 GlRenderTarget 图像传输方法：blit, blitStretch, alphaBlend, alphaTransparent, withAlpha, alphaFilter, rotateBlend, rotateZoomBlend, filterBlur - 实现 CPU ↔ GPU 同步：getPixelBuffer (GPU→CPU), syncToGpu (CPU→GPU) - 添加 ROP2 模式支持：XOR, AND, OR（shader 位运算 + destination texture 采样） - 实现 rebuild() 方法用于 resize 时重建 GPU 纹理 - 将 IMAGE::putimage 全系列函数路由到 RenderTarget（OpenGL 模式） - 新增 image blit shader（顶点变换 + 片段 ROP2 + color key + alpha override） Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
…/measureText Implement GlRenderTarget text rendering capability using stb_truetype: - Glyph atlas texture with on-demand rasterization (1024x1024) - setFont() with face, height, weight, italic, underline, strikeout support - setTextJustify() for horizontal/vertical alignment - drawText() for both char* (UTF-8) and wchar_t* strings - getTextWidth/Height and measureText for text measurement - Escapement/rotation support for rotated text - macOS system font path resolution (PingFang, Arial, etc.) - Text rendering demo (graph_text_opengl.cpp) Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
- Linux/macOS now default to EGE_BUILD_OPENGL=ON for true cross-platform support - mingw-w64 + wine cross-compilation deprecated with warnings - Updated BUILD.md to promote OpenGL as recommended approach - Legacy mode still available via -DEGE_BUILD_OPENGL=OFF
…port - Add captureScreenToTexture() to capture framebuffer before swapBuffers - Refactor submitBatch to create fresh VAO/VBO per batch (Core OpenGL compat) - Optimize getPixelBuffer for on-screen RT (skip GPU readback if not dirty) - Route all drawing functions in egegapi.cpp to m_renderTarget - Add OS event pumping in dealmessage for native GLFW backends - Implement getimage with OpenGL pixel readback (RT-to-RT blit + glReadPixels) - Fix macOS OpenGL context hints (retina framebuffer, doublebuffer) - Update demos to run 10 frames and save screenshots Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

What changed
Why
The previous build and runtime paths were coupled to Win32/GDI. Earlier cross-platform work could compile but did not prove pixel parity, camera lifecycle safety, or reliable process exit. The latest default-configuration test also reproduced two hidden CI gaps: an empty build type on fresh single-config builds and a Linux bundled GLFW default that required undocumented Wayland dependencies.
