primitives_gallery

Catalogo visual de las primitivas y componentes ImGui del registry. Cada demo se carga al hacer click en su entrada del sidebar.

Build & run

cd cpp && cmake --build build --target primitives_gallery -j
./build/primitives_gallery

Modo capture (regresion visual)

./build/primitives_gallery --capture <out_dir>

Renderiza cada demo offscreen y guarda PNGs en <out_dir>/. Permite gate visual via golden images.

Notas

• auto_dockspace = false — usa fullscreen_window que ocupa todo el viewport.
• init_gl_loader = true — necesario para demos de OpenGL 4.3 core (compute, SSBOs).
