In cgvR: Interactive 3D Visualization of Large Cayley Graphs via Vulkan

cgvR 0.1.2

• cgv_layout_fr() — Fruchterman-Reingold layout in 2D/3D (pure R).
• cgv_layout_fr_bh() — Barnes-Hut FR (O(n log n)) in C for large graphs.
• cgv_camera_mode() — switch camera mode (fly / orbit / arcball).
• cgv_fly_path() — animate camera along waypoints (Catmull-Rom spline).
• cgv_record_start() / cgv_record_stop() — video recording via ffmpeg pipe.
• cgv_is_stub_build() — TRUE when the package was installed without Vulkan / GLFW (stub build). Native APIs raise a clear error in that case.
• New configure flags --with-vulkan / --without-vulkan to force or skip the native rendering build (mirrors ggmlR's flag style).
• macOS support: configure auto-detects Darwin, sets OS_MACOS=1, picks Vulkan from VULKAN_SDK/macOS/, VULKAN_SDK/, or Homebrew (/opt/homebrew/lib, /usr/local/lib), and applies -mmacosx-version-min=12.0.

cgvR 0.1.1

• cgv_viewer() gains offscreen argument for headless mode.

cgvR 0.1.0

Initial development release.

• cgv_viewer(), cgv_close() — viewer creation and destruction.
• cgv_camera(), cgv_fly_to() — camera positioning and animation.
• cgv_set_graph() — load nodes, edges and 3D positions.
• cgv_set_visibility() — BFS visibility-zone control.
• cgv_highlight_path(), cgv_clear_path() — path highlighting.
• cgv_background() — background color.
• cgv_run() — render loop.
