This is a demo for par_camera_control.h, a one-file C library that enables orbit controls (a.k.a. tumble, arcball, trackball) or pan-and-zoom like Google Maps.

The native demo is easy to build on macOS. First make sure you have CMake and clang installed, then do make run. For other platforms, simply invoke CMake in the way that you normally do.

Notes

  • Ideas for par_camera_controller

    • Multi-touch support, especially for zoom.
    • Double-tap to focus.
    • First person mode (sketchfab has this).

  • Create par_camera_animator.h

    • Time-aware utility class.
    • Provides momentum for panning.
    • Sudden movements should be smoothed.
    • parca_grab_begin, parca_grab_end, parca_grab_begin, parca_zoom, parca_tick.
    • does not depend on par_camera_control, uses callbacks instead.

  • Demo ideas

    • Demonstrate precision crosshairs for deep zoom, similar to my old blog post.
    • Implement a view cube as seen in tinkercad. See ImGuizmo for inspiration.
