README

        
This is a demo for [par_camera_control.h](https://github.com/prideout/par),

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.
