Demo Frustum is an educative tool to explain how 3d by tracking the observer works.

I started this mini project while doing slides when I realized how difficult it was to draw a correct-looking frustum…

The build system is using Cmake.

To build:

> mkdir build && cd build
> cmake ..
> make

Feel free to try other CMake generators as well...

To run:

• On linux:

    > ./demofrustum
  

• On OS X:

    > open Demo\ Frustum.app
  

  or simply double-click on the Demo Frustum application.
