Metal Demo: Hit Test , Mouse Pick , Shadows

I am a hobbyist programmer and I have been fooling around with Metal. In getting my feet wet in metal I have found that there is a pretty big gap between the HelloTriangle and DeferredLighting sample code from Apple and a more intermediate sample would be helpful. I have stumbled along through the brush and put together a little app that I thought that other novice metal programmers might find interesting.

Features:

1. Vertex buffer creation in Object Space.

2. Composing objects into a scene in Model Space.

3. Transforming a scene in Model Space to Clip Space

4. Hit Testing / Mouse Picking

5. Two pass rendering to produce shadows.

I have put the project on GitHub for others to peruse:
