# blockens-3d

Blockens-3d project to learn 3D GPU programming and 3D math using Metal



I learned about vertex and matrix math from several books and online resources but mostly from [3D Math Primer for Graphics and Game Development](https://www.amazon.com/Math-Primer-Graphics-Game-Development-ebook/dp/B008KZU548/)

## This project features:

 * Keyboard controls for controlling the 3D cube.

 * An orthographic projection

 * Translation, rotation transforms and model-view rendering. 

 * I learned about wind order and culling and how the order of vertices dictate which side of a shape is the front.

 * Stencil depth, and various other 3D related aspects.

## Controls:

* Rotation: W, A, S, D, F, B

* Zoom: + -

* Translation: Up, Down, Left, Right, O, I

* Manipulate the far point with [ and ]

* Manipulate the near point with < and >
