# nGL

3D graphics library for Ndless (and possibly other systems).

It's not a complete 3D engine, so there's no collision detection, animation etc.

Features

--------

- Fixed-function pipeline like OpenGL

- Matrix stack with custom size

- 3D transformations, like translation, rotation and scaling

- Perspective with custom FOV

- Depth buffer that can also be read from

- Fast blitting of TEXTUREs

- Fast sine and cosine using LUTs

- Safe and fast mode

- Texture mapping, with transparency
