- optimized rendering without local framebuffer, in STM32 case 1 to 32 lines buffer can be used
- pattern based background
- 3D starfield
- no floating point arithmetic
- no slow trigonometric functions
- rotations around X and Y axes
- simple outside screen culling
- rasterizer working for all convex polygons
- backface culling
- visible faces sorting by Z axis
- Tested with stm32duino and Arduino IDE 1.6.5
