It's tiny 3D engine use scaneline algorithm, this way is capalble to calcualte flat shading, lighting and z buffer algorithm too, using only 4 * 320 byte as a buffer ( line buffer).
It can render full 320x240 pixel 16 bit deep frame, with using stm32 mcu which has only 20 KBram.
Now, it uses float point numbers, in the feauture I plan to use fix point numbers. In this case it could be a little bit faster.
