I'd like to find out how the minecraft renderengine works and perhabs adapt it to other technologies. Is there an analysis of the seemingly quite simple render engine of minecraft?

Voxels, just orthogonal borders and some other constraints apply to this engine.

I'm pretty much new to speedrunning. I know nothing about it and just want someone to teach,so with that, what tips and words of advice could you have for someone like me? :)

and if anyone would take time to teach me, teach me:D

What strategies and techniques should I practice?

Thanks! :)
