# #112 — 3D Rendering with Rotation and Projection

Back

Can I draw and rotate a 3D cube using Processing's 2D renderer with just some math?!?! Yes! Watch to learn more about rotation and projection matrices along with perspective and orthographic projection!

In this video, I introduce the idea of "Linear Algebra" and explore the matrix math required for a simple neural network library.

In this video, I write a function to perform matrix multiplication in Java.

In this Live Stream, I attempt to draw 3D shapes on a 2D canvas
