Why LerpIt?

Incremental learning in small chunks is easier and faster than taking a few big leaps.

We start by building a rigid body physics engine, going over integrators, collisions detection + resolution and constraints. We will then build a GPU version of the rigid body simulator.

Simple body dynamics

This lerpette starts with two of the smallest useful ideas in rigid body simulation:

Rendering

Open collection

This collection is for rendering lerpettes: depth, visibility, shading passes, and debugging views reduced to diagrams and compact runtimes.

Shadow maps

This lerpette treats a shadow map as a two-step story: first build a depth view from the light, then filter or sample that depth when shading from the camera.
