LerpIt

Interactive lessons on simulation, rendering, and animation.

The lerpette library

Lerpettes grouped by collections.

Collection

Physics engine

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

Physics engine

Simple dynamics

This lerpette starts with two of the smallest useful ideas in rigid body simulation: a force accumulating over time, and an impulse changing velocity immediately.

Rendering

Open collection

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

Rendering

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.
