Description

Freya Holmér's October 2019 X thread catalogued here teaches lerp, inverse lerp, and remap as the three-step toolkit behind many shader and gameplay remappings, using compact formulas and animated examples rather than a formal article.

Lerp linearly blends between endpoints a and b with weight t; inverse lerp recovers t for a value between a and b; remap chains both operations to move a sample from an input range to an output range, matching the thread title and her later Mathfs utilities.

Intermediate programmers and technical artists who already touch vectors in Unity, HLSL, or node tools but want intuition before smoothstep or material-driven remaps are the target audience.

The resource is a free public social thread; related Math for Game Devs videos and community gist notes often point beginners to this specific status link as a quick refresher.

Holmér's interpolation threads are widely bookmarked in game-development circles for explaining inverse lerp before remaps, health-bar color grading, and driven material parameters.
