Description

Freya Holmer's Acegikmo YouTube channel publishes visual math and shader content for game developers. Holmer is known for creating Shader Forge (pre-Unity Shader Graph), the Shapes vector-graphics Unity plugin, and past work including the VR title Budget Cuts.

The Math for Game Devs 2022 lecture series spans vectors, dot and cross products, matrices, trigonometry, interpolation, trajectories, derivatives, abstract algebra, splines, and procedural animation across ten multi-hour parts with assignment walkthroughs. Separate videos cover shader coding, blending, easing, and framerate-independent lerp smoothing.

Presentation emphasizes geometric intuition with live Unity or whiteboard demos rather than symbol-heavy proofs. Content suits developers who want to understand transforms, splines, and shader math before writing HLSL.

All videos are free on YouTube. Talks such as Lerp Smoothing Is Broken distill blog-length math investigations into conference-style recordings.

Widely linked in graphics learning lists alongside 3Blue1Brown for game-specific math; especially popular among Unity developers seeking clear explanations of vectors, easing, and shader fundamentals.
