- Sep 14, 2026 Choosing a Mip Level from Screen-Space Derivatives How four partial derivatives become one level-of-detail value, why the maximum of the axes beats the average, and where trilinear blending and LOD bias change the answer. computer graphics
- Dec 17, 2025 Anisotropic Footprint Filtering Along the Major Axis Why a single mip level cannot represent an elongated pixel footprint, how an anisotropic sampler builds the ellipse, and where the extra taps go. computer graphics
- Apr 11, 2025 Ray Differentials for Texture Lookups Along a Ray How a pixel footprint propagates through reflection and refraction, why the propagated footprint can collapse or explode, and what to clamp when it does. computer graphics
- Aug 6, 2023 Quadric Error Metrics and What an Edge Collapse Actually Costs Each vertex accumulates the planes it can see as a 4x4 symmetric matrix; collapsing an edge sums two of them, and the result predicts geometric error without measuring it. computer graphics
