- Sep 13, 2026 Mip Chain Construction by Box Reduction What averaging four texels into one actually preserves, where the filter sits against the ideal low-pass, and why sRGB, normal maps, and odd dimensions each need different treatment. computer graphics
- Mar 7, 2025 Why Blending in Gamma-Encoded Space Produces Wrong Colours What the display transfer function does to a weighted average of two colours, why source-over compositing belongs in linear light, and where the correction sits in a renderer. computer graphics
- Oct 17, 2023 Computing Relative Luminance and Contrast Ratios from sRGB Values The linearisation step, the weighted sum behind relative luminance, and why the WCAG ratio adds a constant to both values before dividing them. accessibility
- Apr 10, 2023 The sRGB Transfer Function: Piecewise Curve, Constants, and Decode Cost How the sRGB encoding is defined, why it bends into a straight line near black, and what the exact thresholds cost in a shader or a texture lookup table. computer graphics
