- Mar 30, 2026 Perspective-Correct Interpolation and the Reciprocal-W Trick Why screen-space linear interpolation of a clip-space attribute is wrong, how dividing by w before the rasterizer and dividing back after the vector unit restores correctness, and what it costs. gpu computing
- Mar 6, 2026 Histogram Buckets, the +Inf Bucket, and How Quantiles Are Interpolated Why histograms store counts per bucket rather than values, how cumulative bucket counts make merging trivial, and what linear interpolation inside a bucket assumes about the distribution. observability
- Feb 12, 2026 Scattered Data Interpolation and the Conditioning of Radial Basis Functions Why meshless reconstruction solves a dense linear system, how the kernel choice decides between smoothness and conditioning, and what local stencils recover at a fraction of the cost. scientific computing
- Sep 14, 2025 Polyphase Decimation and the Cost of Changing Sample Rate Why a naive resampler computes samples it discards, how the polyphase decomposition removes that work, and what the filter length must satisfy before downsampling. scientific computing
- Oct 27, 2024 Sample Positions, Trilinear Interpolation, and the Half-Cell Offset Why a scalar grid carries two coordinate conventions, what trilinear interpolation costs and how it errs, and how resampling a field to a second grid trades resolution against aliasing. scientific computing
