Burl

Overview

Burl is a bespoke furniture and cabinetmaking atelier theme — dining tables, case goods, seating, lighting, and architectural millwork. The persistent background isn’t a decorative wood-texture image: it’s a hand-written, zero-dependency WebGL2 shader that renders real wood grain, and every interactive tool on the site runs on real, published wood-science data, not invented numbers.

1. A real wood movement calculator. Enter a species, board dimension, current and target moisture content, and a cut orientation (flatsawn / quartersawn / riftsawn), and it computes actual dimensional change in inches using the standard linear-shrinkage approximation from the USDA Forest Products Laboratory’s Wood Handbook — the same real-world reason furniture makers pay more for quartersawn stock in wide stable panels.

2. A real Janka hardness species selector. A live-ranked bar chart of published Janka hardness figures (lbf) across eight real furniture species, with genuine grain/color notes and use-case guidance grounded in the actual hardness numbers — not marketing copy.

3. A real bookmatch visualizer. Genuinely computed, not two swapped stock photos: one “flitch leaf” of procedurally generated grain is mirrored pixel-for-pixel beside itself, demonstrating the real geometric symmetry that makes bookmatched veneer panels work.

The signature GPU background renders real growth-ring grain from a fullscreen WebGL2 fragment shader and blends between two real cut-pattern distance fields as you scroll — an arched “cathedral” flatsawn field near the top, settling into straight parallel quartersawn lines deeper into the page, the same real distinction the movement calculator explains. 15 demo portfolio pieces across 5 categories with real sourced woodworking photography, a full 6-stage commission-process page, and a species-library page.
