Euclid

Lumen & Logic

An antique geometry-plate reproduced from an engraved figure sheet: aged paper packed with dozens of small numbered construction figures drawn in fine sepia ink. A grid of cells is each filled with one figure drawn from a large repertoire — triangles with medians and altitudes, circles with chords, diameters and inscribed polygons, star-diagonal polygons, quadrilaterals with diagonals, ellipses with axes and foci, isometric cubes, pyramids and other wireframe solids, sine curves, spirals, lemniscates, hatched angle sectors, coordinate grids with parabolas, armillary globes, concentric circles, intersecting circles with their radical axis and external tangent constructions — with dashed construction lines, dotted vertices and little italic point letters. Every figure gets a hand-lettered "Fig. N" caption and the whole plate carries a double-ruled border, foxing specks and an edge vignette. `Construction Detail` sets how many cevians, radii and hatch lines each figure grows, `Hand Jitter` the slight rotation and scale wobble of each drawing, `Ink Weight` the line thickness, and `Columns`/`Rows` how densely the sheet is packed. The render is a single-pass, seeded `CanvasRenderingContext2D` routine and defaults to the `Landscape` canvas with the `Euclid` palette.
