BridgeSketch 3D

A quick visual tool for bridge concepts.

By Anthony Chéruel

Starfield and grass species adapted from CK42BB/procedural-stars-threejs and procedural-grass-threejs (MIT); physical sky after Tw1ddle/Sky-Shader and the three.js Sky object (MIT).

Version 0.6.2

A road profile table (chainage from the west abutment axis, elevations from a chosen datum) with CSV export, full-size procedural trains, fuller tree crowns with denser woods and shrubs, more natural painted girders, no cast shadows at night, a clean 3D view without its title, a flush abutment side and tapered caps that meet their columns, and a much faster Reveal structure.

Version 0.6.1

New pier shapes (rounded or pointed wall ends, flared hammerheads, inclined portals, V piers), an optional light bloom, realistic example concepts, faster parameter edits, clear-coat vehicles with contact shadows and a realistic paint mix, and gull-like birds. Folded parameter groups with a value summary, a reorganised Site tab, formulas in the numeric fields (for example =2*17.4 or (12+3)/2), a File menu with Open, Save, Undo and Redo (Ctrl+O, Ctrl+S, Ctrl+Z, Ctrl+Y), a modified marker, a local autosave with a restore offer, and an option to turn the birds off.

Version 0.6.0

Crowned or uniformly sloped deck, continuous girders by default, NEBT intermediate diaphragms and full-width haunches, girder screens, linear cap tapers, the Samuel-De Champlain architectural railing, a 3 m post grid and railings continued over the return walls, crowned and ditched crossing roads (one-way pairs), open-ground spans, a double truck, a seeded starfield, three grass species, concrete finishes, a high-quality PNG snapshot and a phone layout.

Version 0.5.6

Time runs by default (15 min every 5 s, stop with ❚❚), golden hour before sunset (19:00), 1–4 concrete boxes under one deck, a meandering river in the profile-following terrain, Orbit off by default, Stats at the bottom centre.

Version 0.5.5

New structural systems: prestressed concrete box girders, rigid frames (portique), strutted frames with inclined legs, concrete or steel deck arches and tied arches. MTQ Type 311 barrier and 311 A+B steel rail, 12 m street lights with a single davit arm, autumn scenery with falling leaves, moving cloud shadows, pier water marks and a terrain that can follow the road profile. Faster rendering: Balanced by default, an Auto quality, tree and grass levels of detail, on-demand shadows and a Stats overlay.
