maj00r	1fa7dee5d6	fix(track): at a crossing at a wide angle the floor of the flangeway between a running rail and its guard rail is laid only where real crossings have it, as the cast floor of each corner up to 0.3 m past the rail of the other track and as separate spacer blocks every 0.5 m along the rest of the guard, and the floor takes its texture across its width at the scale of the head instead of one stretched column; the wheels of the other track roll over a guard rail across their whole tread instead of only over the head of their rail; and when the tracks cross at nearly a right angle the treads of the other track are laid as plain spans along the rail instead of lines running almost straight across it, which left fins standing up at every edge of a tread	2026-10-14 12:43:36 +02:00
maj00r	2a5dda1509	feat(track): at a crossing at a wide angle the tread of the other track is laid where its wheels roll over the mitred corners: the part of a guard rail under the running rail of the other track becomes a running surface in the shared tread material instead of matte, and running rails of different materials share the tread over the rolled band of the other track instead of over a square span; wide_tread draws the edges of the band from the crossing itself, since the gauge lines meet in one point at right angles, and a tread gives its own fade, widened for bands lying across the rail; treaded keeps the matte parts of a guard rail matte, lay_treads splits guard rails at their treads, and a piece of no triangles is not inserted	2026-10-14 11:25:34 +02:00
maj00r	572ee569dc	feat(track): at a crossing at a wide angle every head of one track meets every head of the other in a mitre from the corner of their flangeways to the far corner of the heads, the way the corners of a cast diamond look, so the running rails and guard rails of both tracks form closed corners and only the flangeways stay open, instead of the rails of one track going through and the other ones glued to their sides; corner_cut gives the mitres, as bends of the running rails and as miters of the guard rails; the fit of a loft end to the profile of another rail and the field and gauge outlines of the rail profile are gone with the gluing	2026-10-14 11:08:02 +02:00
maj00r	f27ed682c0	feat(track): the guard rails of a crossing at a wide angle reach a metre past the rails of the other track instead of 0.3 m and open their flangeway over 0.6 m at the ends, the way the guard arms of the corners of a diamond run out on real crossings, the reach and the flare are the constants guard_reach and guard_flare shared by the plan and the layer	2026-10-14 10:53:28 +02:00
maj00r	701d82d1bd	refactor(track): the cap of a lofted rail end takes its texture from cap_texture and its triangles from ear_clip instead of computing both inside cap_loft	2026-10-14 09:57:04 +02:00
maj00r	74ae36e33a	refactor(track): the plates, fillers and check rails of a rail drawing are made from one box_profile and one helper for both sides, and the colour of a tread is sampled by sample_dds and sample_image into one colour_mean, a block of a DXT texture decoded by add_dxt_block, instead of one function	2026-10-14 09:55:24 +02:00
maj00r	c9e492bb3e	refactor(track): a rail is laid by the class TTrack::rail_layer instead of one function of lambdas sharing a current material and the bends and fits of the ends; a piece of rail is a rail_piece value with its material, the ends of a run are passed as piece_ends, the bands across the top of the head of a running and of a shared tread are laid from one table each by lay_top, the guard and check rails take their flared offsets from one helper, and the grooved profile is split by split_grooved and cut by top_cuts	2026-10-14 09:40:28 +02:00
maj00r	278fb88bb3	refactor(track): the rail code is split by concern into gauge lines, crossings and check rails, rail materials, rail profile measuring, planning the cuts and laying the geometry, instead of one TrackRails.cpp; rail_offset reuses nearest_distance and lateral; TTrack::rail_dimensions measures the profile through track_rails::measure_rail	2026-10-14 09:24:52 +02:00
