maj00r	d25f20a56c	feat(track): 3D sleepers and switch timbers, blade heel and throw from templates, one rail carving pass ... - sleepers3d / sleepers3dplain / sleepers3dbed in eu07.ini: timbers put together from the begin, main and end parts of a model and stretched to their length, plain sleepers of their own model; tracks whose plain sleepers would touch are laid as one cluster, lines of timbers led by priority and turned to the bisectors of frogs and crossings at a limited rate, whole timbers under crossings, split ones between tracks with room to part them, gaps filled per rail and overlaps shortened or dropped; clusters worked out in a background thread while driving, on demand in the editor - the ballast can be left out under the beams (sleepers3dbed no) - blades get their heel and throw from the switch template or blades <heel> <throw> in the scenery; blades of double switches run on into the track linking them to the next switch - rail cutting at frogs, wing rails, movable noses and switch crossings done by one carving pass (RailCarve) - tint of the rail treads applied to the colour only, without the matte band at the frog - a switch trailed through with a movable nose set the other way derails the vehicle - self-tests: sleepercheck, sharedzones, beamsnear, throw, sleepersbg	2026-10-17 23:32:43 +02:00
maj00r	513daa52cc	merge feat/rail-crossings: the split rail code, mitred wide crossings, guard rail treads, check rail spacers and frogs for every rail profile, with the geometric switch blades moved into RailCrossings, their shape in track_rails::switch_blade and the lowering of the head in loft_span	2026-10-17 23:32:43 +02:00
maj00r	20c4b6542e	feat(track): the blades of a switch whose frog is cut from the rails are made from its geometry: the tip is where the gauge lines of both paths are 3 mm apart, the head reaches its full width where they are a head plus 0.5 mm apart, and the heel is the shortest blade whose open flangeway stays at least 58 mm with a throw of 160 mm bent like a cantilever from the heel, or straight when that does not fit as in slips; the blade is the whole rail profile lofted from the tip to the heel, cut along the head of the stock rail, with the head lowered by the drop of the blade half of the profile file towards the tip and back to the top at a 50 mm head, and thrown with knots every 0.5 m so the vertex count does not change between the positions; the stock rails get stations every 0.5 m along the blades so their curve follows the blade, the fixed rail behind the heel starts at the heel, the old blades take their segment count per path, and the self-test command blade logs the tip, heel, drop, flangeway and the gauge lines against x^2/2R and faults on a short flangeway, a heel past the throat or a change of the vertex count	2026-10-17 23:30:36 +02:00
maj00r	306555a654	feat(track): a check rail is held to its running rail by spacer blocks every 0.5 m along its straight part, laid in the same way as the spacers of a guard rail at a wide crossing, below the head from the web of the running rail to the face of the check rail, so the flangeway stays open above them; a check rail replaced by a wing rail gets none; the spacing of spacers and castings is shared by guard rails and check rails	2026-10-17 23:29:08 +02:00
maj00r	697592c4aa	refactor(track): the crossings of the rails are found in steps, the tracks nearby, the meeting of two rails with its refined place and the crossing made of it, and the crossings of the neighbours mapped on this track, and the check rails are planned, merged, kept clear of blocks and cut in separate functions instead of two long functions; path_count and path_neighbour replace the repeated choice of the paths and the ends of a switch or a plain track	2026-10-17 23:29:08 +02:00
maj00r	f67380f843	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	2026-10-17 23:29:08 +02:00
maj00r	a88774d279	refactor(track): the rail layout value types (crossings, sizes, check and guard rails, cuts, bands, fills, treads, layout) and the wheel and rail constants live in world/RailLayout.h in track_rails instead of inside TTrack	2026-10-17 23:28:42 +02:00
maj00r	a107b04fcf	fix(track): the treads of the wheels reach from the gauge line as far as a wheel 140 mm wide with the back faces 1360 mm apart does, 820 mm from the axis of a standard gauge track, instead of a flat 100 mm	2026-10-17 23:28:41 +02:00
maj00r	7100cec12f	feat(track): the texture of a shared running surface blends into the texture of the rail it lies on: 2 cm on each side of the boundary both are drawn in tinted variants of their materials that fade per vertex into the mean colour of the two treads, sampled from the texture files, so the edge of the wheels of the other track leaves a soft band instead of a line	2026-10-17 23:28:41 +02:00
maj00r	9448bd8c70	feat(track): where two rails share a running surface it takes the texture whose running surface is brighter; the brightness is read from the texture file over the u range of the rail head top, the shared parts are the block of crossing grooved rails, the nose of an acute frog from its tip to the end of the V, the through rail across a wide or grooved crossing, the frog of a switch, and the stock rails of a switch with frogs up to half the blade length where the blade grows to a full head	2026-10-17 23:28:41 +02:00
maj00r	36fb68d8f9	perf(track): the gauge lines, crossings and check rails of a track are kept until a track is made, rebuilt or removed, so laying the rails of a track no longer recomputes its neighbours' crossings for each wing rail; self-test command railtime times planning the rails of all tracks	2026-10-17 23:28:41 +02:00
maj00r	929294af24	feat(editor): self-test command guards logs each guard rail and what each of its ends and breaks is cut along: the rail of the other track, how far off its gauge line and how skewed; a fault when a cut is not along a rail, or a glued end of the frame of a crossing at a middle angle is not on the face of a guard rail of the other track	2026-10-17 23:28:41 +02:00
maj00r	2159d682f2	feat(track): rails are cut where they cross other rails: a switch with the key frogs draws its frog, wing rails and check rails from its rails, tracks crossing other tracks get acute frogs with wing rails and check rails, obtuse points, guard rails along the quadrilateral of a crossing between 20 and 45 degrees and broken rails with guard rails at wider angles, the track going through chosen by name; sizes come from the rail profile, only for the profiles default, s60, uic60 and s39, others are laid whole; rail ends left open are closed with their cross-section; switches of older sceneries, with check rails in their includes and no key, are drawn as before	2026-10-17 23:28:41 +02:00
