maj00r	59446f9a98	fix(track): flat rail frogs have no plates in the V; the shared running surface of a nose leg goes from its tip to where the wheels of the other track stop reaching its head, on the leg only and not on the wing beside it; the stock rail of a switch is shared up to a quarter of the blade length, where the blade head is half its width and takes the wheel	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	2f8aeb24c0	fix(track): a crossing of grooved rails is one flat block where their lofts overlap; the rail cut by the other covers the roundings of the rail going through, the tops in the block are flat in one texture, the plates of the V reach up to the rail top, the walls of the cuts are lit and textured as walls, and the nose between two flangeways starts blunt at the width of a nose tip instead of a thin sliver standing in the groove	2026-10-17 23:28:41 +02:00
maj00r	9343ebcb13	feat(track): frogs and crossings for every rail profile; grooved rails share the floor of their grooves where they cross and need no check rails, the V beside the rail going through is one block where the lofts of the rails overlap; the nose of an acute frog of flat rails is filled between its legs as far as their lofts overlap, like a cast insert	2026-10-17 23:28:41 +02:00
maj00r	59f1a5a144	fix(track): the lowest of two height lists also takes the points where they cross, so the top of an obtuse point rail is not cut narrower than its sides; the end of a short neighbour track joined at a crossing is the nearer one, not any within half a metre	2026-10-17 23:28:41 +02:00
maj00r	1a3a38e96d	refactor(track): one plan projection, cross product and meeting of two lines in plan for the crossings of rails, the frog of a switch and the check rails, in place of copies in each	2026-10-17 23:28:41 +02:00
maj00r	405081e81c	refactor(track): the rails of the two paths of a switch are laid by one loop for left and right switches alike, the side of the blade of a path and the blade itself come from one place, used when a switch is made, thrown and its frog found	2026-10-17 23:28:41 +02:00
maj00r	e324eb10f9	perf(track): pieces of gauge lines whose bounding boxes do not meet are skipped before they are intersected; self-test railtime logs how much of the time goes to finding the crossings	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
