As an experiment, I'm going to kick off an open-source track project. Anyone who wants to contribute is welcome to!
The idea here is that future sims/mods/etc will not be in some grey area about using and converting the track. The plan is to release everything under a Creative Commons licence, blender files and all. Also that way if I get hit by a bus or whatever the data can survive.
So, I got started last night in QGIS. Got 4x4km of the 1m LiDAR DEM into Blender and draped 20cm/pixel ortho-photos over it. The scene is properly geo-referenced using the GDA94 zone 55 (EPSG:28355) projection at an origin of 737420, 6295420 in that co-ordinate reference system.
This should help to avoid the mercator scale issue no-one seems to bother engineering out of most tracks.. FWIW, the only Bathurst I've driven which I think got this right is in Gran Turismo. Image to illustrate difference between Mercator map and actual country geometry:
Was a bit ambitious with the DEM though, 16 million vertices in one object, going to divide and conquer it later today.
