    Started my next LiDAR and ALOS/AW3D30 DSM based project, Mike Pero Motorsport Park, known more-affectionately by the locals as 'Ruapuna'.

    There was already a Ruapuna on RaceDepartment but it's an old rFactor conversion and I think the scale is not accurate, plus it has some crazy bumps in the surface which are not really there (it's my local track and I can report the bumps do not exist).

    About
    The track surface is hot mix bitumen and runs for 3.33 kilometres (2.07 mi) in a counter-clockwise direction with many fast sweeping corners. It rewards smooth and tidy drivers.

    The track also features a drag strip, pit garages, racing school, speedway circuit and even a radio controlled car circuit.

    Layouts
    It supports six layouts, from the 1.31km "A Track" to the 3.44km "Grand Prix with dipper".

    Development
    A scene origin was defined roughly in the center of Ruapuna at 1558000, 5180000 in the New Zealand Transverse Mercator (EPSG:2193) coordinate reference system. LiDAR DEM and ALOS DSM excerpts of the areas of interest were created using QGIS. BlenderGIS is used to import and generate faces from the point cloud raster (GeoTIFF) exported from QGIS.

    The LiDAR DEM is textured with 0.075m/pixel orthophotos from Land Information New Zealand (LINZ). The ALOS DSM is textured with a 30m/pixel excerpt from the LINZ 'NZ Aerial Imagery' set pulled via WMTS in QGIS. The overall scene size is 1356 square km with some of the port hills and banks peninsula visible.

    The above was done on a 7+ year old Chromebook running Ubuntu. So please think of the planet, and recycle your old computers with Linux instead of throwing them out ;)

    that is cool. nice and desert like. not enough tracks like this in AC. but way to much surrounding area. I see your running 16 million tri`s :nerd:

    I like to push limits, both computers and cars :lol:

    but that reminds me I still need to dissolve the geometry on the ALOS DSM, it's nearly 2 million vertices alone, and some are visually redundant (flat or open areas).

    Started this on Tuesday NZ time I think -- only took about a day (the ALOS DSM geometry dissolve has been running for almost a day now tho!). But no 3D models yet aside from the pit wall, just a DEM to drive on. The work has only just begun!

    Dissolve done! After two and a half days on this Ryzen 7 (but in a single thread ugh), it took the DSM from 1942512 vertices down to 444702 using a 5° limit. Hopefully the background scenery won't kill performance now!

    You can see banks peninsula on the horizon here (where the summit road is :D):
