I've been using TTS 1.3 to extract bathymetrical terrain data for subsequent blending in PS. My challenge is to present a blended shaded relief with texture shading to show seabed forms that range in vertical scale. I have areas of high relief (20m) , and then areas of very low relief (0.2m). It's a sort of bimodal distribution of relief. The typical approach is to exaggerate the z value until the areas of low relief show structure, at the expense of high relief which is now grossly exaggerated.
TTS lets me pull low relief detail ( Rippled Scour Depressions) to be masked and blended back into a pseudo realistic representation of the seabed.
I've stuck a problem, TTS 1.3 routinely crashes on importing .flt files and ASCII grid files of grids over 1000 x 1000. TTS will sometimes open the file and display the map window, then crash on rendering. I've used Manifold 8 and QGIS to create the DEMs.
I'd appreciate if anyone else has seen this behaviour and report on file size limitations. I've got a project coming up of 30 000 x 15 000 res, so I'm keen to get a workaround!
