At the moment we work on some different parts in DftD. While Tj has reworked the torpedo code to support all the pattern torpedos like the “Zaunkönig”, Luis is rendering a lot of textures for the new valves station. There you will be able to control the flooding of the ballast tanks to have a heavily realistic simulation of the submerge process. Because it takes some days to render just one of these textures(and some months to model and texture mapping them) this will be finished not before May or June but the code to handle the buoyancy is already implemented.Myself is working on the terrain rendering. While Tj implemented the really impressive geoclipmap render some time before, it now uses the raster data from the ETOPO1 project to have mostly realistic landscapes and bathymetry in DftD. The next steps on the terrain will be extra detail from multifractal noise as the ETOPO1 dataset has only a resolution of one arcminute and some sub-detail added by normal mapping. If you want to see the terrain in action, just get an actual SVN snapshot. It’s not necessary to download the terrain dataset as DftD will produce a zero-height landscape(with some noise) if the terrain files are not in place.
