I'm specifically interested in the "markings" part (although I'm also curious at how you want to implement softly rounded curves without breaking the current concept of texture display). This might require information which is currently not in the scenery files, such as the actual position of the centerline and width of the linear features. The triangles don't represent this information anymore, however it is available from the scenery sources (e.g. the scenery database). In general, making this information available in a suitable format shouldn't be a technical problem (maybe one of available manpower for implementing the stuff required, but that only means that it may take longer). Another possibility - at least for simple roads - would be to add a centerline to the road texture and make TerraGear create an appropriate texture mapping similar to how it is done currently in genapts for the taxiways. Unfortunately, the part of TerraGear which creates the texture coordinates does not know anymore that the polygon it is currently operating on originally was a linear feature (blown up according to its width to a polygon). So this approach might require some reorganisation of the TerraGear architecture. Given that the current architecture is quite complex (mainly due to the fact that the task at hand is complex) I don't think this is feasible without risking to break anything to a larger extent. When we're discussing about runtime creation of textures we might also get into discussing blending of ground textures. In that case, we should keep in mind that in reality not all types of landcovers actually blend into each other. When flying overhead forest areas - especially dense forest - these typically do not blend with surrounding agricultural or greenland areas, at least not in "civilised" areas where man tends to create sharp corners by land usage. That's actually not related to this specific discussion, but I wanted to note that before I forget.
