Yeah - none of my models could be regarded as low-poly. Then again, the shapes of the models I tend to do are quite complex and not a simple tube like the majority of airliners. There's quite an overhead in doing the detail stuff like the engines and u/c, but I try to ameliorate that by de-selecting all the u/c stuff when it's retracted. I figured out the single-sided polys thing too:) The vertex count is also increased by having to split all the surfaces to avoid the smoothing glitches - every adjacent pair of edges that have been split will have twice the number of vertices but until a better solution to the smoothing problem's found I can't see a good way around it. The poly count is an issue I've thought about quite a lot but I don't think I can acheive the same level of detail and smoothness without using a lot of polys, and as far as sims are concerned there's an irreversable trend towards greater realism where that detail and smoothness is needed. One aspect of the problem is that the renderer is polygon based - whatever gets rendered has to be converted to polys (triangles infact). If it were possible to use a spline based renderer the models wouldn't need to be as complex, at least for smoothness reasons. I'm not aware of any h/w based spline renderers although I believe they're being worked on. Trim curves on a spline surface in h/w would be nice too - ideal for cutting out the windows:) LeeE _______________________________________________ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
