I would have to use a lot of vertices to make this look good. I'd like to avoid a LOD cockpit for the pilot view. Hmm ... Can you post a screenshot? The model in CVS doesn't (I don't think) have any cockpit geometry. The default sharp angle is currently 46°, which means that an octagonal surface will look smooth after the split. So it should only take one extra edge line per 90° to make a smooth edge; that doesn't sound so bad to me. Maybe there's a bug, or the default is set wrong. In any case, the threshold is tunable per-subobject; we just have to find a way to express that in the model file (the AC3D 4.0 crease parameter being the obvious candidate). At worst, you could simply identify the objects that you want smooth and set their thresholds to 180°.

No, but this one has (kind of; it's just a flipped copy of the fuselage): http://www.unet.univie.ac.at/~a8603365/bo105.ac.gz (40 kB) Here's the screenshot: http://www.unet.univie.ac.at/~a8603365/fgfs11.jpeg (20 kB) [...] it should only take one extra edge line per 90° to make a smooth edge; that doesn't sound so bad to me. No, that sounds good. I'll try that. At worst, you could simply identify the objects that you want smooth and set their thresholds to 180°.

There's very little lighting at all, so I can't imagine how the vertex splitting code could make it look any different.

Ah, I see the misunderstanding. The new code only affects lighting. It creates new vertices only to change the direction of their surface normals; it won't smooth out the visible outlines of the geometry for you. You're basically stuck having to provide a high-res cockpit; sorry. :) Andy ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

I thought that smoothing is automatically done everywhere, and that your code omits this for certain angles. OK then, I'll think about another solution ... it will probably make slower machines crawl ... :-/ m. ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel
