Re: [Flightgear-devel] announcing star trek runabout shuttle and
Hi Martin, That quote comes from the credits file in the danube package, written by Matthew Allen, complete with misspellings and discontinued email addresses. My interpretation of non-commercial is, not to be sold by a business without compensation. I don't see FlightGear as commercial, or for profit. I received free (mostly), and give freely (with same conditions). As I read the GPL, I am fine with that. I did add animations to what I downloaded, but I don't think that violates the original work. I am not completely sure how to regard shuttle6, as I did more than convert the mesh to something usable, I did add to it. But I still credit the original author, but don't expect my name pasted all over my accomplishments. Does that cover every angle? Did I mis-interpret anything?

I don't remember if there is an optimization pass in the ac3d loader that would aggregate individual triangle of the same OpenGL state. Ok, good. That explains a couple meshes I downloaded and tried to get working, 41000 and 5 vertices is too many. Thus, I kept working on the model I already had for 2 years. 32,768 maximum vertices. Hmmm... I did get segFaults (for a long time) until version 19, when the exported .ac file (less one mesh object) finally loaded, and version 20, when I was able to switch over from .3ds exports to .ac. The count in this time frame was from 38,100 to 34,700 polygons, and around 22,300 vertices is when the .ac file started working. But it was not a definite number, some files with more did load, and some with less did not. I have that much documented in my archived notes. Either I'm missing something, or there is another key to the failure, yet to discover. I suspect: Too many vertices too close together, or holes in the mesh, with overlapping polygons and reversed normals conflicting for outward appearance. Having re-faced those areas too many times, I scream enthusiastically All GONE!! I was hoping the backtrace could provide insight. I could re-generate some .ac files for testing?

Re: [Flightgear-devel] Interesting blog: Flightgear versus X-Plane
The big thing is that you need to be able to shell out to rsync. I wrote this as a single evening hack so I wasn't going to reimplement rsync on windows just so that it could all be rolled into one big monolithic app. But if you have rsync available which shouldn't be all that big of a deal on windows, it should be possible to get terrasync running on win32.
