Once upon a time, you were sitting and writing: ... I was wondering if there has ever been talk of exposing 3d models through a metalanguage in XML, or maybe to a spec such as SVG (though I guess SVG is 2d, not 3d). In this way, a person might not have to run off and download/pay for/learn some heavy duty 3d program to render some sort of basic aircraft frame, or building, or even cockpit. FOA, I think VRML is the answer to your question (??), not neccesarily in FlightGear. Besdies, I do no underdtand if you refer the difficulties in rendering, or modeling. For instance, you can download GMAX for free (from Discreet's site), which is a freeware modeler based on 3D studio MAX. Moreover, PLIB has the ability to load 3D scenes of a reasonable amount of formats. All the best, E.Y ~ ___ Elad (elady)_@__ ___ ( \ J.

Besdies, I do no underdtand if you refer the difficulties in rendering, or modeling. I would use VRML if plib supported it fully. Yuck - VRML as written has LOTS of problems in that it tries todo way to much. There are good reasons appicaions didn't just 'adopt' it Moreover, PLIB has the ability to load 3D scenes of a reasonable amount of formats. In practice, the only formats I've seen work with plib for fully-textured models are AC3D and MDL. All of the other loaders seem to be half-finished. In all fairness Steve uses AC3D and others added the MDL format so we could read M$FS modeels, the other formats do have basic functionality and are a good start FWIW -the IMHO 3DS loader is pretty good If X3D ever takes hold it 'might' be a good candidate http://xsun.sdct.itl.nist.gov/~mkass/devel/html/X3DHome.html http://www.realism.com/Web3D/x3d/Web3D-2002/X3d-XmlSyntax/main.htm The problem with AC3D is that it really needs a propriatary editor even if it is an inexpensive one Norman ___ Flightgear-devel mailing list [EMAIL PROTECTED] http://mail.flightgear.org/mailman/listinfo/flightgear-devel

What I need is the ability to animate the textures using texture transforms. Would that be difficult to do David? I'd need to able to slide and rotate. At some point we would need to be able to do some sort of multiple texturing or decals as well for more detail. That's doable, but it might also be time to think about scripting.

re: [Flightgear-devel] question about 3d models
It's not the I _really_ feel the need. It is just that the few 3d tools I have taken a look at, Maya, Blender and one other one (can't rememeber the name, it was a bit ago) are complex to use. Harder, it seems to me anyway, than thinking in terms of edges and nodes in some 0,0,0 centered 3d space, drawing it on a piece of paper, making a list of nodes, and typing them in somewhere. Having said that, it is probably my issue that I don't really _want_ to learn a 3d modeling tool. For FG, I would love to be able to put together a really simple 3d model for the airframe, and a really simple 3d model for the cockpit, where they only (for me) need to be good enough to get the perspective out of the cockpit right (view over the dash, view out the window while on base turning to final etc ...). Eye candy could be for those that _do_ care about 3d modeling. It's not a big deal. I'm just enjoying hacking around with FG right now, trying to understand the parts, and trying to figure out where I might be able to contribute a little. I am also doing a little research and trying to collect a little data here and there in the hopes of maybe trying to put together an aircraft a'la a mooney type of aircraft. I starting looking at and found some data for the commander series of aircraft as these are a'la mooney with a high performance single, running ~200kias or more at cruise, seating 4 people with baggage at max useful load and having the low wing design. I am also playing with a GUI front end for dealing with configuring flight gear, starting with simple stuff like being able to select aircraft, airport, time of day, clouds, weather etc. Since all of this info is laid out in XML files (I wonder who influenced that design ? ...) I am finding this to be an intuitive project. I do wish the was an XML Schema or DTD to help me understand what the possible/expected permutations of the XML config files was and to help my understand what the enumerated values were for some of the elements, such as cloud types for instance.
