RE: [Flightgear-devel] Gear animation tutorial
Josh Babcock I just made up a tutorial about making gear retraction animations run smoothly with complicated landing gears. It's still missing the final animation code, but I thought I'd throw it up to see what everybody thinks. It's got lots of in-line images, so be warned. I'm considering changing this to in-line thumbnails hotlinked to the full sized images. Please give feedback. http://jrbabcock.home.comcast.net/gear-tutorial/gear-tutorial.html Gosh, Josh, what an effort. Well done. Couple of points. First, I model the gear with the oleos extended, which helps with getting the compression right. Most drawings show the gear with the oleos at some intermediate compression. Some interpretation/intelligent guesswork is usually required. Second, sometimes the movement of jacks and draglinks etc. is too difficult to model well, so I cheat and hide them once they can no longer be seen readily (I do that anyway to save vertices). And one typo: separate. I'm impressed!

You have no idea how good your timing is on this one :-) I've been putting off doing the gear animation on my Lightning for a while now, but with this sort of insight I'm certain the job will be much quicker. Like so many other things in the modelling process, a step by step example can save so many hours of slaving away learning the hard way. It's got lots of in-line images, so be warned. I'm considering changing this to in-line thumbnails hotlinked to the full sized images. I like it just as it is, myself - I find that having to open bigger pictures from in-line thumbnails is just a nuisance when trying to juggle several open windows or browser tabs, even with a sane window management setup. Of course, having had broadband available here for less than a year I remember well the plight of the dial-up user; but even then, for tutorials I just downloaded the whole lot and _then_ read them; saved time and bandwidth in the long run. The full-size in-line pictures probably make that process even simpler, if anything. Please give feedback. OK, it's great - thanks! Obviously the final animation code will be nice to finish it off, but as it stands it looks excellent. I'll let you know if I get baffled at any point once I start working through it.

I will add this, and a section for dealing with gear-compression-norm and gear-compression-m. I'll also add a LOD section. The neat thing about this method is that it's so east to get everything in the right position, so you don't really need to hide it until you close the doors.

The full-size in-line pictures probably make that process even simpler, if anything. Maybe I can compromise, and interlace the images. Can png images be interlaced, or would I have to use jpgs?

I need to get a screenshot from FG, as well as the distance that the gear compresses, which is a bit of a problem right now. Putting in the rest of the code and the second missing image should happen today.
