This is true - particularly about documentation. Inline comments would
help, too. I prefer (and we will continue to do this for JSBSim) that dt

I think I agree. When we go about fixing this up, I think we should
pass a dt to the modules which would be in units = seconds and of
type double.

This is ridiculous. dt is short for delta T. In a 100 Hz
simulation, the
corresponding dt is 0.04. For 120 Hz it's 0.00833. For people that
do simulation for a living this is one of
I've just checked in changes to add a billboard animation to
FlightGear 3D models. The billboard animation causes an object (or
entire model) to rotate towards the camera about its z-axis and,
optionally, its x-axis as well. Here's the XML wrapper for a sample
billboarded tree (only 4 vertices)

Feel free to play with the sample tree and to compare it to the
non-billboarded tree. I don't know which approach would be better for
an entire forest:
1. The non-billboarded tree has 18 vertices (or so), but doesn't
require any special dynamic transformation.
2.
