Fixed texture translation so step and scroll values work with interpolation tables as well. Moved step/scroll calculation to utility function to improve code readability.
This update adds the ability to do multiple texture transforms (Steve B. thinks supporting them at the plib level would be inefficient, which is probably true).
Removed units (e.g. "_m") from texture translation property and variable names since the texture translation values are dimensionless.
Added the ability to specify a scroll factor for stepped texture animation that needs to scroll smoothly when approaching the step interval (e.g. odometer movement).
- Added documentation for SGCloudLayer
- Updated the SGSky interface a bit to make it more sensible, flexible,
and generic. This requires a code tweak on the FlightGear side as well.
the dimensions provided.) We draw the sky dome before everything else
and draw it with depth buffer off so it really doesn't matter, but it just
makes a little more sense this way.
Updated a few doxygen comments.
1. Added support for defining arbitrary rotation axes using (x1,y1,z1), (x2,y2,z2). The center is calculated automatically (midpoint on line) or you may specify an alternate "center" using the current scheme. This makes it about 100 times easier to animate flaps, ailerons, etc.
2. Added support for plib's ssgTexTrans. This will allow more sophisticated 3D instrument features by allowing the texture mapping itself to be animated. Included function for "texrotate" and "textranslate". They configure the same as the geometry, except the arbitrary axis definition is not necessary (textures are flat).
