b71b3af66c A patch from Mathias to fix the startup at a tile boundry problem. 2005-05-26 08:13:06 +00:00

2acdd02879 Clean up various compiler warnings that have crept into the code. This 
by no means get's them all, but it's a start.

439a9fa1e4 Minor API changes to support the new sg_geodesy implementation. A few 
places now use sgCartToGeod() instead of rolling their own
approximation.  And YASim is now using exactly the same 3D coordinate
system as the rest of FlightGear is.

071a3d99b9 The code to find the highest hit below you didn't work quite right when 
reinitializing at a new location.  This should fix the problem.

f6fad7f000 Tweaks and massages to the ground intersection code. Most of the changes 
are cosmetic, but we now have a combination of code that seems to work
very robustly.  I was able to land the yf23 at about 130 kts on the lower
level of the bay bridge and then taxi the entire length.

ca6067cbc0 With this patch, you can fly under bridges, then turn around and land on 
them lengthwise.

0f1c24bbed Fix a terrain intersection calculating bug. The code wasn't quite handling 
traingle strips right ... it was mixing up the vertex ordering slightly.
Oh what the heck, it was really screwing up tristrips.  Everything else looks
correct though. :-)  Hurray for the red book.

f46bda0621 A bounding sphere may be empty, which is perfectly valid. 
Such empty spheres have negative radius, but undefined center.

58a001ad32 Patch from Norman Vine: 
Yikes  --
Looks like I broke the scenery.current_normal when I last
reworked the hitlist code.

I guess this is proof that no one has been using it.

c5f6293f17 Fix for vanishing-model problem: models are drawn in the same scene 
graph as the terrain, except for internal cockpit view.  The SSG
scene-graph variables (except for the lighting root -- I'll get that
later) are now held in globals.hxx.

FGModelMgr::draw() is obsolete; I'll remove it in a future revision.

464f036f35 Here is a cleaned up hitlist that should solve the PLib conflict 
and fixes a 'potential bug' if the FGFS View code were to change

I also consolidated the specialized IntersectLeaf()
as they really didn't gain us much outside of their having
'more direct access into the SSG controlled data'

I would like to see the fgCurrentElevation functions moved
out of hitlist.cxx.

The one obstacle is their being dependent on my PLib
auxillary functions

ssgGetEntityTransform()
ssgGetCurrentBSphere()

code has been run through astyle with the default options
