ThorstenB 7b0c25f91e #83: John Denker: Set correct file modes 
Sources shouldn't be executable.
 2011-02-19 11:54:10 +01:00
Torsten Dreyer e988dc0e42 Fix bug in SGMisc<T>:: normalizePeriodic() 
SGMisc<T>::normalizePeriodic(min,max,value) returned zero for
all values less than min.
Example:
A call of normalizePeriodic(0,twopi(),-pi()) returned zero
where the correct value would be 3*pi().

mfranz f91d96b51a - fix one broken #include path (in a not usually compiled test app) 
- turn four #include paths from the "foo" form to <foo>

The quotes form is normally only used for headers with path relative
to the including file's path, though the standard doesn't strictly
mandate this. This is consistent with the rest of sg, it makes the
code's intent clearer and helps to find headers. (And it's a few
milliseconds faster, too.)

jmt 94942d1ac4 Add some syntactic helpers to allow distance/course to be queried between 
two geodetic points. This still entails a full _geo_inverse_wgs_84 call,
but makes call sites neater.

ehofman d4c7e95092 Replace SG_USE_STD() by using std:: 2008-07-28 07:52:13 +00:00
ehofman 733e6fa14f Reduce compiler.h to almost nothing (but it's worth keeping around I think, for 
the MSVC and MipsPro warning stuff).

As a result of this patch, simgear/sg_traits.h can be deleted. So can SGCMath.h,
but I'll do that separately.

There is one more 'mechanical' change to come - getting rid of SG_USING_STD(X),
but I want to keep that separate from everything else. (There's another mechnica
l change, replacing <math.h> with <cmath> and so on *everywhere*, but one step a
t a time)
 2008-07-25 18:35:40 +00:00
ehofman cd72eb20c6 Attached patches remove BORLANDC, and hence SG_MATH_EXCEPTION_CLASH and SG_INCOM 
PLETE_FUNCTIONAL from SimGear and FlightGear.

As a result, SG_HAVE_STD_INCLUDES is now *always* set, so I will get the boring
fixes for that done, but separately. I'm still auditing the other things in comp
ilers.h - there's a lot that can die now BORLAND is gone.

timoore d219c5c4c6 Don't include <iostream> and "using" declarations in header files 
<iostream> sucks in expensive initialization of the standard streams
and isn't appropriate in a header file. Use <istream> and <ostream>
instead.

using declarations should never appear at global scope in a header
file; source files get to decide what they want to use in their
namespace.

timoore c7dab4abea rewrite of sky dome code 
Add more points to the dome, giving it a dome shape rather than a
dunce cap shape.

Represent as OpenGL DrawElements instead of as triangle strips.

Only calculate have the sky colors and reflect those across the dome.
