Improvements to the cloudsystem:
- A new xml format
- Texture indexing based on the position of the sprite in the cloud
mass, allowing more control over the texture set.
- Improved fog and shading
- Better sprite distribution
- A more natural distribution of clouds, so no more obvious grids.
1. by using center/x-m and axis/[xyz]
2. by using axis/[xyz]1-m and axis/[xyz]2-m
The translate animation only supports method 1. and here comes a patch that
enables method 2 for this animations, too.
pun intended) that I'm touching the time library.
Brian Schack reported that the traffic scheduler messes up the timestamps
of the atlas network output. As it turns out, the c library functions
asctime, and gmtime use a static copy of the tm struct to do the internal
formatting. Our linux port of the SGTime class, incidentally, also stored
it's master time stamp in this very same struct. Thus, formatting an
arbitrary time value, would have the unwanted side effect of time travel.
Usually, this would go unnoticed, because the actual time parameters would
be updated before any damage could be done. But unwanted side effects, as
in Brian's example could occur.
On the MSVC port this appears to not have been a problem. Since that port
used a copy of the tm struct to store it's master time stamps. Since the
MSVC code also compiles cleanly on linux, it seems to be the way to go to
use that approach. In addition, it also removes some conditional compile
directives.
I've only run a short test, but didn't see any undesirable side effects.
- Added a SampleStatistic class (from the old deprecated libg++) library.
- Make time statistics and printing conditionable
- Added an interface function to switch time stamp collection and printing
on and off from the application (defaults to off).
* on cygwin, isnan is declared in ieeepf.h
* CYGWIN is a special case in that it is windows based, but sometimes
folows unix conventions. SGAtomic compilation failed on an illegal
volatile type cast without the additional __CYGWIN__ define check.
