new experimental win32 build with SSE and Multithreading

[Frank M.]

Hi all,
I think it its time to prepare for a new release of gravit.

There have been a lot of changes by Gerald an others since Release
0.4.2, especially in code compatibilty with OSX and Linux, and also a
few other new or improved features.

I have uploaded a new windows binary compiled from my current fork of
gravit 0.5.1. You can find it on github
(https://github.com/FrMo/gravit, downloads, file
gravit_0.5.1_win32_snapshot2011-06-29.zip).


Please give this version a try.

You can simply unpack the ZIP somewhere (no install needed), and run
gravit.exe. Compared to release 0.4.2, the physics engine is up to 30
times faster now.

------------------------------------------------------
changes (experimental):
- quick fix for issue #11
- center possitions & velocties after spawn

changes since release 0.4.2
- SSE optimization
- Multithreading
- screenshots in PNG format
- some GUI changes and minor improvements

open issues: fix physics (http://github.com/gak/gravit/issues/12)
------------------------------------------------------


If you find issues, you can report them at github, too (either in my
fork, or in Gerald's master branch):

* https://github.com/FrMo/gravit/issues?sort=created&direction=desc&state=open
* https://github.com/gak/gravit/issues?sort=created&direction=desc&state=open

If you have the required libraries, you could also check if you can
build the gravit source code on your machine. Get it from
https://github.com/FrMo/gravit or https://github.com/gak/gravit .

For Windows, Visual Studio 2008 and MingGW gcc should be able to
compile the code (the windows build files still need some cleanup ...
this is already on my agenda )


best wishes,

Frank.

I have just build a 64bit version, too (had to recompile SDL and all
other libs for 64bit ...)

You can find it next to the 32bit binary, at
https://github.com/downloads/FrMo/gravit/gravit_0.5.1_win64_snapshot2011-07-02.zip


best wishes,
