    Translating heavy math code from c/c++ to pascal [ Award!! ]

I could use the c dll if i wanted to, and i can use it from delphi (see one of example apps) so that header has no byte alingment problem, but the one used in delphi translated project doesn't matter what alingment it has, since it is all native to delphi / fpc, isn't it?

    savage: there's now an additional 100€ award, not just copy of delphi 1.
    alignment still matters, but I clearly see no reason why you just cannot use the c dll after fixing alignment issues or use C++ builder to compile it into .obj files and link them into your Delphi code (FPC supports this?)...translating that code into delphi means translating part of newton into delphi which is kinda awkward (eg. dVector, dMatrix, dQuaternion)...

    exactly because of that precise reasons, i am going to make changes to the car dynamics code, which i'd like to have in pascal, there is NO UNIFORM linking for at least 3 platforms on which i'd like to use this on (meaning i'd have to compile and link separately on each platform) also there are certain security issues if u use an externally linked library - people might just replace it with a hacked version and cheat.. delphi can link bcb obj files, but fpc DOES NOT link obj files made with delphi or bcb (wrong format). those dvector, dmatrix etc.. files are not part of newton, but of the sdk examples, i translated them already (but the translation might be broken)

    Did my previous post help you at all (Re: static variables)?

    I had a quick look on the code and I haven't even been able to compile it yet... Why are you mixing VectorGeometry unit used by GLScene with your own stuff It's a total mess and one can't easily see what's going on...

    I'm working on vehicle physics myself and the original C project may be useful for me as well...

    because i'm not using glscene where the code will be used, and i didn't write the original c++ code, i only translated it (twice, but both translations didn't work and i can't locate the flaw)

    well, if you get this working, you can use the code for whatever you want.

    I'm cancelling this.. it's not as if anyone shown much interest into solving this aniway.

    Hi Delfi,
    you never said if what I posted helped you at all...

    cheers,
