    Simplest 3D physics engine for Delphi, what to choose?

    Hi.

    I saw today one C++ OpenGL physics tutorial:
    https://www.youtube.com/watch?v=wbu5MdsFYko

    Using Bullet. Is there port of this to Delphi / FPC?

    I liked the falling cubes demo.

    Maybe there is some simpler physics engine for 3D?
    I dont need much.

    But i just thinked about adding something like this to my map editor.
    Selectorblocks falling apart or something.
    Or maybe when deleting whole selections of blocks in map, they fall down and disappear.
    There will be not so many cubes like in this demo of course.

    This is just for fun and maybe like easter egg.

    But there are so many engines and i dont know what to choose.
    It would be best if i could just pass him my vertices of my objects / meshes and it takes care of the rest.
    If it will be too complicated, i will forget it. But i would like to try.

    What you guys recommend?

    nxPascal doesnt have something?


    Thanks

    Apart for the FPS demo where bullets are bouncing around in almost torus shape free polygon model, and player itself moving on rough terrain, no. It is much trickier to simulate bunch of falling cubes, and that kind of interaction, than simulating a single collision. 1 option seems to be Newton

    Thank you for the reply.
    I looked at Newton. And even found headers for it and some demos from JediSDL. Which i have on my hard drive already.
    The SDLNewtonBasicDemo.dpr seems to be the one i need.

    Falling cubes, using gravity.
    But since i dont know almost nothing about Newton engine i have to first start with that example.

    By first look, it seems easy enough. But thats just the first quick look.
    I will let you know how it goes.

    Selectorboxes in map editor are almost 99% working fine now.


    I have so many fun ideas, picking selectorbox, throwing it somehow, or releasing it, so it will grab some of the building from map and it falls apart almost fully. I know these are not features of map editor or they shouldnt be. But consider it as easter egg.
    I think i have to start play with Newton and the boxes demo. Should be lots of fun.

    Because i need something else also besides map editor project, working on 1 project gets really boring quickly.

    So it might not be bad idea in contacting him.

    Thanks, too bad there are no docs but i sent BeRo PM and asked if its his engine and if he has any docs.
    I could use the examples also. Just have to devote some time to it
