I need some help on DelphiX. I write a game like stuff, and I don't know some functions' usage. These functions are: DXDraw.D3DRM.CreateWrap(...), DXDraw.Camera.SetOrientation(...), for example. I don't understand any of directions, and ups. Maybe I will need a 3D course, but I don't have much time for it, I just want to know, how to simply use these functions, and how can I set these functions' parameters, of course simply.
Thanks anybody for help!

As much as i cannot recommend moving into unsupported and old graphics system, here is some instructions with original functions from DirectX.pas:


function SetOrientation(lpRef: IDirect3DRMFrame; rvDx, rvDy, rvDz, rvUx, rvUy, rvUz: TD3DValue): HResult; stdcall;

plRef is Frame that sets the base rotation from which the camera is rotated based on vector and normal-vector.
If you want to look right in front, the values are
0,0,1, 0,1,0


function CreateWrap(wraptype: TD3DRMWrapType; lpRef: IDirect3DRMFrame; ox, oy, oz, dx, dy, dz, ux, uy, uz, ou, ov, su, sv: TD3DValue; out lplpD3DRMWrap: Direct3DRMWrap): HResult; stdcall;


First parameter is one of TD3DRMWrapType values, then comes the frame (not sure what it was for), and then some mysterious x,y,z values and finally set the wrap variable.

More instructions can be found from DelphiX's own samples, which use these methods mentioned here.

Thanks, User137, but in CreateWrap function, what are those mysterious x,y, and z values? Are they Sine or Cosine, etc. values, or what? So, I meant that. But thanks!
