Hy. I have a mesh to rotate by this parameters: <rotate>0.57735 0.57735 0.57735 -240</rotate> -240 is the angle ok , but the probably vector 0.57735 0.57735 0.57735? I must scale in x,y or z component ? and how scale for each component? Thanks

Looks like that might be the x,y,z component of the axis around which to rotate by 240 degrees?

mmm....
i use directx , how set up rotation with
<rotate>0.57735 0.57735 0.57735 -240</rotate>
i have :
D3DXMatrixRotationX(&mxRotate1,-240);
D3DXMatrixRotationY(&mxRotate2,-240);
D3DXMatrixRotationZ(&mxRotate3,-240);

where mxRotate1,2,3 are D3DXMATRIX

what is the function for rotate the object?
thanks
