  Hy.How i can find the position of a mesh in the word space?Is usefully for switch the camera closest to an object.thanks.   
  you would take the local matrix and multiply it with the world matrix I believe   ;  can you post me a link or two lines of code?thanks   ;  up up   ;  word space?   ;  If you have a world matrix that you use to transform the mesh for rendering, then you can access the translation part of the matrix by pulling out the _41, _42, and _43 elements of the matrix.  Those three components from the X, Y, and Z values of a vector representing the position where the mesh will be centered.
