I use DirectX map a three-dimensional wave, were drawn with the method of index buffer and now to use the mouse to select one of the peak, and have a look at its coordinates, how to implement,
I looked on the Internet using D3DXIntersect function available ray fellowship with grid model of triangle, but the point I am not the mesh, but to draw, how to get,,, I just contact with DirectX, do not understand, please grant instruction,

Three-dimensional wave matrix should be a margin, as long as the mouse capture, converts the world coordinates of the mouse into rows and columns of the matrix, pick up the ranks of the recently shown that value is ok,

Concrete examples we can see qt data the visualization of the code,

Specific how to operate it, just contact this, don't know much about,
