   Matrices from D3D to opengl
  Hi everyone.I have a difficult Task to accomplish. I need to somehow convert D3D Lefthhanded Coordinates ( View Matrix, World Martix, Projection Matrix) to OpenGLs representation of Matrices (which are Righthanded I think).Im also wondering if the OpenGL ModelView Matrix is equivalent to D3Ds ViewMatrix * WorldMatrix ?Can somebody help me out ?Many Thanks in advance,Wintermute

It might be WorldMatrix * ViewMatrix. You should never let your fears become the boundaries of your dreams. ;  Hi, That would be great ! But sry me, Im a little bad with the mathematics there, could you give me a hint or link where "transposing" is described ?--edit--Stupid me, google  But which Matrices shall I transpose, and all D3D Matrices, or after world*view ?-- end --Thx,Wintermute   [edited by - Wintermute2004 on February 9, 2004 2:23:31 PM]
