    error message "D3DM Wrapper Driver: ERROR: Vertex Processing needs clipping"

    Green Belt

      Hello,

       

      We are porting a Windows CE application from DirectX to Direct3DMobile, so far it works fine but performance is an issue. We noticed that the driver outputs the following error:

      D3DM Wrapper Driver: ERROR: Vertex Processing needs clipping!

       

      We were able to reproduce this problem with (a slight modification to) the D3DMobile tutorial application 5 (textures).

      In the function InitGeometry, multiplied the X and Z position of both vectors by 3

      example: pVertices[2*i+0].position = VECTOR3( (float)sin(theta) * 3,-1.0f, (float)cos(theta) * 3 );

       

      The cilinder then touches the sides of the window and the driver outputs the message.

       

      What are we doing wrong?

       

      We have Windows CE 5 and 6, using the IEGD 10.3.1 driver on a 945GME chipset.

       

      Thanks in advance,
