  • Page 4: Introduction

    3D Solutions 1 1 1 1 Introduction The DirectX Visualizer enables one to view the output of 3D applications or games on Philips 3D displays even though the applications have not been designed to support them. It does this by intercepting the interaction between the 3D application and DirectX.
  • Page 5 In some cases it is possible to build support for this application into a later version of the Visualizer, but this will have to be determined on a case by case basis. 01 April 2009 ©2005-2009 Philips Electronics Nederland B.V. 5 of 26...

  • Page 6: Compatibility

    The Visualizer is expected to work on any modern 3D graphics card, but we recommend an NVIDIA GeForce 6800 XT or better. At this time the DirectX Visualizer has only been tested on Microsoft Windows XP Professional SP2. 01 April 2009 6 of 26 ©2005-2009 Philips Electronics Nederland B.V.

    An example of this process is included in appendix A and includes more details on steps 3 and 4 in particular. The native resolution for a 20” 3D display is 1600x1200, for the 42” it is 1920x1080. 01 April 2009 ©2005-2009 Philips Electronics Nederland B.V. 7 of 26...

    . The first thing to do is to determine where to put this DLL. In most cases the directory containing the executable of the application is the right location. Copy over the Visualizer DLL from where it was installed (usually C:\Program Files\Philips\DirectX Visualizer) to the directory with the application’s executable.

    Visualizer can change the resolution back. This method is not preferred and should only be used as a last resort. Set the settings below to 0 to disable resolution switching. 01 April 2009 10 of 26 ©2005-2009 Philips Electronics Nederland B.V.

  • Page 11: Hardware Gamma

    Follow the instructions in section 6.9 to get a correct perspective. If straight lines toward the horizon still appear bent when looking at the 3D display from a different angle, then this could very well be caused by hardware gamma. 01 April 2009 ©2005-2009 Philips Electronics Nederland B.V. 11 of 26...

    Since there is no warning about switching back to the inverse projection matrix, this means that the approximation is active for the duration of the game and FarNearRatio will need to be tuned to get a proper depth impression (see 6.12). 01 April 2009 22 of 26 ©2005-2009 Philips Electronics Nederland B.V.
