[vtkusers] about the vtkGPUVolumeRayCastMapper

[Jochen K.]

Yeah,

I got it.

Here's the output of TestGPUInfo for my graphics card:
There is 2 GPU(s).
 GPU 0:
  dedicated VRAM=466 MB
  dedicated RAM=0 MB
  shared RAM=1274 MB
 GPU 1:
  dedicated VRAM=466 MB
  dedicated RAM=0 MB
  shared RAM=1274 MB

----------------------------------------------------------
Step by step instructions:
----------------------------------------------------------
1. Install DirectX SDK June 2010

2. Install Microsoft SDK 7.1 or 7.0A

3. CMake:
3.1: after the first Configure verify the following vars are set properly:
DirectX_INCLUDE_DIR: C:/Program Files/Microsoft DirectX SDK (June
2010)/Include
DirectX_LIBRARY: C:/Program Files/Microsoft DirectX SDK (June
2010)/Lib/x86/d3d9.lib
(these two entries usually wil be found automatically)
don't forget to enable BUILD_SHARED_LIBS and BUILD_TESTING !!

3.2. Configure and Generate.

4. Open VTK.sln in Visual Studio.

5. Add the following path to your vtkRenderer.csproj:
C:\Program Files\Microsoft SDKs\Windows\v7.1\Include
(Please see my P.S. at the end of this post)

Due to the fact that I'm still a CMake noobie I added this path directly in
Viusal Studio:
5.1 in the solution explorer right click on project vtkRenderer, 
5.2 choose Properties
5.3 click  Treenode C/C++ General  and add "C:\Program Files\Microsoft
SDKs\Windows\v7.1\Include" to the "Additional Include Directories"

6. Select release, debug or relwithdebinfo under your solution configuration
and build all.

7. Get a cup of coffee or tea ;-)

8. When everything was build successfully goto your build directory and
browse to your bin/debug, bin/release or bin/relwithdebinfo folder, open a
cmd-Window, run RenderingCxxTests.exe and select test No. 14 and watch the
output.


So far so good.
Hope that helps you to get DirectX support in VTK.

with kind regards
Jochen


P.S.: It would be very nice if someone could tell we where/how to add the
path "C:\Program Files\Microsoft SDKs\Windows\v7.1\Include" in Cmake in
order to make vtkRenderer.vcproj finding ddraw.h.
