It might be not a really important bug, but still: In "SimpleGL" SDK sample Radeon flag waves along Y-axis. It seems that it's not the behaviour the developer expected. To make it visible I've just swapped "v" and "w" in kernel - now it waves along "Z" and looks much better. By the way (sorry, I'm newbie here) - is there some OpenCL GCN-optimization guide or any possible recommendations for the new HD7970/HD7990 chips, one of which I'm planning to buy and program?

you can rotate it with mouse. and there are some optimization tips in OpenCL programing guide from AMD.

My mouse doesn't work in this window - how can I get rotations? I've started prebuilt SimpleGL.exe on Windows 7 x64.

P.S. As I've found out, SimpleGL.cpp missed something like this:

case WM_LBUTTONUP:
     mouseButtons = 0;
     return 0;
case WM_LBUTTONDOWN:
     mouseOldX = LOWORD(lParam);
     mouseOldY = HIWORD(lParam);
     mouseButtons = 1;
     return 0;
case WM_MOUSEMOVE:
     int x,y;
     x = LOWORD(lParam);
     y = HIWORD(lParam);
     int dx, dy;
     dx = x - mouseOldX;
     dy = y - mouseOldY;
     if (mouseButtons) 
     {
          rotateX += static_cast<float>(dy * 0.2);
          rotateY += static_cast<float>(dx * 0.2);
     }
     mouseOldX = x; 
     mouseOldY = y;
     return 0;

just before "case WM_KEYDOWN"

to bring mouse to life in windows.

To SDK developers: Guys! add this, please, in the next SDK version! And make, please, VolumeRendering sample little more up to date - compiler dislikes some deprecated functions. It's great sample, but there are also problems with other samples integration.
