The vtkOpenGLGPUVolumeRayCastMapper can't support ATI graphic card?
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
When i research the vtkOpenGLGPUVolumeRayCastMapper, the method "LoadExtensions(vtkRenderWindow *window)" is set not to support the ATI graphic card.
const char *gl_vendor=reinterpret_cast<const char *>(glGetString(GL_VENDOR)); if(strstr(gl_vendor,"ATI")!=0) { this->LoadExtensionsSucceeded=0; return; }
Why don't the class support it??
