Hello, I've installed PV 4.3 on a few PCs, all of them running Win 7 64-bit. What I've found is that volume rendering, curiously, works on some of them and fails on others. The error messages I got look like this: ========================================= ERROR: In C:\DBD\pvs-x64\paraview\src\paraview\VTK\Rendering\VolumeOpenGL\vtkOpenGLProjectedTetrahedraMapper.cxx, line 188
vtkOpenGLProjectedTetrahedraMapper (0000000013AB80B0): The required extensions are not supported. Warning: In C:\DBD\pvs-x64\paraview\src\paraview\VTK\Rendering\OpenGL\vtkOpenGLExtensionManager.cxx, line 781 vtkOpenGLExtensionManager (0000000013567D60): Attempting to load GL_ARB_multitexture, which is not supported. ERROR: In C:\DBD\pvs-x64\paraview\src\paraview\VTK\Rendering\OpenGL\vtkOpenGLExtensionManager.cxx, line 787 vtkOpenGLExtensionManager (0000000013567D60): Extension GL_ARB_multitexture could not be loaded. =============================================== This seems to only happen to the relatively old PCs (~ 4 or 5 years old). For example one of them has graphics card of ATI Radeon HD 3450 (Microsoft Corporation WDDM 1.1), driver version 7.14.10.0018; another laptop has Intel HD graphics, driver version 8.15.10.2559. - I'm wondering if these are considered insufficient for volume rendering to work with PV 4.3. More curiously, volume rendering seems to run OK with PV 4.2 on these machines. Thanks, -Ruq
