Thank you Mathieu for your reply. Regarding point 2 I have few questions: 1. I see the volume rendering mode (which I can switch between smart and CPU based) when I select a wavelet for instance. However, I can't see it when I choose unstructured cell type as the source (and this applies to my data set coming from CFD results). In that latter case, I get the select mapper drop down menu which has the options of projected tetra/z sweep/bunyk ray cast/resample to image. Is there a way to ensure volume rendering is done using the GPUs in that case? 2. In the case described above, when I select resample to image, the color of the model gets messed up (it becomes one color). Is there a way to get it back to normal? Thanks.
