Christoffer, Ensight format - You can volume render multi-block datasets by first using the Merge Blocks filter.

Hello What are your thoughts on the best file format to use when doing volume rendering in ParaView? I have been trying out the ensight format and the vtk format and find them less then ideal, is there anything better? Findings for ensight: ParaView does not appear to support volume rendering of ensight files due to it not supporting volume rendering of multi-block datasets and the ensight reader always imports things in multi block mode. There are ways to get around this (tetrahedralize together with calculator filter) but the end results appear to be extremely slow when volume rendering. Findings for vtk: Importing a volume of data as image data and volume rendering it works well but image data in the vtk format must always be aligned to the global orthogonal (x, y, z) axes so it cannot be rotated. Since we have multiple data files that all must be positioned and rotated in a scene (MRI volumes and image planes) this makes things uncomfortable. There is a transform filter in ParaView but after applying it to image data it changes the data type to curvalinear grid which ParaView cannot volume render. What are the alternatives?
