<div>
<p class="MsoNormal">Findings for ensight:<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">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.<u></u><u></u></p>

<div>
<p class="MsoNormal">Findings for vtk:<u></u><u></u></p>
</div>
<div>
<p class="MsoNormal">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.<u></u><u></u></p>
