Intro to BioBlender by Ashley LeeBlender is being used for scientific visualization, one of the first projects was BioBlender. With BioBlender scientists can load protein databank files and render animations for visualization. See Intuitive representation of surface properties of biomolecules using BioBlender by Andrei et al. BMC Bioinformatics 2012 here.

Blender is ideal for data visualization because of its powerful rendering features like: volumetric materials, point clouds, smoke and fluid dynamics, and fast GPU rendering. Reza Fatahi on the BF-Python mailing list is interested in using Blender to automate rendering of confocal microscopy files. Blender can also import data from Paraview.
