Blender for biology The making of Protein Expressions – Study N 2

We presented in 2008 the initial steps of our project, to use Blender for scientific representation and molecular animation of life at the cellular level. This report will focus on some developments in two major aspects: the use of Blender Game Engine in conjunction with other scientific programs to elaborate the movement of proteins and the development of a visual code based on texturing and particles special effects to represent the physical and chemical properties that confer to molecules an appearance that reveal useful information. We also describe some details of the construction of specific scenes.
