RAMOS-BERMUDEZ, Pablo Enmanuel et al. Development of a new version of BioBlender, a Blender module for visualization of biomolecules. Rev cuba cienc informat [online]. 2021, vol.15, n.4, suppl.1, pp. 120-130.  Epub Dec 01, 2021. ISSN 2227-1899.

Biological macromolecules, such as proteins and nucleic acids, are the main engines of the living cell. Kno- wing their three-dimensional structure and the way in which they interact with each other and with the environment, contributes to understanding the functioning of the cellular machinery. Within scientific visualization, there is the art and science of 3D animation, a technique used by various programs, such as the open source 3D modeling software Blender. Precisely, on the basis of this, the BioBlender software package was developed, a Blender module that allows the intuitive representation of surface properties of biomolecules, showing their surface in a photorealistic way, thus allowing the visualization of complex properties such as electrostatic potential and the molecular lipophilic potential. BioBlender was developed and maintained by the Scientific Visualization Unit of the National Research Council of Italy, for an already expired version of Blender, so it is necessary to develop a new version that integrates with the current changes in Blender, constituting the objective of the investigation. For this, use has been made of models extracted from the Protein Data Bank biological database, development tools such as the PyCharm integrated development environment and the exclusive use of the Python programming language with scientific libraries such as Numpy, Scipy and Prody. Despite significant advances, work is still ongoing, developing new methods and techniques to construct a reasonable sequence of movement for proteins.
