The Blender Foundation (which freely distributes the software and takes care of the promotion of the new released versions of the Blender) and its projects at blender.org are committed to keeping Blender free of charge. Blender software is multifunctional software based on Python programming language. According to the information provided on the official website of the software, it includes the following features: rendering, modeling, sculpting, animation & rigging, story artist, VFX, simulation, pipeline, video editing, scripting and customize interface. Through the software it is possible to create geometric meshes, curves and surface directly in the three-dimensional digital space. The polygonal-mesh geometry consists of faces, vertices and edges. Due to the high efficiency of the obtained three-dimensional polygonal mesh of the developed 3D models, Blender is used for both conventional and parametric modeling, through the main functionalities of the software and through additional specialized add-on applications. This became the main basis for the application of software for the development of 3D bioengineering and ergonomic models.
For the needs of healthcare, high-quality add-ons in the following areas are available for use completely free of charge:
