Blender is a 3D computer graphics software tool. It is open-source and free to use. Blender offers tools for 3D modeling, texturing, skinning, rigging, raster graphics editing, UV unwrapping, and other 3D animation functions. The program can integrate with a range of external render engines through add-ons and plugins. It uses the Python programming language, and users can create custom tools, automation, or game logic for Blender using Python. Developers use Blender to create animated films, virtual reality (VR) applications, computer games, and video games. You can also use Blender to produce visual effects for film and video projects and craft 3D printed models. The tool performs modeling, simulation, animation, rendering, and post-production tasks.
