Blender
Blender is a free and open-source 3D computer graphics software used for creating animated films, visual effects, art, 3D printed models, motion graphics, interactive 3D applications, and virtual reality. It supports the entire 3D pipeline, including modeling, rigging, animation, simulation, rendering, compositing, and motion tracking. Developed by the Blender Foundation, it is widely used by professionals and hobbyists for its comprehensive feature set and active community.
Developers should learn Blender when working on projects involving 3D graphics, such as game development, architectural visualization, or film production, as it provides a robust toolset for asset creation and animation. It is particularly valuable for indie developers or small teams due to its cost-effectiveness and integration with game engines like Unity and Unreal Engine. Additionally, its Python API allows for automation and custom tool development, making it useful for technical artists and pipeline engineers.
