Blender is a free, open-source tool for creating and animating 3D content. It is available for all major operating systems. It allows the creation and modification of graphics primitives, surfaces, etc. along with lighting and dynamic camera features. Animating is done via keyframes, and most properties can be animated over time. Advanced features include interactivity (e.g., game-like features), particle systems, skeleton-based models. Blender includes and is partially based upon a Python scripting system.

Data Analysis

Blender is a powerful program! The learning curve is quite steep, but this is ameliorated by the wealth of good online tutorials, many in video format (e.g., on YouTube). There is a large and vibrant user community, which means that instruction is easy to find, on practically any topic of interest.

To take advantage of Blender, the user should have a 3-button mouse. It can be used otherwise (e.g., with a laptop one-button trackpad), but it is simpler with a 3-button mouse.
