Blender - Your FOSS 3D Software


Table of Contents

If you are into game development, video editing, or 3D modeling as a professional or a hobby, then Blender is a tool you should definitely look at. Blender is a FOSS solution/alternative to many commercial tools that are available and it is able to strongly match most of these commercial tools.

Blender is a cross-platform application which means you can not only run it on Linux but also on Windows and macOS. Blender is well suited to individuals and small studios who benefit from its unified pipeline and responsive development process. It supports the entirety of the 3D pipeline, anything from modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing, and game creation.

Final Thoughts

As a community-driven project, the public is empowered to make small and large changes to the code base, which leads to new features, responsive bug fixes, and better usability. Blender’s user manual is available online in several languages and is constantly updated by a worldwide collaboration of volunteers every day. Check out this link to a large collection of free tutorials and demo files to get started with Blender and to explore the more advanced Blender features. Blender Institute also provides extensive training materials in the e-Store (books, DVDs) and on the Blender Cloud.  


If you are a 3D artist in need of either one or more of these 3D development tools or features, you should definitely check out blender. You will find that all the standard tools you’ve come to expect will all be available. Professionals will jump right in as they would find things much like they have come to expect. If you are a newbie, getting started can be a bit intimidating with the interface and the plugins but that can be mastered quite easily. Blender has no price tag, but you can invest, participate, and help to advance a powerful collaborative tool: Blender is your own 3D software.Share your thoughts on Blender with us in the comments.
