K-3D

K-3D is open-source software for 3D modeling and animation on Linux. It is listed in the Graphics & Design category and is intended for artists working with three-dimensional content. Its interface follows the look and feel of the user’s platform, with a consistent structure intended to be understandable to new artists and familiar to professionals.

The application combines flexible plugins with a node-based visualization pipeline. It supports procedural and parametric workflows, allowing properties to be adjusted interactively while results appear immediately. Selection can flow from one modifier to the next, and the pipeline allows different parts of a workflow to be connected in varied combinations.

K-3D includes an undo and redo system with an undo tree, allowing users to revisit earlier changes and move forward through available branches. Its workflow can mirror one side of a model and display the combined result as a subdivision surface in real time. The software also provides native RenderMan support integrated with its user interface.

On MirrorNest, the official build is mirrored directly on the catalog’s own storage and scanned for malware before publishing. The Linux platform makes this download relevant to users seeking open-source graphics and design software for that operating system. K-3D is no longer maintained by its developers, and this download is not an official release.
