Open-source Spline alternatives

This entry is the official GitHub mirror of Blender, the free and open-source 3D creation suite. Blender covers the whole 3D pipeline in one application, from modeling and rigging through animation and simulation to rendering, compositing, motion tracking and video editing.

Artists and studios use it to produce models, animations and rendered images, and it is written mainly in C++. Project resources include a reference manual, a user community, a developer forum, build instructions, and a code review and bug tracker hosted on the project's own development site rather than on GitHub.

Blender as a whole is licensed under the GNU General Public License version 3, and individual files may carry a different but compatible license. It is a desktop application installed locally, so there is no hosted edition to sign up for.

Three Editor is a low-code editor built on Three.js for creating 3D scenes, including digital twin and industrial control visualizations. The README is written in Chinese and presents the project as a customizable, component-based editor with an online preview, an examples page and documentation, all hosted on GitHub Pages. It is aimed at front-end developers who want to assemble 3D scenes without writing every line of Three.js code.

The editor core is published on npm as three-editor-cores, and its source is available separately. The repository is organized around an editor page, an example page, sample code and an online code runner based on CodeMirror. To connect your own local assets, the file layout must match the public files folder and be set in the editor configuration. The author also points to a newer, more capable editor and to a large collection of native Three.js and Cesium examples.

The project is built with Vue 3 and Vite on Node 18 or later, and it uses dat.gui and GSAP according to its topics. It is released under the Mulan PSL v2 license. Because the maintainer says that most of their open-source time now goes to the examples repository, check recent activity before depending on this version.
