What EQUINOX-3D is

EQUINOX-3D is a desktop application for 3D modeling, animation, rendering, VR content creation, CAD/CAM, 3D printing and laser cutting. It is available for Linux and macOS, with downloads for Linux x86 64-bit, Intel Mac and Apple silicon Mac. Its tools include parametric and subdivision surface modeling, animation, and a built-in renderer. Ray-traced windows let users work with models while selecting objects and adjusting lights and materials. Rendering features include multi-threading, global illumination, depth of field, motion blur and caustics; the software also supports Cg and GLSL shaders. A plugin manager can change, recompile and reload plugins without restarting. The native .eqx format is open, and complete source code for loading and saving it is provided. Linux and Mac packages can be extracted and run without installation. Mac users must first install and start XQuartz. The free shareware plan permits commercial and non-commercial use and installation on any number of computers, provided author information remains intact.
