K-3D Portable is intuitive, consistent, and discoverable. K-3D features procedural and parametric workflows. Properties can be adjusted interactively and results appear immediately. The powerful, node-based visualization pipeline allows more possibilities than traditional modifier stacks or histories. Selection flows from one modifier to the next. An advanced undo and redo system ensures you can always go back, and the pioneering undo tree means you can always go forward, even where other programs lose the ability to redo. Industrial-strength standards form the foundation on which K-3D builds - including native RenderMan(TM) support that integrates tightly with the K-3D user interface.
