Jot

A software package that enables artists to annotate 3D geometry with stroke-based non-photorealistic rendering (NPR) effects by drawing directly into the scene. Complex stylizations that would be tedious to animate by hand are automatically rendered with coherence during real-time interactive animation.

Details
Jot is comprised of the algorithms and interfaces presented in the WNPR and CSS papers, as well as my thesis. It is a research prototype, rather than a production-grade tool. Nevertheless, we make this software available to demonstrate how aesthetic flexibility, and artist accessibility increase substantially when hands-on controls replace the more traditional knobs and sliders of existing stylized rendering systems.

Results
Via a tablet interface, the Jot framework enables the designer to leverage existing skills with traditional media to directly impart a personalized aesthetic. By preserving the user's annotations automatically, the system frees the artist to explore stylizations too rich to animate by hand via traditional means. Some example images and animations from Jot can be found in the videos, stills and PDFs on the WNPR, CSS, thesis, and gallery pages.
