README
Wet & Sticky The Chalk Wet & Sticky module is derived from the seminal dissertation "Wet & Stick: A Novel Model for Computer-Based Painting" by Malcom Tunde Cockshott, and the implementation of that model by Tunde Cockshott, David England and Kevin Waite. The complete source code to the first implementation is included in the module_ws/ws and is released under the terms of the GPL. The W&S model is implemented in the following components: * A color strategy * A paint op * A filter The color strategy implements the canvas; the paint op implements the application of paint and the filter implements the paint simulation engine. This system adds the following interesting capabilities to Chalk: * Extending the tool options dialog with a widget describing the paint op. * Extending the paint op class with properties beyond opacity and color to a more generic structure with can contain the many different properties needed by more complex color models to calculate bitBlt's. All the ordinary paint ops still work, but they act as if they are applying dry, thin paint, conforming to Cockshott's analysis of the Shoup model (which Chalk implemented in the first instance) as a subset of the W&S model. * Adding continuously running filters (either in separate threads or called by a timer) to a particular paint device. * Adding a new way to mix colour; the older colour selection widgets still work, but only give completely dry, infinitely thin paint. * Creating a layer with a fill of 'substrate' cells -- i.e, filling not just with colour, but also with certain calculated amounts of height, gravity and absorbency.
