For Cuis-Smalltalk, we built Morphic 3, the third design iteration of these ideas, after Self’s Morphic 1 and Squeak’s Morphic 2. If you already know Morphic in Self or Squeak, most concepts are similar, although with some improvements: Morphic 3 coordinates are not limited to being integer numbers, the apparent size (zoom level) of elements is not tied to pixel density, and all drawing is done with high quality (subpixel) anti aliasing. These enhancements are enabled by the huge advance in hardware resources since Self and Squeak were designed (in the late 80’s and late 90’s respectively). Additionally, careful design of the framework relieves Morph programmers from much the complexity that was required, especially with regards to geometry.
Vector Graphics is actually what got the Cuis project started. In 2003, ten years before the Retina display, I (Juan Vuletich) decided that making Morphic zoomeable and independent of pixel resolution would require completely abandoning back compatibility with the existing Morphic in Squeak. I took Squeak 3.7 and started working on what would later be named Cuis Smalltalk.
