## Dotted-Line Decorator for EaselJS

I’ve modified the line decorator demo with a preview of a dotted-line decorator. This line decorator draws solid circles with a fixed radius and spacing along the line between two points. Once the CompGeoJS quad. Bezier…

## EaselJS Line Decorator

One of the interesting features of the Flex Freehand Drawing Library was a rich set of line decorators.  These modules worked in tandem with a drawing engine to allow a wide variety of geometric objects to…

## CompGeoJS Parametric Line

I’ve been traveling on business the last two months, so little time has been available to work on the CompGeoJS project.  A recent break in the routine gave me an opportunity to begin work on parametric…

## Interactive 2D Graph Slice Tool

In order to interactively demonstrate certain geometric concepts such as y-at-x, x-at-y, or parameter value at a particular point on a curve, it is necessary to quickly scan lines of constant-x or constant-y value on a…

## Interactive 2D Graph Marker

I need a few tools on top of CompGeJS in order to create intuitive, interactive demos for planar curves and other graph features. The most commonly used tool will be an interactive, 2D graph marker, or…

## CompGeoJS 2D Graph Axes and Grid

I’ve enjoyed an opportunity to enhane the graphing tools in GompGeoJS.  Having a good baseline graphing capability is very useful for many of the demos that are to come, especially parametric curves. The CompGeoJS GraphAxis class…

## Architectural Sections in CompGeoJS

I want CompGeoJS to be useful to devs working on architectural applications, floor planning, and 2D layout, so I’ve added support for some simple drafting shapes, namely C-secitons, L-sections, and I-sections.  These are fundamentally simple polygonal…

## CompGeoJS Star Shape

I just added a Star shape to the CompGeoJS library that can be defined by the usual bounding rectangle and two additional parameters. A Star shape is typically defined by a number of points that are…
