## Recent Data Visualization Work

Wow! I woke up and realized it’s almost Thanksgiving and I have not posted anything all summer and most of the fall. I’ve been in kind of a development black hole and spending a lot of…

The CompGeoJS package is intended to be an open-source resource for web developers to learn and apply principles from numerical analysis and basic computational geometry. Clients sometimes do not wish to have applications developed using open-source…

As I alluded to in the prior post, it is necessary to temporarily alter the direction of the CompGeoJS project to suit some near-term requirements, particularly in the area of data visualization and analysis. I will…

I just released a preliminary version of the CompGeJS quadratic Bezier. This version has all the y-at-x, x-at-y, x-at-t, length-at-t, and similar methods with full arc-length parameterization. I have not, however, implemented getX() and getY() queries…

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…

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…

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…

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…
