This problem, in a couple different variations, has been presented to me a few times over the past two months so I thought it might be worth a blog post.  The problem ranges from drawing an aribtrary...

My recent two hitting sessions were against a heavy, cold wind.  I was quite pleased with how the frame held up against the wind.  Here are some pics of the racquet, courtesy of Tom Coyle (Hilton D/...

This is the first in a multi-part review of the Prince EXO3 Black.  I’ve hit with this racquet four times with my standard stringbed of Pro Hurricane Tour 17 on the mains and VS Team Gut 17 on ...

I can’t believe I have a new racquet.  I’ve been hitting with the O3 Speedport Black Team while recovering from a shoulder injury.  For some time, I have wanted to upgrade to a heavier, ...

Just returned from a long business trip.  I’ve started a new and pretty intense gig.  I’m back to work with the Flex framework for the first time in two years and already doing Google Fi...

The Degrafa Cardinal spline is now available from the Origin branch.  Usage is very similar to the Catmull-Rom spline with the exception of the tension parameter.  The Cardinal spline is based on th...

There is not much difference from the demo of the Bezier x-at-y method from the previously posted y-at-x demos.  Here is the MXML for the test case.  Most of the heavy lifting is in the displayXatY(...

A few requests for the algorithm behind the Bezier y-at-x and x-at-y methods have been received.  The code is self-contained in the com.degrafa.geometry.AdvancedQuadraticBezier and AdvancedCubicBezie...

I have received a couple requests for x-at-y methods in the advanced quadratic and cubic Bezier classes to complement the existing y-at-x methods.  Fortunately, the algorithm is the same, just a diff...

Continuing from part 4 of this series, we are looking at tension values outside the range of zero to one. When T is negative, then s = (1-T)/2 increases from 1/2 and grows without limit as T becomes ...
