In my last post I talked about doing a peer-review on bezierTangent(). I talked about not being able to find Dliu53 tests but after another look I found them. Take a look at his bezierTangent() test. At first glance it looked good and it made me question by review decision. But after recreating the test and taking a closer look I am sticking to the status of review-needs-work. I decided to use the same code from Dliu53 test in Processing Java 1.0.7 environment. Here is a screen shot of the two results side-by-side.
If you look closely, the orange lines are not being drawn in the exact same location. The lines are being drawn using the results from bezierPoint() andbezierTangent(). Check out my test.
