Rounded Rectangle Button Class (Read 2561 times)

danielt YaBB Newbies Offline Posts: 36 South Australia	Rounded Rectangle Button Class Oct 7^th, 2009, 5:57pm Not sure if this already exists. But Here's a variation of the button class example in the Processing Handbook by Casey Reas and Ben Fry. I love this book! So easy to read and understand. http://www.openprocessing.org/visuals/?visualID=5099 Cheers!

OSX 10.4.11, Java 1.5, Firefox 2.0. On close inspection it looks like an aliasing issue. (Try noSmooth() ?) --Ben

Isn't that something you usually see when using one of the 3D renderers with smooth()? Slightly unusual to see it here, perhaps related to graphics card? An alternative solution might be to draw the rounded rounded rectangle as a solid shape (i.e. calculate appropriate vertices to generate it) rather than as a composite of several shapes, since the lines clearly appear at the borders of the shapes...

For what it's worth it looks fine on my machine, but it's currently in power-saving mode so using the integrated Intel graphics chip...

Where is the what if the what is in why?

I'm on windows with Firefox 3.0.14 and java 6 build 1.6.0_15b03 and it works fine. I'm curious if anyone else is having the same issues and if they wouldn't mind downloading and running from the IDE. I'm curious if it's browser related?

Thanks for feedback anyway guys. You're probably right blindfish about doing it as a solid shape.

Maybe I'll try a similar approach when I get some time to explore it again. http://demonstrations.wolfram.com/BezierCurveApproximationOfAnArc/
