rotate oval in lcd

June 27, 2009 | 3:42 pm

hey folks.

i’m making a gui and i want to put an ellipse in it. (see http://www.em411.com/blog/7385/0/vector_crossfade_wgui__maxmsp.html for a pic of the gui that i want to add an ellipse to, with an explanation of what the patch is for. the oval will define the path of an oscillator that scans through a landscape, basically).

The problem is that i can’t figure out how to make an ellipse where the axes aren’t just straight up and down. it seems like i will probably have to do some kind of hack using paintarc. it wouldn’t be as pretty (angles at the joints), and it would requite some annoying maths, but it would get the job done.

hmmm a diagonal oval … looks like something you
need to calculate point by point (using "lineto").

What you want to do would be a lot easier with Jitter.

yeah, it is a GL job.

just built on with nato after i didnt get the formula right for [lcd]. Smile

If you don’t have Jitter, try jsui, it can also talk openGL…

thanks, i’ll look into that. I’ll probably get jitter one of these days, but i’m stuck in max 4 until my financial situation changes.
