drawmatrix polygon ?
Feb 08 2006 | 4:31 pm
hello ,
i`m trying to draw multi points polygon using matrix and .gl.sketch,
as you can see on attached images drawing using line_loop gives
other output than using polygon ,
does it have something to do with order of points in the list?
from the other hand i used jit.lcd before with the same format and
everything was fine,
but i run out of points (i need more than 128)
hopefully i`m missing something obvious, will be grateful for any ideas.
thanks,
wojciech

We hope to expose closed curves at some point, but for now, you need to do this yourself--i.e. break your polygon into chunks which are convex. I'll try to find time to make a JS example of taking a list of points that make up a polygon and breaking it into convex chunks.-Joshua
