Thanks a lot guys will now check your parches. and let you know!!!

Hello,

The curve is not really smoothed (you can add more vertices if you want). I can't see another possibility here, if you want only one form working with [draw_line] and [draw_fill] (and if the angle of your slice is > 180° because you will get a concave form). Maybe it can help you. ++

Hi guys

...

im trying to make a 2D pizza slice like shape using GEM. I want to control the angle of the slice mantaining the roundness of its extenal shape.

I have tried using [curve] but have had no luck when altering the angle. I have tried basic math and trigonometry to assign the values of the different points, but had no luck cause the intersections between the sides and the external border get rounded up. It seems to me that [curve] is not the right object to use. Specifically i have been using the object [curve] with 5 points but have not managed. I want to make a solid shape, not just the outline.

thanks

It does some really nice stuff if you add a high-speed counter to it:

Guys thanks again. PizzaSlice.pd works great for me. Yummy

If you are not part of the solution, you are part of the problem.

hey,

I was thinking about how to do a graphic "knob" with this patch, but could not realize yet the correct trigonometric operation to do with [gemouse] transformations... Could someone give an idea? I though in something like the edge of the angle stucked in the mouse pointer, but I don't know Gem or geometry enough to realize it...

the starting point is attached...

thanks glerm

Maybe this… (but i'm not sure ! :) For Andrew Faraday : Can you post your funny patch on this list ? ;) ++

well,

I made something that works... but I am curious about best
solutions...
