Great discussion started here
To answer some of the questions and to give more background:
- The grid resolution is 1x1cm. The problem starts when the distance of
the readings gets high. Then a 1° resolution doesn’t cover all cells anymore.
And cells get counted double on short distance

Thanks a lot for the links.
I don't need it to be drawn. I need the fields within the arc for some
statistical calculations for an occupancy map.
So the target is a 2D array, not a picture.

I think you shouldn't implement the algorithm directly. Rather look for a

Hi,
I wonder if someone can help me with a function I need for programming my robot.
I want to update an 2D occupancy grid based on sonar data. The sonar “view
angle” is cone shaped. So I need to calculate all cells of a 30° slice of a
filled circle.
Something like this: http://www.intechopen.co
