GEOintersectCircleArc

Top Previous Next

Cut of circle with arc.

The arc runs against the clockwise of the start to the final corner. If both corners are same, it also concerns a circle. Not required result parametres may be a ZERO.

Parametre

cx1 (const stands in) [IN]

cy1 (const stands in) [IN]

Centre of the circle.

r1 (const stands in) [IN]

Radius of the circle.

cx2 (const stands in) [IN]

cy2 (const stands in) [IN]

Centre of the arc.

r2 (const stands in) [IN]

Radius of the arc.

alpha (const stands in) [IN]

Start corner of the arc runs against the clockwise to the final corner.

beta (const stands in) [IN]

Final corner.

sx1 (stands in *) [IN / OUT]

sy1 (stands in *) [IN / OUT]

Co-ordinates of the first intersection.

sx2 (stands in *) [IN / OUT]

sy2 (stands in *) [IN / OUT]

Co-ordinates of the second intersection.

Result

(int) [OUT]

If becomes–2 zurückgeliefert the centres and the radii are same. If becomes–1 zurückgeliefert, the centres are same. But the number of the intersections.
