I solved this intersection of points using this link http://paulbourke.net/geometry/2circle/ <http://paulbourke.net/geometry/2circle/> Here is my workspace code |b b1 r r1 r2 d d1| b1:= CircleAnimeMorph new. b1 center: 100@100. b1 openInWorld. b:= CircleAnimeMorph new. b openInWorld. d:= b1 center dist: b center. "distance between 2 circles" r:=b1 bounds width /2. "radius of first circle" r1:=b bounds width/2. "radius of second Circle" r2:=r + r1 . (d )< (r2) ifTrue: [| a h mid c c1 myPen h1 h2 mx my mc mc1| a := (r squared - r1 squared + d squared) / (2 * d). h := (r squared - a squared) sqrt. h1:= b center y - b1 center y. h2:= b center x - b1 center x. mx:=a * (b center x - b1 center x)/d. my:=a* (b center y - b1 center y)/d. mid := ((mx)+(b1 center x) @ (b1 center y )+(my) ) " calculates mid point between 2 intersecting circles (p2)" { mc:=(h * h1)/d. mc1:=(h * h2)/d. c:=(mid x + mc )@ (mid y - mc1 )."Actual Intersecting points" c1:=(mid x -mc) @ (mid y + mc1 )."Actual Intersecting points" Transcript show: (c); show: (c1); cr}. myPen := Pen new. myPen color: Color red. myPen putDotOfDiameter: 5 at: mid. myPen putDotOfDiameter: 5 at: c1. myPen putDotOfDiameter: 5 at: c.]. Can any one help me make this a methods ,I wanna make this a intersection method which will do all this when i say b1 intersection:b. should do all of this and draw colored dots at intersecting points -- View this message in context: http://forum.world.st/Get-the-point-of-Intersection-for-Morphs-tp4646066p464...
