t = Slider(0, 1, 0.01, 1, 200) SetValue(t, 0.5) A = (0,0) B = (1, 0) s = Polygon(A, B, 4) C0 = Centroid(s) VC = Vertex(s, 3) VD = Vertex(s, 4) F = Point(Semicircle(VD, VC), t) CR = Centroid(Polygon(F, VC, 4)) CL = Centroid(Polygon(VD, F, 4)) dL = Length(Segment(VD, F)) dR = Length(Segment(VC, F)) side = Perimeter(s)/4 angR = Angle(F, VC, VD) angL = Angle(VC, VD, F) sR = Translate( Rotate( Dilate(s, dR/side, C0), -angR, C0), Vector(C0, CR) ) sL = Translate( Rotate( Dilate(s, dL/side, C0), angL, C0), Vector(C0, CL) ) Output = {sR, sL}
