class CircleAntiPodal
constructors: |
|
---|---|
returns: | the point on the diameter of the circle cut by the line of given point and the circle center, and opposite to the point of the diameter nearest the given point. |
conditions: | point and circle are coplanar; point not circle center |
else returns: | None ; None |

class SphereAntiPodal
constructors: |
|
---|---|
returns: | the point on the diameter of the sphere cut by the line of given point and the sphere center, and opposite to the point of the diameter nearest the given point. |
conditions: | point not sphere center |
else returns: | None |

class SegPoint
constructors: |
|
---|---|
returns: | the endpoint of the line segment (the line 'p1' or 'p2' attributes) farthest from the given point. returns line.p1, line.p2 respectively with use of keyword seg = BEGIN or seg = END. |
note: | a pygeo line can be treated as either infinite in length, or in this context, as the segment between its 'p1' and 'p2' attributes. |
