This function constructs a rectangle around point P1P2 with width the rectangle will be tilted the same angle as the P1P2 B________A | P1 | | | | | | | | | | |P2| C D

Parameters:
Name Type Description
pt1,

pt2 - the endpoints of the quad

eraserRadius

The radius to expand the quad with

Returns:

the QuadPoint


<static> isPointInQuad(qp, testpt)

This function will return true if the specified point testpt is in the quad

Parameters:
Name Type Description
qp

the quadpoint to check within.

testpt

Point to check for

Returns:
  • A bool indicating if the point is in the quad

<static> returnPointThatIntersectsQuad(qp, pt1,)

This function will return the specific points that intersect the given quad and the line segment. Note that if there are two points of intersections, the closest point to pt1 will be the first point in the vector.

Parameters:
Name Type Description
qp

the quadpoint to check within.

pt1,

pt2 - Points that define the line segment to check against the quad
