<static> getQuadFromPoints(pt1,, eraserRadius)

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

Returns:

• A vector that contains at most two points of intersection

---

<static> splitInkListBetween(inklist, splitpoint, inklistpos)

This function will split the specified inklist by the specified point. The specified point will remain on the old inklist and the new inklist will be added to the end of the inklist array.

Parameters:

Name	Type	Description
inklist		the array of inklist arrays.
splitpoint		the point within the array to split the list by
inklistpos		the position within the inklist array.

Returns:

the newly created array
