anglePoint

Calculate coordinates at specific angle and distance.

Description

A function calculating the coordinates of the point that is at a specific radian angle in a specific distance from a source point. Internally called by smoothArc.

Usage

anglePoint(A, angl, len)

Arguments

`A`	Vector of length two with the coordinates of the source point.
`angl`	Radian angle indicating into which direction the new point is to be calculated.
`len`	The distance at which the new point is situated from the source point.

Value

A vector of length two with the coordinates of the new point.

Note

Another pretty superfluous helper function...
