A
DotBSplineInterpolator
is an interpolator
that creates a PolyBezier
geometry corresponding to a
single B-spline. It expects that the start, end, and control points of the
Connection
it routes correspond to what can be specified through the
'pos' attribute of the edges within Graphviz DOT as follows (if multiple
splines are specified through the 'pos' attribute, they have to be
represented through multiple connections).
The DotBSplineInterpolator
expects that the connection's
control points
represent control points
of connected cubic Bézier segments in the form 'p, (p, p, p)+'. In case the
start point equals the first control point, or the end point equals the last
control point, they are ignored when constructing the B-spline. In case this
is not the case, linear segments are added from the start point to the first
control point and from the last control point to the end point, respectively.
