Edge

SameParameter

For a given point t on the edge, we compare the 3d coordinates of that parameter t for all the curves associated with that edge.

(1)
\begin{equation} x_1 = c_1(t), x_2 = c_2(t), ... \end{equation}

The SameParameter criterion is fulfilled, if all the coordinates x coincide within the edge's tolerance
