"This example uses 3.\n"
" - The amount of nodes between the corner points need to be equal for the guiding surface. This "
"is the same as for normal 3 sided faces, just now one side is created of multiple edges, for which "
"the nodes are added up."
" - In the example each edge has the same length, hence nodes. As each side of the transfinite surfce "

"We then need to ensure the same node count for the guiding surfaces. This is done with transfinite curves\n\n"
" - The node count of a transfinit curve describes the number of nodes per selected edge. The edge nodes"
"include the ones for starting and ending vertex\n"
" - If two transfinite edges that share a vertex, this vertex is doubled and one node is dropped.\n"
" - Therefore, the total node count of N connected edges is (N x Node - N). This needs to be considerd "
"when setting the transfinite curve node number\n"
" - For our example: Side 1: 13 Nodes/Edge per edge (1*13-1=12), Side 2: 5 Nodes/Edge (3*5-3=12), Side 3: 7 Nodes/Edge (2*7-2=12) "
