3 Point Arc

Functionality

Given a start coordinate, a through coordinate, and an end coordinate this Node will find the Arc that passes through those points.

Inputs

• arc_pts input is [begin, mid, end, begin, mid, end, begin, mid, end….. ]

  • must be (len % 3 == 0 )

• Num Verts is either

  • constant

  • unique

  • or repeats last value if the number of arcs exceeds the number of values in the Num Verts list

Parameters

The UI is quite minimal.

• Num Verts can be changed via Slider input on the UI or as described above, it can be fed multiple values through the input sockets.

Output

• (verts, edges) : A set of each of these that correspond with a packet of commands like ‘start, through, end, num_verts’

• verts needs to be connected to get output

• edges is optional
