To build a mesh, first you will have to determine its vertices.
You have to compute them in a comma separated list, with square brackets.
If you want to define 3 points, enter a list like the following :
[x1, y1, z1, w1], [x2, y2, z2, w2], [x3, y3, z3, w3]
Once the vertices list is complete, you have to set which points are linked.
To do so use a comma separated list of edges. An edge is defined by a list of points. Points are represented by their indexes in the previous list.
So if you want to link the three previous points, enter the following edges list :
[1, 2], [2, 3], [3, 1]
But if you want to optimize a bit, you can replace the previous list with this faster one:
[1, 2, 3, 1]
By default all edges are white, but an optionnal setting enables you to change the edges' colors.
If you want for example a red edge between 1 and 2, a blue between 2 and 3 and a green between 3 and 1, enter this list :
"red", "#FF0000", "#0f0"
The drawback of the optimized edges list is that you can assign only one color for an edge group.
