polygons over vertices: V (n, 3), the faces as ptr/idx (face k is idx[ptr[k]:ptr[k+1]]), a colour per face (m, 3) in [0, 1] or one colour for all, the face and edge transparency

Input

V array of vertex coordinates with shape (n, 3)
ptr face offsets of length numFaces+1 into idx
idx concatenated zero-based polygon vertex indices
faceColor one RGB triplet or one triplet per face
faceAlpha face opacity from 0 to 1; default 1
edgeColor edge colour; None or ‘none’ hides edges
edgeAlpha edge opacity from 0 to 1; default 1
lineWidth edge width; default 0.5
values optional scalar face values for the colour bar
colormap optional colour map associated with values
colorRange optional colour-bar range

Members

bounds the corners (lo, hi) of the box around the vertices
edges the edges of the polygons, every one once, (e, 2)
numCorners the number of corners of every face
triangles the fan triangles of the faces, (k, 3), and the face each belongs to
