transform(matrix)

Transform mesh vertices by a matrix.

Parameters:matrix (float array of 16 items in [-inf, inf]) – Matrix.

calc_normals()

Calculate vertex normals.

update(calc_edges=False)

update

Parameters:calc_edges (boolean, (optional)) – Calculate Edges, Force recalculation of edges.

validate(verbose=False)

validate geometry, return True when the mesh has had invalid geometry corrected/removed.

Parameters:verbose (boolean, (optional)) – Verbose, Output information about the errors found Returns:Result Return type:boolean

edge_loops_from_edges(edges=None)

Edge loops defined by edges

Takes me.edges or a list of edges and returns the edge loops

return a list of vertex indices. [ [1, 6, 7, 2], ...]

closed loops have matching start and end values.

edge_loops_from_faces(faces=None, seams=())

Edge loops defined by faces

Takes me.faces or a list of faces and returns the edge loops These edge loops are the edges that sit between quads, so they dont touch 1 quad, note: not connected will make 2 edge loops, both only containing 2 edges.

return a list of edge key lists [ [(0,1), (4, 8), (3,8)], ...]

return a list of edge vertex index lists

from_pydata(vertices, edges, faces)

Make a mesh from a list of verts/edges/faces Until we have a nicer way to make geometry, use this.

Parameters:

• vertices (iterable object) – float triplets each representing (X, Y, Z) eg: [(0.0, 1.0, 0.5), ...].
• edges (iterable object) – int pairs, each pair contains two indices to the vertices argument. eg: [(1, 2), ...]
• faces (iterable object) – iterator of faces, each faces contains three or four indices to the vertices argument. eg: [(5, 6, 8, 9), (1, 2, 3), ...]
