bpy_extras submodule (bpy_extras.mesh_utils)
- bpy_extras.mesh_utils.mesh_linked_uv_islands(mesh)
Returns lists of polygon indices connected by UV islands.
- Parameters
mesh (
bpy.types.Mesh) – the mesh used to group with.- Returns
list of lists containing polygon indices
- Return type
list
- bpy_extras.mesh_utils.mesh_linked_triangles(mesh)
Splits the mesh into connected triangles, use this for separating cubes from other mesh elements within 1 mesh datablock.
- Parameters
mesh (
bpy.types.Mesh) – the mesh used to group with.- Returns
lists of lists containing triangles.
- Return type
list
- bpy_extras.mesh_utils.edge_face_count_dict(mesh)
- Returns
dict of edge keys with their value set to the number of faces using each edge.
- Return type
dict
- bpy_extras.mesh_utils.edge_face_count(mesh)
- Returns
list face users for each item in mesh.edges.
- Return type
list
- bpy_extras.mesh_utils.edge_loops_from_edges(mesh, 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.
- bpy_extras.mesh_utils.ngon_tessellate(from_data, indices, fix_loops=True, debug_print=True)
Takes a polyline of indices (ngon) and returns a list of face index lists. Designed to be used for importers that need indices for an ngon to create from existing verts.
- Parameters
from_data (list or
bpy.types.Mesh) – either a mesh, or a list/tuple of vectors.indices (list) – a list of indices to use this list is the ordered closed polyline to fill, and can be a subset of the data given.
fix_loops (bool) – If this is enabled polylines that use loops to make multiple polylines are delt with correctly.
- bpy_extras.mesh_utils.triangle_random_points(num_points, loop_triangles)
Generates a list of random points over mesh loop triangles.
- Parameters
num_points – the number of random points to generate on each triangle.
loop_triangles (
bpy.types.MeshLoopTriangle, sequence) – list of the triangles to generate points on.
- Returns
list of random points over all triangles.
- Return type
list
