MeshLoop(bpy_struct)

base class — bpy_struct

class bpy.types.MeshLoop(bpy_struct)

Loop in a Mesh data-block

bitangent

Bitangent vector of this vertex for this polygon (must be computed beforehand using calc_tangents, use it only if really needed, slower access than bitangent_sign)

Type: mathutils.Vector of 3 items in [-1, 1], default (0.0, 0.0, 0.0), (readonly)

bitangent_sign

Sign of the bitangent vector of this vertex for this polygon (must be computed beforehand using calc_tangents, bitangent = bitangent_sign * cross(normal, tangent))

Type: float in [-1, 1], default 0.0, (readonly)

edge_index

Edge index

Type: int in [0, inf], default 0

index

Index of this loop

Type: int in [0, inf], default 0, (readonly)

normal

Local space unit length split normal vector of this vertex for this polygon (must be computed beforehand using calc_normals_split or calc_tangents)

Type: mathutils.Vector of 3 items in [-1, 1], default (0.0, 0.0, 0.0)

tangent

Local space unit length tangent vector of this vertex for this polygon (must be computed beforehand using calc_tangents)

Type: mathutils.Vector of 3 items in [-1, 1], default (0.0, 0.0, 0.0), (readonly)

vertex_index

Vertex index

Type: int in [0, inf], default 0

classmethod bl_rna_get_subclass(id, default=None)

Parameters: id (string) – The RNA type identifier.
Returns: The RNA type or default when not found.
Return type: bpy.types.Struct subclass

classmethod bl_rna_get_subclass_py(id, default=None)

Parameters: id (string) – The RNA type identifier.
Returns: The class or default when not found.
Return type: type
