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 face (must be computed beforehand using calc_tangents, use it only if really needed, slower access than bitangent_sign) (array of 3 items, in [-1, 1], default (0.0, 0.0, 0.0), readonly)

Type:

mathutils.Vector

bitangent_sign

Sign of the bitangent vector of this vertex for this face (must be computed beforehand using calc_tangents, bitangent = bitangent_sign * cross(normal, tangent)) (in [-1, 1], default 0.0, readonly)

Type:

float

edge_index

Edge index (in [0, inf], default 0)

Type:

int

index

Index of this loop (in [0, inf], default 0, readonly)

Type:

int

normal

The normal direction of the face corner, taking into account sharp faces, sharp edges, and custom normal data (array of 3 items, in [-1, 1], default (0.0, 0.0, 0.0), readonly)

Type:

mathutils.Vector

tangent

Local space unit length tangent vector of this vertex for this face (must be computed beforehand using calc_tangents) (array of 3 items, in [-1, 1], default (0.0, 0.0, 0.0), readonly)

Type:

mathutils.Vector

vertex_index

Vertex index (in [0, inf], default 0)

Type:

int
