basename

center

The midpoint between the head and the tail. (readonly)

children

A list of all the bones children. Warning: takes O(len(bones)) time. (readonly)

children_recursive

A list of all children from this bone. Warning: takes O(len(bones)**2) time. (readonly)

children_recursive_basename

vector

The direction this bone is pointing. Utility function for (tail - head) (readonly)

x_axis

Vector pointing down the x-axis of the bone. (readonly)

y_axis

Vector pointing down the y-axis of the bone. (readonly)

z_axis

Vector pointing down the z-axis of the bone. (readonly)

align_roll(vector)

Align the bone to a localspace roll so the Z axis points in the direction of the vector given

Parameters:vector (float array of 3 items in [-inf, inf]) – Vector
align_orientation(other)

Align this bone to another by moving its tail and settings its roll the length of the other bone is not used.

parent_index(parent_test)

The same as ‘bone in other_bone.parent_recursive’ but saved generating a list.

transform(matrix, scale=True, roll=True)

Transform the the bones head, tail, roll and envelope (when the matrix has a scale component).

Parameters:
