Static Methods

angle(Sp3dV3D a, Sp3dV3D b) double
(en)Return the radian between vector A and vector B. When converting to degrees, degrees = radian*180/pi. [...]
ave(List<Sp3dV3D> v) Sp3dV3D
(en)Return the averaged vector. [...]
cross(Sp3dV3D a, Sp3dV3D b) Sp3dV3D
(en)Return cross product. [...]
dist(Sp3dV3D a, Sp3dV3D b) double
(en)Return euclidean distance. [...]
dot(Sp3dV3D a, Sp3dV3D b) double
(en)Return dot product. [...]
from_dict(Map<String, dynamic> src) Sp3dV3D
Restore this object from the dictionary. [...]
proj(Sp3dV3D v, Sp3dV3D nor_v) Sp3dV3D
(en)Return projection vector. [...]
surface_normal(List<Sp3dV3D> face) Sp3dV3D
(en)Calculates and returns the surface normal. The order of the vertices must be counterclockwise. Note that this cannot be used for degenerate polygons. [...]
