The following classes are provided by the Mudbox SDK for aid in performing geometric and numerical computations:

• Vector - Represents a 3D vector or point with 23 bit floating point elements.
• Vector4 - A four dimensionsional vector (X, Y, Z, and W).
• Line - Represents a line segment in 3d space.
• Matrix - This class represents a 4x4 transformation matrix.
• Normal - Normal vector with 16 bit components.
• half_ - Half precision (16 bit) float class. Supports fast conversion between float and half precision.
