Matrix3x3f class

From Solid Graphics Wiki

Matrix3x3f class Namespace: SKL3D Base type: (None) Include: Skl3D.h Lib (Release): SKL.lib Lib (Debug): SKL_D.lib

The Matrix3x3f class is representation of 3x3 matrix of float values. The class is used mainly for rotational transformation of points and types derived or using the Point class, such as PointList class or Shape class.

Constructors

Default Matrix3x3f class constructor does not initialize the matrix fields to any value. This is on purpose for performance reasons. Use Initialize method to set the matrix values into the "identity matrix" state.

Default copy constructor can be used to copy one Matrix3x3f object to another.

Methods

Method name

Description

Initialize	Initializes the matrix to the "identity matrix" values. Identity matrix is an matrix which when it is used to transform a point coordinates the transformation will not modify the point coordinates.
RotateXYZ	Modifies matrix by adding rotation first around X, then Y, and then Z axis.
RotateZYX	Modifies matrix by adding rotation first around Z, then Y, and then X axis.
RotateYXZ	Modifies matrix by adding rotation first around Y, then X, and then Z axis.
RotateZXY	Modifies matrix by adding rotation first around Z, then X, and then Y axis.
InverseRotateXYZ	Modifies the matrix values by adding rotation inverse to the RotateXYZ method.
InverseRotateZYX	Modifies the matrix values by adding rotation inverse to the RotateZYX method.
InverseRotateYXZ	Modifies the matrix values by adding rotation inverse to the RotateYXZ method.
InverseRotateZXY	Modifies the matrix values by adding rotation inverse to the RotateZXY method.
GetRotationAnglesXYZ	Retrieves X, Y, Z angle values (in degrees) of XYZ rotation which the current matrix's value field values represent.
GetRotationAnglesZYX	Retrieves Z, Y, X angle values (in degrees) of XYZ rotation which the current matrix's value field values represent.
GetRotationAnglesYXZ	Retrieves Y, X, Z angle values (in degrees) of XYZ rotation which the current matrix's value field values represent.
GetRotationAnglesZXY	Retrieves Z, X, Y angle values (in degrees) of XYZ rotation which the current matrix's value field values represent.
Scale	Scales matrix values by given factor.
Transpose	Transposes the matrix values.

Operators

=	Assigns another Matrix3x3f, Matrix3x3d, or Matrix4x4f or Matrix4x4d to the matrix instance
const float*	Returns const pointer to the nine matrix's float values.
float*	Returns pointer to the nine matrix's float values.
*=	Multiplies the matrix with other Matrix3x3f instance.
