MarSTDv2004: CMatrix3 Class Reference

CMatrix3 Class Reference


Public Member Functions
void	makeIdentity ()
	Creates the identity matrix. Multiplying a vector by the identity matrix results in the same vector.
void	transpose ()
	Transpose matrix. Swaps rows / columns.
void	makeXRotation (float r)
	Create a rotation around the X axis. r is given in radians.
void	makeYRotation (float r)
	Create a rotation around the Y axis. r is given in radians.
void	makeZRotation (float r)
	Create a rotation around the Z axis. r is given in radians.
void	makeRotation (float x, float y, float z)
	Create a rotation around the X, Y and Z axis. All rotations are given in radians. The will rotate about the X axis first, then Y axis and finally the Z axis.
void	makeScaling (float x, float y, float z)
	Creates a scaling matrix.
void	mul (float x, float y, float z, float xout, float yout, float *zout)
	Multiplies a 3D point with this matrix and stores the result in xout, yout and zout.
CVector	mul (CVector &vector, CVector &out)
	Multiplies a vector by this matrix, storing the result in out.
void	mul (CMatrix3 &matrix)
	Multiplies this matrix bu matrix. This had the effect of concatenating transformations.
float	determinant ()
	Calculate the determinant.
void	invert ()
	Calculate the inverse matrix and replace the current matrix with it.
float &	operator() (int x, int y)
	Return a value at location (x, y).
CVector	operator * (CVector &vector)
	Multiply by vector.
CMatrix3 &	operator *= (CMatrix3 &matrix)
	Multiply by matrix. Eg. Matrix3 final = matrix1 * matrix2 * matrix3;.
Public Attributes
float	v [9]
	3x3 matrix data.
