Method Detail

aquireInstance

public static Matrix3 aquireInstance()

gets a pooled instance. Return the object with releaseInstance. Matrix is initialized to identity

Returns:

releaseInstance

public static void releaseInstance(Matrix3 instance)

returns a matrix into the object pool for a caller of aquireInstance.

setIdentity

public void setIdentity()

Overrides:

setIdentity in class Matrix

epsilonEquals

public static boolean epsilonEquals(Matrix3 a,
                                    Matrix3 b,
                                    float e)

setRotationZ

public static void setRotationZ(Matrix3 qrel,
                                float theta)

set the matrix to be a rotation about the z axis by an amount theta

Parameters:

qrel -

setRotationX

public static void setRotationX(Matrix3 qrel,
                                float theta)

set the matrix to be a rotation about the z axis by an amount theta

Parameters:

qrel -

setRotationY

public static void setRotationY(Matrix3 qrel,
                                float theta)

set the passed in matrix to be a rotation about the y axis by theta radians

Parameters:

qrel -

setRandomRotationMatrix

public static Matrix3 setRandomRotationMatrix(Matrix3 result)

Creates a random rotation matrix

Parameters:

result -

Returns:
