Detailed Description

The Class MatrixF4x4.

Internal the matrix is structured as

[ x0 , y0 , z0 , w0 ] [ x1 , y1 , z1 , w1 ] [ x2 , y2 , z2 , w2 ] [ x3 , y3 , z3 , w3 ]

it is recommend that when setting the matrix values individually that you use the set{x,#} methods, where 'x' is either x, y, z or w and # is either 0, 1, 2 or 3, setY1 for example. The reason you should use these functions is because it will map directly to that part of the matrix regardless of whether or not the internal matrix is column major or not. If the matrix is either or length 9 or 16 it will be able to determine if it can set the value or not. If the matrix is of size 9 but you set say w2, the value will not be set and the set method will return without any error.

Constructor & Destructor Documentation

◆ MatrixF4x4()

com.maxst.ar.MatrixF4x4.MatrixF4x4 ( )

Instantiates a new matrixf4x4. The Matrix is assumed to be Column major, however you can change this by using the setColumnMajor function to false and it will operate like a row major matrix.

Here is the call graph for this function:

Member Function Documentation

◆ getMatrix()

float [] com.maxst.ar.MatrixF4x4.getMatrix ( )

Gets the matrix.

Returns: the matrix, can be null if the matrix is invalid

Here is the caller graph for this function:

◆ isColumnMajor()

boolean com.maxst.ar.MatrixF4x4.isColumnMajor ( )

Find out if the stored matrix is column major

Returns

◆ multiplyMatrix()

void com.maxst.ar.MatrixF4x4.multiplyMatrix	(	float[]	input,
		int	inputOffset,
		float[]	output,
		int	outputOffset
	)

Here is the caller graph for this function:

◆ multiplyMatrix4x4ByMatrix()

void com.maxst.ar.MatrixF4x4.multiplyMatrix4x4ByMatrix ( MatrixF4x4 matrixf )

Multiply matrix4x4 by matrix.

Parameters

matrixf the matrixf

for(int i = 0; i < 4; i++){ for(int j = 0; j < 4; j++){

int k = i * 4; bufferMatrix[0 + j] += this.matrix[k + j] * matrix[0 * 4 + i]; bufferMatrix[1 * 4 + j] += this.matrix[k + j] * matrix[1 * 4 + i]; bufferMatrix[2 * 4 + j] += this.matrix[k + j] * matrix[2 * 4 + i]; bufferMatrix[3 * 4 + j] += this.matrix[k + j] * matrix[3 * 4 + i]; } }

Here is the call graph for this function:

◆ multiplyVector3fByMatrix()

void com.maxst.ar.MatrixF4x4.multiplyVector3fByMatrix ( Vector3f vector )

Multiply the given vector by this matrix. This should only be used if the matrix is of size 9 (use the matrix.size() method).

Parameters

vector A vector of length 3.

Here is the call graph for this function:

◆ multiplyVector4fByMatrix()

void com.maxst.ar.MatrixF4x4.multiplyVector4fByMatrix ( Vector4f vector )

Multiply the given vector by this matrix. This should only be used if the matrix is of size 16 (use the matrix.size() method).

Parameters

vector A vector of length 4.

Here is the call graph for this function:

◆ set()

void com.maxst.ar.MatrixF4x4.set ( MatrixF4x4 source )

◆ setColumnMajor()

void com.maxst.ar.MatrixF4x4.setColumnMajor ( boolean colMajor )

Set whether the internal data is col major by passing true, or false for a row major matrix. The matrix is column major by default.

Parameters

colMajor

◆ setMatrix()

void com.maxst.ar.MatrixF4x4.setMatrix ( float[] matrix )

Sets the matrix from a float[16] array. If the matrix you set isn't 16 long then the matrix will be set as invalid.

Parameters

matrix the new matrix

◆ setW0()

void com.maxst.ar.MatrixF4x4.setW0 ( float value )

◆ setW1()

void com.maxst.ar.MatrixF4x4.setW1 ( float value )

◆ setW2()

void com.maxst.ar.MatrixF4x4.setW2 ( float value )

◆ size()

int com.maxst.ar.MatrixF4x4.size ( )

◆ transpose()

void com.maxst.ar.MatrixF4x4.transpose ( )

This will rearrange the internal structure of the matrix. Be careful though as this is an expensive operation.
