Matrix

protected Matrix()

Constructor for Matrix.

Method Detail

setIdentity

public abstract Matrix setIdentity()

Set this matrix to be the identity matrix.

Returns:

this

invert

public abstract Matrix invert()

Invert this matrix

Returns:

this

load

public abstract Matrix load(java.nio.FloatBuffer buf)

Load from a float buffer. The buffer stores the matrix in column major (OpenGL) order.

Parameters:

buf - A float buffer to read from

Returns:

this

loadTranspose

public abstract Matrix loadTranspose(java.nio.FloatBuffer buf)

Load from a float buffer. The buffer stores the matrix in row major (mathematical) order.

Parameters:

buf - A float buffer to read from

Returns:

this

negate

public abstract Matrix negate()

Negate this matrix

Returns:

this

store

public abstract Matrix store(java.nio.FloatBuffer buf)

Store this matrix in a float buffer. The matrix is stored in column major (openGL) order.

Parameters:

buf - The buffer to store this matrix in

Returns:

this

storeTranspose

public abstract Matrix storeTranspose(java.nio.FloatBuffer buf)

Store this matrix in a float buffer. The matrix is stored in row major (maths) order.

Parameters:

buf - The buffer to store this matrix in

Returns:

this

transpose

public abstract Matrix transpose()

Transpose this matrix

Returns:

this

setZero

public abstract Matrix setZero()

Set this matrix to 0.

Returns:

this

determinant

public abstract float determinant()

Returns:

the determinant of the matrix
