      • setIdentity

        public abstract Matrix setIdentity()
        Set this matrix to be the identity matrix.
        Returns:
        this

      • invert

        public abstract Matrix invert()
        Invert this matrix

        this

      • load

        public abstract Matrix load​(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​(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​(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​(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
