Class Detail

BiTran2(m)

Creates 3x3 homogenous transformation that also maintains its own inversion. This is usually more effient than calling m.invert().

Field Detail

{Matrix3} inverse

Matrix3 that stores the inverse transformation.

{Matrix3} matrix

Matrix3 that stores the transformation.

Method Detail

copy()

Create and return a copy of this matrix.

mult(mb)

Apply transformation (in-place) and return this instance.

{BiTran2} reset()

Reset the current matrix to identity.

rotate(a, pt)

Apply rotation (in-place) and return this instance.

scale(fx, fy)

Apply scaling (in-place) and return this instance.

{Matrix3} set(m)

Set the current matrix.

Parameters:
{Matrix3|float[9]} m: (optional) defaults to identity matrix [1, 0, 0, 0, 1, 0, 0, 0, 1]

{string} toString()

Return string representation '[[0, 1, 2], [3, 4, 5], [6, 7, 8]]'.

translate(dx, dy)

Apply translation (in-place) and return this instance.
