Detailed Description

Structure describing scale, rotation and translation transformation in 2D space.

Rotation is stored as angle in radians.

Member Function Documentation

static SRTValue2D create ( Matrix3x3  matrix )

static

Attempts to create a SRT object from a given transformation 3x3 matrix.

Note: A matrix is decomposable into SRT if its column vectors are orthogonal to each other.

Parameters

matrix

The transformation 3x3 matrix.

Returns

A SRTValue3D object if the matrix is decomposable, null otherwise.
