Method Detail

transform

public static Point2D_F32 transform(Homography2D_F32 H,
                                    Point2D_F32 orig,
                                    Point2D_F32 result)

Applies a 2D homography transform to the point and stores the results in another variable. b = H*a, where 'a' is the input/orig point, 'b' is the output/result point, and 'H' is a homography from a to b.

Parameters:

H - Homography transform

orig - Original point being transformed. Not modified.

result - Where the results are stored. Can be the same as orig. If null a new instance is created. Modified.

Returns:

Transformed point.

transform

public static Point2D_F32 transform(Homography2D_F32 H,
                                    float x,
                                    float y,
                                    Point2D_F32 result)

Applies a 2D homography transform to the point and stores the results in another variable. b = H*a, where 'a' is the input/orig point, 'b' is the output/result point, and 'H' is a homography from a to b.

Parameters:

H - Homography transform

x - Original x-coordinate

y - Original y-coordinate

result - Where the results are stored. Can be the same as orig. If null a new instance is created. Modified.

Returns:

Transformed point.
