Member Function Documentation

void ARBoundingBox::Calc2DTo2DProjection (   )

Calculates the 2D to 2D projection transformation. The calculate 3x3 matrix can be used to calculate x and y coordinates for a quadrialateral by specifying u and v coordinates. The is matrix is commonly used in texture mapping where a square image in transformed to a quadrilateral.

void ARBoundingBox::CalcCorners (  int *  edgesLeft, int *  edgesTop, int *  edgesRight, int *  edgesBottom )

Calculates the four corners from the supplied edges. The four corners are the potential markers corners within the bounding box region.

double* ARLib::Detection::ARBoundingBox::Get2DTo2DProjectionMatrix (   )  [inline]

Returns the 2D to 2D projection matrix. Valid value will only be returned if the Calc2DTo2DProjection function has already been called. Returns: A double pointer to the first element in the 3x3 array.
