Abstract:
1. A method of identifying a selected image object displayed within a three-dimensional graphical area bounded by partitioning boundaries, the image object being selected with an input device having an associated viewing perspective defined by a viewing position and a viewing orientation vector pointing from the viewing position, said method comprising: assigning coordinate points to boundaries wherein each boundary point forms a boundary axis with the viewing position and the viewing orientation vector forms an angle with each boundary axis ( using angles formed between each boundary axis and the viewing orientation vector to determine first and second consecutive boundary axes that the viewing orientation vector lies between wherein each of the first and second boundary axes have associated first and second boundary points defining a selected boundary where a selected image object is located ( determining the coordinate of a selected point on the selected boundary dependent on angles formed by the selected boundary, the first and second boundary axes, and the viewing orientation vector ( matching the selected point coordinate with the coordinate of one of a plurality of image object coordinates to identify the selected image object (
