Although a number of different algorithms have been described in the literature for merging
two or more B-spline/Bézier curves and stitching B-spline surfaces, these techniques are not
suitable for virtual reality applications that require the user to effortlessly combine multiple
dissimilar patches in real-time to create the final object shape. This paper presents a novel
approach for merging arbitrary B-spline surfaces within a very low tolerance limit. The
technique exploits blending matrices that are independent of the control point positions and …
