| Abstract | AbstractIn this paper, we propose a fragment-based evaluation method for non-uniform B-spline surfaces using recent programmable graphics hardware (GPU). A position on a non-uniform B-spline surface is evaluated by the linear combination of both control points and B-spline basis functions. Hence the computational costs can be reduced by pre-computing a knot interval of a parameter from a knot vector. We show that efficient computation of positions and normal vectors for B-spline surfaces can be done on GPUs by applying these ideas. Our algorithm computes an exact position, a derivative and a curvature per fragment. We demonstrate that this achieves high-quality surface rendering. We also discuss about the extension to NURBS and trimmed surfaces. |
