| titleOfInvention | Method for virtually simulating incision based on Bezier curve |
| abstract | The invention provides a method for virtually simulating an incision based on Bezier curve. The method comprises the following steps: (1) drawing an enclosed region of the Bezier curve in a tissue structure and marking the enclosed area as a region P; calculating all grid points covered by the region P, marking the region of all the covered grid points as a region E, and then deleting the region E; (3) restructuring grids: A. calculating peripheral points of the region P, marking the region of the calculated peripheral points as a region S and storing the region S; B. operating the regions P and S, and finding out corresponding nearest neighboring point pair groups T, wherein each group comprises four points; and C. drawing T according to a polygon drawing method of computer graphics, wherein each group comprises four points; and (4) displaying cyclically, storing the starting point and the terminal point of an incision all the time, storing two intermediate points dynamically, and drawing a smooth incision according to a subdivision degree. Under the same computer configuration condition, by the Bezier-curve-based incision virtual method in incision operation simulation, the grid intensity can be reduced, and fps (frames per second) is improved, the system can operate more smoothly and a better smooth effect can be achieved. |
