Embodiment Construction
[0093]Step 1: After receiving the original discrete point data, the host computer detects whether the number of discrete point sets is greater than the segmentation threshold. If it is not greater than the threshold, the host directly uses the point-by-point interpolation method to construct a triangular network; if it is greater than the segmentation threshold, the point set is accurately divided into two sub-region point sets VL and VR according to the subscript. The host keeps the VL part and sends the VR part to the next node.
[0094] Step 2: At this time, if the number of VL and VR point sets is still greater than the threshold, continue to divide the VL and VR parts, so as to obtain VLL, VLR, VRL, VRR. Similarly, the node meter for point set segmentation needs to keep the L part after point set segmentation, and just pass the R part to the next available free node.
[0095] Step 3: Carry out point set segmentation according to the above steps until the number of point ...
