open3d.geometry.TetraMesh.create_from_point_cloud
函数将点云转化为四面体网格。
open3d.geometry.TetraMesh.create_from_point_cloud(point_cloud, alpha=0.0)
参数:
point_cloud
: open3d.geometry.PointCloud
,输入点云。alpha
: float
, 可选参数,表示网格大小的平均最短边长的倍数,alpha越小,生成的四面体越多,网格越细致,但同时造成运算效率降低。返回值:
open3d.geometry.TetraMesh
,返回通过点云生成的四面体网格。注意事项:
示例:
import open3d as o3d
import numpy as np
# Load point cloud
pcd = o3d.io.read_point_cloud("point_cloud.pcd")
# Create tetrahedral mesh using Alpha Shape algorithm
tet_mesh = o3d.geometry.TetraMesh.create_from_point_cloud(pcd)
# Visualize the tetrahedral mesh
o3d.visualization.draw_geometries([tet_mesh])
