获取曲面上最近的点- Maya - Python

import maya.cmds as cmds
import math

def get_closest_point_on_surface(surface, target_point):
    closest_point = None
    min_distance = float('inf')

    # 获取曲面上的所有控制点
    control_points = cmds.ls(surface + '.cv[*]', flatten=True)

    for control_point in control_points:
        # 获取控制点的位置
        position = cmds.xform(control_point, query=True, translation=True, worldSpace=True)

        # 计算控制点与目标点之间的距离
        distance = math.sqrt((position[0] - target_point[0]) ** 2 + (position[1] - target_point[1]) ** 2 + (position[2] - target_point[2]) ** 2)

        # 更新最小距离和对应的控制点
        if distance < min_distance:
            min_distance = distance
            closest_point = control_point

    return closest_point

# 示例用法
surface = 'pPlane1'  # 曲面名称
target_point = [1.0, 2.0, 3.0]  # 目标点坐标

closest_point = get_closest_point_on_surface(surface, target_point)
print('最近的点是：', closest_point)
