Pyvista---(4)pyvista中常用的函数和应用1

1. 多个图，类似于matplotlib

p = pv.Plotter(shape=(3, 3))
p.subplot(0, 0)

2. 指定颜色和平滑阴影

supertoroid.plot(color="tan", smooth_shading=True)

3. 创建点云

import pyvista as pv
import numpy as np
## 生成一组点云的坐标，然后构建点云的mesh
points = np.random.rand(30000, 3)
point_cloud = pv.PolyData(points)
print np.allclose(points, point_cloud.points)#检测是否一致
# 画点云
point_cloud.plot(eye_dome_lighting=True)

3.1 给点云赋值

## 给点云赋值，这里就把z轴坐标的值赋值给点云
data = points[:,-1]
point_cloud["value"] = data
point_cloud
