python polyscope庫的安裝和例程
阿新 • • 發佈:2020-11-13
安裝就可以在環境配置好的情況下使用pip安裝:
pip install polyscope
- 1
如果提示找不到庫檔案,no moudle的話可以試著把安裝下來的polyscope資料夾放在和想要執行的py檔案的同一目錄下。
而我們安裝下來的polyscope資料夾在哪裡呢?它們應該位於安裝目錄中的"Lib/site-packages"中,我的如下圖所示:
但是裝好之後我們執行一個網上的例程:
import polyscope as ps
# Initialize polyscope
ps.init()
### Register a point cloud
# `my_points` is a Nx3 numpy array
ps.register_point_cloud("my points", my_points)
### Register a mesh
# `verts` is a Nx3 numpy array of vertex positions
# `faces` is a Fx3 array of indices, or a nested list
ps.register_surface_mesh("my mesh", verts, faces, smooth_shade=True)
# Add a scalar function and a vector function defined on the mesh
# vertex_scalar is a length V numpy array of values
# face_vectors is an Fx3 array of vectors per face
ps.get_surface_mesh("my mesh").add_scalar_quantity("my_scalar",
vertex_scalar, defined_on='vertices', cmap='blues')
ps.get_surface_mesh("my mesh").add_vector_quantity("my_vector",
face_vectors, defined_on='faces', color=(0.2, 0.5, 0.5))
# View the point cloud and mesh we just registered in the 3D UI
ps.show()

還是有錯誤,找不到polyscope_bindings,我的解決辦法是在這個目錄下面還應該有一個這個檔案:
把他的名字改成polyscope_bindings.pyd就可以解決,庫就可以跑通了。但是原例程因為沒有給陣列所有還有邏輯錯誤,隨便給幾個就可以運行了:
import polyscope as ps
import numpy as np
# Initialize polyscope
ps.init()
### Register a point cloud
# `my_points` is a Nx3 numpy array
my_points=np.array([[1,1,1],[1,2,3],[1,2,4],[2,5,3],[2,2,2]])
ps.register_point_cloud("my points", my_points)
### Register a mesh
# `verts` is a Nx3 numpy array of vertex positions
# `faces` is a Fx3 array of indices, or a nested list
verts=np.array([[1,1,1],[1,2,3],[1,2,4],[2,5,3],[2,2,2]])
faces=np.array([[1,1,1],[1,2,3],[1,2,4],[2,4,3],[2,2,2]])
ps.register_surface_mesh("my mesh", verts, faces, smooth_shade=True)
# Add a scalar function and a vector function defined on the mesh
# vertex_scalar is a length V numpy array of values
# face_vectors is an Fx3 array of vectors per face
vertex_scalar = np.array([1,2,3,4,5])
face_vectors=np.array([[1,1,1],[1,2,3],[1,2,4],[2,5,3],[2,2,2]])
ps.get_surface_mesh("my mesh").add_scalar_quantity("my_scalar",
vertex_scalar, defined_on='vertices', cmap='blues')
ps.get_surface_mesh("my mesh").add_vector_quantity
