安装就可以在环境配置好的情况下使用pip安装:
pip install polyscope
如果提示找不到库文件,no moudle的话可以试着把安装下来的polyscope文件夹放在和想要运行的py文件的同一目录下。
而我们安装下来的polyscope文件夹在哪里呢?它们应该位于安装目录中的"Lib/site-packages"中,我的如下图所示:
但是装好之后我们运行一个网上的例程:
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()
还是有错误,找不到polyscope_bindings,我的解决办法是在这个目录下面还应该有一个这个文件:
把他的名字改成polyscope_bindings.pyd就可以解决,库就可以跑通了。但是原例程因为没有给数组所有还有逻辑错误,随便给几个就可以运行了:
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("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()
这就可以成功使用了
