Get Mesh ValuesΒΆ
This example shows how to extract informations like vertex coordinates or vertex index incident to a face from a Mesh contained in a MeshSet, through numpy arrays.
This script can be executed by running the following command:
pytest --pyargs pymeshlab -k 'get_mesh_values'
tests/example_get_mesh_values.py
import pymeshlab
def example_get_mesh_values():
# lines needed to run this specific example
print('\n')
from . import samples_common
base_path = samples_common.samples_absolute_path()
output_path = samples_common.test_output_path()
# create a new MeshSet
ms = pymeshlab.MeshSet()
ms.load_new_mesh(base_path + 'chameleon.pts')
# applying some filters...
ms.apply_filter('point_cloud_simplification')
ms.apply_filter('surface_reconstruction_ball_pivoting')
ms.apply_filter('parametrization_trivial_per_triangle', textdim=1024)
ms.save_current_mesh(output_path + 'chameleon_simplified.obj')
ms.apply_filter('transfer_vertex_color_to_texture', textname='chameleon_simplified.png')
# get a reference to the current mesh
m = ms.current_mesh()
# get numpy arrays of vertices and faces of the current mesh
vertex_array_matrix = m.vertex_matrix()
face_array_matrix = m.face_matrix()
