NOTE: there is no visualization tool in slam, but we provide at the

end of this script exemplare code to do the visualization with an external solution

Importation of slam modules

import slam.io as sio
import slam.vertex_voronoi as svv
import numpy as np

mesh = sio.load_mesh("../examples/data/example_mesh.gii")
mesh.apply_transform(mesh.principal_inertia_transform)

<trimesh.Trimesh(vertices.shape=(2328, 3), faces.shape=(4652, 3))>

vert_vor = svv.vertex_voronoi(mesh)
print(mesh.vertices.shape)
print(vert_vor.shape)
print(np.sum(vert_vor) - mesh.area)

    -percent polygon with obtuse angle  29.4067067927773

(2328,)

VISUALIZATION USING EXTERNAL TOOLS

# Visualization visb_sc = splt.visbrain_plot(

mesh=mesh, tex=vert_vor, caption=”vertex voronoi”, cblabel=”vertex voronoi”

) visb_sc.preview()
