Voxelize a .stl

Walkthrough

Create a TargetGeometry from a .stl file by specifying the stlfilename and resolution i.e. the number of slices in the z-axis.

import vamtoolbox as vam
target_geo = vam.geometry.TargetGeometry(stlfilename=vam.resources.load("trifurcatedvasculature.stl"),resolution=250)

Show the voxel array of the TargetGeometry instance (array) with show().

target_geo.show()

Tip

Hover the mouse pointer over either slice and scroll to slice through the 3D voxel array at different z and x indices.

Alternatively, the vedo plotting package may be used to display the voxel array.

import vedo
vol = vedo.Volume(target_geo.array).legosurface(vmin=0.5,vmax=1.5)
vol.show(viewup="x")

Example file

examples/voxelizestl.py

import vamtoolbox as vam
target_geo = vam.geometry.TargetGeometry(stlfilename=vam.resources.load("trifurcatedvasculature.stl"),resolution=250)

target_geo.show()

import vedo
vol = vedo.Volume(target_geo.array).legosurface(vmin=0.5,vmax=1.5)
vol.show(viewup="x")


voxelizer = vam.voxelize.Voxelizer()
voxelizer.addMeshes(
    {vam.resources.load("trifurcatedvasculature.stl"):"print_body"}
)
array = voxelizer.voxelize("print_body",layer_thickness=0.1,voxel_value=1.0,voxel_dtype='uint8')
