Hello,
I am a beginner in paraview,
I am trying to convert a .vtk Data file (DATASET POLYDATA) to a 3D voxel-based image having a .raw or .tif format. So I need to voxelise the domain(sample of particles) and to saved the data into a binary file (.raw or .tif) consisting of voxels with a value of either 0 or 255 which represent if the voxel is inside a particle or in a void space.
The .vtk file corresponds to slices of ellipsoid particles taken from a DEM software.
I was searching and I found that it could be possible to do using DataSet Resampling Filters but this function was disabled in my case.
I am using paraview 5.0.1
Thank you for helping me.
Here is an example for the data of a .vtk file of 1 particle with only three slices (to reduce the data):
