Hi,
I wonder how to export voxel data using Python API. Is there anyone who can help me? Thank you!
How to export voxel data using python API?
I normally just get it from the h5 input file if you know where it is (in Acoustics it's under Meshes, then eventually in a dataset called voxels - you can use HDF5View to examine your input file).
Some (untested) code to get you started:
import h5py
import s4l_v1 as s4l
def geth5Dataset(h5f, group_name, dataset_name):
def find_dataset(name):
if dataset_name in name:
return name
with h5py.File(h5f, 'r') as f:
k = f[group_name].visit(find_dataset)
return f[group_name + '/' + k][()]
def getVoxels(h5f):
return geth5Dataset(h5f, 'Meshes', 'voxels')
sim_idx = 0 # Simulation number
sim = s4l.document.AllSimulations[sim_idx]
file_name = sim.GetInputFileName()
file_path = "c:/file_path/"
vox = getVoxels(file_path + file_name)
