For integration into scientific tools such as Jupyter, there needs to be a clearly stated license. The MIT license would be great for this.

HexaLab gets stuck at Loading... when I try to load some of the larger datasets (>10 MB), for instance kiss_hex.mesh (17.5 MB). Tested in Chrome and Firefox on two different machines, same thing happens every time.

Error:
Cannot enlarge memory arrays. Either (1) compile with -s TOTAL_MEMORY=X with X higher than the current value 1073741824, (2) compile with -s ALLOW_MEMORY_GROWTH=1 which allows increasing the size at runtime but prevents some optimizations, (3) set Module.TOTAL_MEMORY to a higher value before the program runs, or (4) if you want malloc to return NULL (0) instead of this abort, compile with -s ABORTING_MALLOC=0

The following python3.5 script wil print the number of vertices in each mesh (.mesh and .vtk). Run it from the top level or datasets dir in the repo. It prints the list of meshes in ascending order by vertex count.

import glob

def findstring(filename,key,idx):
  with open(filename) as f:
    datafile = f.readlines()
    for i in range(len(datafile)):
      line = datafile[i]
      if key in line.lower():
        tokens = line.split()
        # get the vertex count from the next line
        if tokens[idx].lower() == key:
          return int(datafile[i+1].strip())
        return int(tokens[idx])
    return False

numMeshFiles = 0 
meshes = dict()
for filename in glob.iglob('./' + '**/*.mesh', recursive=True):
  verts = findstring(filename, "vertices",-1)
  meshes[filename] = verts
  numMeshFiles = numMeshFiles + 1 
    
numVtkFiles = 0 
for filename in glob.iglob('./' + '**/*.vtk', recursive=True):
  verts = findstring(filename, "points",-2)
  meshes[filename] = verts
  numVtkFiles = numVtkFiles + 1 


sortedMeshes = sorted(meshes, key=meshes.__getitem__)
for m in sortedMeshes:
  print(m,meshes[m])
