Hi!
I am encountering difficulty importing external wavefront files to Pychrono
(win-64_pychrono-8.00-py39_3631), as in wavefront files as exported from
Blender. I recreated the problem with some of the wavefront files included
in the Pychrono code distribution, after I imported these wavefront files
into Blender and then re-exported them. I was also able to create the same
problem by importing the wavefront files into Meshlab (2020.07, portable
Windows version) and re-exporting them several different ways.
Could you comment on the EXACT export options that might be used to save a
wavefront file that's able to be successfully imported to Pychrono?
#----------------------------------------------------
import pychrono as chrono
try:
mesh = chrono.ChTriangleMeshConnected()
success =
mesh.LoadWavefrontMesh(chrono.etChronoDataFile('models/bulldozer/shoe_view.obj'))
#OK!
if not success:
print("Try 1 (native Wavefront)=>Error loading mesh!")
except Exception as e:
print("An error occurred: ", e)
try:
mesh = chrono.ChTriangleMeshConnected()
success =
mesh.LoadWavefrontMesh(chrono.etChronoDataFile('models/RE-EXPORT/shoe_view_out.obj'))
#FAIL!
if not success:
print("Try 2 (Wavefront imported into MeshLab and
re-exported)=>Error loading mesh!")
except Exception as e:
print("An error occurred: ", e)
#----------------------------------------------------
Code output looks like this:
Error loading OBJ file ...path2file...
tiny_obj warning message:
tiny_obj error message: Cannot open file ...path2file...
Try 2 (Wavefront imported into MeshLab and re-exported)=>Error loading mesh!
