Mesh Export Size Difference (Local/Remote) #2242

Closed mofibo closed 4 months ago

mofibo commented 5 months ago

Hello,

I noticed that when I export a mesh using:

mesh_var.export("path")

the file size is smaller than when I use:

file_obj = trimesh.exchange.stl.export_stl(mesh_var)
requests.put(url, data=file_obj, headers={"Content-Type": "application/octet-stream"})

For this example, in local, it is 15MB and remote 42MB

Can anyone explain why the sizes are different?

Thanks!

Hey, is it possible it's the difference between binary and ASCII STL exports? 

In [9]: m = trimesh.creation.icosphere()

In [10]: len(m.export(file_type='stl_ascii'))
Out[10]: 371039

In [11]: len(m.export(file_type='stl'))
Out[11]: 64084
