Bug? Volume plotting results in a perspective(?) view.

mikerife commented 1 year ago

🤓 Before submitting the issue

[X] I have visited the Troubleshooting section.
[X] I have searched among the existing issues.
[X] I am using a Python virtual environment.
[X] I am using the latest version of PyMAPDL and its dependencies (fully updated virtual environment). You can update them using pip install --upgrade --upgrade-strategy eager ansys-mapdl-core in your activated virtual environment.

🔍 Description of the bug

A VPLOT of a cylindrical volume has the cylindrical faces in I think a perspective view. Instead of them looking straight. And something funky is going on with the circular edges.

Enabling parallel projection results in this:

🕵️ Steps To Reproduce

from ansys.mapdl.core import launch_mapdl
mapdl = launch_mapdl()
print(mapdl)
mapdl.clear()
mapdl.prep7()

inn_rad=50.0e-2
out_rad=55.0e-2
start_surface=0.0
end_surface=30.0e-2
theta1=0.0
theta2=360.0

secnum_cyl = mapdl.cyl4(0.0, 0.0, inn_rad, theta1, out_rad, theta2, (end_surface-start_surface))
mapdl.vplot()

pl = mapdl.vplot(return_plotter = True)
pl.enable_parallel_projection()
pl.show()

mapdl.exit()

I'm not sure with the updates recently to VTK and/or PyVista, and PyMAPDL if this is expected or not. MIke

Interesting.... in MacOS I get...

And then:

I shall check later on Windows.

@mikerife your pyvista version (0.38.5) seems quite old. Can you update??

You can update all dependencies running the code from the fourth item in this issue

Which is:

pip install --upgrade --upgrade-strategy eager ansys-mapdl-core

germa89 commented 1 year ago

Regarding the differences between the lines and the volume, this is probably due to how we retrieves the lines (from the IGES file, which can include arcs) vs how we retrieves the volumes (from a fake mesh).

I do not think we can fix anything on client side but I will think about it.

mikerife commented 1 year ago

@germa89 what do the plots look like when the cpos is set so that we are looking down the Z axis on macOS? Just curious.

germa89 commented 1 year ago

It looks.... artistic I would say...

mapdl.vplot(cpos=(0,0,1))

If I disable show_lines:

mapdl.vplot(cpos=(0,0,1), show_lines=False)

mikerife commented 1 year ago

@germa89 BTW sorry - had too many venvs and cmd windows open and used wrong one to start JL. Just did a fresh venv for this and installed PyMAPDL. Now everything is updated and same perspective view.

germa89 commented 11 months ago

Don't worry @mikerife !! It happens to all of us from time to time! :)

Closing issue because I opened #2478
