🐞 Description of the bug

Couldn't able to visualize the geometry, standalone trame, PyVista trame or provided TrameVisualizer Class,

from ansys.geometry.core.plotting.trame_gui import TrameVisualizer
view = TrameVisualizer()
view.set_scene(plotter=plotter)
view.show()
CRITICAL -  -  logger - handle_exception - Uncaught exception
Traceback (most recent call last):
  File "d:\Research\pygeom_plotter_test\geom_plotter.py", line 86, in <module>
    view.set_scene(plotter=plotter)
  File "C:\Users\username\.ansys_python_venvs\.venv_pyansys\lib\site-packages\ansys\geometry\core\plotting\trame_gui.py", line 64, in set_scene
    view = plotter_ui(plotter.scene)
AttributeError: 'PlotterHelper' object has no attribute 'scene'

📝 Steps to reproduce

Pass the plotter object to respective implementation, e.g.,

TrameVisualizer.set_scene(plotter)

💻 Which operating system are you using?

Windows

📀 Which ANSYS version are you using?

Ansys 24R1

🐍 Which Python version are you using?

3.12

📦 Installed packages

Installed all the pyansys meta-pacakages using Ansys Python Manager.

Additionally install following packages.
trame trame-vuetify trame-vtk

Hi @abhishekchitwar - the way to use the trame visualizer is not this one.

Please do as follows

import ansys.geometry.core as pygeo

pygeo.USE_TRAME = True

# Do your stuff...
#
#

design.plot()

Our PyAnsys Geometry main objects (design, component, body) all have a "plot()" method you can use easily this way with your intended backend

Hi @RobPasMue

I attempted the following code snippet, but the design plot still appears in a desktop window. I'm looking for a way to display this design on a server or local URL instead.

from ansys.geometry.core import launch_modeler
from ansys.geometry.core.misc import UNITS, Distance, DEFAULT_UNITS
from ansys.geometry.core.math import Point2D
from ansys.geometry.core.sketch import Sketch
from ansys.geometry.core.plotting import PlotterHelper
import pyvista as pv
#from trame_app import TrameApp
DEFAULT_UNITS.LENGTH = UNITS.mm
modeler = launch_modeler(mode='spaceclaim')

launch_modeler.USE_TRAME=True

base_sketch = Sketch()
base_sketch.segment(Point2D([0,0]), Point2D([0,10]))
base_sketch.segment(Point2D([0,10]), Point2D([10,10]))
base_sketch.segment(Point2D([10,10]), Point2D([10,0]))
base_sketch.segment(Point2D([10,0]), Point2D([0,0]))


# Start by creating the Design
design = modeler.create_design("ModelingDemo")

# Create a body directly on the design by extruding the sketch
body = design.extrude_sketch(
    name="Design_Body", sketch=base_sketch, distance=Distance(10, unit=UNITS.mm)
)

# design plot
design.plot()

# plotter, this is for test
# plot_list = [body]
# plotter = PlotterHelper(use_trame=True)
# plotter.plot(plot_list)

Hi @RobPasMue,

I just updated the argument with design.plot(use_trame= True), getting following issue.

    raise TypeError(
TypeError: Server using client_type='vue3' while we expect 'vue2'

It seems, it requires update from TrameVisualizer.

Hi @RobPasMue,

I just updated the self.server = get_server(client_type='vue2') with TrameVisualizer, it worked as updated. Thanks!

Thanks!

RobPasMue commented

Oh interesting! So you needed to pass the client type to the TrameVisualizer.. We might have to expose this somehow. Could you share your final script? I guess you had to modify your local version of PyAnsys Geometry, right?

Hi @RobPasMue,

yeah, I modified the local pygeometry installation.

It would be great if TrameVisualizer exposes several methods in context of remote visualization, e.g.

    def get_url(self):
        return f"http://{self.address}:{self.port}"

Ease for developer to configure address and port as per requirement.

Here is the final code! Example test case developed by @agvarghe

from ansys.geometry.core import launch_modeler
from ansys.geometry.core.misc import UNITS, Distance, DEFAULT_UNITS
from ansys.geometry.core.math import Point2D
from ansys.geometry.core.sketch import Sketch
from ansys.geometry.core.plotting import PlotterHelper
import pyvista as pv

DEFAULT_UNITS.LENGTH = UNITS.mm
modeler = launch_modeler(mode='spaceclaim')

# launch_modeler.USE_TRAME=True

base_sketch = Sketch()
base_sketch.segment(Point2D([0,0]), Point2D([0,10]))
base_sketch.segment(Point2D([0,10]), Point2D([10,10]))
base_sketch.segment(Point2D([10,10]), Point2D([10,0]))
base_sketch.segment(Point2D([10,0]), Point2D([0,0]))


# Start by creating the Design
design = modeler.create_design("ModelingDemo")

# Create a body directly on the design by extruding the sketch
body = design.extrude_sketch(
    name="Design_Body", sketch=base_sketch, distance=Distance(10, unit=UNITS.mm)
)

# design plot
design.plot(use_trame=True)

Thanks!

Awesome, we will bring these features in for sure!

We will delegate the actual remote visualization to a different project we are working on. On this one we will just fix the inputs needed to use vue3 or vue2 =)

This issue will be closed by #1148 - thanks @AlejandroFernandezLuces
