Plain usage of the plotly backend

This example shows the plain usage of the Plotly backend in the Visualization Interface Tool to plot different objects, including PyVista meshes, custom objects, and Plotly-specific objects.

from ansys.tools.visualization_interface.backends.plotly.plotly_interface import PlotlyBackend
from ansys.tools.visualization_interface.types.mesh_object_plot import MeshObjectPlot
from ansys.tools.visualization_interface import Plotter
import pyvista as pv
from plotly.graph_objects import Mesh3d


# Create a plotter with the Plotly backend
pl = Plotter(backend=PlotlyBackend())

# Create a PyVista mesh
mesh = pv.Sphere()

# Plot the mesh
pl.plot(mesh)


# Create a PyVista MultiBlock
multi_block = pv.MultiBlock()
multi_block.append(pv.Sphere(center=(-1, -1, 0)))
multi_block.append(pv.Cube(center=(-1, 1, 0)))

# Plot the MultiBlock
pl.plot(multi_block)

# Display the plotter

pl.show()

Now create a custom object

class CustomObject:
    def __init__(self):
        self.name = "CustomObject"
        self.mesh = pv.Cube(center=(1, 1, 0))

    def get_mesh(self):
        return self.mesh

    def name(self):
        return self.name


# Create a custom object
custom_cube = CustomObject()
custom_cube.name = "CustomCube"

# Create a MeshObjectPlot instance
mesh_object_cube = MeshObjectPlot(custom_cube, custom_cube.get_mesh())

# Plot the custom mesh object
pl.plot(mesh_object_cube)

Display the plotter again

Since Plotly is a web-based visualization, we can show the plot again to include the new object.

pl.show()

Add a Plotly Mesh3d object directly

custom_mesh3d = Mesh3d(
    x=[0, 1, 2],
    y=[0, 1, 0],
    z=[0, 0, 1],
    i=[0],
    j=[1],
    k=[2],
    color='lightblue',
    opacity=0.50
)
pl.plot(custom_mesh3d, name="CustomMesh3d")

# Show other plotly objects like Scatter3d
from plotly.graph_objects import Scatter3d

scatter = Scatter3d(
    x=[0, 1, 2],
    y=[0, 1, 0],
    z=[0, 0, 1],
    mode='markers',
    marker=dict(size=5, color='red')
)
pl.plot(scatter, name="CustomScatter3d")

pl.show()
