Mesh Import & Visualization
Import and visualize large meshes from external mesh generation tools.
This tutorial demonstrates how to import and visualize large meshes from external mesh generation tools.
Mesh view of Model.
# Import necessary modules
import sys # Provides access to system-specific parameters and functions
from PySide6.QtWidgets import QApplication, QMainWindow # Import Qt widgets for GUI application
# Import IGLGraphics modules for display context and viewer
from IGLGraphics.core.IGLDisplayContext import IGLDisplayContext
from IGLGraphics.graphics.IGLViewer import IGLViewer
from IGLGraphics.geometry.IGLImport import IGLImport
# Create the QApplication instance,
# which manages the application's control flow and main settings
app = QApplication(sys.argv)
# Create the main window of the application
win = QMainWindow()
# Set the title of the main window
win.setWindowTitle("IGLGraphics CAE Test")
# Create an instance of IGLViewer, which is a IGLViewer widget for
# displaying models and handling user interactions
view = IGLViewer()
# Create an IGLDisplayContext associated with the viewer, for managing graphics rendering context
thecontext = IGLDisplayContext(view)
#
importer = IGLImport()
filename = r'Saddle.msh'
is_valid, MeshData = importer.ImportMesh(filename)
# Add the mesh data structure to the display context for rendering
if is_valid and MeshData:
thecontext.AddMesh(MeshData,True)
# Set the central widget of the main window to the IGLViewer
win.setCentralWidget(view)
# Resize the window to 800x600 pixels
win.resize(800, 600)
# Show the main window
win.show()
view.OnZoomFit() # Adjust the view to fit the entire model in the viewport
# Start the application's event loop and exit when it finishes
sys.exit(app.exec())
