Launching the Virtuoso 3D Viewer

The Virtuoso 3D Viewer is currently used only to view a mesh created by the EMX simulator for an electromagnetic model created in the Electromagnetic Solver assistant. Therefore, you can open the 3D Viewer only after creating a model for simulation.

To create and open mesh for a model:

• Choose Open Simulator – Generate Mesh on the toolbar of the Electromagnetic Solver assistant.
  This command creates a mesh and saves it in a .vmesh file and then it launches 3D Viewer to display the generated mesh.
  If the mesh already exists, use the Open Simulator – View 3D Mesh command on the toolbar to open the most recent .vmesh file in the 3D Viewer.

The 3D Viewer is available in Virtuoso by default. It uses a MESA Software OpenGL driver that is included within Virtuoso.

To enable the 3D Viewer:

• Set the CDS_USE_OPENGL shell environment variable before running Virtuoso. This variable enables OpenGL, which is required to open the 3D Viewer environment.
• [Optional] Set the CDS_AUTO_NATIVE_OPENGL shell environment variable only if you want to use your own Linux-based OpenGL. This variable enables OpenGL, which is required to open the 3D Viewer environment.
• [Optional] Ensure that your X11 server supports the GLX extension that enables 3D graphics.
  Use the xdpyinfo utility to check whether the GLX extension is enabled:

  $ xdpyinfo | grep GLX
  => GLX

  If the GLX extension is enabled, xdpyinfo returns GLX. If not, refer to the user manual of your X11 server environment to learn how to enable the GLX extension.
