The viewport and the graphics processor

Meridian draws the model with OpenGL. On Windows, it uses ANGLE with Direct3D 11. On Linux, it uses EGL or GLX. If hardware drawing is not available, Meridian uses a software renderer.

Autosave and recovery

Meridian has autosave and recovery. It saves your work at intervals, so that you can recover it if Meridian stops unexpectedly.

Plugins

To see the plugin trust decisions, select Tools > Plugins. On Linux, Meridian trusts plugins in /opt/meridian/plugins/ and ~/.local/share/Meridian/Plugins/.

Settings folders

On Linux, Meridian keeps its settings in ~/.config/Meridian and its data in ~/.local/share/Meridian.
