# OpenGL renderer

This is the default built-in rendering engine, which is also used by OVITO for rendering the interactive viewports.

## Parameters

Anti-aliasing level

  To reduce aliasing effects, the output image is usually rendered at a higher resolution than the final image (supersampling). This factor controls how much larger this resolution is. A factor of 1 turns anti-aliasing off. Higher values lead to better quality.
