Rendering is the process of producing high-quality output images and movies of the loaded dataset for publication and other purposes. The rendering page of the command panel depicted in the screenshot lets you control various settings related to image and movie generation. Furthermore, OVITO provides several different rendering engines, which are listed in the following table and differ in terms of visual quality and speed.

Rendering engineDescription
OpenGL rendererHardware-accelerated renderer, which is also used for realtime display in the interactive viewports
Tachyon rendererSoftware-based raytracing renderer, with support for ambient occlusion lighting, shadows and depth of field
OSPRay rendererAnother highly optimized software rendering engine with similar features as the Tachyon renderer but reduced memory requirements
POV-Ray rendererThis engine automatically invokes the external POV-Ray software to render OVITO scenes
