Ray Trace Rendering

Choosing your Ray Trace Renderer in VStitcher/Lotta

3D Window and Ray Trace Rendering Output - What's the Difference?

The output in the 3D window is generated more quickly than ray trace rendered output. A ray trace render takes more time because it produces more detailed output that mimics how light works in real life and is much more realistic. Further, it adds information that isn’t seen in the 3D window, such as self-shadowing, environment shadows, color bleed, and more. The main difference is not so much in the explicit colors as the tones displayed with, for example, shadows darkening the image and color bleed having a subtle effect.

  • 3D window output is quicker to display and is suitable for most workflow tasks.

  • Ray trace rendered output is more accurate and best for final design decision purposes.
