LucidShape Quick Tip: Using Clipping Planes to Reveal Ray Paths

When you’re analyzing a complex optical design, it’s important to be able to follow the ray paths to observe how rays interact with all relevant shapes. This can be cumbersome to do when surfaces are displayed in Wireframe, but if you switch to Shaded display, the shaded geometry blocks your view into the simulation model.

Did you know that it’s possible to see the light flow inside your design in Shaded mode? Of course it is – with a clipping plane!

  • Create one or more clipping planes to clip away any geometry obstructing your view without affecting your model or its ray tracing properties.
  • Combine interactive ray trace with a clipping plane to “cut” your geometry open and get a good look inside.
  • If you want to keep the clipping plane in the model to use repeatedly, you can make it invisible until you need it again.

To create a LucidShape clipping plane, select the menu Geometry > Create Clipping Plane.
