Using the Ray History Sensor on Surfaces in LucidShape
LucidShape’s powerful Ray History Sensor is typically used to investigate the geometrical light path in a design from the source to the candela sensors to backtrack glare and other problems in the beam patterns. But you can also assign a Ray History Sensor to a surface to find out how rays pass through it or how they travel to a specific surface in your optical model.
This can be helpful for diagnosing anomalies in a design such as light leakage at a mounting feature, or to determine if changing the light engine can be a solution to reduce localized light loss in your design, or simply to verify that rays trace through your design as expected. The following figure shows ray paths restored on two pillows of an edge light design, highlighting the contributions from only two of the available sources.

The next time you ask, “Where are these rays coming from?” you can use a Ray History Sensor to provide the answer. Open the Assign Material dialog and create a sensor shape with the Ray History Sensor material. Create another surface sensor (e.g., a lux sensor) on the same geometry, and then restore rays from ray history sensor, just as you would if the rays were tracing to a candela sensor.

Modeling Customer Surface Roughness with LucidShape 2D Scatter Curve BSDF Material
LucidShape accurately simulates how light interacts with a surface using surface materials that define interactions in terms of reflection, transmission, absorption and scattering. Because all surfaces scatter light to some degree, surface materials also provide a way to specify a scattering distribution, which is necessary to achieve the most accurate optical simulations.
Surfaces in LucidShape can be of specular (i.e., ideal) quality with no scattering, or you can assign to them any of the available scattering material properties -- Gaussian or Lambertian scattering, user-defined scattering with a table of measured values, scattering based on a 2D scatter curve, and many more.
