Quick Tip


NURBS Curves in LightTools


LightTools provides numerous modeling aids such as solid modeling, Boolean operations, reference geometry, etc. Included with the reference geometry tools are non-uniform rational basis spline (NURBS) curves. NURBS curves can enhance your workflow in many ways, and they can also be used for purposes such as optimization. You can access the NURBS curve tools by selecting the menu Insert > Reference Geometry or clicking 2D Objects > Draw Line on the command palette.



What is a NURBS curve?


You can find a good description of NURBS curves here: https://en.wikipedia.org/wiki/Non-uniform_rational_B-spline


While the mathematical aspects of NURBS curves can be difficult to understand, LightTools presents them in a simple way for modeling needs. No extensive knowledge of NURBS curves is necessary to use them in LightTools. A NURBS curve exposes a series of control points that can be used to change the shape of the curve.

“Effects of individual particulates in optical systems using a spatially isolated contamination scattering method” live at SPIE Optics and Photonics


Katherine Calabro of the Synopsys LightTools team will present a talk detailing the paper “Effects of individual particulates in optical systems using a spatially isolated contamination scattering method,” co-authored with Mike Zollers.


This presentation will discuss the standard developed by the Institute of Environmental Sciences and Technology (IEST) most commonly used to define the typical sizes and density of particulates on a surface. This standard can then be used to create a BSDF profile of the contaminated surface and simulate the effects of the contaminants. This approach is limited by scattering events that occur stochastically, with no spatial consistency. In this work, a more realistic modeling approach is examined, considering particulates to be stationary, it is possible to isolate the effects of an individual particle, which can be especially useful for small scale systems. A variety of application designs are investigated through the use of computer simulation to demonstrate the advantages of the isolated contamination scattering approach.


Attend this live talk August 13, 2019 at 11:50 a.m. in the “Novel Optical Systems” conference at SPIE Optics and Photonics, located in the San Diego Convention Center.
