Every few months (or years) I look for other lighting designers, optomechanical engineers, etc, that are using or have used add-ins for ray tracing. There are a couple of new add-ins out there and so I thought I'd ask again. I am using OptisWorks with the LM2 lighting and OD optical design packages plus the colorimetry, phosphor down conversion (mass/bulk scattering), and 3D Textures add-ins with the 16 thread option. Is anyone else using OptisWorks and if so what packages and what has been your experience?

I am also using the Zemax LensMechanix Add-in. This is a new software geared toward the optomechanical engineer specifically. Anyone take advantage of the trial or beta programs?

How about the Lamda Research software? I am interested in the new RayViz Add-In. Anyone using the early adaptor program software?
