Right now Caustic Graphics is catering towards animators and architects, but eventually they'll be offering up products to improve the graphics and ray-tracing capabilities for gamers. On their web-site they hadn't mentioned whether they intend to support their products under Linux, but this evening we can confirm they will indeed provide this operating system support.
Caustic Graphics had told Phoronix, "Letting you know that we will be supporting Linux. A number of film studios are using Linux for their rendering pipeline, so we felt it was a must have for our CausticRT. The first generation of our technology is targeted toward developers and Independent Software Vendors (ISVs). When we reach our next generation in 2010, we expect a number of commercial rendering packages to be available that support our technology."
No word was given whether their Linux support will be open-source, but given their current targets, we anticipate it being a binary blob. When we have more information on Caustic Graphics and Linux, we will be sure to share the news.
