Hello,

I have used Kerkythea quite a while ago, and I am not sure what bits of code they share, that would be a question for the Thea forums. I also can't speak to performance differences, although I can say I have a good idea of what the image is going to look like inside one minute with the unbiased engine and even less time with the interactive render. I think I will end up getting Motiva Colimo on special to use alongside Thea, it looks great for product design and architecture.
