Hello,
wandering around the U++ documentation I have some quastion I did't find an answer:
1) What is exactly Rainbow? And why on the Example section of the side there are two examples (FrameBuffer, UWord_FB) but in the U++ Package no?
2) Painter is amazing... really impressed (not too difficult since I'm a numeric calculus C programmer for the most).
There is some benchmark compared to other Vector Graphic framework? (like Adobe, Quartz, OpenVG, Cairo, etc).
I read some topic on the forum about hardware accelerated Vector Graphic.
Well, first I would say that with the advent of shader everything can do by a CPU can be do also by a GPU,
perfomance consideration came later and maybe there can be situation where CPU is more performant.
I find this recent article: https://developer.nvidia.com/gpugems/gpugems3/part-iv-image- effects/chapter-25-rendering-vector-art-gpu
and there the question: there is some idea to make painter hardware accelerated? Someone is thinking about that?
3) I read somewhere of hardware accelerated Draw so there is a GL U++, where can I found more about that?

Thank you
Silvan
