Hi Michael,

now it's all clear. Thank you for your comprehensive answer!

I understand your technical point of view...you prefer to be independent from any particular hardware requirements,
and do all the tasks leveraging on the cpu rather than any type of gpu.

From what I've read here and there on the web, i'v seen that there are two main approaches to display 3d graphics models in realtime.

Someone prefer to squeeze the gpu up to its limits, while others
say that the tasks that a cpu can accomplish are more accurate and reach better results.

I'm sure that whatever approach you will adopt for V4, it will be a good compromise between speed and quality,
(also winking at a better antialiasing quality :)

Have a good work,

Marco.
