3d flow around object

[Alexey1978]

Hi,
I have the following task.

There is given 3d vectorfield around object (liquid fluid or gas flow). How can I visualize it with help of Qt like a flow. Should I use Qt 3D Render or are there another objects?

And is there any example code using 3D Render with 3D big data, or other examples using user defined image data.

Thanks a lot.
