Hi,
I have a big volume/mesh and I only want to render part of it.
The part is defined in a small 3D box and only volume/mesh inside this box is rendered.
There are two situations: one is the data is too big to load into video memory and the other one is the data can be loaded into video memory.
For both cases, I just want to render the volume/mesh inside the box.
How to do this?
Thanks in advance.
