Dear Experts,

when I visualize a relative large dataset by assemblying polydata into multi-block dataset, the result is like outline view, but when I interact with the view, the result is OK.

So I wander is there any limitation for cell/point number? see my dataset information below:

No. Please explain a bit more what you are doing.

Thank you Mathieu for your reply!

I try to visualize a Big tree, which is constructed by large number of small tree structures. so it is a Hierarchical Structure modeled by Multi-Block Dataset.

I found if sperate it into two tree, visualization result is correct, but if i combine all into a single tree(one Multi-Block Dataset) the visualization result rendered by surface representation just like outline representation result.

But when i interact with it, the result become correct again, and will become to “outline” when i stop mouse interaction. seems dynamic render is correct, but static render is wrong.

Thanks a lot!  
Sharon

Sounds like a treshold settings. Looks into your settings or reset them.
