Hi All,

I am facing problem in displaying the large number of objects of the same kind on the view. I tried displaying the 25K vertex objects on the view by creating the BRep_API Make Vertex and its throwing crash after displaying around 18K. Can anybody suggest how to rectify the problem of crash for displaying the large number of objects ( Vertex) of the same kind ...nearly 1 lakh objects....

Thanks in Anticipation,
Vijay

Hi Vijay,

try creating your own AIS_InteractiveObject. You can find an example in the User_Cylinder.cxx in the OC samples.

Thanks Pawel,

I have created a separate interactive object of our own and tried displaying it. Even facing the same problem.

Hi Vijay,

you don't try to display 25 000 your customized objects, do you?

The trick is to make one AIS_InteractiveObject displaying many objects. I managed to display 10 million points that way (or even more, I'm not sure right now).

Regards
Pawel

Hi Pawel,

I have created my own Interactive Object class and presented all the points in the same object and add the selection primitives for all the points. But problem here is, i am not able to select each point individually and all the points are selected as a whole. By having all the points as a single interactive object, can we able to select each point individually?
