Hi,

I use the following graph :

Code:
Root
|
|---- Group_1 (node mask 0x7FFFFFFF)
|
|---- Group_2 (node mask 0x80000000)

Group_1 and Group_2 have childs, with node mask 0xFFFFFFFF :

Code:
Group_1
|
|---- Child_11 (node mask 0xFFFFFFFF)
|
|---- Child_12 (node mask 0xFFFFFFFF)

Code:
Group_2
|
|---- Child_21 (node mask 0xFFFFFFFF)
|
|---- Child_22 (node mask 0xFFFFFFFF)

But when I use osgViewer::View::computeIntersections like this :

pView->computeIntersections(x, y, intersections, 0x80000000)

Child objects of Group_1 are intersected... like if Group_1 children are traversed by the intersector

Is there any reason ? or did I miss something ?
