Thanks so much for your reply.
i thought of using LOD but my geometry is a bit complex so my 3D world contains 'IndexedFaceSet' elements. that is why the LOD will be hard to apply :-(
I'll appreciate your feedback about using 'VisibilitySensor' node
Cheers

I am trying to use 'VisibilitySensor' so that to hide some objects when they are at specific distance from the user. basically my model is big and I want to improve the CPU perofomance.
Id this possible. For example, if the user is very close to the object then the object is visible, if the user a bit far from the object then the object is hidden.

Use LOD node:
#VRML V2.0 utf8
LOD {
range [9,11]
level [
Shape {
geometry Sphere {}
}
Shape {
geometry Cone {}
}
Shape {
geometry Box {}
}
]
}
VisibilitySensor
