Zooming Problem

[Eyal]

Hi All,

Sorry for my English....

When I'm using OrbitBehavior or MouseZoom  Behavior for zooming some object  some of it or all of it disappear
when I get closer. I want to get closer to the surface of the object with the mouse without any disappearing
any ideas please?

Thank u
Eyal

Is it possible that you zoom behind or into the mesh?

[Eyal]

I guess so, I mean when I zoom some parts of the mesh disappear

This is probably caused by the near clipping plane clipping away the parts of the mesh that are too near to the camera. What are your trying to do?

I'm trying to zoom into an object. There are 3D program that when you zoom you feel like y very near the surface of the object and you can see some feature of the object only when you are "on" it

You can zoom by modifying the viewing frustum. Multiply the left, right, top, and bottom values by a zoom factor. The lower the zoom factor, the higher the zoom and vice versa... But it might just be the near clipping plane...

I am under the impression that effect is achieved with different textures (if not a different mesh) for different distances from the object.  The closer you are, the more detailed the texture/mesh.

I guess you r right. How do I do that?
Thank u
