Hi, Oliveira, 
    I am not sure what exactly is causing the problem, but maybe it is the setVertexArray(). U should call VertexArray::dirty(),after you changed data in osg::Array at runtime, to tell the OSG to update corresponding data in the GPU memory.

However, when I do this, I can see my points, BUT when I try to manipulate my scene with the mouse, the data disappears if I zoom in, and appears again if I zoom out again.

This seems like my node's bounds are not well set, But I manually verified all node's bounds and they are correct....

Any idea?
