Poor resolution in animation

Hello I have a data set (polydata) rapresent a polymer (Molecules) I use a sphere glyph for the molecule and filter tube for the line rappresenting the virtual string that connect the Molecules each others … I try to make an animation using the Camera follow data … but I got a problem due to the resolution (Don’t know if is the named properly) btw the problem is that some times due to the position the sphere disappears …
how can I improve or ideally avoid this situations ? please heve a look to the pictures


I think I solve the problem setting “Display geometry rappresentation” Glyph mode : “all points”
