Hello -

I have a sphere inside another sphere... I have the out side sphere cut a slight amount to show the inner sphere. The problem I am having and it may be with my settinggs, but at a certain distance I can see the inner sphere showing through the outter... is ther ea way to dampen this or stop it all together?

thanks

Previously, when the 'object detail' setting slider was put to the maximum, it was barely noticeable. Now we no longer have a choice, since a maximum setting still does a terrible job of rendering curved prims at a distance.

At a certain distance, the SL client will reduce the sphere into something with lesser polygons to speed things up for the user. So things shart to show through.

The most you can do at the moment is make the outer sphere larger than the inner one.

This is assuming you aren't using alpha textures on the prims, because those introduce another set of problems.

The post above me is correct, but see also z-fighting, which exists in SL too and can cause similar problems.

Visual estimates suggests to me that SL often draws circles as 24 lines. The mathematically inclined could calculated the minimum size difference needed to ensure that two nested spheres never intersect in the display (not that they should, but...)

if your using cut, why not make the other sphere cut too? that way they don't overlap.
