Occlusion culling
3D AccuracyThe accuracy setting controls the tessellation of surfaces."Tessellation" means that the surfaces of your geometry are built using triangles. A triangulation is computed to describe the neighborhood relation of all points. You have two choices (the preview area to the right shows you the effect of each setting):
Level of DetailYou do not always need to view a high level of detail in your geometry all the time because some portions may be obscured by a visible piece of the model or be far enough away to make the detail meaningless. When this is the case, you can use the level of detail (LOD) mechanism. A LOD is an approximation of the mesh intended to reduce the number of polygonal objects in modeling. The purpose of the LOD mechanism is to adjust the polygonal representation of an object to the viewer distance. You can use the Static and While Moving settings to modify the display quality:
In both cases, the higher the value, the lower the level of detail. Normally, you set Static to a low value, and While Moving to a high value. The added value is increased display performance.
Pixel CullingThis option is similar to the Level of detail options, but in that case, it lets you define the size in pixels of objects to be hidden or displayed in your geometry using the Static and While Moving sliders.

PickingThis area enables you to pick elements, i.e. select elements when pointing them. In "normal" picking mode, you need to move your mouse to select an element whereas in accurate picking mode, the slightest move (one pixel, for instance) is enough to select.
