A computer can identify discrete objects within a 3D geometry in a vector-based format. The computer can compare a spatial property of each of the discrete objects against an established spatial range. From the comparing, the computer can determining that a set of the discrete objects have a spatial property within the spatial range. The computer can omit the discrete objects from the 3D geometry as a group to create an altered 3D geometry. The computer can submit the altered 3D geometry to a render engine for display. The number of polygons in the altered 3D geometry is less than the number of polygon faces in the 3D geometry.
