traversal state before traversing its children and a pop (restore) after traversing them. This isolates the separator's children from the rest of the scene \&graph. A separator can include lights, cameras, coordinates, normals, bindings, and all other properties. Separators are relatively inexpensive, so they can be used freely within scenes. .sp The \*(CbSoSeparator\f1 node provides \&caching of state during rendering and bounding box computation. This feature can be enabled by setting the \*(CbrenderCaching\f1 and \*(CbboundingBoxCaching\f1 fields. By default, these are set to \*(CrAUTO\f1, which means that Inventor decides whether to build \&a cache based on internal heuristics. .sp Separators can also perform culling during rendering and picking. Culling skips over traversal of the separator's children if they are not going to be rendered or \&picked, based on the comparison of the separator's bounding box with the current view volume. Culling is controlled by the \*(CbrenderCulling\f1 and \*(CbpickCulling\f1 fields. These are also set to \*(CrAUTO\f1 by default; however, render culling can \&be expensive (and can interfere with render caching), so the \*(CrAUTO\f1 heuristics leave it disabled unless specified otherwise. .SH FIELDS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(CrSoSFEnum .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbrenderCaching .br .in 1i \f1Whether to cache during rendering traversal. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(CrSoSFEnum .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbboundingBoxCaching .br .in 1i \f1Whether to cache during bounding box traversal. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(CrSoSFEnum .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbrenderCulling .br .in 1i \f1Whether to cull during rendering traversal. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(CrSoSFEnum .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbpickCulling .br .in 1i \f1Whether to cull during picking traversal. .sp .in 0.5i .SH METHODS .ta 20m .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbSoSeparator\*(Cr() .br .in 1i \f1Creates a separator node with default settings. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Cr .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbSoSeparator\*(Cr(int nChildren) .br .in 1i \f1Constructor that takes approximate number of children. .sp .in 0.5i .in 1i+20n .ti 0.5i .ta 20m .ds Pt \*(Crstatic void .ie \w'\*(Pt'>=20n \{\ .ne 3 \*(Pt .ti 0.5i \c\ \} .el\{\ .ne 2 \*(Pt \c\ \} \*(CbsetNumRenderCaches\*(Cr(int howMany) .br .in 1i \f1By default, each separator node maintains 2 render caches. (This is to allow two different representations, such as filled and wire-frame, to both be cached.)

Each render cache uses memory, so increasing this number may increase the memory requirements of the application. This method affects only separators that are created after it is called, \¬ separators that were created before.
