\fBSoGetPrimitiveCountAction\fP class counts the primitives in a scene\&. Apply this action to a scene if you need to know the number of primitives present in a scene graph, or parts of a scene graph\&. .PP One common mistake to make when using this action is to think that it traverses just the parts currently in view, like \fBSoGLRenderAction\fP does\&. (\fBSoGLRenderAction\fP culls away the scene graph parts outside the camera view volume and does not traverse those\&.) Like most other action classes, \fBSoGetPrimitiveCountAction\fP actually traverses the complete scene graph, not just the parts currently in view\&. .PP \fBSince\fP .RS 4 Coin 1\&.0 .PP TGS Inventor 2\&.5 .RE .PP .SH "Constructor & Destructor Documentation" .PP .SS "SoGetPrimitiveCountAction::SoGetPrimitiveCountAction (void )" Constructor\&. .SS "SoGetPrimitiveCountAction::SoGetPrimitiveCountAction (const \fBSbViewportRegion\fP & vp)" Constructor\&.
