 ===== FrustumCulling =====
+The viewing frustum is a geometric representation of the volume visible to the virtual camera. Naturally, objects outside this volume will not be visible in the final image, so they are discarded.
+[[https://en.wikipedia.org/wiki/Hidden-surface_determination#View_frustum_culling|Source:https://en.wikipedia.org/wiki/Hidden-surface_determination#View_frustum_culling]]
+This is a great boost to the performance of your application, when only objects will be rendered that would be visible.
+The FrustumCulling property enables or disables the functionality in general.
+But you can activate/deactivate it for each derived type of TGorillaControl, by setting:
+<file pascal>
+GorillaCube1.FrustumCullingCheck := false;
+</file>
+If FrustumCullingCheck is set to FALSE, it will always be rendered, wether it's inside or outside of the view frustum.
+Take care, that the frustum culling may affect render-passes, where a different view matrix is used.
