 ===== Instancing / Model duplication =====
+==== Instanced Rendering ====
+Since 0.8.3.2265 instanced rendering of the same mesh for x-times was implemented.
+Use this method to render for example grass or trees. It is not recommended to use it for animated charaters,
+because they would be rendered the same (with the same animation frame).
+You can simply setup instanced rendering in your TGorillaModel or TGorillaMesh object.
+<file pascal>
+/// we create 4 instances in a row
+GorillaModel1.AddInstance(TMatrix3D.CreateTranslation(Point3D(-10, 0, 0)));
+GorillaModel1.AddInstance(TMatrix3D.CreateTranslation(Point3D(-5, 0, 0)));
+GorillaModel1.AddInstance(TMatrix3D.CreateTranslation(Point3D(5, 0, 0)));
+GorillaModel1.AddInstance(TMatrix3D.CreateTranslation(Point3D(10, 0, 0)));
+/// afterwards we can modify a specific instance
+var LTransf : TMatrix3D;
+LTransf := TMatrix3D.CreateScaling(Point3D(2, 2, 2));
+LTransf := LTransf * TMatrix3D.CreateRotationY(DegToRad(90));
+LTransf := LTransf * TMatrix3D.CreateScaling(Point3D(2, 2, 2));
+GorillaModel1.Instances[2] := LTransf;

+==== Instancing by TModelDef ====
 Since 0.8.3.1966+ we've refactored the way to instanciate models. The previous method was incomplete in handling animated models.
