	Here — as one specific example — we will continue to focus on the ''direct'' (as opposed to the ''adjoint'') S-Type Riemann ellipsoid whose axis ratios are b/a = 0.41 and c/a = 0.385. Additional physical properties of this configuration are detailed in an [[~~User:Tohline/~~Appendix/Ramblings/VirtualReality#Step-By-Step_Production\|accompanying discussion]].

	Let's add the wall clock and alpha-numeric identification of the model's parameters.

	In an [[~~User:Tohline/~~Appendix/Ramblings/VirtualReality#Virtual_Reality_and_3D_Printing\|accompanying discussion]], we have illustrated how an animated, interactive 3D scene can be largely defined via the xml-formatted language named [https://www.khronos.org/collada/ COLLADA]. In the [[~~User:Tohline/~~Appendix/Ramblings/VirtualReality#Step-By-Step_Production\|last major subsection of that discussion]], we have outlined the steps that can be followed to specifically generate any of a variety of Riemann S-Type ellipsoids. These steps were identified within the context of our effort to construct 3D VR/AR models that could be faithfully rendered using the Mac's Preview app.		In an [[Appendix/Ramblings/VirtualReality#Virtual_Reality_and_3D_Printing\|accompanying discussion]], we have illustrated how an animated, interactive 3D scene can be largely defined via the xml-formatted language named [https://www.khronos.org/collada/ COLLADA].

	In a [[~~User:Tohline/~~Appendix/Ramblings/~~OculusRift_S~~#Success_Importing_Animated_Scene_into_Oculus_Rift_S\|separate but closely connected discussion]], we have demonstrated that most of our COLLADA-based models can be imported into the 3D virtual-reality environment of the Oculus Rift S. [[~~User:Tohline/~~Appendix/Ramblings/~~OculusRift_S~~#Summary\|Toward the end of this separate discussion]], we provide the full COLLADA code — in a plain text format — along with a summary description of a model that has been assigned the name, <font color="darkgreen">FullLast45X.dae</font>.

	Intially, we discovered that most of the Riemann S-Type ellipsoids that we developed while relying on the Mac's Preview app did not display properly within the Oculus Rift S environment. What we propose to do, here, is methodically re-construct a variety of our earlier models that were viewable in the "Preview" app in such a way that they are all viewable with the Oculus Rift S. We begin with this "… 45X" model — renaming it, <font color="darkgreen">RiemannBuild00.dae</font>. Step by step we will insert components of one of our previously constructed COLLADA-based models of an S-Type Riemann ellipsoid into a <visual_scene> that can be properly executed within the Oculus Rift S.
