Editing Appendix/Ramblings/RiemannMeetsOculus (section)

==Preamble==

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 the [[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 a [[Appendix/Ramblings/OculusRiftS#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.  [[Appendix/Ramblings/OculusRiftS#Summary|Toward the end of this separate discussion]], we provide the full COLLADA code &#8212; in a plain text format &#8212; 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 "&hellip; 45X" model &#8212; 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.
