This view displays the five basic parts of the dome: the hemispherical dome [red], the parametric base cone and parametric main cone [yellow], the trapezoidal layer [aqua], and the cylinder [royal blue]. This image represents a simplified model based on the side-elevation from reference 1 and was created for a comparison study on optical illusion.

This view is also based on the skeletal side-elevation from reference 1. In this model, the main and base cones have been replaced by the six triangle [purple and royal blue] that make up the interior design of the dome.
