This update introduces support for a third dimension (Z-axis) in scene
positioning and orientation, enhancing 3D scene rendering capabilities.
Changes include parsing the Z-coordinate attribute in scene elements,
updating the `loadScene` function to accommodate the new axis, and
extending the models to store this additional data. This pivotal
enhancement allows a more refined and immersive user experience by
enabling depth control in scene navigation and interactivity. The
modification paves the way for future developments in 3D scene
manipulation and interaction within the application.
