JHZ-CS Space achieves this by generating a series of objects including a Star, Planets, Moons, Astroid Belts, Planetary Rings; as well as, a grid and mapping of planetary orbits. Potentially, supporting multiple Star systems each with their own orbiting objects; although, these objects are not part of this demonstration. The canvas is the Universe. Our Sun is the star. The planets and moons are part of our Solar System.
Displaying 3 dimensional representation in 2 dimensional space requires position coordination to place objects behind objects in front. Each display interval requires determine if an object is in front of other objects and display the object in the back before objects in the front.
Dynamically modifying object parameters requires linking user interface controls to virtual objects and generating vectors in real-time as needed. Here there is a option to pre-generate vector arrays, then simply move through the vector array, or calculate vectors at each display cycle. The number of operations occurring simultaneously demonstrates capabilities to emulate 3 dimensional representation using 2 dimensions. The X Y axises is complemented by the Z axis to determine position and relative size; closer to front an object is the larger it appears. It appears complex and exhaustive, but actually it is merely a series of simple processes combined to create a complex representation.
