9月2日 的 Walter Bislin Flat Earth 3D 應用程式分析

The Walter Bislin Flat Earth model is intended to show the geometric and physical aspects of celestial events and observations. This is a 3D environment that allows you to rotate the camera using your touch screen, and under the input boxes in the bottom you can set the time, date, latitude, and longitude. The smaller observer grid is great for understanding how our perspective works.
