3D Geometric Demonstration of Seasonal Changes
2019-04-25 04:29
This applet uses 3D geometry and vectors to simulate seasonal changes during Earth's orbit. Utilizing a sphere for Earth, poles, vectors, and surfaces, it demonstrates the geometric relationship between the sun's rays and the four seasons. It features 3D coordinates, parametric equations, and sequences, ideal for teaching solid geometry and vectors.
