Christina Powell 3D Graphics Modeling, Planetary system Period 5 Oct. 3 - Processing language not currently working, currently learning OpenGL - starting with rotating square. Oct. 5 - portraying a sphere, lighting in 3D rendering Oct. 7 - on a field trip Oct. 14 - comparing the graphical languages OpenGL and Processing. Will try displaying the same image in each. Oct. 19 - Oct. 21- Using Processing, can translate her project into an Applet so we can view this. Nov. 4 - website Dec. 14 - Current Status Update Currently my model consists of a single planet orbiting the Sun. I am attempting to make this model physically accurate using Newton's Law of Gravitation, the laws of projectile motion, and the leapfrog algorithm. My program is currently suffering from calculation errors which I am methodically attempting to locate and fix. Once I perfect this method, I will be able to add texture to the planets and the Sun, program more user interaction, and perhaps add other heavenly bodies such as comets and asteroids.
