Decimating Gollum

He presented a seminar for our undergraduates and also spoke about 3D printing with the public school teachers in my Charlotte Teachers Institute (CTI) seminar.

Suddenly, your friend turns and comments, “Did you know that the average person at this game is a millionaire?” How would you respond? Who did your friend see in the stands?

Adding some texture

In the last post, we began a series on creating computer graphics with POV-Ray. In that post, we constructed balls of various solid colors like that below. Now, let’s wrap textures around them.

Become your own Pixar

Computer generated images are created, as clearly indicated by their name, on computers. How do computers generate such lovely pictures? A key is math modeling – underneath such programs are models of the physical world that determine the color of a pixel on the screen based on the light and the physical characteristics of the […]
