Synopsis |
An introduction to digital images and audio and their uses in 3-dimensional computer graphics. |
|
Description of Class |
This lesson gives an introduction to the use of digital media.
The students will learn how and why digital images are used in 3-dimensional computer graphics, and delves into texture mapping in computer graphics.
Digital images are explained as 2-dimensional arrays of colored pixels. A pixel is defined as a triple of numbers representing red, green, and blue intensity values.
The aspect ratio of an image is defined and discussed.
The basic paradigm of texture mapping is explained. Examples are given of mapping textures in various orientations onto a variety of polygon-based models.
The students are introduced to a software tool to map their own images, created in Corel, into a pre-defined virtual world.
The students use a related tool to attach sound files to objects in the virtual world. |
