Introduction; Sources of Bitmapped Images; Vector-Drawn Graphics; Comparing and converting; 3-D Computer Graphics: Modeling; Surface Definition; Scene Composition, Rendering; Conclusion.

During this presentation we will be taking a look into some other forms of graphics not mentioned in the first presentation. We’ll explore vector-drawn, 2-D and 3-D modeled graphics and how they are rendered and their guidelines of use.

Paint Programs; Digital Cameras; Clip Art; Screen Grabs.

Definitions. Rasterizing – vector graphics converted to bitmapped images.

The most popular ways of creating models are to use: Polygons; Splines; Metaballs; Formulas;.

Metaball modelling creates objects as combinations of elements called blobs, similar to clay. These blobs are variously shaped and are either positive or negative.
