Making the Applications
Interesting
This chapter discusses some mathematics background and advanced computer
graphics concepts that allow the building of more intelligent and visually appeal-
ing applications. This chapter:
• presents the mathematics to orient and move objects toward any given di-
rections/positions;
• explains the basic ideas of simulating transparency with alpha blending;
• describes the essential concepts and procedures of working with file texture
mapping.
After this chapter we should:
• understand simple and practical applications of vector dot products and
cross products;
• understand the basic concepts behind alpha blending and file texturing.
In addition, with respect to hands-on programming, we should:
• be able to program the motion of objects to follow and/or home in on any
position;
