An engineering design graphics course would have a heavy emphasis on projection theory, for example. Visual Science Knowledge Base Geometry Geometry is the branch of mathematics that deals with the properties, relationships, and measurements of points, lines, planes, and solids. See Figure 3. Plane geometry is concerned with planar figures, such as circles and polygons, and their relationships. Solid geometry is concerned with three-dimensional objects, such as cylinders, cones, and cubes, and their relationships.
Descriptive geometry is concerned with analyzing and solving space distances and relationships.
Much of the study of engineering design graphics has dealt with these topics. However, it must be recognized that the study of geometry has a much wider application than just engineering. Artists, animators, illustrators, and anyone who creates graphics has a need to learn about geometry. It is through scientific inquiry that disciplines move forward and new knowledge is discovered. In visual science, research is conducted in cognitive visualization, imaging, and geometry.
