Imagine that you are a manufacturing engineer designing molds in which plastic is injected. You have software that analyzes your 3-D mold design and gives you the following information for any 3-D location within the mold:
¦ Temperature of the plastic
¦ Direction in which the plastic is flowing
¦ Velocity of the fl owing plastic
¦ Pressure of the plastic
Design a visualization, utilizing glyph markers, that depicts this information. Consider how color might be used to represent some of the dimensions, and how geometric shapes could be used for others. Make sure that the glyphs are modular; that is, if several locations along a line are sampled, the glyphs should be able to "stack" on top of each other.
