Projections and Reformations
Abstract
In medical visualization, there are a number of mapping techniques that are employed to reduce 3D data, either by projection or reformation, to effective 2D visual representations. Straightforward projection, as employed in the standard 3D graphics pipeline, also serves to reduce 3D data to a 2D representation. However, in this chapter we discuss examples that go a step further in terms of complexity and effectiveness.
We have classified these reductive techniques broadly into two groups: projections and reformations. In projections, 3D information is accumulated, or flattened, along one or more directions to obtain a 2D image. In reformations, 3D information is sampled along some geometry that ...
