Adaptable splatting for irregular volume rendering
By employment of a footprint table in conducting intensity integration, splatting method has been very successful in rendering regular data volumes. Recently, the method has also been extended to render il regular data volumes. However, since samples in irregular volumes vary gleatly in size and shape, the footprint table is unable to be employed in an efficient manner. This hinders the application of splatting approach from being used in the irregular volume case. In this paper, an adaptable splatting method is proposed, which provides an efficient way to integrate color intensity in terms of footprint table Soi the samples in various sizes. Experiments show that the new method may be used to produce better images without extra expense.
