....the ray traversal. Applying these acceleration methods the rendering time can be reduced significantly, but the frame rates are still far from interactivity. Although there are surface oriented algorithms which provide real time rotation, their limitation is the lack of the opacity manipulation [17][18] 2 The Algorithm The software only acceleration technique presented in this paper can also be considered as a surface oriented algorithm since interactive frame rates can be achieved if the opacity function is binary or near binary (the non zero opacities are near one) On the other hand ....

....surface points are converted to geometrical primitives which are rendered by conventional graphics hardware. Saito[16] used the same strategy converting only a subset of the surface points to geometrical primitives, where the samples are selected according to a uniform distribution. Choi and Shin[14] worked out an efficient image based surface rendering method which provides interactive frame rates without any specialized hardware. The limitation of their approach is the lack of the basic volume operations such as cutting. Real time rotation can also be achieved applying an incremental binary ....
