abstract = "In this paper we explore the architecture of GPU-based volume
ray-casting to control the cursor movements on surfaces of volume
data only on the basis of their sampled scalar values. This method
does not rely on building a tight proxy geometry nor computing
local iso-surface parametrization. In this setting only a few
instructions should be included in a ray-casting shader: at every
fragment the depth of the closest non-transparent voxel along each
viewing ray is calculated and stored in the depth buffer. Its
application in the manipulation of 3D medical images has, however,
a broad spectrum. Two of them are presented. The proposed
technique is very simple and fast, yet produces very nice and
intuitive visual feedbacks.",
