Embedded B-spline Reconstruction in the Volume Rendering

This paper deals with reconstruction problem in the visualization. The representation of the object is based on the volumetric data. Volumetric data is sampled on a regular grid. The surface of the object is implicitly defined as a zero value of the volumetric function. In the volume rendering procedure, intersection of the cast ray with the object is required. Trilinear interpolation is usually used for the reconstruction. In this paper we propose interpolation B-spline embedded directly into the rendering procedure. Different artifacts may appear due to the reconstruction in the rendering procedure. If the quality of the rendered object is of the crucial importance we have to pay attention on the reconstruction in the rendering procedure.
