High Performance GPU-Based Fourier Volume Rendering

Figure 9

Results of rendering an axial projection of the visible male dataset with basic interpolation filters supported by OpenGL 3D textures. In (a), the projection of the dataset is orthogonal and the replicas are not shown. In (b) and (c), the volume is rotated and the ghosting artifacts are very apparent in (b) if a nearest-neighbour interpolation scheme is used and highly reduced if a trilinear interpolation filter is applied as shown in (c). Applying trilinear filtration on the spectral slice significantly affects the rendering performance if the slice size is greater than .
