Reconstruction of volume data with quadratic super splines

C. Rossl, H.-P. Seidel, F. Zeilfeider, G. Nurnberger
2004 IEEE Transactions on Visualization and Computer Graphics  
Our results confirm the efficiency of the quasi-interpolating method and demonstrate high visual quality for rendered isosurfaces.  ...  As a model, we use quadratic trivariate super splines on a uniform tetrahedral partition.  ...  Our approach allows efficient and high-quality visualization of volume data, which we illustrate by rendering isosurfaces of well-known synthetic and measured test data sets using raycasting.  ...

INTERACTIVE IMPLICIT MODELLING BASED ON C1 CONTINUOUS RECONSTRUCTION OF REGULAR GRIDS

LOIC BARTHE, BENJAMIN MORA, NEIL DODGSON, MALCOLM SABIN
2002 International journal of shape modeling  
We show how accurate and high quality interactive visualisation is obtained during the modelling process, and we explain why the visualisation is faithful to the object definition.  ...  We also describe, as an example application of our data structure, how advanced Boolean operators realised with soft or free-form transitions are performed under the influence of an interactive modelling  ...  A useful solution can come from a triquadratic filter (trivariate quadratic B-spline) that allows interactive renderings [37] with a high quality reconstruction ( Figure 1 ).  ...

The computed normals are used for Gouraud shading, which enables high quality rendering after a small number of subdivision iterations (two instead of five).  ...  It is further possible to extract high quality isolines and -surfaces.  ...  It is based on surface splines, a representation for C1 manifolds that generalizes B-splines to meshes with polyhedral connectivity, allowing n-valent mesh points and m-sided facets.  ...
