Downsampling and Storage of Pre-Computed Gradients for Volume Rendering [article]

Jesús Díaz-García, Pere Brunet, Isabel Navazo, Pere-Pau Vázquez
2017 Spanish Computer Graphics Conference (CEIG)  
The way in which gradients are computed in volume datasets influences both the quality of the shading and the performance obtained in rendering algorithms.  ...  An obvious solution is to pre-compute the gradients and store them. Unfortunately, this originates two problems: First, the downsampling process, that is also prone to generate artifacts.  ...  Introduction The visualization of volume datasets by means of volume rendering algorithms is a demanding task that requires a high degree of computational power and resources.  ...

Approximating the Bandwidth via Volume Respecting Embeddings

Uriel Feige
2000 Journal of computer and system sciences (Print)  
Our algorithm is based on a new notion, called volume respecting embeddings, which is a natural extension of small distortion embeddings of Bourgain and of Linial, London and Rabinovich.  ...  Computing volumes Theorem 3 shows that Vol(S) can be approximated within a factor of 2 (jSj?2)=2 in polynomial time, by computing Tvol(S).  ...  We wish to compute Vol(S). For the tree G (and hence for the tree metric space (S; d)), we introduce a notion of tree volume that is de ned as Tvol(S) = n i=2 i .  ...

Rigidity and Volume Preserving Deformation on Degenerate Simplices

Lizhao Zhang
2017 Discrete & Computational Geometry  
sufficiently small motion must preserve the volumes of all k-faces; and this property still holds in M^d for d≥ n+1 if an invariant c_k-1(α^k-1) of the degenerate simplex has the desired sign.  ...  We prove that if the vertices of the simplex vary smoothly in M^d for d=n, and the volumes of k-faces in one subset are constrained only to decrease while in the other subset only to increase, then any  ...  In the computation of the volume of the simplices in S n and H n , we find an interesting application of the Schläfli differential formula.  ...
