Splatting of Curvilinear Volumes

چکیده
This paper presents a splatting algorithm for volume rendering of curvilinear grids. A stochastic sampling technique called Poisson sphere/ellipsoid sampling is employed to adaptively resample a curvilinear grid with a set of randomly distributed points whose energy support extents are well approximated by spheres and ellipsoids. Filter kernels corresponding to these spheres and ellipsoids are used to generate the volumerendered image of the curvilinear grid with a conventional footprint evaluation algorithm. Ezperimental resulta show that our approach can be regarded aa an alternative to existing fast volume rendering techniques of curvilinear grids,

Splatting Errors and Antialiasing
This paper describes three new results for volume rendering algorithms utilizing splatting. First, an antialiasing extension to the basic splatting algorithm is introduced that mitigates the spatial aliasing for high-resolution volumes. Aliasing can be severe for high-resolution volumes or volumes where a high depth of field leads to converging samples along the perspective axis. Next, an analy...

Splatting is a popular direct volume rendering algorithm that was originally conceived and implemented to render orthographic projections. This paper describes an anti-aliasing extension to the basic splatting algorithm, as well as an error analysis, that make it practical to use for perspective projections. To date, splatting has not correctly rendered cases where the volume sampling rate is h...
متن کاملEfficient Splatting Using Modern Graphics Hardware
Interactive volume rendering for data set sizes larger than one million samples requires either dedicated hardware, such as three-dimensional texture mapping, or a sparse representation and rendering algorithm. Consumer graphics cards have seen a rapid explosion of performance and capabilities over the past few years. This paper presents a splatting algorithm for direct volume rendering that ut...
متن کاملSkeletonization and Distance Transforms of 3D Volumes Using Graphics Hardware
We propose a fast method for computing distance transforms and skeletons of 3D objects using programmable Graphics Processing Units (GPUs). We use an efficient method, called distance splatting, to compute the distance transform, a one-point feature transform, and 3D skeletons. We efficiently implement 3D splatting on GPUs using 2D textures and a hierarchical bi-level acceleration scheme. We sh...
