Splatting is an object-space direct volume rendering algorithm that produces images of high quality, but is computationally expensive like many other volume rendering algorithms. This paper presents a new technique that enhances the speed of splatting without trading of image quality. This new method reduces rendering time by employing a simple indexing mechanism which allows to visit and splat...

The new Fe71.2B24Y4.8 glassy alloy has been prepared in amorphous ribbon form via melt spinning and splat cooling. The high degree of sample homogeneity and structural quality of the ribbon is revealed by the observation of narrow linewidths in the spectra of the field derivatives of the absorbed microwave power in ferromagnetic resonance experiments. Combination of vibrating sample magnetometr...

We introduce a method for surface reconstruction from point sets that is able to cope with noise and outliers. First, a splat-based representation is computed from the point set. A robust local 3D RANSAC-based procedure is used to filter the point set for outliers, then a local jet surface – a lowdegree surface approximation – is fitted to the inliers. Second, we extract the reconstructed surfa...

We use experiments and minimal numerical models to investigate the rapidly expanding monolayer formed by the impact of a dense suspension drop against a smooth solid surface. The expansion creates a lacelike pattern of particle clusters separated by particle-free regions. Both the expansion and the development of the spatial inhomogeneity are dominated by particle inertia and, therefore, are ro...

We present a novel algorithm for accurate, high quality point rendering, which is based on the formulation of splatting using homogeneous coordinates. In contrast to previous methods, this leads to perspective correct splat shapes, avoiding artifacts such as holes caused by the affine approximation of the perspective projection. Further, our algorithm implements the EWA resampling filter, hence...

Point sets from range scanners are noisy and do not contain additional data such as normals, which makes it difficult to create a mesh for rendering. We use the moving least-squares (MLS) approximation to get normals and differential information, and approximate the surface near each point by an MLS surface. From this we obtain a splat of a new octagonal shape which approximates the local curva...

High-temperature erosion is a detrimental phenomenon in industries where particle flow exists, which the search for new materials and mixes to increase lifespan of mechanical components exposed crucial. The present work studied resistance two coatings at 25 °C (RT) 900 sandblast-type rig. were fabricated with cermet-type powders: (C1) commercial Cr3C2-NiCr (C2) mixed laboratory-conditioned powd...
