We propose to use tetrahedrons as primitives for volume rendering and a pipeline to rasterize them. Our work relies on the recently introduced mesh shaders to encode each tetrahedron such that the rasterizer computes the depths of the front and back ...

Distributed hybrid rendering (DHR) is a real-time rendering approach that incorporates cloud-based ray tracing with locally rasterized graphics for interactive thin client metaverse and game applications. With cloud assistance, DHR can generate ...

In this paper, we introduce a novel method for particle-based fluid surface reconstruction that incorporates mesh shaders for the first time. This approach eliminates the need to store triangle meshes in a GPU's global memory, resulting in a significant ...

The lens flare phenomenon is often an undesired artifact of the imaging process; however, it has become an important artistic tool in photography and cinematography as well as a highly impactful component for increasing the level of realism for ...

The availability of the Global Positioning System (GPS) trajectory data is increasing along with the availability of different GPS receivers and with the increasing use of various mobility services. GPS trajectory is an important data source which ...

Recently, massively-parallel computing libraries and devices are much widely used, in addition to the traditional 3D graphics systems. In this paper, we present a full 3D fixed-function graphics pipeline, based on the OpenCL, which is one of the ...

In this paper, we present a study on the available open-source software (OSS) for large-scale data visualization on the SPARC64fx based HPC systems, such as the K computer and also the Fujitsu PRIMEHPC FX family of supercomputers (FX10 and FX100), which ...

In computer vision, convolutional neural networks CNNs achieve unprecedented performance for inverse problems where RGB pixel appearance is mapped to attributes such as positions, normals or reflectance. In computer graphics, screen space shading has ...

Hair is typically modeled and rendered using either explicitly defined hair strand geometry or a volume texture of hair densities. Taken each on their own, these two hair representations have difficulties in the case of animal fur as it consists of very ...

3D geological underground models are often presented by vector data, such as triangulated networks representing boundaries of geological bodies and geological structures. Since models are to be used for numerical simulations based on the finite ...

We present a new method for real-time rendering of multiple recursions of reflections and refractions. The method uses the strengths of real-time ray tracing for objects close to the camera, by storing them in a per-frame constructed bounding volume ...

We present an exact general remeshing scheme to compute analytic integrals of polynomial functions over the intersections between convex polyhedral cells of old and new meshes. In physics applications this allows one to ensure global mass, momentum, and ...

With the expansion of complex geographic calculations and the increase of spatial data types involved in the spatial analysis of large areas, the need becomes urgent for fast rasterization of massive multi-source geographic vector data. A parallel ...

Graphics processing units supporting tessellation of curved surfaces with displacement mapping exist today. Still, to our knowledge, culling only occurs after tessellation, that is, after the base primitives have been tessellated into triangles. We ...

We present a novel framework for real-time multi-perspective rendering. While most existing approaches are based on ray-tracing, we present an alternative approach by emulating multi-perspective rasterization on the classical perspective graphics ...
