Nvidia Corporation is an American worldwide technology company based in Santa Clara, California. Nvidia manufactures graphics processing units , as well as system-on-a-chip units for the mobile computing market. Nvidia's primary GPU product line, labeled "GeForce", is in direct competition with AMD's "Radeon" products. Nvidia also joined the gaming industry with its handheld Shield Portable and Shield Tablet, as well as the tablet market with the Tegra Note 7.In addition to GPU manufacturing, Nvidia provides parallel processing capabilities to researchers and scientists that allow them to efficiently run high-performance applications. They are deployed in supercomputing sites around the world. More recently, Nvidia has moved into the mobile computing market, where it produces Tegra mobile processors for smartphones and tablets, as well as vehicle navigation and entertainment systems. In addition to Advanced Micro Devices, its competitors include Intel and Qualcomm. Wikipedia.

We address the problem of Multi-Phase (or Many-Phase) Fluid simulations. We propose to use the regional level set (RLS) that can handle a large number of regions and materials, and hence, is appropriate for simulations of many immiscible materials. Towards this goal, we improve the interpolation of the RLS, and develop the regional level set graph (RLSG), which registers connected components and their contacts, and tracks their properties such as region volumes, film life times, and film material types, as regions evolve, merge, split, or are squeezed into films. Using RLSG's tracking feature, we generate particles from tiny regions or rupturing films. © 2010 ACM. Source

A number of methods for constructing bounding volume hierarchies and point-based octrees on the GPU are based on the idea of ordering primitives along a space-filling curve. A major shortcoming with these methods is that they construct levels of the tree sequentially, which limits the amount of parallelism that they can achieve. We present a novel approach that improves scalability by constructing the entire tree in parallel. Our main contribution is an in-place algorithm for constructing binary radix trees, which we use as a building block for other types of trees. © The Eurographics Association 2012. Source

A system, method, and computer program product are provided fir shading using a dynamic object-space grid. An object defined by triangle primitives in a three-dimensional (3D) space that is specific to the object is received and an object-space shading grid is defined for a first triangle primitive of the triangle primitives based on coordinates of the first triangle primitive in the 3D space. A shader program is executed by a processing pipeline to compute a shaded value at a point on the object-space shading grid for the first triangle primitive.

A system, method, and computer program product are provided for performing object-space shading. A primitive defined by vertices in three-dimensional (3D) space that is specific to an object defined by at least the primitive is received and a shading sample rate is computed for the primitive based on a screen-space derivative of coordinates of a pixel fragment transformed into the 3D space. A shader program is executed by a processing pipeline to compute shaded attributes for the primitive according to the computed shading sample rate.

A true random number generator, a method of generating a true random number and a system incorporating the generator or the method. In one embodiment, the generator includes: (1) a ring oscillator including inverting gates having power inputs and (2) a time-varying power supply coupled to the power inputs to provide power thereto and including power perturbation circuitry operable to perturb the power provided to at least one of the power inputs.
