With the push towards physically based rendering, stochastic sampling of shading, e.g. using path tracing, is becoming increasingly important in real-time rendering. To achieve high performance, only low sample counts are viable, which necessitates the ...

We present a technique to importance sample large collections of lights (including mesh lights as collections of small emitters) in the context of Monte-Carlo path tracing. A bounding volume hierarchy over all emitters is traversed at each shading point ...

We present a new algorithm for image-based simplification of complex scenes for virtual reality (VR). The algorithm transforms geometrically-detailed environments into a layered quad tile representation that is optimized for a specified viewing region ...

In this paper, a new method is introduced to calculate the volumetric divergence (VD) metric, which is defined as the volume between the extracted isosurface mesh and the isosurface given by trilinear interpolation. This metric can be used to evaluate ...

Due to its flexibility, compute mode is becoming more and more attractive as a way to implement many of the algorithms part of a state-of-the-art rendering pipeline. A key problem commonly encountered in graphics applications is streaming vertex and ...

In this paper, we question the premise that graphics hardware uses a post-transform cache to avoid redundant vertex shader invocations. A large body of existing work on optimizing indexed triangle sets for rendering speed is based upon this widely-...

Generating well-distributed Poisson-disk samples with a blue noise power spectrum on 3D meshes is required by a wide range of applications in computer graphics. We introduce a novel method called Progressive Sample Projection that can generate massive ...

We propose a new by-example noise algorithm that takes as input a small example of a stochastic texture and synthesizes an infinite output with the same appearance. It works on any kind of random-phase inputs as well as on many non-random-phase inputs ...

Procedural noise functions have many applications in computer graphics, ranging from texture synthesis to atmospheric effect simulation or to landscape geometry specification. Noise can either be precomputed and stored into a texture, or evaluated ...

Subdivision surfaces, especially with displacement, are one of the key modeling primitives used in high-quality rendering environments, such as, e.g., movie production. While their use easily maps to rasterization-based frameworks, they pose a ...

We present a new approach to ray tracing swept volumes along trajectories defined by cubic Bézier curves. It performs at two-thirds of the speed of ray-triangle intersection, allowing essentially even treatment of such primitives in ray tracing ...

In the near future, GPUs are expected to have hardware support for real-time ray tracing in order to, e.g., help render complex lighting effects in video games and enable photorealistic augmented reality. One challenge in real-time ray tracing is ...
