Handling many light sources in real-time is still one of the big challenges in real-time graphics [Sousa and Geffroy 2016; Garawany 2016]. Even the most recent approaches like practical clustered shading still have various problem cases with low ...

We introduce a new data structure and algorithms that employ it to compute real-time global illumination from static environments. Light field probes encode a scene's full light field and internal visibility. They extend current radiance and irradiance ...

Many previous efforts have been focused on generating optimal coordinates for cage deformation; cage generation for 3D models has been relatively understudied. We introduce an efficient complete pipeline to generate high quality cages for 3D models with ...

Continuous collision detection (CCD) is a process to interpolate the trajectory of polygons and detect collisions between successive time steps. However, primitive-level CCD is a very time-consuming process especially for a large number of moving ...

Modeling cloth with fiber-level geometry can produce highly realistic details. However, rendering fiber-level cloth models not only has a high memory cost but it also has a high computation cost even for offline rendering applications. In this paper we ...

Grass plays an important role in most natural environments. Most interactive applications use image-based techniques to approximate fields of grass due to the high geometrical complexity, leading to visual artifacts. In this paper, we propose a grass-...

Renderers apply alpha testing to mask out complex silhouettes using alpha textures on simple proxy geometry. While widely used, alpha testing has a long-standing problem that is underreported in the literature, but observable in commercial games: ...

Accurately drawing 3D objects is difficult for untrained individuals, as it requires an understanding of perspective and its effects on geometry and proportions. Step-by-step tutorials break the complex task of sketching an entire object down into easy-...

Capturing urban scenes using photogrammetric methods has become an interesting alternative to laser scanning in the past years. For the reconstruction of CAD-ready 3D models, two main types of interactive approaches have become prevalent: One uses the ...

Two-dimensional heightfields are the most common data structure used for storing and rendering of terrain in offline rendering and especially real-time computer graphics. By its very nature, a heightfield cannot store terrain structures with multiple ...

We propose the first working GPU algorithm for the 2D Delaunay refinement problem. Our algorithm adds Steiner points to an input planar straight line graph (PSLG) to generate a constrained Delaunay mesh with triangles having no angle smaller than an ...

Particle-based methods like Smoothed Particle Hydrodynamics (SPH) are increasingly adopted for large scale fluid simulation in interactive computer graphics. However, surface rendering for such dynamic particle sets is challenging: current methods ...

We explore the problem of decoupling color information from geometry in large scenes of voxelized surfaces and of compressing the array of colors without introducing disturbing artifacts. First, we present a novel method for connecting each node in a ...

We present a new method, Motion Picture Texture Compression (MPTC), to compress a series of video frames into a compressed video-texture format, such that the decoded output can be rendered using commodity texture mapping hardware. Our approach reduces ...

For generalized augmented reality to be feasible, the augmenting elements must be visible in varied environments and under rapidly changing, high dynamic range lighting, from bright sunlight to deep shadows. We present a high dynamic range, optical see-...

Kd-tree is a fundamental data structure with extensive applications in computer graphics. The performance of many interactive applications such as real-time ray tracing hinges on the construction and traversal efficiency of kd-trees. In recent years, ...

ANEEME is a system for automatic skeletal rigging of 3D scanned humanoid objects such as toys, figurines, sculptures and even humans. Unlike other automatic skeletal rigging techniques, ANEEME does not require humanoid objects to be in a specific pose, (...

A school of fish exhibit a variety of distinctive maneuvers to escape from predators. Although these escape maneuvers have long been observed and studied in the fields of biology and ecology, they have not been sufficiently modeled in computer graphics. ...

We present a method for the real-time procedural generation of a growing plant based on biological rules and physical assumptions, using corn as our model organism. Circular contours and segments of spirals are used to model the plant modules, i.e. leaf ...

In order to support the realistic virtual reality environment, it is necessary to reproduce virtual space and virtual acoustic space. The multi-channel audio system or a 3D sound technology using head related transfer function (HRTF) is used to ...

To create brush-stroke style animation with temporal coherence, the artist needs to refer the previous frame carefully for drawing. Moreover, brush-stroke lighting style is challenging to animate coherently because it dynamically changes and contains ...

Physically walking in a virtual world has been repeatedly demonstrated to be superior to navigation with game controllers and the like. The problem is that virtual worlds are often much larger than the available physical space. Redirected walking, a ...
