While modern rendering systems are efficient for modeling complex light paths in complex environments, the rendering of refractive caustics still takes a long time. Caustics are light patterns that occur when light is refracted and reflected from ...

Compositing virtual objects into real background images requires one to carefully match the scene’s camera parameters, surface geometry, textures, and lighting to obtain plausible renderings. Recent learning approaches have shown many scene properties ...

Esports athletes often reduce visual quality to improve latency and frame rate, and increase their in-game performance. Little research has examined the effects of this visuo-spatial tradeoff on performance, but we could find no work studying how ...

This talk presents significant rendering-related CPU and GPU optimizations concerning shadows in Cyberpunk 2077. Given the scale of the game and the variety of platforms that it has to support, different solutions had to be implemented and coupled in ...

We present the design and prototype of ShadowSparrow, an ambient display utilizing lights & shadows. The concept uses illustrative bird images and other relevant visuals (e.g., dishwasher and e-mail icons) cast on the surroundings for ambient ...

This paper explores the concept of using human shadows as an ambient information display. As shadows are an integral part of the physical world, consisting of non-illuminated and dynamic shapes, they provide a potential basis for the design of ...

The amount of status and notification information available to people is increasing beyond the capacity of the current primary delivery channel of smartphones. Ambient displays, e.g. embedded in the home or work environment present an alternative ...

Tracking of moving objects in video sequences is an important research problem because of its many industrial, biomedical, and security applications. Significant progress has been made on this topic in the last few decades. However, the ability to track ...

In this study, a novel multi‐layer fused convolution neural network (MLF‐CNN) is proposed for detecting pedestrians under adverse illumination conditions. Currently, most existing pedestrian detectors are very likely to be stuck under adverse illumination ...

In immersive projection systems (IPS), the presence of the user's real body limits the possibility to elicit a virtual body ownership illusion. But, is it still possible to embody someone else in an IPS even though the users are aware of their real body?...

Compositing transparent surfaces rendered in an arbitrary order requires techniques for order-independent transparency. Each surface color needs to be multiplied by the appropriate transmittance to the eye to incorporate occlusion. Building upon moment ...

In this paper, we propose a ratio estimator of the direct-illumination equation that allows us to combine analytic illumination techniques with stochastic raytraced shadows while maintaining correctness. Our main contribution is to show that the ...

Light mapping is an important optimization technique, in which the lighting of a scene is precomputed into a texture during a stage known as light baking. However, the primary drawback of this technique is that lights and objects must be static. Our ...

Moment shadow maps enable direct filtering to accomplish proper antialiasing of dynamic hard shadows. For each texel, the moment shadow map stores four powers of the depth in either 64 or 128 bits. After filtering, this information enables a heuristic ...

Local cubemaps (LC) were introduced for the first time more than ten years ago for rendering reflections [Bjorke 2004]. Nevertheless it is only in recent years that major game engines have incorporated this technique. In this paper we introduce a ...

Lighting large outdoor scenes continues to present a challenge for realtime rendering. While techniques such as Parallel Split Shadow Maps [Zhang 2006] work well for a subset of the view frustum they fail to account for all shadowing in an outdoor ...

Shadow theatre is a genre of performance art in which the actors are only visible as shadows projected on the screen. The goal of this study is to generate animated characters, the shadows of which match a sequence of target silhouettes. This poses ...

We present a real-time system that renders antialiased hard shadows using irregular z-buffers (IZBs). For subpixel accuracy, we use 32 samples per pixel at roughly twice the cost of a single sample. Our system remains interactive on a variety of game ...

We describe a method for detecting physical inconsistencies in lighting from the shading and shadows in an image. This method imposes a multitude of shading- and shadow-based constraints on the projected location of a distant point light source. The ...

We present the surface area traversal order SATO metric to accelerate shadow ray traversal. Our formulation uses the surface area of each child node to compute the TO. In this metric, we give a traversal priority to the child node with the larger ...
