Deep framebuffer relighting engines are often used to speed up lighting design in geometricallycomplex procedurally-shaded environments where they provide interactive feedback on changes to the direct illumination. This paper presents an extension to these algorithms by providing real-time feedback for one-bounce indirect illumination. This is achieved by relighting a set of cached gather sampl...

Panoramic images can be used as an image-based method for navigating in a real environment. Recent publications have shown that it is possible to augment photographs with correct lighting. We combine these two approaches to an interactive tool with real-time modifications of the real scene maintaining consistent lighting. The possible changes are: Insertion of virtual objects, new light sources...

Rapidly simulating global illumination, including diffuse and glossy light transport is a very difficult problem. Finite element or radiosity approaches can achieve interactive simulations for some classes of diffuse-only scenes, but more general methods are currently too slow and too noisy for interactive use. We present a new method which seamlessly integrates particle tracing (for nondiffuse...

Current computing devices span a large and varied range of computational power. Interactive high-fidelity graphics is still unachievable on many of the devices widely available to the public, such as desktops and laptops without high-end dedicated graphics cards, tablets and mobile phones. In this paper we present a scalable solution for interactive high-fidelity graphics with global illuminati...

Triple product integrals evaluate the shading at a point by factoring the reflection equation into incident illumination, visibility, and BRDF. By densely sampling the space of incident directions, this approach is capable of highly accurate rendering scenes lit by high-frequency environment lighting, containing complex materials and featuring intricate shadows. Efficient evaluation of triple p...

Interactive rendering of global illumination effects is a challenging problem. While precomputed radiance transfer (PRT) is able to render such effects in real time the geometry is generally assumed static. This work proposes to replace the precomputed lighting response used in PRT by precomputed depth. Precomputing depth has the same cost as precomputing visibility, but allows visibility tests...

Urban space can be the most successful public arena in this century if employ the potentialsfor collective cooperation in creative ways in order to provide further services. The theory of creative city tries tostrengthen the qualities which enhance the image of a city for the citizens and create a dynamic city in terms of cultureand intercultural learning. Therefore, the existence of generator,...

It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the ...
