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,...

Lighting design plays an important role in interactive 3-D training environments; it influences scene perception, scene understanding, attention, visual search, presence, immersion, and emotional involvement. Although there are several research projects that measured the impact of lighting in 3-D environments, little research focused on the development of new lighting design models to enhance t...

Advances in computer graphics have led to the development of interactive entertainment applications with complex 3D graphical environments. Lighting is becoming increasingly important in such applications not only because of its role in illumination, but also because of its utility in directing the viewer’s gaze to important areas and evoking moods. However, lighting design is a complex process...

Lighting design is an important element of scene composition. Designers use lighting to influence viewers’ perception by evoking moods, directing their gaze to important areas, and conveying dramatic tension. Lighting is a very time consuming task; designers typically spend hours manipulating lights’ colors, positions, and angles to create a lighting design that accommodates dramatic action and...

When designing interior lighting effects, it is desirable to compare a variety of lighting designs involving different lighting devices and directions of light. It is, however, time-consuming to generate images with many different lighting parameters, taking interreflection into account, because all luminances must be calculated and recalculated. This makes it difficult to design lighting effec...

This thesis develops a novel technique to enable interactive rendering during lighting design of feature film-quality computer graphics specified in the industry standard RenderMan Interface. This technique is designed to maximize the fidelity of the preview to the results of final-frame rendering, while achieving interactive performance. The technique presented achieves interactive performance...

Lighting design is an essential element of visual storytelling. In cinematic theory, lighting design plays an important role in illumination, directing viewer’s gaze to important locations, and portraying visual tension. However, lighting design is a complex process, and is especially problematic for interactive entertainment systems, since important design parameters such as spatial configurat...

Due to the simplicity and efficiency of panoramic image representation, it has been successfully applied to Internet applications to provide an immersive illusion within a real or synthetic environment. However, once a scene has been captured as image, the lighting condition can no longer be adjustable. As the illumination adjustment is one key capability in computer graphics, we describe in th...

Interactive visualization of complex, real-world light sources has so far not been feasible. In this paper, we present an hardware accelerated direct lighting algorithm based on a recent high quality light source acquisition technique. By introducing an approximate reconstruction of the exact model, a multi-pass rendering approach, and a compact data representation, we are able to achieve inter...
