Real-Time Shadows

چکیده
Shadows are important elements in creating a realistic image and in providing the user with visual cues about object placement. A review of many different shadow algorithms is found in the survey published by Woo et al. [23] and in Watt and Watt’s book [21]. Here we will present the most important real-time algorithms for dynamic shadows. The first section handles the special case of shadows cast on planar surfaces, and the second section covers more general shadow algorithms, i.e., casting shadows onto arbitrary surfaces.

A Real-Time Soft Shadow Volume Algorithm
Rendering of shadows is a very important ingredient in three-dimensional graphics since they increase the level of realism and provide cues to spatial relationships. Area or volumetric light sources give rise to so called soft shadows, i.e., there is a smooth transition from no shadow to full shadow. For hard shadows, which are generated by point light sources, the transition is abrupt. Since a...
متن کاملGeometry of Real Time Shadows Geometry of Real Time Shadows
Shadows provide important visual hints about the spatial relationship between objects. Shadow volumes are one way to generate sophisticated shadows for use in real time environments. This paper focuses on the geometric aspects which are involved in the creation of the shadow volume. Speed up techniques like shaders and dual space approaches for silhouette determination are discussed. Finally th...
متن کاملEfficient Generation of Soft Shadow Textures
Soft shadows give important cues of realism to 3D scenes. Existing methods can produce hard shadows in real time and soft shadows in minutes to hours per frame. Here a technique for producing accurate soft shadows quickly in software is presented, allowing soft shadow texture maps to be computed for simple scenes on commodity hardware in real time.
متن کاملAutomatic generation of consistent shadows for augmented reality
In the context of mixed reality, it is difficult to simulate shadow interaction between real and virtual objects when only an approximate geometry of the real scene and the light source is known. In this paper, we present a realtime rendering solution to simulate colour-consistent virtual shadows in a real scene. The rendering consists of a three-step mechanism: shadow detection, shadow protect...
متن کاملReal-time Soft Shadow Mapping using the DDOC
Soft shadows provide important information to viewers about spatial relationships between objects. Generating accurate soft shadows in real time has been a focus of research in computer graphics. Shadow mapping is a standard way of generating hard shadows in real time and several methods including Smoothies [Chan and Durand 2003] and penumbra maps [Wyman and Hansen 2003] extend the standard sha...
