Light Space Perspective Shadow Maps
In this paper, we present a new shadow mapping technique that improves upon the quality of perspective and uniform shadow maps. Our technique uses a perspective transform specified in light space which allows treating all lights as directional lights and does not change the direction of the light sources. This gives all the benefits of the perspective mapping but avoids the problems inherent in...
متن کاملThe Shadow of Light: Further Experimental Evidences
We report the results of a double-slit-like experiment in the infrared range, which confirm those of a previous one by evidencing an anomalous behaviour of photon systems under particular (energy and space) constraints. These outcomes (independently confirmed by crossing photon beam experiments in both the optical and the microwave range) apparently rule out the Copenhagen interpretation of the...
متن کاملShadow Elimination and Blinding Light Suppression for Interactive Projected Displays
A major problem with interactive displays based on front projection is that users cast undesirable shadows on the display surface. This paper demonstrates that shadows can be muted by redundantly illuminating the display surface using multiple projectors, all mounted at different locations. However, this technique alone does not eliminate shadows: Multiple projectors create multiple dark region...
متن کاملCaching in Ubiquitous Computing Environments: Light and Shadow
of the CA is described as follows. 1. Router retrieves a new task from the task queue. If there is no task in the task queue, then ends. 2. Router generates a PE chain which is used to process a task. Set the PEs in the PE chain as busy, which means these PE can not do any other task until they are released. 3. Router sends the PE chain information and task to PE1. 4. PE1 finishes its work and ...
متن کاملShadow Mapping for Hemispherical and Omnidirectional Light Sources
In this paper we present a shadow mapping technique for hemispherical and omnidirectional light sources using dual-paraboloid mapping. In contrast to the traditional perspective projection this parameterization has the benefit that only a minimal number of rendering passes is needed during generation of the shadow maps, making the method suitable for dynamic environments and real time applicati...
