Accurate Specular Reflections in Real-Time
Specular reflections provide many important visual cues in our daily environment. They inform us of the shape of objects, of the material they are made of, of their relative positions, etc. Specular reflections on curved objects are usually approximated using environment maps. In this paper, we present a new algorithm for real-time computation of specular reflections on curved objects, based on...
متن کاملAccurate Interactive Specular Reflections on Curved Objects
We present a new method to compute interactive reflections on curved objects. The approach creates virtual reflected objects which are blended into the scene. We use a property of the reflection geometry which allows us to efficiently and accurately find the point of reflection for every reflected vertex, using only reflector geometry and normal information. This reflector information is stored...
متن کاملReal-Time Recursive Specular Reflections on Planar and Curved Surfaces using Graphics Hardware
Real-time rendering of recursive reflections have previously been done using different techniques. However, a fast unified approach for capturing recursive reflections on both planar and curved surfaces, as well as glossy reflections and interreflections between such primitives, have not been described. This paper describes a framework for efficient simulation of recursive specular reflections ...
متن کاملDetecting Specular Reflections Using Lambertian Constraints
Specularities-bright image regions formed by specular reflection-are likely to be mistaken for genuine surface markings by processes that perform photometric analysis, derive motion fields from optical flow or est imate depth from binocular stereo. In addition th ey can be used to infer surface geometry. This paper describes a scheme for detecting specularities based on a characterisation of La...
متن کاملSpecular reflections and the perception of shape.
Many materials, including leaves, water, plastic, and chrome exhibit specular reflections. It seems reasonable that the visual system can somehow exploit specular reflections to recover three-dimensional (3D) shape. Previous studies (e.g., J. T. Todd & E. Mingolla, 1983; J. F. Norman, J. T. Todd, & G. A. Orban, 2004) have shown that specular reflections aid shape estimation, but the relevant im...
