Imperfection for realistic image synthesis
The precision of image synthesis techniques for rendering naturalistic scenes often works contrary to the realism of the everyday world. Pristine, crystalline, uniform and perfect may describe the most idealized computer images: the surfaces are smooth, neat and crisp in appearance. Efforts to produce realism have recently focused on light and the interaction of light with surfaces. The radiosi...
متن کاملComputational Methods for Realistic Image Synthesis
Computational Methods for Realistic Image Synthesis Min-Zhi Shao Supervised by Dr. Norman I. Badler In this thesis, we investigate the computational methods for both diffuse and general reflections in realistic image synthesis and propose two new approaches: the overrelaxation solution and the Bernstein polynomial solution. One of the major concerns with the radiosity method is its expensive co...
متن کاملEnabling Increased Complexity for Realistic Image Synthesis
This dissertation discusses work that enables the realistic image synthesis of very complex scenes. Some of the work herein describes approaches for modeling more complicated scenes, while other portions describe algorithms for accelerating the rendering of complex scenes. First we propose a simple method for modeling and rendering refractive objects that are nested within each other. The techn...
متن کاملA Spectral Database for Realistic Image Synthesis
A database for storing and searching spectral curves is presented. The database gives the user of a synthetic imaging system a means to select spectral reflectance, emittance, transmittance, and absorptance curves for use in the realistic image synthesis process. This provides an alternative to the usual RGB and HSV interfaces that are typically used for image color selection and specification....
متن کاملHybrid scheduling for realistic image synthesis
Rendering a single high quality image may take several hours, or even days. The complexity of both the model and the lighting simulation may require excessive computer resources. In order to reduce the total rendering time and to accommodate large and complex models that exceed the size of a single processor system, a parallel renderer may provide a viable alternative to sequential computing. I...
