چکیده

We present a technique which uses existing OpenGL capabilities to approximate the effect of blurry specular reflections and indirect diffuse illumination. It makes use of environment maps, mipmapping with level of detail control, and possibly texture borders. The method is extremely simple to implement, in some cases requiring just a single additional OpenGL statement.

Product preservation and stable units for reflections into idempotent subvarieties

We give a necessary and sufficient condition for the preservation of finite products by a reflection of a variety of universal algebras into an idempotent subvariety. It is also shown that simple and semi-left-exact reflections into subvarieties of universal algebras are the same. It then follows that a reflection of a variety of universal algebras into an idempotent subvariety has stable units...

Reflected-Scene Impostors for Realistic Reflections at Interactive Rates

We present a technique for rendering reflections on complex reflectors at interactive rates based on approximating the geometry of the reflected scene with impostors. The reflections correctly convey the distance to the reflector surface and provide motion parallax. Two types of impostors are adapted to the reflections framework: billboards and depth maps. Billboards remove most of the problems...

Depth Map Completion by Jointly Exploiting Blurry Color Images and Sparse Depth Maps

We aim at predicting a complete and high-resolution depth map from incomplete, sparse and noisy depth measurements. Existing methods handle this problem either by exploiting various regularizations on the depth maps directly or resorting to learning based methods. When the corresponding color images are available, the correlation between the depth maps and the color images are used to improve t...

Advanced environment mapping in VR applications

In this paper, we propose an approach for rendering diffuse and glossy reflections using environment maps. This approach is geared towards VR applications, where realism and fast rendering is important. We exploit certain mathematical properties of diffuse reflections and certain features of graphics hardware for glossy reflections. This results in a very fast, single-pass rendering algorithm, ...

Light Field Techniques for Reflections and Refractions

Reflections and refractions are important visual effects that have long been considered too costly for interactive applications. Although most contemporary graphics hardware supports reflections off curved surfaces in the form of environment maps, refractions in thick, solid objects cannot be handled with this approach, and the simplifying assumptions of environment maps also produce visible ar...
