We present a new fractal based method of generating realistic models of natural landscapes. In this paper, we describe a three-steps method that produces a terrain mesh using ridge lines and rivers drainage network. As opposed to previous methods that ...

We propose a non-redundant DAG hierarchy for view-dependent multiresolution mesh for client-server based online browsing of triangle mesh models. The multiresolution hierarchy and the selectively refined mesh for rendering are two relatively independent ...

In this paper, we present sketchy-ar-us, a modified, real-time version of the Loose and Sketchy algorithm used to render graphics in an AR environment. The primary challenge was to modify the original algorithm to produce a NPR effect at interactive ...

The developers and users of real-time graphics, such as games and virtual reality, are demanding ever more realistic computer generated images. Despite the availability of modern graphics hardware, such real-time high fidelity graphics is still not ...

We propose a new global light simulation method for diffuse (or moderately glossy) scenes comprising highly tesselated models with simple topology (e.g., scanned meshes). By using the topological coherence of the surface, we show how to extend a classic ...

Planetariums and smaller personal domes can provide an immersive environment for science education, virtual reality, and entertainment [Shaw 1998]. Digital projection into domes, called "full dome projection" in the industry, can be a technically ...

There is an ever increasing demand for higher levels of visual detail in graphical applications, particularly in computer games and applications employing visualisation. Triangle strips have been commonly used to optimise the rendering of large ...

This paper concerns real-time rendering of thin semi-transparent objects. An object in this category could be a piece of cloth, eg. a curtain. Semi-transparent objects are visualized most correctly using volume rendering techniques. In general such ...

Translucent photon mapping is a technique developed for the realistic rendering of translucent materials such as milk, skin, and fog. In the physical world, however, no material is perfectly translucent at a constant density. By using a 3D density map ...

Due to renewed interest in security, iris images have become a popular biometric alternative to fingerprints for human identification. However, there exist very few databases on which researchers can test iris recognition technology. We present a novel ...

This paper presents a non-conservative occlusion culling technique for dynamic scenes with animated or user-manipulated objects. We use a multi-pass algorithm, which decides the visibility based on low level of detail representations of the geometric ...

Interactive exploration of huge tetrahedral meshes is required by many applications but the limitations of the current hardware do not allow for the full dataset to be rendered at interactive frame rates. Multi resolution representations are an ...
