Image synthesis of natural phenomena is one of the fundamental research areas in volume graphics. Since the pursuit of photoreality requires physically-based computation at the cost of interactivity, much more attention ...

Earlier proposed antialiasing techniques for voxelization of geometric objects in some cases do not result in completely alias-free data and image renditions. This is often the case for some implicit solids and CSG trees. ...

One of the most severe problems for ray casting architectures is the waste of computation cycles and I/O bandwidth, due to redundant sampling of empty space. While several techniques exist for software implementations to ...

This paper describes vlib, a generic application programming interface for volume graphics which supports many of the significant developments in the field to date. We present an overview of the interface and describe how ...

The proper usage and creation of transfer functions for time-varying data sets is an often ignored problem in volume visualization. Although methods and guidelines exist for time-invariant data, little formal study for the ...

In this paper, a new technique for volumetric CSG is presented. The technique requires the input volumes to correspond to solids which fulfill a voxelization suitability criterion. Assume the CSG operation is union. The ...

We present a method of accelerated perspective volume rendering using cell projection, triangle fans, and a data hierarchy. The hierarchy allows mixed resolution rendering, greatly increasing speed. We utilize triangle ...

We propose a voxel-based terrain rendering method which incorporates a novel keyframe-free image-based rendering algorithm and a new heuristic ray coherence raycasting algorithm. The current image is generated by warping ...

In this paper we describe an efficient approach to add shadows to volumetric scenes. The light emitted by the lightsource is properly attenuated by the intervening volumetric structures before it is reflected towards the ...

Refraction is an important graphics feature for synthesizing photorealistic images. This paper presents a study on refraction rendering in volume graphics using discrete ray tracing. We describe four basic approaches for ...
