NON-PHOTOREALISTIC RENDERING OF ALGORITHMICALLY GENERATED TREES

This paper presents hybrid rendering that combines the use of photorealistic and non-photorealistic rendering styles in the same image. This allows to extend the set of expression dimensions available in a visualization environment. To provide general applicability, this use of hybrid rendering styles is controlled by an XML-based scene description. We discuss the according schema definition an...

This paper describes the design of a 3D rendering meta system which wraps the functionality of 3D rendering packages into a uniform, object-oriented framework. The homogeneous interface of the 3D rendering meta system serves as an easy-to-learn application programming interface to 3D rendering packages and allows us to exchange rendering packages without the need to recode an application. Our a...

Modeling and rendering of trees has recently received a lot of attention. Models have been developed that allow photorealistic rendering of trees at interactive frame rates. However, little attention has been devoted to expressive rendering of these models. In this work we present a multiresolution model designed specifically to speed up painterly rendering of trees. Our method proposes a novel...

ParaView is a popular open-source general-purpose scientific visualization application. One of the many visualization tools available within ParaView is the volume rendering of unstructured meshes. Volume rendering is a technique that renders a mesh as a translucent solid, thereby allowing the user to see every point in three-dimensional space simultaneously. Because volume rendering is computa...

We present the concept of volumetric depth-peeling. The proposed method is conceived to render interior and exterior iso-surfaces for a fixed iso-value and to blend them without the need to render the volume multiple times. The main advantage of our method over pre-integrated volume rendering is the ability to extract arbitrarily many iso-layers for the given iso-value. Up to now, pre-integrate...

Non-photorealistic rendering techniques work on image features and often manipulate a set of characteristics such as edges and texture to achieve a desired depiction of the scene. Most computational photography methods decompose an image using edge preserving filters and work on the resulting base and detail layers independently to achieve desired visual effects. We propose a new approach for c...

Photorealism is one of the most quoted aspects of nowadays games. However, realistic game graphics is not the only style desirable. This paper surveys the many graphical styles used in past and current games, analyzes graphical aspects of computer games and discuss the use of realism with respect to game graphics. We show several examples and make references to current research, encouraging gam...
