Hierarchical Representation of Surfaces Using 3D Wireframes

Representation of Adsorption Data for the Case of Energetically Heterogeneous Solid Surfaces Using Artificial Neural Network

Pose Estimation using a Hierarchical 3D Representation of Contours and Surfaces

We present a system for detecting the pose of rigid objects using texture and contour information. From a stereo image view of a scene, a sparse hierarchical scene representation is reconstructed using an early cognitive vision system. We define an object model in terms of a simple context descriptor of the contour and texture features to provide a sparse, yet descriptive object representation....

An Independent Declarative 3d Audio Format on the Basis of Xml

This paper describes the development of an XML-based format called Audio3D for the declarative description of acoustic environments and sound sources for 3D auditory displays by an audio designer without the need of programming efforts. The format is platform and API independent and suitable for realtime and offline sound rendering. It can be used together with other XML-formats for 3D graphics...

Neural Network Based Reconstruction of a 3D Object from a 2D Wireframe

We propose a new approach for constructing a 3D representation from a 2D wireframe drawing. A drawing is simply a parallel projection of a 3D object onto a 2D surface; humans are able to recreate mental 3D models from 2D representations very easily, yet the process is very difficult to emulate computationally. We hypothesize that our ability to perform this construction relies on the angles in ...

BOXTREE: A Hierarchical Representation for Surfaces in 3D

We introduce the boxtree, a versatile data structure for representing triangulated or meshed surfaces in 3D. A boxtree is a hierarchical structure of nested boxes that supports e cient ray tracing and collision detection. It is simple and robust, and requires minimal space. In situations where storage is at a premium, boxtrees are e ective alternatives to octrees and BSP trees. They are also mo...
