3D Computer Graphics

1998
As you have probably realized, virtual reality (VR) is basically about three-dimensional (3D) computer graphics, and in this chapter we are going to explore some of the techniques used to produce coloured views of virtual environments (VEs).

Exploring 3D computer graphics in cockpit avionics

IEEE Computer Graphics and Applications, 1993
A system that uses 3-D computer graphics to integrate and visualize flight information and to encode navigational information of the objects of a 3-D scene is described. The computer-generated views of geographic features, weather information, and air traffic used in the system are discussed.

Stream 3D: Computer graphics program for streamline visualization

Advances in Engineering Software (1978), 1989
Abstract The present streamline visualization program is based on the technique of mapping the physical domain to a rectangular block. The streamline computation proceeds by integrating the mapped velocity vectors in isoparametric cells and plotting the coordinates of the streamlines thus obtained.

What can Computer Graphics expect from 3D Computer Vision?

Computer Graphics Forum, 2007
Abstract Computer Vision is a discipline whose ultimate goal is to interpret optical images of real scenes. It is well understood that such a problem is cursed by ambiguity of interpretation and uncertainty of evidence. Despite imperfectness of results due to the scenes never following our prior models exactly, Computer Vision has achieved a ...

3D graphical user interface for computer-assisted surgery

International Congress Series, 2003
Abstract We have examined what contributions the combination of augmented reality (AR) and hand input can make to a 3D graphical user interface (GUI) for computer-assisted surgery. We have developed an early prototype of a GUI that can be operated in augmented space. The user interacts with the GUI by pointing with his hands. Future work will include

Implementation Of True 3D Cursors In Computer Graphics

SPIE Proceedings, 1988
The advances in stereoscopic image display techniques have shown an increased need for real-time interaction with the three-dimensional image. We have developed a prototype real-time stereoscopic cursor to investigate this interaction. The results have pointed out areas where hardware speeds are a limiting factor, as well as areas where various ...

Reflectance Analysis for 3D Computer Graphics Model Generation

Graphical Models and Image Processing, 1996
Abstract For synthesizing realistic images of a real three dimensional object, reflectance properties of the object surface, as well as the object shape, need to be measured. This paper describes one approach to create a three dimensional object model with physically correct reflectance properties by observing a real object.

3D Object tracking using computer graphics and edge

2011 IEEE International Conference on Robotics and Biomimetics, 2011
We have proposed a 3D object tracking framework with a Coarse-to-Fine combination strategy for robot vision applications. In the coarse step, compared with those edge-based only methods, the convergence range of initial camera pose estimation has been enlarged in our system by a template-based matching between a series of template images rendered from ...

3D model-based video coding: Computer vision meets computer graphics

1995
This paper describes the model-based video coding scheme which combines computer vision and computer graphics techniques. Human face modeling system is used as an example. In this system, a generic 3D face model is used for both facial motion analysis and expression synthesis.
