Hierarchical Skeletal Modelling System

A hierarchical skeletal modelling system is an improvement to the basic modelling skeleton in which there is a clear hierarchy between the bones. This is accomplished by means of a second object space, which each bone shares. In this space, each bone?s axis is positioned relative to that of its parent bone?s axis. For example, the forearm bone is a child of the upper arm bone, which is a child of the shoulder bone and so on.

The advantage is that if you move the parent bone, the children will move as well, trying to stay in position relative to the parent. For example, rotate the torso, and the effect will filter through to the arm bones, making the arms swivel with the same motion, without being explicitly told to.

Rapid interactive scene modelling from video
A new modelling system, VideoTrace; the result of a collaboration between The Australian Centre for Visual Technologies at the University of Adelaide, and The Oxford Brookes Computer Vision Group, is capable of taking the output of any handheld digital camcorder, and turn it into a 3D model.

Large Image Display: Prosthetic Jaw Hinging
One of the most important aspects when working with any skeletal system, is the joint where bones connect. If you don't get this area right, then bone will grind against prosthesis, and the bone is likely to take critical damage first. You inflame a joint, that did not have a problem in the first place, and spread further complications throughout the body.

Modelling Digital Dinosaurs

Not a platform or modelling software specific book, Modelling Digital Dinosaurs is Ken?s first book, and it takes you through the basics of creating 3D representations of something which has fascinated and captivated for centuries ? dinosaurs. The book does this in a patient, kind, step by step manner, demonstrating techniques which really aid the beginning to intermediate modeller. Contains a free copy of Amapi version 1.5 on the CD in case the reader does not have a 3D modeller.

Simplicity Versus Realism in Medical VR
We are so caught up in our desire for ever greater realism and ever greater accuracy when using VR and modelling tools to render the human body for diagnosis in whole or in part, that we often forget the benefits of simplicity. HemoVis, a medical VR tool for assessing weak points in the coronary system, achieves far better results with a 2D system than 3D with all the bells and whistles used more commonly in diagnosis.

The Status of Realistic modelling on Home PCs: Technological Progress 2008 - Nvidea 8800
Recreating utterly realistic, and believable humanoid avatars has been a goal of graphic design and modelling since time immemorial. We take a look at the limit of the real-time capabilities of the Nvidia 8800, as to progression made, to date.
