LOD Geometry System

A LOD Geometry system is an engine which is tasked with a dynamic reduction in the number of polygons in a 3D model, based on distance from the viewpoint, in much the same way as a physics engine is applied to a potential render frame.

A basic problem in computer vision is to understand the structure of a physical sceene from just one or two camera?s perspective. This book attempts to provide a basic background in everything you need to know to be able to create a computer vision system, and train it to deal with the physical world.

This book gives senior undergraduate and beginning graduate students and researchers in computer vision, applied mathematics, computer graphics, and robotics a self-contained introduction to the geometry of 3D vision; that is the reconstruction of 3D models of objects from a collection of 2D images.

Creating Polygonal Shapes through a Merger with Topology
By merging the traditionally distinct fields of topology and geometry, through the discovery of a new type of mathematics called persistent homology, math researchers have created a set of equations which simply describe the pattern and placement of complex fractals as part of a polygonal model - such as the unique froth on a wave, within the reach of real-time rendering

Cells with double vision
Unlike in the peripheral nervous system, where cells are often unable to distinguish which branching pathway an electrical system is travelling from, the central nervous system makes use of sophisticated internal networks not too dissimilar from an IP record, to differentiate between nervous pathways.

This book is very much a holistic first-timer?s guide to creating a hideously complex system ? a full virtual reality. The book describes a VR system as ?a system that provides a synthetic experience for its user(s)?, a definition which could not possibly be any broader.

A Realistic Equipment System
One person?s take on creating an inventory system that emulates reality.

Virtual Manniquin - You!

Industry news, originally posted 02-02-2004, deemed too important to allow to fade. Tired of battling with wardrobe accessories in crampt changing rooms? Fed up of trying oh-so-carefully not to damage items whilst your body does its best to get in the way, and the stall is falling apart around you? VR may have a solution, in the form of a system developed by Toshiba. The company is developing a 3D, realtime system uses video cameras to create a virtual copy of your body on a screen, and not only moves with you, just as a mirror would, but also tries on clothes, without you having to. The system is still at an early stage, but it could in use in stores within three years.

The human brain is the ultimate legacy system, with bodges, klonks, workarounds and kludges forcing it to work as a (mostly) cohesive system.

SonixTouch is a portable touch screen system, that can be customised by the clinician, into any display method, and compatible with any general purpose or specific ultrasound medical system. It adapts to process the results from anything.

Improving LIDAR: Calibrate and Scan
A new technology currently being trialled by the EU, seeks to substantially improve the LIDAR machine vision system's accuracy. To enable the system to differentiate between moving and stationary targets, and prioritise where to scan.
