Binary Space Partitioning

Binary space partitioning, or BSP, is a method of organising 3D areas so as to minimise the amount of data sent to a renderer. It only works for environments in which it is not possible to see one part of the environment from another. It is thus used a fair amount, in games where the world is a series of discrete rooms. Use in other VR environments is possible, but only as a subset render for a specific volume, it breaks down otherwise.

BSP works by sub dividing the 3D data. Area A is subdivided into areas B and C, as separate memory blocks, providing that no area of B can be seen from a render of C and vice versa. If one or more of the areas still contains a large number of objects, it will be subdivided again if possible. So, area C becomes areas D and E, providing that no area of D is visible from E, and vice versa.

Messing with Tangent Space
Tangent space is sometimes called texture space. It is the co-ordinate systems for one face of any 3D skinned model. Use of tangent space, which this tutorial covers, is necessary to properly map a texture onto part of a 3D shape.

Augmented Reality, Designed for Space, Half a Century Behind Everyone Else
The European Space Agency (ESA) have released details of a new augmented reality interface they have been testing and how it actually benefits astronauts when in space. Quite scarily they actually believe they are the first organisation to implement an AR interface, according to their press release.

This tome, written long before the Metaverse Roadmap, was one of the first large works to discuss how virtual spaces create entirely new kinds of space, and require mapping constructs and methodologies utterly alien to what had come before.

The Drive for Storage Space and Speed
More music; more films; more photography; more, more, more. More of everything seems drive this fetish for storage space and power. Yet is it just more, more, more, or can more actually equal better in VR?

Sensor Web: A look at an Internet in Physical Space: AR Orientation
The Sensor web, is a long-anticipated faced of an augmented world. It is, in theory at least, a huge web of interconnected sensors, actuators, RFID, GPS, specialised routing controls, and augmented sensory hardware, all wired together into an immense web in physical space, facilitating Augmented Reality applications.

Spatial Representation of a Virtual World
How do you perceive space and spatial relationships between objects in a virtual environment. Rather easily if you are setting out to replicate the physical world. But that is too easy, it loses so many of the true advantages of VR, where space is irrelevant, and every room can be a TARDIS. This article looks at mapping that kind of a mess, beginning with text worlds, where such spatial irrelevancy is at its highest.
