Physics Processing Unit
A physics processing unit or PPU is a processor which is designed to take all real-time physics computation from the main processor. This frees up the CPU for other tasks, and significantly increases framerate.

The GPU, or graphics processing unit is the heart of any 3D accelerator graphics care. It is a powerful workhorse, frequently more powerful than a PC?s CPU ? central processing unit ? and dedicated solely to graphics. The pace of GPU advancement has picked up substantially in recent years, with Nvidia and ATI Technologies, going at it hammer and tongs, to try and outdo one another.
A worthwhile look at the benefits of using C++ over C for complex tasks, such as physics.
There are a large number of new developers coming into the market for physics engines that need help through this complex process. Current introductory books are inadequate; they don't bring enough real-world programming experience to the task. There is a need for an introductory book on game physics with solid coding guidance but which limits the math content. This book tries to fill that void.
The PhysX SDK and related hardware acceleration is designed as a method for realtime physics calculations, rather than expecting every developer to code from scratch.
The Matrix distorts when a freak corruption of data creates a no-physics zone in a thin layer paralleling the floor. An advanced replication of gravity warping accidents that happen in ActiveWorlds and Second Life, today.
Running is not as simple a process as it seems at first glance. The physics of this type of movement is very different to the physics of walking, and as a result the leg and body movements are radically different. If we wish to recreate realistic running in either embodied robotic form, or via sequences for VR, then we need to understand this process intimately.
Whilst over 30 years old now, this book is one of those whose usefulness is never likely to fade. It is a physics book, dealing with the mathematics and physical constraints of getting any rigid body jointed system to move as desired. Designed initially with robots in mind, long before the avatar, the maths contained within is ideal for grounding on ragdoll physics as used with avatars.
Released December 2005, the CyberMan GVD510-3D head-mounted display is a stereoscopic display unit, with a resolution of 640 x 480. Made by Kopin Corporation, China, this unit is essentially part of the new trend of video eyewear, combining HUD and HMD in one device.
