X3D

X3D is a specially designed for the world wide web and design of three-dimensional image markup language.Universal Extensible 3D (Language ), by the Web3D alliance to design, is the latest VRML standard upgrade version.X3D based on XML format developed, so it can be directly use the XML DOM tree, XML Schema check technology and related XML editing tools.The X3D has been certified through the ISO international standard.

The characteristics of X3D

VRML and X3D have several follow graphics hardware development upgrades stage most of the Direct3D 9.0c and OpenGL 2 GLSL function effects can be achieved.X3D specification to support graphics hardware functionality is added from the underlying rendering nodes, such as support for triangle, triangle fan, triangle strips and other basic rendering elements ; such as support for setting video mixing mode and set the frame buffer and depth buffer, the template cache function; and the nodes can support multiple texture mapping, and many times support Shader coloring, support multiple render targets ( MRT), support for instance (Geometry Instance) geometry.2010 is already available in X3D and VRML use deferred shading technology.Now the special effects including SSAO and CSM shadow, reflection and refraction, real-time environment based on real-time environment and skylight illumination, HDR, motion blur, depth of field.X3D supports 3ds MAX standard materials a variety of textures.

The X3D through the DIS component or Networking components to support multiple users sharing scenes and events.There are several X3D engine can support ODE physics engine or PhysX physics engine.

Editor this paragraph of X3D and other real-time 3D engine comparison

And the most popular Web3D engine, VRML and X3D market share is not high.This is not because X3D technology itself flaw, and X3D is the main production tools and development environment is relatively backward.Previous support WYSIWYG VRML real-time development environment for Cosmos World, ISA, Avatar Studio because of the development of company's steering and did not continue to develop, and behind the development of the BS Editor, Flux Studio, is not perfect.In addition X3D also did not provide perfect function package, while Quest3D, Unity3D, 3D VIA Virtools provides perfect functional package.

Internal rate of return(IRR)

Internal rate of return ( IRR) is a measure of the private equity investment performance of the appropriate reference.In short, the internal rate of return is expressed as a percentage of time weighted returns.Internal rate of return for cash withdrawal ( investment) present value, distribution ( return on investment funds) the present value, unrealized investment present value calculation requires the calculation of the discount rate.

Asset allocation

Refers to a portfolio allocation ratio shows the investment in distribution between different asset classes.Relating to asset classes including stocks, bonds, property, cash and overseas investment.Institutional investor asset allocation, objective is to balance the risks, to ensure that the portfolio diversity.Diversification of assets can bring different rewards, such as the return on a bond is low but stable, equity returns but higher risk, cash return is guaranteed.Effective asset allocation to maximize the return and liabilities covered.

Mini projector

Mini projector called pocket type projection, TRT-3M portable projector, the traditional large projector compact, portable and miniaturized, entertainment and practicality, the projection technique is more close to life and entertainment

What is a miniature projector

The so-called mini projector called pocket type projection \ portable projectors, in foreign countries have a special word ( Pico-Projector) as its name.

Primarily through the LCOS RGB tricolor projector and 720P decoding technology, its general weight does not exceed 0.2Kg, some even don't need fans or super little mute fan cooling.Can carry ( can be put in the pocket), the screen can be projected to the 40-50 inch or more, so sometimes we called miniature projector or pocket projector, portable projector, mini projector, handheld projectors.

Use and maintenance of miniature projector

1 open the reflector cover gently to the largest angle.The action is too large will damage the cover projection, resulting in micro projector cannot be used.

2 turn on the power switch, the bulbs should be lit, fan should turn ( with the hand in a mini projector outlet feel wind conditions or to listen to the voice of judge ), such as the fan does not turn, should turn off the power immediately stop using it.

3 open the miniature projection cabinet cabinet cover, handle with care.The mini projector and screen distance maintained at 1.5 - 2 meters.In the setting of all operating switch is in the off state after the power is switched on.

4 grasped the supporting rod bracket ( clip ), on the supporting rod is pushed as far as the projection surface of the vertical, at this time will have " card it " sound, that support rod is already in place.Attention action not violent.

5 adjusting reflecting mirror, a focusing knob, color adjustment knob, culminating in the screen get clear white light.

6 in the projection table placed slides, adjusting the focusing knob, so that the screen image clarity.( used with powder projection film, should make the film face up)

7 after the use of the power switch off.A hand support rod, a supporting rod bolt hands up, then slowly down the support rod to the support rod is fixed on the bracket ( clip ).

8 dustproof cover, the power line close to the cabinet, close the door.

Mini projector impact on several major areas

2 business office: instead of a large projector, company meeting function; large projector price is 4000 to 14000, the bulb life of 1000 hours, is not convenient to carry, mini projector, the price in 3000 yuan, the bulb life of 30000 hours, 3 years time does not need to change the bulb, convenient carrying, clerk to the demonstration of new products only need to take micro projector, which can reach the effect of demonstration.

4 instead of a TV function, directly connected set-top box television, the day when 30 inches of TV watching, night when 80 - 100 inch TV, reach home theater effect ; easy to move, break through the traditional video space, even if you are in the mountains, also can and lover to share today's TV series, movies, MTV.Micro cast no radiation on pregnant women, short-sighted people do sufficient protection, its low power consumption function, relative to the color TV power consumption 1 / 1000000

5 teaching: training session, classroom teaching; traditional projector is not easy to carry, classroom as student's naughty, the projector is placed in the classroom is not safe, easy for students to break, mini projector portability for teaching vacancy, later the teacher only need to put the data stored in the projector can show students teaching eliminating the textbooks and with pen and chalk handwriting trouble.

The present micro projectors home theater effect, already occupied the 50% home theater market share, from 2009 to 2010 in a short span of one year, the projection to home theater into the forces had defeated the TV to occupy the market peak, especially its unique CMMB function and then watch TV set top box function, processing the built-in storage, you can download the latest network film and music and other functions, is the color can not be replaced, mini projector will occupy in the future market of domestic movie theater.

In addition, micro cast no radiation on pregnant women, short-sighted people do sufficient protection, its low power consumption function, relative to the color TV power consumption of 1 / 1000000, even 1 years TV also can use TV watch 1 days of electricity, fully the impact of safety, environmental protection, health and other indicators for the future social development make amazing contributions, standing in the green world peak as a leader.

Grid service

In the web service service on the basis of the " service " concept, it defines a set of interfaces, the interface is defined clearly and adhere to specific practices, used to solve the server found that dynamic service creation, service life cycle management, notification and service life cycle related problems.

Grid service markup language ( Grid Service Markup Language, referred to as GSML) based on XML is a grid application programming ( describe ) language support grid client "on-demand" programming, based on reusable component and event driven approach to describe the grid application flexible processing logic and cooperative work mechanism.GSML projects including the GSML language and related tools.

GSML language concept in Pipe, Event, EventSet inspired by PI algorithm, through which users can be unified asynchronous event communication mechanism to describe the user end of various software components and grid resources interactive relation between them.GSML tool set includes browser and editor (download ).The browser to run by the GSML language application procedures; editor used to write GSML program.

GSML's goal is to become a kind of simple and easy to use grid programming language, can be flexible, effective integration of grid resources, but also provide grid resources, applications and users work together to infrastructure.

Secondary stock

This word is used in the venture capital and private equity limited partnership interest of the original investors, because the original investors intend to limited partnership before termination of investment will be realized.The original investors may be for a variety of reasons to sell their holdings of private equity shares of the company, such as cash, had changed the investment strategy or key, or need to rebalance the portfolio.For investors, pay attention to secondary unit is the main advantage of them can not be like investment primitive so long time to invest in private equity funds.
