What is demonstration

Overview of Demo

Demo is the abbreviation of demonstration, the demo on the computer is simply to show the computer graphics and music program, so the beginning of the game animation Show is a demo. At a computer company, you can see a computer showing the software and hardware programs that are commercially available, and these demos are designed to attract customers with graphics and music to reach the goal of publicity.

But if it's just a general demo, then there's nothing to look at. Here the main introduction of the demo does not refer to the commercial demo, but in international competitions, there is a group of participants specifically for the demo game produced by the demo. The main purpose of these demos is to bring appreciation to the visitors and play the computer in drawing and music. In other words, demo combined with stunning CG and music, in addition to the demo maker's programming skills and skill, show a lot of difficult performances. Some people say the demo is: "Dear, I turned the PC into a SGI." "The winning demo is designed to optimize the program, give full play to the PC's hardware potential, and produce amazing results, including: changeable music, Rener graphics generated by real-time operations, Fractrl, transparency, plasma,3d VECTOR space,virtual Reality,morph and so on. §demo features § To achieve these effects, these demos typically have the following four features:

⑴ Use assembly language, to produce a simple demo, with high-level language can be easily written out, but because some limited speed is not ideal. The use of assembly language optimization, can give full play to control hardware and software hungry power.

⑵ music with multiple channels.

⑶ break through the traditional graphics ability: on the PC Standard VGA in the 320x200 resolution can only show 256 colors, few memory pages, causing a lot of restrictions. Demos often use special patterns, usually called x mode, which can achieve 320x200 256-color multiple memory pages in these modes.

⑷ real-time operations: In these demos are mostly vector space, virtual reality, or have a lot of computer color effects, and deformation and so on. Because of the real-time operation of the relationship, although a demo is not large, you can broadcast 10-20 minutes. §demo Creator §demo is like a game, any demo need to have program design, art staff and arranger staff. Often in the way of demo team to prepare demo.

A demo group usually includes:

⑴ leader Organizer: Overall planning to lead the team

⑵ Programmer Coder: Design Demo Program

⑶ composer musician: creating music to match demo content

⑷ Art GRAPHICS ARTS: Drawing demo Graphics

⑸ Other personnel: responsible for BBS and assist, etc.

(It's like the game development team, isn't it?) §demo World's big Rally § "International demo Competitions" International demo contest, usually organized by the larger demo team to host the event, including Demo,intro (less than 64KB demo), Music and graphics.

Different races are usually held for different kinds of machines. Winners are awarded prizes or sponsors by voting.

The current well-known demo competition:

Assembly Finland ends every summer

The party Danish Christmas

The Gathering Norway before Easter

The Computer crossroad Sweden before summer

§ "DEMO" § in software

In the software version, demo is the demo version, this is generally divided into two, one is full-featured but there is a time limit, most of the 30 days, 30 days later will require you to continue to use the purchase, the other is the formal version of the experience provided before the release, this version has no time limit, but most of the function is incomplete, The most common is the game demo.

"DEMO" § in the game

An incomplete version, usually called a "demo", is released before the official version of the game is available for publicity and stress testing. Usually the demo game has a smaller capacity and allows the user to experience the contents of the game beforehand, allowing the user to make a better decision.
