摘    要

 隨著三維圖形技術(shù)的發(fā)展，3D游戲能創(chuàng)造更加真實(shí)、絢麗、壯觀的虛擬世界，帶給玩家更真實(shí)、強(qiáng)烈的視覺沖擊，電腦游戲目前正朝著三維空間、智能化、網(wǎng)絡(luò)化等多方向發(fā)展。 因此早期的很多二維游戲在如今多姿多彩的三維游戲中已經(jīng)黯然失色，如果能給在早期的二維游戲中加入三維和更多的游戲元素，便能給它帶來更多新鮮活力。
 俄羅斯方塊是電腦游戲發(fā)展史中早期最為經(jīng)典的游戲之一，經(jīng)常能在掌上游戲機(jī)、手機(jī)以及電腦上見到這個(gè)游戲。不過，以往常見的俄羅斯方塊游戲是二維平面上的，并且大多以黑白的形式出現(xiàn)，當(dāng)然在電腦上可以看到多中顏色的俄羅斯方塊。
 本課題在學(xué)習(xí)和研究DirectX 3D技術(shù)上，設(shè)計(jì)并實(shí)現(xiàn)三維空間的俄羅斯方塊。該程序?qū)崿F(xiàn)了俄羅斯方塊的基本功能，如移動(dòng)、變形、消行等，在程序中運(yùn)用了3D粒子系統(tǒng)實(shí)現(xiàn)簡(jiǎn)單的飄雪場(chǎng)景，這樣使得游戲不再單調(diào)，除此之外，在程序的渲染過程中使用了Vertex Shader技術(shù)，使用它來代替了固定渲染管道的頂點(diǎn)轉(zhuǎn)換和光照計(jì)算，按我們自己的方式處理頂點(diǎn)和光照。

 programming and realization of 3-dimensional Russia block
Abstract
With the development of 3-dimensional graphics technology, 3 D game can create a more real ,florid and spectacular world, bring the real, intense impingement to
players , computer games are developing to multidimensional, intellectualized, network-relation at present. Therefore many two-dimensional games seem eclipsed compare to the varied and graceful three-dimensional games , if we can change these two-dimensional games to three-dimensional and add more game element, these two-dimensional games maybe become vigorous.
The Russia block is one of most classical early game in the phylogeny of computer game , this game often can be seen on the palm game machine , mobile telephone and computer. However, in the past Russia block games are two-dimensional, and mostly just have two color, black and white。
the goal of this task is to  study and research 3D graphics technologies and the knowledge of the DirectX, then to design and realize the game of three-dimensional Russia block, This program has realized the fundamental functions of Russia block, such as moving , transforming , disappearing lines and so on, and create a snowing sense that make the game no longer monotony with a 3D particle system , besides, it use the Vertex Shader technology in process of rendering objects in the game, with this technology, we can produce the vertexes and pixels in our own way, rather then transforming and lighting vertexes in fixed function pipeline which use the fixed method to produce vertexes and pixels and the effect is not what we want。
Keywords: Russia block; Vertex Shader; 3D particle system; Matrix transform
