浅谈3D游戏模型与贴图技术
浅谈3D游戏模型与贴图技术 摘要：优秀的模型为工作提供了一个好的开端，合适的贴图会使这个模型锦上添花，一个好的游戏模型是优秀模型和优秀贴图的结合体，二者相辅相成，缺一不可。 关键词：3D游戏；游戏模型；游戏贴图；游戏美术；模型贴图制作流程 在多样的游戏类型中，电视游戏是对游戏画面质量要求最高的一类游戏，这是由于电视平台的自身特点决定的，由于目前电视分辨率普遍较高，因此也需要电视游戏在制作开发时，必须考虑画面质量，而画面质量的好坏又直接取决于游戏中模型的品质和贴图的品质。模型的精细度和贴图的清晰度都会给玩家直接带来视觉上的美感，加强画面视觉感染力。这样的电视机游戏也通常被称为次世代游戏。本文将针对次世代游戏中的游戏模型和游戏贴图技术进行讨论。 一个优秀模型制作前要做好几项准备工作，首先要全方位的了解这个模型。以角色类模型举例，要做某一个角色，就要做到了解它的外貌特征、性格特征、生活背景等。优秀的角色模型应该是具有一定生命力的，而且要体现出它的特点和地域文化。这种想法和理念应该贯穿原画设计、3D模型制作和动作设计始终。这三个方面共同塑造着角色的这一特点。在建模的时候要时刻感觉它的生命的存在，感觉它的性格以及情感动作等，这样才有可能做出一个具有生命力的高品质模型作品。 游戏模型按精度的不同，可以分为高模和简模，制作高模的意义在于生成法线贴图，法线贴图会携带高模的表面起伏信息，把这样的携带高模起伏信息的法线贴图再回贴给简模，这样简模也具备了一定的高模特征，这就是游戏中应用简单模型却可以表现出足够多细节的基本原理。无论是高模还是简模，都要具备一些最基本的要求，如造型准确、布线合理、形神兼备等。 一个优秀的建模师应该注意对事物的观察，如角色建模师就应该平时多观察肌肉结构、骨骼特征、动作动态，分析不同动作给肌肉和骨骼带来的不同影响等。了解这些内容需要配合一定的解剖知识。模型的质感表现也是一个不容忽视的内容，如钢铁、青铜、麻布、丝绸、皮肤等，不同质感给人不同软硬度的直觉。对于某一种质感由于或崭新或破旧，或华丽或古老等差异，也给模型塑造带来不同的要求。对生物体的塑造，结构必须是合理的，在游戏的生产流程当中，建模师要参照原画师做的原画设定来进行三维建模，而事实上原画师提供的原画往往只是一种意象上的构思，不具备太多的细节，而对模型的细节刻画往往都落在建模师肩上，建模师需要对结构进行补充，这个过程也是对角色的二次设计。 如果把模型比喻成卸妆后的女人，那么贴图的过程就可以看做是给这个女人化妆的过程，行业里流行着这样的一句话“三分模，七分贴”，可见贴图的重要性。一个次时代模型所需要加载的贴图最基本的有三张，分别是固有色贴图、高光贴图和法线贴图。不同的贴图放置在不同的贴图通道中，分别起着各自不同的作用。固有色是指物体在正常光线下所呈现出来的颜色。对于一个物体，它自身的固有色是尤为重要的，一个物体受到光照后，固有色主要表现在受光面和背光面之间的中间调部分，也是素描中常提到的明暗交界线部分的颜色，因为这部分受外部环境色影响较少。而固有色贴图的任务就是把物体表面不受外界环境影响的固有色表现出来。绘制固有色时，要观察实物或原画，分析物体的质感、不同材料的搭配以及物体表面的新旧等等。高光贴图主要来影响物体表面的反光特性。高光

@3D网络游戏的发展史
3D网络游戏的发展史 3D网游的特点是立体感强，具有较高的真实性，对玩家来说有更好的游戏体验。随着玩家游戏年龄的增长，会逐渐出现“2D回合制---2D即时制----3D即时制”的转变。因为2D 回合制以及2D即时制对于游戏开发的难度较低，所以一般进入网游开发行业的都是先从这里做起，客观条件下2D回合制和即时制的竞争压力会越来越大。现在的3D网游的开发成为了网游的未来的战略高地。 第一代3D网游(又称2.5D网游，或假3D网游) 第一代3D网游从游戏体验上来说并不比2D即时制强多少。仅仅是在2D即时制网游的基础上对于场景贴图使用了3D效果，部分网游有游戏人物动物模型的翻转效果。对体验者而言，第一代3D网游跟2D网游几乎无差别，但其技术上来说第一代3D网游已经说明其开发实力进入3D时代了。可以认为，第一代3D网游属于网游开发商在进入3D时代的垫脚石。从运营上来说第一代3D网游是在跟2D网游抢市场，但如果走自主研发路线第一代3D网游又是不得不经历的体验。 国内运营的第一款3D网游是《精灵》，它属于第一代3D网游，但是因为引擎上的漏洞导致BUG过多终过早夭折。 随着越来越多的2D网游开发商的转型，一部分较为成功的3D网游出现。例如网易的《大话西游三》和《大唐豪侠》属于3D场景贴图;巨人网络的《巨人》属于3D贴图3D人物;以及国家816项目3D引擎开发出的《天龙八部》等都属于3D贴图3D人物。 第二代3D网游 从体验效果上来说，第二代3D网游已经算是正式步入3D时代。玩家可以自由翻转视
角，技能效果出现了“面向错误”的判断，出现真实的可供攀爬的山坡，甚至因为设计的原因玩家能被“卡”在地洞里面。而因为依然采用2D点对点算法模式，所以在动作表现上依然不尽人意。例如：你向B发出的子弹或者火球，而C在你和B之间，但是效果是C没有受到任何伤害，并且B无法“闪躲”开你的子弹或者火球。第二代3D网游保留了对战斗判定的特点是先选中然后攻击。 在中国大陆运营的第一款第二代3D网游是《笑傲江湖OL》，因为已经具有与2D网游截然不同的效果，所以在很短时间内就聚集和很高的人气。但是因为引擎的不完善BUG丛生，甚至用游戏修改就能修改游戏很多参数，终于在风靡一时之后停运。 第二代3D网游已经以其较好的体验效果在国内占据了不少份额，并且随着玩家群网龄的成长，第二代3D网游越来越容易被更多人接受。暴雪的《魔兽世界》.完美时空的《完美系列》.网易的《天下二》都是第二代网游的佼佼者。 第三代3D网游(又称真3D网游) 第三代网游现在可以被称为动作3D网游，现阶段的第三代网游基本都是动作网游，例如《RUSH冲锋》。 比较第二代3D网游有了更好的体验效果，代入了载体理论，让网游的战斗效果更加具有真实感。玩家放出的远程技能不再是必中目标，也不再会无视型的穿过第三者的身体，甚至近身战斗也变成因为动作轨迹造成群体命中判定。还记得《街头霸王》里面小白小红的大馒头以及印第安人的喷火球吗?那个其实就是载体在横板游戏应用上的成功例子。 第三个3D网游的共同特点是：1.视角多为第一人称或者固定于游戏角色后上方的第三人称视角;2.取消的选中目标的概念，取而代之的是类似于CS一样的准星瞄准目标。 中国第一款第三代3D网游是天联的《天之游侠》，同精灵和笑网一样，当第一都命苦。《天之游侠》也具有很多难以修改的重大BUG导致在线并不多，由于游戏的真实体验感而

三维游戏模型基本规范
教程] [三维]游戏模型基本规范（转） 2011-04-19 11:15:15 [三维]游戏模型基本规范 经常看见模型要求多少多少面这样的制作要求，那么你们是怎样计算面数的？ A 通常我们提到游戏模型的面数都是指的三角面，而通常在你在3D软件中所看到它计算的面数都是四边面。一个四边面等于两个三角面，但并不是说你想了解你的模型有多少面就直接将你看到面数*2就行了。因为如果你的模型中还有三角面的结构甚至大于四条边的结构（当然这是不允许的），你所计算的面数就会有所出入。所以保险的办法还是将你的模型先用工具转换为全三角结构后再看他的面数。在3DSMAX中你只需要很简单的将他塌陷为Editable Mesh就可以了。 Q 那么一个游戏角色通常要求多少面呢？ A 那要看这是一个什么游戏了，还有他使用的什么引擎。比如格斗游戏每个角色的面数就比动作游戏多很多，因为格斗游戏整个画面通常就两个人，而动作游戏同画面会有一大堆人出现。而网络游戏角色的面数就更为节约，因为几十上百个玩家在同一画面出现并不是什么新鲜事，为了不让玩家的机器因此而卡住他们只好最大限度缩减角色的面数。再一方面，主角的面数通常比配角多，配角的面数又比敌人多，但是有一个例外，那就是BOSS，BOSS的面数可能比主角还要多。为什么呢？因为决定一个游戏角色的面数并不完全是按照角色本身在故事中的重要性的，而是按照这个角色在出场的时候同画面可能会有多少角色出现。而在BOSS出场的时候，通常只有主角和BOSS两个人而已（喜欢带着一堆小敌撑腰的没胆BOSS除外），所以BOSS可以有很多面。而主角则不一样了，他贯穿整个游戏，如果他的面数太多，遇到同屏幕有很多敌人的情况，游戏就会很卡了。说到这个问题，有人又会问照这么说主角的面数应该非常少，但是为何在一些特写镜头的时候看着这么细腻呢？这是因为在游戏中通常会为主角制作几
