1.多种发型,胡须,特征(耳朵,嘴巴等)的几何Chunk集成在一个人物模型文件内部.
2.多种手腕护甲,腿护甲,鞋子,披风的几何Chunk集成在一个人物模型文件内部.
3.集成的模型块(GeoChunk)按数值区域进行分类,如设发型块的标识范围为1-100,胡须101-200,耳朵701-800,大腿1301-1400,小腿501-600.在各自的取值范围内,不同值代表不同的几何形状风格,如1:光头,2:冲天发等等.
4.手腕护甲,腿护甲,鞋子,披风物品应该有数据表明自己影响了哪些集成模型块(GeoChunk),如长筒靴影响了小腿的几何形状风格.每样物品均能影响身体的各个部位,若各个物品影响出现重叠,取影响优先高的物体.如靴子影响小腿是最高优先的,其他的影响被冲消.
5.武器,护甲,盾牌作为外部模型连接到身体的某块骨骼,以之为根骨骼进行骨骼矩阵运作.每个人物模型定义了其使用各种武器,盾牌时的动作.每个人物模型定义了各部位的物品接入点标识和坐标,如1:右手心,2左手心,并且定义接入的骨骼ID.
6.每样物品,鞋子,披风,武器,护甲,盾牌除几何形状外,有数据定义各自的纹理,极其复杂.一个物品应该有左右模型文件,左右纹理文件,以及对身体各部位影响的几何形状风格和对应的纹理.
7.头发的颜色使用不同的纹理来表达,但毛发纹理不仅表达颜色,还表达毛发的外观风格,如辫子,四披头,长发等不同发质,数据组织极其复杂,分性别,种族,发型,颜色值等等.
8.人物模型分块应该以Material为基本标准,兼顾几何形状(GeoChunk)分布,Material在存储时要预排序.1个Materail可以影响多个几何Mesh,一个Mesh可以受多个Material影响(多重纹理).
9.1个Materail用Flags(1个或多个DWORD)表达自己的Shader,这样使用Flags就可以排序优化模型渲染队列.基本有:BLEND_NONE,BLEND_TRANSPARENT,BLEND_MERGE,BLEND_ADDITIVE,BLEND_ADDITIVE_ALPHA,BLEND_SRC_DEST等等.甚至可以是一个VS,PS的Shader ID.

繁琐沉重的工作麻木了程序员的思维，也只有在完全属于自己的闲趣的代码中才能找回自己的方向和热情。 留下些足迹，让未来的自己，体味现在与曾经的彷徨和执着。 嗨，我梦萦的Kalimdor大陆.  Reference:

1.树型文件结构不过是为人便于管理使用而制造的假象,实际文件格式坚持以数组存储，通过某种假象信息表达出树型结构，如路径名。 2.坚持读取效率至上原则，添加编辑删除效率次之，文件大小用一个终极优化整理操作完成。 3.坚持哈希表结构,使用加密密钥形成实际的不同文件格式。 4.设计上要考虑多语言化支持，多格式压缩，与本地文件系统操作完全兼容,无缝链接。 5.Great thx to Ladislav Zezula's http://www.zezula.net6. http://www.soarchin.com的MPQMaster做的不错,用Upx压缩,自称最小最快,嘿嘿我的程序也一样. 7.文件数据结构无非: a.HEADER b.DataChunk(tag,offset.size) c.StructArray

XML UI排版实现思考
1.每个UI元素要根据其父元素的既定位置进行对齐偏移,所以在代码逻辑上父元素应在自身导入完备后,再行导入其子元素.(两阶段载入,good solution)
2.由于一个复合元素内的子元素来源不同,继承而来,组合而来,组合继承而来,导致确定子元素最终位置的复杂性.
3.文字的渲染性质与纹理类同,而纹理的Size由脚本数据预指定,文本的Size则在初始化时动态计算决定,设置可变文本在每次文字变化时需再次计算决定,然后这两个类同逻辑应在同一个加载阶段完成,以保证逻辑的协调.
4.a.虚元素的属性的有效性取决于InheritPropertyFrom函数实现.
b.逻辑上,虚元素只能定义元素的样式,大小,对齐偏移,而不能定义具体位置,或具体文本内容.
c.无大小定义的纹理,其大小决定于其所依附的元素.
5.对于虚组合元素,如按钮等,它的所有子元素均为第2层虚元素.
6.对于多重复合继承,依靠严格遵循如上准则,多重组合继承应该在逻辑上自然实现.
虚元素的逻辑定义层次
1.只有样式,没有对齐偏移和Size的虚元素为第1层.
2.有对齐偏移或Size的虚元素定义的虚元素为第2层.
3.组合了其他虚子元素的虚组合元素为第3层,如一个虚的按钮的NormalText元素也是个虚元素,同时NormalText又继承于某个FontString元素.
4.复合的Frame元素为第4层.

基本设计格式
1.定义字符串长度为: strlen(szText) + 1
2.所有偏移位置均指以文件头为起点.
3.文件存储各段数据实际以16字节对齐占用,即若strlen为16,加尾部\0字符,长度为17,但实际要占用32字节. 即,除非该段Offset为0(无数据),则该段至少占用16字节的整数倍空间.

0.XML+Lua,格式和逻辑,强强联合.
1.FrameXML.toc线性顺序加载,出log.
2.每个XML文件描述一项界面元素,关联脚本使用"file="语法.
3.Interface.mpq内为原始版本,在主程序目录下可以创建一个定制版本目录.
4.编辑工具:XMLSpy
HTML UI解决方案
1.使用纯HTML网页界面.(XML描述C++图形界面系统)
2.使用javascript脚本.(Lua 脚本)
3.使用window.external提供COM服务体系入口.(Lua 脚本引擎环境)
4.使用动态绑定IDispatch技巧将一个普通的C++类暴露为动态COM对象.
5.使用执行函数脚本达到事件回调的效果.(Lua脚本执行)

1. A new m2 model renderer that can show most model skin texture set, add particle system effect, texture animation, npc skin.
2. Add two mpq edit functions in the pop menu by right clicking on the file tree item.
Import File: Import a single file directly from local file system under the clicking tree node.
Import Folder: Import all files in a directory from local file system under the clicking tree node.
3. Wow data path config is automaticlly set to where you open your mpq file now, no need to set it manually.
