class Map Instruction:
地图(Map)有2个部分组成:地形(Terrians)和物品(Object)
地形有个2个基本划分:地块(TerrianPlate)和纹理块(TexturePlate),他们都是正方形
一个TerrianPlate的边长(m_fTerrianSize)为1.0f,
而TexturePlat的m_fTextureSize为4.0f
也就是说,TexturePlate含有16的TerrianPlate.
TerrianPlate的作用是体现地形的高低,是Map的基本逻辑单位
TexturePlate的作用的是体现地面的外貌,Map的顶点储存是按TexturePlate来安排的
一个Map的逻辑尺寸(TerrianPlate的个数)必须是4的倍数
一个TexturePlate含有25的Vertices,构成32个Faces,所有的TexturePlate都使用相同的Indices
也就是说,在Render时,是对每个TexturePlate分别Render
m_pHeights用来储存Vertex的高度,尺寸是(m_TerrianWidth + 1 ) * (m_TerrianHeight + 1 )
m_pTerrains用来储存TerrianPlate的逻辑属性,尺寸是m_TerrianWidth * m_TerrianHeight
Map中X的正方向为Width的正方向,Z的正方向为Height的正方向
下面举例说明说明:
如一个逻辑(TerrianPlate)上8 * 8 的Map,TexturePlate为2 * 2

Map全部采用的的行主存储
处于TexturePlate边上的Vertex显然是重复的.
Vertices按TexturePlate储存在VertexBuffer中
这样的结构对逻辑-物理转化是带来的不便.
比如Vertex(5,6) 的 Height可以直接求得 m_pHeights[6 * (m_TerrainWidth + 1) + 5]
但它的在VertexBuffer的位置则这样计算:
TexX = 5 / m_fTextureSize;
TexZ = 6 / m_fTextureSize;
InTX = 5 % m_fTextureSize;
InTZ = 6 % m_fTextureSize;
Offset = m_nTextureVertices * (TexX + TexZ * m_TexturesWidth) ; 该TexturePlate的基位置
Offset += InTX + InTZ * 5; TexturePlate内的Offset
