厄。。无聊把卡通渲染写了一下…一次就成功了 – -||这值得高兴么…一个是从光照方向看前面，一个是后面。
shader写的很屎
uniform extern float3 gLightVecW;
uniform extern float4x4 gWorldViewMatrix;
uniform extern float4 gColor;
struct OutPutCartoonVS
{
float4 position: POSITION;
float2 uvCoords: TEXCOORD;
float4 diffuse: COLOR;
};
OutPutCartoonVS CartoonVS(float4 p:POSITION,float4 n: NORMAL)
{
OutPutCartoonVS outPut = (OutPutCartoonVS)0;
outPut.position = mul(p,gWVP);
float4 LightDir = float4(gLightVecW,0.0f);
n.w = 0.0f;
LightDir = mul(LightDir,gWorldViewMatrix);
n = mul(n,gWorldViewMatrix);
float u = dot(LightDir,n);
if(u<0.0f)
u = 0.0f;
float v = 0.5f;
outPut.uvCoords.x = u;
outPut.uvCoords.y = v;
outPut.diffuse = gColor;
return outPut;
}
technique CartoonTech
{
pass P0
{
vertexShader = compile vs_2_0 CartoonVS();
}
}

e..My second shader program。。。use effect technique,diffuseLight+ambientLight+specularLight+Texture
,so shit for Master,but i enjoy it…..

今天用vs05调个程序,结果一直蹦”debugging information for LightTextureCube.exe’ cannot be found or does not match. No symbols loaded”这个13点的提示，当时我就木了，不能debug？怎么可能？我检查了很多遍。。还是没发现哪儿有问题。。最后才发现Project->Property->Configuration Properties->Linker->Debugging->Generate Debug Info里的yes变成no了 = =。。我发誓我没动过这里，不知道为什么工程自己突然变动了…

prepering for my graduate school entrance examination ..
nothing ,…maybe i’ll spend some spare time on reading 3d tech books,but i know it’s harm to my exams..
so….i ‘ll continue this blog after the exam.
see u,my blog and my favorate game programing

All core codes comes from <<Focus On 3D Terrain Programming>>,with the help of this book ,i can do some easy cool terrain~~

the first pic is the effect that haven’t set texture,and the second is the one that set texture.
just load a texture and show it on different position and set alpha blend effect,make it like in a dream,
all codes come from Programming Role Playing Games with DirectX.

父母 Parents
十年前我们是父母的孩子
10 years ago, we were children of our parents;
十年后我们是孩子的父母
10 years later, we become parents of our children.
十年前我有温暖的家
10 years ago, I had a home full of joys and affection ;
十年后我才体会家的温暖
10 years later, I feel warmth of family then and not till then.
十年前我渴望离家去远方
10 years ago, I yearned for leaving far away from home,
十年后我渴望从远方回家
10 years later, I am longing to return my drifting heart home.

now i have finished reading <<Tricks of the windows game programing gurus>>,few weeks before,i said i will write a 2D game,but right now ,i changed my mind…..
here is the time to speed up to study 3D,there’s no time…
so come on…keep fighting.

After read capter 1 ofProgramming Game AI by Example,i write a 2DVector class,
// Vector2D .h
class Vector2D
{
public:
//求反向量
Vector2D GetReverse()const;
//求两个向量距离的乘方
double DistanceSq(const Vector2D &other)const;
//求两个向量的距离
double Distance(const Vector2D& other)const;
//调整x,y的长度不超过dMax
void Truncate(double dMax);

chinese edition,p275
特殊的语法–”替换调配(swizzles)”来专门用来完成这类不关心顺序的复制操作。
vector u = {1.0f,2.0f,3.0f,4.0f};
vector v = {0.0f,0.0f,5.0f,6.0f}
v = U.xyzw; //v = {1.0f,2.0f,2.0f,4.0f} ———> should be v = {1.0f,2.0f,3.0f,4.0f}
==========================
english edition is right,ok, i hate QingHua Press。
