原创 定语从句

限定性:从句部分系主句意义中不可或缺的部分There is one point where id like your advice.非限定性:附加说明作用I have many friends, some of whom can play guitar very well.    

原创 -_-!!~~~好像比较地基础....看快点才行....

原创 数理应用 1.4 交线

// find the point of intersection between two lines 点斜式,两直线不平行float *lineIntersect (float *L1point, float LiSlope, float *L2point, float L2Slope){float temp[2] = {0, 0};//solve for our x value

原创 数理应用 1.2 1.3 线

直线斜率:float SlopeBetweenPoints (float *p1, float *p2)  //???浮点数组???{return (p2[1] - p1[1]) / (p1[0] - p2[0]);}判断垂直: // to determine the slope of the line perpendicular(垂直) to ourselvesf

原创 数理应用 1.1 点

检测输入的整形数是否为2的乘方:Bool powoftwo (int num) {return !(num & (num -1));  //嗯嗯,记住}右手直角坐标系;点类型结构:Float 3dpoint[3];Struct 3dpoint {Float x, y, z;3dpoint operator + (const 3dpoint &p2

原创 努力向物理引擎方向蠕行....

希望电子出版社的...图书馆借的...哈哈...浏览了一下~~其中的数学物理知识基本都在高中学过...不过在编程中没应用过多少,还是认真看的好...打好基础...嗯嗯~~~在这里做做笔记...
