(贴进口)为什么Xcode不能识别余弦?
#include <GLUT/glut.h> //must be included for OpenGL
#include <Opengl/gl.h> //must be included for OpenGL
#include <math.h>
#include <time.h> //must be included for time functions
#include <iostream> //must be included for console input/output
#include <fstream>
void ShowMapCircle2()
float radius =300;
float theta = 0;
for(int i=0;i<12;i++)
{
glPushMatrix();
glTranslated(radius*cos(theta), radius*sin(theta),0);
glTranslated(360,250,0);
glRotated(-90+i*30,0,0,1);
glTranslated(-360,-250,0);
glTranslated(360,250,0);
glScaled(0.4,0.4,1);
glTranslated(-360,-250,0);
ShowUSMAP();
glPopMatrix();
theta += 30*3.14159/180;
}
}
的Cos不被认可的Xcode。我不知道发生了什么事。我得到“使用未声明的标识符'cos'。”我确定这很简单,但我无法弄清楚。 'cos'似乎想在xcode中定义?
glTranslated(radius*cos(theta), radius*sin(theta),0);

构建。虽然不会显示。 – Henry 2012-03-13 16:19:40
