麻烦高手指点下

printf("\"________\"");

。。。。。。。无语   他的意思是   画直线

我也是刚接触openGL     要记好多...


这个是我写的
#include <stdio.h>
#include <GL/glut.h>
void init (void)
{
    glClearColor(0.0,0.0,0.0,0.0);
    glOrtho(0.0,1.0,0.0,1.0,-1.0,1.0);
}
void myDisplay(void)
{
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0,1.0,1.0);
    glBegin(GL_LINES);
        glVertex3f(0.25,0.25,0.0);
        glVertex3f(0.75,0.25,0.0);
    glEnd();
    glFlush();
}
int main(int argc,char * argv[])
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB);
    glutInitWindowPosition(100,100);
    glutInitWindowSize(200,200);
    glutCreateWindow("line");
    init();
    glutDisplayFunc(myDisplay);
    glutMainLoop();
    return 0;
}

其实没什么    都是球格式...

4楼的glutDisplayFunc我觉得应该传地址。

#include"GL/glut.h"
void myDisplay(void)
{
    glClear(GL_COLOR_BUFFER_BIT);
    glBegin(GL_LINES); 
    glVertex2f(0.0f, 0.0f); 
    glVertex2f(0.5f, 0.0f); 
    glEnd();
    glFlush();
}
int main(int argc,char *argv[])
{
    glutInit(&argc,argv);
    glutInitDisplayMode(GLUT_RGB|GLUT_SINGLE);
    glutInitWindowPosition(100,100);
    glutInitWindowSize(400,400);
    glutCreateWindow("我的第一个OpenGL程序。");
    glutDisplayFunc(&myDisplay);
    glutMainLoop();
    return 0;
}
