c++ opengl绘制正方体

1.源码实现

#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>

float angle = 0.0;

void init()
{
    glEnable(GL_DEPTH_TEST);
    glEnable(GL_MULTISAMPLE);
    glEnable(GL_LIGHTING);
    glEnable(GL_LIGHT0);

    glDepthFunc(GL_LEQUAL);
    glClearDepth(1.0f);

    GLfloat light_position[] = {1.0, -1.0, -0.5, 0.0};
    GLfloat light_ambient[] = {0.2, 0.2, 0.2, 1.0};
    GLfloat light_diffuse[] = {0.8, 0.8, 0.8, 1.0};

    glLightfv(GL_LIGHT0, GL_POSITION, light_position);
    glLightfv(GL_LIGHT0, GL_AMBIENT, light_ambient);
    glLightfv(GL_LIGHT0, GL_DIFFUSE, light_diffuse);

    glEnable(GL_COLOR_MATERIAL);

    glColorMaterial(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE);
}

void update(int value)
{
    angle += 2.0f;

    if(angle > 360)
    {
        angle -= 360;
    }

    glutPostRedisplay();

    glutTimerFunc(32, update, 0);
}

void display()
{
    glClearColor(0.0, 0.0, 0.0, 1.0);
    glClear(GL_COLOR_BUFFER_BIT);

    glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);

    glLoadIdentity();
    glRotatef(angle, 0.0f, 1.0f, 0.0f);
    glRotatef(angle, 0.0f, 0.0f, 1.0f);

    //glTranslatef(0.0f, 0.0f, -0.3f);

    glutSolidCube(0.8);

    glFlush();

    glutSwapBuffers();
}

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB|GLUT_DOUBLE|GLUT_DEPTH|GLUT_MULTISAMPLE);
    glutInitWindowSize(400, 400);

    glutCreateWindow("OpenGL Cube with Lighting");

    init();
    glutDisplayFunc(display);
    glutTimerFunc(16, update, 0);

    glutMainLoop();

    return 0;
}

2.编译源码

$ g++ -o example example.cpp -std=c++11 -lGL -lglut
