相关疑难解决方法(0)

当使用缓冲区对象存储顶点数组时,我在openGL中遇到问题.当我运行代码时,会出现一个窗口,显示消息" 访问冲突读取位置0x000000000 ",当我将光标移动到glGenBuufers函数旁边的箭头时,我看到描述:这是当该线程从当前函数返回时执行的下一个语句.

码:

int frame=0;
void display();
void datasource();

 GLuint vbo;

void datasource()
{
    GLfloat vertex1[]={-1.000000 ,0.500000 ,-0.700000 ,0.500000 ,-1.000000 ,0.800000 ,-0.700000 ,0.800000 ,-0.400000 ,0.500000 ,-0.100000 ,0.500000 ,-0.400000 ,0.800000 ,-0.100000 ,0.200000 ,0.500000 ,0.500000 ,0.500000 ,0.200000 ,0.800000 ,0.500000,0.800000 ,0.800000 ,0.800000 ,0.500000 ,1.100000 ,0.500000 ,0.800000 ,0.800000 ,1.100000,0.800000  };

    glGenBuffers(1,&vbo);
    glBindBuffer(GL_ARRAY_BUFFER,vbo);
    glBufferData(GL_ARRAY_BUFFER,sizeof(vertex1),vertex1,GL_STATIC_DRAW);
}


void init(int arc,char **arch)
{
    glutInit(&arc,arch);
    glutInitWindowSize(800,800);
    glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
    glutCreateWindow("chess");
    glClearColor(0.0,0.0,0.0,0.0);
    glutDisplayFunc(display);
}

int main(int arc,char **arch)
{
    init(arc,arch);
    datasource();
    glutMainLoop();
    return 0;
} …
