如何在C++中使用glutBitmapString()将文本绘制到屏幕上？

sudo apt-get install freeglut3-dev

#include <GL/glut.h>
#include <GL/freeglut.h>
#include<iostream>

void display();
void renderBitmapString(float x, float y, const char* string);

int main(int argc, char** argv) {
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
    glutInitWindowSize(800, 600);
    glutInitWindowPosition(100, 100);
    glutCreateWindow("Bitmap String");
    glutDisplayFunc(display);
    glutMainLoop();
}

void display() {
    glClearColor(0.0, 0.0, 0.0, 1.0);
    glClear(GL_COLOR_BUFFER_BIT);
    glColor3f(1.0, 1.0, 1.0);
    renderBitmapString(200, 200, "Hello, World!");
    glFlush();
}

void renderBitmapString(float x, float y, const char* string) {
    glRasterPos2f(x, y);
    for (int i = 0; string[i] != '\0'; i++) {
        glutBitmapCharacter(GLUT_BITMAP_HELVETICA_18, string[i]);
    }
}

g++ main.cpp -o main -lglut -lGLU -lGL
./main
