如何在opengl中隨機創建1000個對象（例如立方體，球體，圓柱體）？

Question

我創建了一個房間。這是我的房間的代碼：

void room(){ 
    glColor3f(1.0, 1.0 ,0.0); 
    glNormal3f(0,1,0); 
    glVertex3f(500 ,-3.0, 500); 
    glVertex3f(-500 ,-3.0, 500); 
    glVertex3f(-500 ,-3.0,-500); 
    glVertex3f(500 ,-3.0,-500); 
} 

現在我想隨機生成很多對象，如立方體，球體，圓柱體。你能幫我嗎？怎麼做？

質量問題需要質量響應

for (int i = 0; i < 50000; i++) { 
    glPushMatrix(); 
    glTranslatef(-500 + rand() % 1000, 7 + rand() % 100, -500 + rand() % 1000); 
    glutSolidTeapot(10); 
    glPopMatrix(); 
} 

或者還不如不過剩

GLUquadric* q = gluNewQuadric(); 
for (int i = 0; i < 50000; i++) { 
    glPushMatrix(); 
    glTranslatef(-500 + rand() % 1000, 7 + rand() % 100, -500 + rand() % 1000); 
    gluSphere(q, 10, 10, 10); 
    glPopMatrix(); 
} 
gluDeleteQuadric(q);
