java - glRotatef 适用于多个对象

Question

基本上我想打开一扇门，我想到了使用 glRotatef。我的问题是它影响了在它之后绘制的每个对象。有谁知道如何阻止它？

门类

    public static void draw(Texture door) {  

    door.bind();
    if(Door_Test.state == "out" && d != 90){
        glRotatef(i, 0, 1, 0);
        i+=5;
    }
    glBegin(GL_QUADS);  
        glColor3f(1f, 1f, 1f);glTexCoord2f(0,0);glVertex3f(-2,3, -15);
        glColor3f(1f, 1f, 1f);glTexCoord2f(0,1);glVertex3f(-2,-3, -15);
        glColor3f(1f, 1f, 1f);glTexCoord2f(1,1);glVertex3f(2,-3, -15);
        glColor3f(1f, 1f, 1f);glTexCoord2f(1,0);glVertex3f(2,3, -15);
    glEnd();

}

常见的做法:

glPushMatrix();
glRotatef(/*...*/);
// Drawing commands here
glPopMatrix();
