Question

glRoatef功能不起作用我不知道为什么......

下面的代码这是使用SDL在主循环中调用的显示功能：

void display(){

glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT);
glLoadIdentity();

GLfloat ambientColor[] = {0.2f, 0.2f, 0.2f, 1.0f};
glLightModelfv(GL_LIGHT_MODEL_AMBIENT, ambientColor);

Control(0.2,0.2,mousein);
drawSkybox(50.0);
UpdateCamera();

renderLine(0,0,0,100,0,0,0,0,255);
renderLine(0,0,0,0,100,0,0,255,0);
renderLine(0,0,0,0,0,100,255,0,0);

我忘了补充说这是不行的：

glPushMatrix();
glRotatef(1,0,0,360);
glScalef(0.05,0.05,0.05);
glCallList(ship);
glPopMatrix();

for(int i = 0;i<planets.size();i++){
glPushMatrix();
planets[i].render();
glPopMatrix();
}
       }

在控制功能中，这些旋转有效。

glRotatef（-camPitch，1.0,0.0,0.0）; glRotatef（-camYaw，0.0,1.0,0.0）;

更新相机也会翻译场景glTranslatef（-camX，-camY，-camZ）;

同样在init功能中，这就是我设置相机的方式

glMatrixMode(GL_PROJECTION);
    glLoadIdentity();
    gluPerspective(45,640.0/480.0,0.1,500.0);
    glMatrixMode(GL_MODELVIEW);

Answer 1

~~void glRotatef（GLfloat x，GLfloat y，GLfloat z，GLfloat angle）~~

void glRotatef（GLfloat angle，GLfloat x，GLfloat y，GLfloat z）;

OpenGL：glRotatef不工作？
