glRoatef 函数不起作用我不知道为什么......
下面的代码这是在使用 SDL 的主循环中调用的显示函数:
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);
我忘了补充一点,这是不工作的一点:
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,这些旋转起作用。
glRotatef(-camPitch,1.0,0.0,0.0); glRotatef(-camYaw,0.0,1.0,0.0);
更新相机也会平移场景 glTranslatef(-camX,-camY,-camZ);
同样在 init 函数中,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);
