OpenGL：简单的glut立方体不亮
嗨，我正在尝试研究opengl和glut中的灯光，但是我很早就遇到了问题。我有以下代码，可以通过自定义相机设置在自定义位置制作发光立方体：
void testApp::draw(){
static float amb[] = {0.4, 0.4, 0.4, 0.0};
static float dif[] = {1.0, 1.0, 1.0, 0.0};
float light_diffuse[] = {1.0, 0.0, 1.0, 1.0};
float light_position[] = {-1.0, 1.0, 1.0, 0.0}; // i tried a lot of positions here!
// set camera
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
gluLookAt(0, 200, 1200, 0,0,0, 0,1,0);
// set lights
glLightfv(GL_LIGHT0, GL_DIFFUSE, light_diffuse);
glLightfv(GL_LIGHT0, GL_POSITION, light_position);
glEnable(GL_LIGHT0);
glEnable(GL_LIGHT1);
glEnable(GL_LIGHTING);
glMaterialfv(GL_FRONT, GL_AMBIENT, amb);
glMaterialfv(GL_FRONT, GL_DIFFUSE, dif);
// draw scene
ofScale(50, 50, 50);
glPushMatrix();
glutSolidCube(2);
// close everything
glPopMatrix();
glDisable(GL_LIGHT0);
glDisable(GL_LIGHT1);
glDisable(GL_LIGHTING); }

float light_diffuse[] = {100.0, 0.0, 100.0, 100.0}; float light_position[] = {-100.0, 100.0, 1.0, 0.0};
