Lesson 4: Lighting

 

main.cpp

 glEnable(GL_LIGHTING); //Enable lighting
 //조명 2개 활성화
 glEnable(GL_LIGHT0); //Enable light #0
 glEnable(GL_LIGHT1); //Enable light #1
 glEnable(GL_NORMALIZE); //Automatically normalize normals

 

 //Add ambient light
 GLfloat ambientColor[] = {0.2f, 0.2f, 0.2f, 1.0f}; //Color (0.2, 0.2, 0.2)
 glLightModelfv(GL_LIGHT_MODEL_AMBIENT, ambientColor); //은은한 라이트로 설정
 
 //Add positioned light
 GLfloat lightColor0[] = {0.5f, 0.5f, 0.5f, 1.0f}; //Color (0.5, 0.5, 0.5)
 GLfloat lightPos0[] = {4.0f, 0.0f, 8.0f, 1.0f}; //Positioned at (4, 0, 8)
 glLightfv(GL_LIGHT0, GL_DIFFUSE, lightColor0); //GL_LIGHT0의 짙은 정도와 칼라 설정
 glLightfv(GL_LIGHT0, GL_POSITION, lightPos0); //GL_LIGHT0의 위치 선정
