How to change the light position?????

[berry3238]

Hi,
I want to change the light position but I don't know how to do that? I know that you have to use GL_POSITION or something
like that but I don't know how to change it properly. Also do you know how to change the color of
the light to make it with red,blue, or green shades.

This is how I'm doing it


// Set up the values (these variables may be global)
GLfloat global_ambient[4]= {0.2, 0.2, 0.2, 1.0};
GLfloat light0pos[4] = {0.0, 0.0, 0.0, 1.0};
GLfloat light0ambient[4] = {0.25, 0.25, 0.25, 1.0};
GLfloat light0diffuse[4] = {0.55, 0.55, 0.55, 1.0};
GLfloat light0specular[4]= {0.15, 0.15, 0.15, 1.0};

// Call this in OnCreate()of your window/view or any intitalization fn.
glEnable(GL_LIGHTING);
glEnable(GL_LIGHT0);

glLightModelfv(GL_LIGHT_MODEL_AMBIENT, global_ambient);
glLightModeli(GL_LIGHT_MODEL_TWO_SIDE , 0);
glLightfv(GL_LIGHT0, GL_AMBIENT, light0ambient);
glLightfv(GL_LIGHT0, GL_DIFFUSE, light0diffuse);
glLightfv(GL_LIGHT0, GL_SPECULAR, light0specular);
glLightfv(GL_LIGHT0, GL_POSITION, light0pos);




There are other ways of doing this, but this way seems to be convenient
