OpenGL model
Phong exponent called shininess. Several additions:
emmision; ambient, diffuse, specular light “intensities”
Setting material parameters (Kdiff,Kspec,Kamb,p)
GLfoat mat_diffuse[3], mat_spec[3], mat_amb[3]; GLfloat shininess;
... glMaterialfv(GL_FRONT,GL_DIFFUSE,mat_diffuse); glMaterialfv(GL_FRONT,GL_SPECULAR,mat_spec);glMaterialfv(GL_FRONT, GL_AMBIENT,mat_amb); glMaterialf(GL_FRONT, GL_SHININESS,shininess);
