Question

I’m attempting to make a chromed cube in GLUT / OpenGL and I’m not sure exactly how to do it.

I looked up a ‘Materials Table’ in a textbook which showed ‘Chrome’ as being: Ambient: (0.25, 0.25, 0.25), Diffuse: (0.4, 0.4, 0.4), and Specular: (0.774597,0.774597,0.774597).

My question is, how do I create a simple cube and apply this material/texture to it in Glut/OpenGL?

Do I use ‘glutSolidCube()’? If so, how do I then apply the chrome texture to it?

Can any GLUT/OpenGL people point me in the right direction?

Answer 1

This should be as simple as calling glMaterialfv() before glutSolidCube().

I haven’t done OpenGL since school, but here’s some display loop code from an old project that used a sphere that should get you on the right track:

_Ambient[CHROME][0] = 0.25f; _Ambient[CHROME][1] = 0.25f; _Ambient[CHROME][2] = 0.25f; _Ambient[CHROME][3] = 1.0f; _Diffuse[CHROME][0] = 0.4f; _Diffuse[CHROME][1] = 0.4f; _Diffuse[CHROME][2] = 0.4f; _Diffuse[CHROME][3] = 1.0f; _Specular[CHROME][0] = 0.774597f; _Specular[CHROME][1] = 0.774597f; _Specular[CHROME][2] = 0.774597f; _Specular[CHROME][3] = 1.0f; _Shininess[CHROME] = 76.8f;   void Display() {   glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);    glPushMatrix();     glMaterialfv(GL_FRONT_AND_BACK, GL_AMBIENT, _Ambient[CHROME]);     glMaterialfv(GL_FRONT_AND_BACK, GL_DIFFUSE, _Diffuse[CHROME]);     glMaterialfv(GL_FRONT_AND_BACK, GL_SPECULAR, _Specular[CHROME]);     glMaterialf(GL_FRONT_AND_BACK, GL_SHININESS, _Shininess[CHROME]);     // Translations...     glutSolidSphere(_Radius, _Slices, _Stacks);   glPopMatrix();    glFlush();    glutSwapBuffers(); }
