Quadrics and Translucency

Hi,

how do I make my quadrics translucent? I’m using glutSolidSphere to draw
my quadrics, and I color them with glColor3f. I tried to change glColor3f to
glColor4f and specify alpha-value but it didn’t have any effect. My quadrics’
materials are:


private float no_mat[] = {0.0f,0.0f,0.0f,1.0f}; // Materials

private float mat_diffuse[] = {0.1f,0.5f,0.8f,1.0f};

private float mat_specular[] = {1.0f,1.0f,1.0f,1.0f}; 

private float no_shininess[] = {3.0f};

glMaterialfv (GL.GL_FRONT, GL.GL_AMBIENT, no_mat);

gl.glMaterialfv (GL.GL_FRONT, GL.GL_DIFFUSE, mat_diffuse);

gl.glMaterialfv (GL.GL_FRONT, GL.GL_SPECULAR, no_mat);

gl.glMaterialfv (GL.GL_FRONT, GL.GL_SHININESS, no_shininess);

gl.glMaterialfv (GL.GL_FRONT, GL.GL_EMISSION, no_mat);
