Once you’ve made a call to glMaterialfv(…) is there a way to return to the state before this call was made?
I’ve written a program for exploring what an object (a sphere) will look like as I change the RGBA reflection coeffecients. Code in question looks something like this:
if (mat_amb_cb == 1) glMaterialfv(GL_FRONT, GL_AMBIENT, matAmb);
if (mat_dif_cb == 1) glMaterialfv(GL_FRONT, GL_DIFFUSE, matDif);
The if statments are not excuted till I check the appropriate check box. Once they are unchecked, and those lines are not longer executed in the rendering routine the sphere will still retain those material properties.
