For “Advanced Computer Graphics”, a colleague of mine and I had to do a little shader project with FX Composer and CGFX.
We decided to create a shriveling apple material, which you can modify the age of. We used image based lighting for some nice diffuse and specular light, for the apple at a young age, reflections, and when getting older, some bump maps plus occlusion mapping. I ZBrushed the apple to get some nice maps, and so that I don’t have to paint them by hand. We also wanted to add some vertex displacement per vertex textures, but we somehow didn’t get them to work…
Anyway, here’s the result:
Shriveling apple shader - part 1
Shriveling apple shader - part 2
Shriveling apple shader - part 3
