how to colour /filling up a 3d plot with designated colours

Hi

Just wonder how can I colour/shade a plot as shown in this link. (In this link, it is a heart shape)

I would like to have the glare, shadow effect as in the figure shown instead of filling the whole shape with just one colour

Thanks
