I don't know if you are referring to raytracing. Its the process of determining where shadows should be since the computer can't just 'know'. You need a decent phone though to be able to implement shadows and stuff - the graphic chip people (e.g. ATI) might probably handle some of that implementation, as soon as their chips are more comonly found in popular handsets.
