Two layered histidine

Click picture for the big 1024x768 version

This picture was generated from two seperate POV scripts. In SwissPDB, a histidine was displayed and exported as two separate POV scripts: one where the molecule was displayed as spacefill with type color coding and the other as ball & stick and CPK color coding. The two scenes were then manually merged. I substituted the texture of the spacefill bit with a transparent texture. The only thing you have to do when you want to make a texture transparant is to add a filter or transmission value to the texture color, e.g. (in case of filter):

color rgbf <1,1,0,0.95>

Instead of:

color rgb <1,1,0>

Valid f or t values are between 0 (opaque) and 1 (completely transparent). The textures of the ball & stick model are grained textures, although this is not apparent in the small version of the picture. Also added one more white pointlight.
