Molecules 3D is an application for viewing three-dimensional renderings of molecules and manipulating them using your fingers. You can rotate the molecules by moving your finger across the display, zoom in or out by using two-finger pinch gestures, or pan the molecule by moving two fingers across the screen at once. These structures can be viewed in both ball-and-stick and spacefilling visualization modes.

New molecules can be downloaded from either the RCSB Protein Data Bank (http://www.rcsb.org/pdb), an international repository of biological molecules and their 3-D structures, or NCBI's PubChem (http://pubchem.ncbi.nlm.nih.gov), a public database of compounds. Molecules can be downloaded directly to your handheld device and stored there for later viewing.

Custom molecular structures can be downloaded to the application via iTunes file sharing, or through the use of custom URL formats. For more details, please visit our website.

FEATURES:

*Reenabled two finger planning of modelsin the rendering engine,allowing zooming and rotation from the center of the screen at all times.

*rendering engine provides realistic renderings of molucules,drawing true spheres and cylinders using ambiant occlusion shadowing.this engine works on newer ios devices,but older devices can still use the original renderer

*NCBI's pubchem has been added as a retrieval source for smaller molecules.

*Retina Display Support.

*rendering bonds for certain amino acid residues

*iTunes file sharing support for iPad and iphone

*A faster ,relevance-based keyboard searc for protien data bank.Molecules can continueally animate about their vertical axis.

*Custom molecule structures can be downloaded from user-specified locations.The molecules must be in PDB or Gzipped PDB formates and be located on a web server that the iPHone or iPod can access.the location of these files can be manually specified in the application or special molecules://URLs can be clicked on in mail or safari to activate the download.
