![]() The trouble is, the target mesh might be too low quality to map to appropriately and might have a strangely different topography as well. OR the face's vertices can be morphed dynamically by trying to map the topography person's face to the topography of the mesh, in theory resulting in extremely accurate representations of your expression. ![]() Either stuck between neutral and one of a set of other poses as above like if you don't have a face for say, being scared, the face could only partial angry and/or partial happy, hoping to approximate what you're doing. I fully understand why they don't do it though. It allows for subtle things like partial smiles, and it's typically easy to set up. You take another picture of it in that state, and then tell the 3D software to blend between the neutral face and that other face. Then change the positions of the vertices of the face a bit, pulling some this way or that until it looks like the character's smiling, or frowning, or angry. Basically you start with a neutral face, and then take a picture of it in that state. However it's easier to make a smiling face for example with shape deformations that looks exactly how you want. But, muscle deforms the skin over the unflexing parts, something bones don't do so well.Īdd enough bones and rig everything right, and you can approximate muscle movement. ![]() They just move or rotate in specific ranges (like your jaw is a hinge, your eyes rotate mostly in the same place in your head, etc.). For the uninitiated, bones more closely resemble the major underlying structure of the body or things that don't flex, so a jaw bone, "eye bones", and to an extent the tongue and ears all make more sense to have rigged bones. There's advantages and disadvantages to both.

![]() More recently, he has addressed molecular neurobiology, developing the in vivo nonsense suppression method for unnatural amino acid incorporation into proteins expressed in living cells. ![]() Dougherty's extensive research interests have taken him to many fronts, but he is perhaps best known for development of the cation-π interaction, a novel but potent noncovalent binding interaction. In 1979 he joined the faculty at the California Institute of Technology, where he is now George Grant Hoag Professor of Chemistry. Dougherty received a PhD from Princeton with Kurt Mislow, followed by a year of postdoctoral study with Jerome Berson at Yale. Dougherty California Institute of Technologyĭennis A. His primary research is in physical organic chemistry and bioorganic chemistry, with specific interests in catalysts for phosphoryl and glycosyl transfers, receptors for carbohydrates and enolates, single and multi-analyte sensors – the development of an electronic tongue, and synthesis of polymeric molecules that exhibit unique abiotic secondary structure. He is also the Associate Editor for the Journal of the American Chemical Society and serves on the editorial boards of Supramolecular Chemistry and the Journal of Supramolecular Chemistry. Sloan Research Fellow, the Searle Scholar, the Dreyfus Teacher-Scholar Award, and the Jean Holloway Award for Excellence in Teaching. He currently holds four patents and is the recipient of numerous awards and honors, including the Presidential Young Investigator, the Alfred P. After completing post-doctoral work with Ronald Breslow at Columbia University, he joined the faculty at the University of Texas at Austin, where he became a Full Professor in 1999.
