During his PhD, Raymondworked with Professor Steve Mann, who is widely recognized as the father of wearablecomputing. Together, they published and presented papers at leading conferences, includingthe SIGGRAPh and IEEE conferences, on real-time high-dynamic-range(Hdr)imaging,augmented reality, and digital eyeglasses, which involve high-performance computationusing CUda and visualization using openGLWilliam C. Y Lo is currently an MD-PhD candidate at Harvard Medical School.Heis pursuing his phd degree in the joint Harvard-MIT Medical Engineering and medicalPhysics program under the guidance of Professor Brett Bouma(and co-advisor professorBenjamin Vakoc) at Massachusetts General Hospital, who founded the niH-funded Centeror Biomedical OCT Research and Translation. He obtained his bachelor of applied sciencedegree in computer engineering and his msc degree in medical biophysics from the Universityof Toronto, where he worked with Professor Lothar Lilge and Professor Jonathan Rose onhigh-performance computing for photodynamic therapy planning using custom FPGAhardware and graphics processors with CUDAHe, along with J. Rose and L. Lilge, worked on Computational Acceleration for MedicalTreatment Planning: Monte Carlo simulation of light Therapies Accelerated using GPUsand FPGAs, VDM Verlag, 2010About the reviewersSamar Agrawal is a Python enthusiast with experience in developing large, scalable ERPsSaaS systems, and other cloud-based live operational systems. In his current organizationhe is responsible for the internal operational systems and automation systems. He lovedcomputers from an early age of 6, much before Windows 95 debuted. He values clean code,admires new cutting-edge technologies, and likes taking on complex problems. In his freetime, Samar can be found reading, trying new stuff, or exploring new places. He is currentlybased in Dubai. He holds a master's degree in advanced software engineering from theUniversity of sheffield, UK, and a bachelors degree in computer science and engineeringSebastian Eichelbaum was born in 1983 in Leipzig, Germany After school he studiedcomputer science and got his PhD in 2014. Since he got his first graphical calculator inschool, he has enjoyed conducting the pixel's dance programmatically. during his PhD,Sebastian involved himself in the practical use of modern computer graphics(Cg)in scientificvisualization. He fortified his knowledge of visualization and modern Cg technologies, boththeoretically and practically. as he collaborated with users, developers, and scientists fromdifferent practical and scientific fields, he gained a broad insight into visualization andits tremendous application specificness. The enormous demand for usable and specificvisualization tools made Sebastian start his own company. His visualization-centric softwaretechnologies, and knowledge help others better understand and analyze data of all sortsand sourcesOscar Ripolles received his degree in computer engineering in 2004 and his PhD in2009 from Universitat Jaume I in Castellon, Spain He was also a researcher at Universitede limoges, france, and Universidad politecnica de valencia, Spain. He is currently workingin neuroimaging at Neuroelectrics in Barcelona, Spain. His research interests includemultiresolution modeling, geometry optimization, hardware programming, and medicalimaging. Some of the books he has worked on are Open GL Development Cookbook andGLSL EsSentialsI would like to thank my other half, Anna, for her patience and supportduring the nights and weekends spent reviewing this bookQing Zhang is currently a Phd candidate in the department of computer Science at theUniversity of Kentucky, working with Professor Ruigang Yang. He obtained his bachelor ofscience degree in computer science from Tsinghua University in 2006 and his ms degree inmathematics from the University of Kentucky in 2010. His research interests span computergraphics and computer vision, in particular, human reconstruction and motion analysisHe was a research intern in the communication and collaboration systems group MicrosoftResearch(MSR)in 2008, and in the visual computing group microsoft Research Asia(MSRA)in 2010.
