Three-dimensionalprinting

Inthefieldofprinting,three-dimensionalprinting,whichreproducesthree-dimensionalimagesofobjectsinthree-dimensionalspace,hasbecomeanimportantcontentinthespecialprintingindustry.Theprincipleofthree-dimensionalprintingistosimulatethedistancebetweenhumaneyesandshootfromdifferentangles.Theleftandrightpixelsarerecordedonthephotosensitivematerial.Whenviewing,thelefteyeseestheleftpixelandtherighteyeseestherightpixel.TheprintedmatterproducedaccordingtothisprincipleiscalledForthree-dimensionalprinting.

Three-dimensionalprintinghasthefollowingcharacteristics:(1)Itcanrealisticallyreproduceobjectsandhasastrongthree-dimensionalfeeling.Theproductimageisclear,richinlayers,vividinimage,anddeepinartisticconception;

Actually,stereovisionisthestereoinformationformedbycombiningthesecomplexfactorsinthevisualprocess.Intermsofphysiologicalfactors,thereareparallax(binocularparallaxandmonocularmotionparallax),convergence,andaccommodation.Specifically,binocularparallaxisthefundamentalfactorforpeopletoobtainstereovision.Thatis,indailylife,whenpeopleobserveanobject,duetotheangleofviewbetweenthetwoeyesandotherreasons,theimageoftheobjectseenbytheleftandrighteyeswillbedifferent,thatis,Parallax,itgivespeopleasenseofthree-dimensionality.
