Background:　To　simulate　the　anisotropic　solid　texture　in　3D　space,　a　kind　of　solid　texture　synthesis　algorithm　based　on　the　samples　that　extends　the　2D　texture　patch　pasting　technology　to　3D　hepatic　artery　solids　is　proposed.　Methods:　Firstly,　the　surface　model　is　tetrahedral　with　Delaunay　tetrahedral　method.　Secondly,　the　color　attribute　is　used　to　generate　the　depth　field　and　the　depth　field　gradient　direction　is　the　first　vector　field,　then　the　second　vector　field　is　defined　by　the　arrow　icon.　The　third　vector　is　the　product　of　the　first　two　vectors.　Finally,　the　vector　field　of　the　whole　model　is　generated　by　Laplasse　interpolation.　Results　&　Conclusion:　The　experimental　results　showed　that　the　proposed　method　can　be　used　to　synthesize　the　desired　texture　effect　on　any　three-dimensional　region,　and　it　can　simulate　the　internal　structure　of　the　hepatic　artery　and　realize　the　real-time　visualization　of　the　cutting.　©　2018　Bentham　Science　Publishers.
