The　pure　geometry　based　rendering　technology　can　acquire　excellent　rendering　effect　but　will　affect　system　performance.　People　use　image　based　rendering　method　to　solve　this　problem　in　recent　years,　but　since　the　sampled　images　are　limited,　when　viewpoint　changes　continuously　in　rendering　process,　there　would　appear　leap　problem.　This　paper　proposes　a　kind　of　algorithm　that　introduces　geometric　information　to　traditional　image　based　rendering　approach　and　produces　new　image　for　adjacent　viewpoints.　It　achieves　smooth　transition　between　the　discrete　sampled　images,　solves　the　leap　problem　resulted　from　the　limited　sampled　images,　and　improves　system　performance　at　the　same　time.　©2010　IEEE.
