Abstract：

A　rapid　virtual　tree　pruning　method　based　on　color　encoding　is　proposed　to　address　the　challenge　of　interactive　pruning　operations　in　3D　space.　The　requirements　and　difficulties　are　analyzed.　Based　on　ParaTree-a　parameter-based　3D　tree　modeling　system,　a　rapid　3D　primitive　picking　method　for　a　large　collection　of　metadata　is　proposed.　It　encodes　a　3D　tree　model　with　32-bits　RGBA　colors,　and　fulfills　interactive　stem　pruning　by　leveraging　the　off-screen　buffers　of　GPU　and　the　color　encoding.　Experimental　results　showed　that　our　method　is　accurate,　fast,　general-purposed,　and　is　compatible　with　various　tree　modeling　approaches.　The　proposed　method　provides　a　new　way　to　digital　type　design　and　pruning　for　virtual　tree　planting　and　management.
