An　interactive　virtual　tree　structure　editing　method　is　proposed　to　address　the　irreversible　tree　pruning　process　challenge　in　the　field　management.　Parametric　3D　tree　model　was　built,　and　interactive　stem　picking　method　based　on　Back-Buffer　is　proposed　by　integrating　the　tree　hierarchical　topology.　OpenGL　rendering　technique　was　used　to　implement　interactive　stem　editing　functions,　such　as　branches　pruning,　shoot　sections　pruning,　branch　length　or　radius　adjustment.　Using　the　canopy　type　found　in　common　ornamental　and　afforestation　trees　as　the　constraint　mode,　comprehensive　3D　tree　morphing　can　be　achieved　rapidly　and　intuitively.　This　method　not　only　improves　the　parameter-based　3D　tree　modeling　system,　but　also　provides　a　digital,　visual,　intelligent　way　to　plant　type　design　and　pruning　for　virtual　tree　planting　and　management.
