摘要
提出了一种基于真实数据并保持原始参数不变的植物叶柄器官建模方法。首先通过叶柄长度、叶柄半径参数建立柄的三维模型,并加入表面绒毛的模拟以增强真实感;为了丰富模型的形态,提出了基于交互的形态调整方法,该方法以关节链及逆向运动学为基础,辅以误差补偿算法,使交互调整过程中模型的原始参数(长度、半径)保持不变。试验结果表明,该方法可以快速、灵活地构建出叶柄器官的三维形态,具有较好的真实感效果,且变形过程中参数的变化很小。
A petiole modeling method based on keeping original data constant technology was presented.The length and radius parameters were set to establish a 3-D model,and the surface hair simulation was used to enhance the sense of reality.In order to produce 3-D models with multiple shapes,an interactive method was proposed to adjust the model shape based on joint chain,IK method and error compensation algorithm which made the method could keep the original parameters（length and radius） constant.The results showed that the method could build 3-D petiole model quickly and flexibly,and had good realistic effect.More importantly,the variation of parameters was very small in the interactive deformation process.
