| 摘 要： | 为了实现在三维虚拟环境中对农作物叶片的形态建模与精确控制,根据体图形学理论与八叉树的特点,提出了一种针对三维农作物叶片的八叉树体建模算法,由于叶片模型内部实体属性变化的不均匀性,并且三维叶片纹理、叶片旋转角度、颜色密度分布等复杂属性的变化不规则性,算法选取不规则的八叉树体元作为形态建模的主元素,进而更加充分的表示叶片内部的细节,整体形态建模效果表明,文中算法能够充分表达农作物叶片的内部属性,建模效果真实感强,并且易于控制。

| Abstract: | To realize the crop modeling and accurate control under 3D virtual environment,we offer a Octree modeling volume algorithm for the three-dimensional crop leaves according to Octree graphics theory.Considering the uneven varied properties of the leaf internal model,irregular features of the leaf texture,rotation and the color distribution,we choose the voxel as the main elements to build the model to express the more details of the leaf.The integral shape model effects show that the algorithm can precisely vividly depict the internal properties of the leaf and be easily controlled. |
