【摘要】 针对植物花朵开放过程的三维模拟,提出基于骨架驱动的花朵开放可视化方法。通过平面变形构建出描述花朵形状特征的数学模型,基于该模型生成花瓣骨架模型,通过驱动骨架模型发生形变,并根据变形后的花瓣骨架实现花瓣曲面变形;通过对圆柱参数方程进行位移扰动,模拟了花蕊的弯曲变形;最终,结合参数—L系统实现了百合花的动态开放模拟。实验结果表明,该方法可以灵活地控制花瓣曲面的弯曲变形,生成的花朵形象逼真,能较为真实地模拟花朵动态开放过程。更多还原

【Abstract】 In order to simulate 3D blooming flower,a visualization method based on skeleton driving flower blooming was proposed.Used plane deformation method,the mathematical model describing flower shape was built,based on which the flower skeleton was generated.Flower skeleton was deformed,thus the deformation of the flower mesh followed the deformation of the flower skeleton.Through position disturbance on Cylindrical parameter equation,deformation of stamans was simulated.Finally,used parametric L-System for simulating flower opening.The results showed that the proposed method could control the deformations of petal flexibly and generate realistic flower,thereby could create good animations of flower blooming.更多还原
