植物果实的几何造型及可视化研究

Study on Geometry Model and Visualization of Plant Fruit

提出了一种基于曲面参数方程的植物果实的造型方法。该方法使用凹凸纹理处理方式对椭球面参数方程进行变形,模拟各种不同形状植物果实形状;利用正弦函数的变化规律对植物表面颜色纹理进行模拟。给出了仿真水果模型的实例,模型的可控参数较少,变换灵活,形象直观,易于构建虚拟植物果实的生长模型。

A new modeling method of the plant fruit based on parametric equation was introduced. By using the ellipsoid parametric equation and concave-convex texture, different parameter surface for plant fruit can be got through distortion processing. The color texture modeling which uses sine function was built. An example of building imitated fruits statuette was given, The controllable parameters of this model are few and the transformation is nimble. The growth model for hypothesized plant fruit is easy to construct.
