Java 2D 着色/填充
我已经从贝塞尔曲线（下面的屏幕截图）创建了一个“斑点”，现在想以伪 3D 的方式对其进行着色，所有“左”边缘上的阴影较暗，所有“右”边缘上的阴影较亮，也许表面上还有纯白色的“光点”。例如：我对如何实现此视频中使用的阴影感兴趣。
- 谁能推荐一个好方法来实现这一目标？我猜测标准 Graphics2D.fill 和 setPaint 方法可能不够复杂。
- 另外，有人可以推荐一些好的资源（最好是免费的/在线的）来了解更多这方面的知识吗？

一些附加信息：为了实现下面的平面填充效果，我创建了一个Area对象并添加了单独的Ellipse2DShape使用add(new Area(ellipse))添加到它，然后最后添加中心多边形区域以避免在中间留下空白。
I have created a "blob" from Bezier curves (screenshot below) and would now like to shade it in such a way that it appears pseudo-3D, with darker shading on all "left" edges and lighter on all "right" edges, and perhaps pure white "light spots" on the surface itself. For example: I'd be interested in how to achieve the shading used in this video.
- Can anyone recommend a good way to achieve this? I am guessing that standard Graphics2D.fill and setPaint methods may not be sophisticated enough.
- Also, can anyone recommend some good resources (preferrably free / online) for learning more on this?
EDIT
Some additional information: To achieve the flat fill effect below I'm creating an Area object and am adding the individual Ellipse2D Shapes to it using add(new Area(ellipse)) and then finally adding the central polygon area to avoid leaving a white space in the middle.

iPhone 应用程序可以访问 OpenGL -ES 允许在着色和渲染方面有很大的自由度，基本上是带有发光照明的彩色等值面。 Java2d 肯定不够复杂，除非你愿意为它编写一个完整的软件 3d 库。
混合 2d 和 3d 也是可能的。
The IPhone apps have access to OpenGL-ES which allows significant latitude in shading and rendering what is basically a coloured iso-surface with emissive lighting. Java2d will definitely not be sophisticated enough unless you are willing to write a whole software 3d library for it.
Mixing 2d and 3d is also possible.
我在此 运动模型以获得伪 3D 效果。我相信有更通用的实现在Java 6中。
I used a custom RadialGradientPaint in this kineic model to get a pseudo-3D effect. I believe a more general implementation is available in Java 6.
