如何在android上创建烟花粒子图形效果 [英] How to create fireworks particle graphics effect on android

问题描述

有人知道如何通过在画布上绘画来制作烟花效果吗?在wireworks动态壁纸(免费应用程序)中有一个很好的例子.

Anybody has any idea how to make a fireworks effect by drawing on canvas? There is one nice example in wireworks live wallpaper (free app).

在那里，许多点像爆炸一样在恒星中移动并留下痕迹，然后逐渐消失.我认为每个点移动都有某种运动​​模糊，我不知道如何创建.

There, many points move and leave trails in a star like explosion and gradually disappear. I think that there is some kind of motion blur on each point moving, which I am not sure how to create.

欢迎提供任何想法或相关示例的链接.

Any ideas or links to relevant examples are welcome.

推荐答案

这是一个非常抽象(也很有趣)的问题，但太复杂了，无法详细回答.

That's a very abstract (and interesting) question but far too complex to answer in details.

您真正要寻找的可能是一种经过修改的粒子系统.粒子系统基本上是包含物理引擎的粒子引擎.

What you're really looking for is probably a sort of a modified particle system. A particle system is basically an engine for particles that includes a physics engine.

但是，您应该关注以下几点:

However, what you should focus on are these:

• 内存池模式 - 对烟花很有用，因为你不想在运行时分配对象.
• 粒子系统教程 - 很棒，而且教程专门针对 Android.
• 粒子系统 - 很棒，但对于 C++ 而言.

• Memory Pool pattern - useful for fireworks since you don't want to allocate objects during runtime.
• Particle system tutorial - great and the tutorial is specifically for Android.
• Particle system - great, but for C++.

一旦您构建了它(或了解了它)，您就可以轻松地将其转换为 Canvas 系统，尽管 OpenGL 是更好的选择.

Once you built it (or gotten an understanding about it) you can easily convert it to the Canvas system, although OpenGL is the preferable alternative.
