如何创建烟花在Android颗粒图形效果 [英] How to create fireworks particle graphics effect on android

问题描述

任何人有任何想法如何在画布上绘制制作烟花的效果？ 有一个在wireworks动态壁纸（免费的应用程序），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，多点移动，并留下足迹像爆炸的明星，并逐渐消失。我认为有某种运动​​模糊的每个点上移动，而我不知道如何创建。

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.

任何意见或链接到相关的例子是值得欢迎的。

Any ideas or links to relevant examples are welcome.

推荐答案

这是一个非常抽象的（和有趣的）问题，但过于复杂，详细回答。

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

你真正寻找的可能是一种改进的粒子系统。粒子系统基本上是一个引擎的粒子，其中包括物理引擎。

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.

不过，你应该专注于有这些：

However, what you should focus on are these:

• 内存池模式 - 因为你不希望在运行时分配对象有用的烟花
• 粒子系统教程 - 伟大的教程是专为Android
• 粒子系统 - 伟大的，但对于C ++

• 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++.

一旦你建立它（或者得到关于它的理解），你可以很容易地将其转换成画布系统，虽然的OpenGL 是preferable替代。

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.
