Android 上用于绘制应用程序的 OpenGL 或 Canvas
我开始编写一个手指画风格的应用程序（我已经看到了 Google Developer 资源上的教程）。该应用程序将具有以下内容：
1.）要在其上绘制的背景图像
2.）用手指绘制时，它不会绘制颜色，而是绘制纹理/图像，如 Photoshop 画笔。
我已经开始在 OpenGL 中实现，但遇到了在手指拖动期间创建许多四边形的问题。我想知道是否有人有一些指示可以引导我决定是否应该继续用 OpenGL 编写或废弃并转到 Canvas？像这样的应用程序有哪些优点和缺点以及限制。
非常感谢！
I am beginning to write a finger paint style application (I have seen the tutorial on the Google Developer resource). The application will have the following:
1.) A background image to paint on top of
2.) When drawing with finger, it will not draw colors, but a texture/image like a photoshop brush.
I have begun the implementation in OpenGL but am running into an issue with creating many quads during a finger drag. I was wondering if anyone had some pointers that can lead me to decide if I should continue writing in OpenGL or to scrap and go to Canvas? What are the advantages and disadvantages, as well as restrictions for an application like this.
Much appreciated!

我建议使用OpenGL。也许会更难，但将来当您需要应用程序提供更多功能时，这对您来说会更好。
I would suggest OpenGL. Maby harder but it will be much better for you in future when you will need more from your app.
我建议你们俩，但对于绘画，您应该使用 Canvas，但如果您还想编辑和添加效果，则需要 OpenGL。
I would suggest you both but for painting you should use Canvas but if you want also edit and add effects you need OpenGL.
