Question

I want to achieve a nice 3D page curl animation in Android. I read some articles and found that nice effect can be achieved by OpenGL-ES so I started to learn OpenGL-ES (I did some of tutorials of OpenGL-ES and am still continuing) but I found it too complex for me to achieve this functionality. Also I got some examples which are available on StackOverflow and on the net, they work but I am not able to understand it, can someone guide me to achieve this functionality?

Answer 1

Based on the question comments I have an answer to this question.

YES, you can do that with OpenGL, BUT you need a deep understanding of math and graphics. This is a lot to learn, this will cost you at least a couple of weeks and it’s definitely a hard path to go if you do it only because of this single animation (all of this applies if you don’t take code which you probably won’t understand and another human being put his whole effort into).

Nevertheless there might a ready to use implementation but unfortunately I can’t present you one because I don’t know if there’s any out there.

Update

You callenged me, so I was eger to know whether there is something out there (because I saw that before and couldn’t believe that there isn’t a project out there which already does that for you).

And actually I found this question which seems to address the very same issue. And yes, there’s someone who published his results here. And I have to admit: I looks awesome. It’s also a pure java implementation.

But still: Having some background knowledge about OpenGL would enhance your whole attitude as developer. I’m not saying it’s a must because not every one will succeed in OpenGL programming because it’s quite hard to learn and implies a lot of math. But I think it’s worth it because you will gain some deep understanding of current and all future graphical interfaces.
