3D Carousel in Android

Question

I am working on 3D Carousel for android.

I am using this code and the following is my current output.

enter image description here

I want to develop the following 3D shaped carousel.

enter image description here

I refered to the following questions which are already asked in SO.

The following is near to my requirement:

Using 3d Carousel project to create SPB Carousel style

From this I answer I put:

mCamera.rotateY(-((CarouselItem) child).getCurrentAngle());

inside getChildStaticTransformation() method of Carousel.java but I'm not getting a perfect result.

Please help me to solve it.

Can you upload the complete code to github or something similiar so I can have a look? — crazyPixel, Mar 27 '14 at 12:45
I am also looking for something similar to this.. Scroll Speed should also be a concern here, because the referred 3d carousel project has some blazing fast scrolling speed even on a tiny scroll. — Salman Khakwani, Apr 09 '14 at 19:29
I will take a look at this Question on this weekend, Insha Allah. — Salman Khakwani, Apr 09 '14 at 19:32
What are you trying to do? I get what you've done but not what youre trying to do, the question is not clear. — Exikle, May 09 '14 at 18:34
The rotation must depend on sinus of the angle, so multiply with `Math.sin(angle)` — skobaljic, May 10 '14 at 12:30
though this is iOS focused but the explanation for the math might help you: http://www.thinkandbuild.it/introduction-to-3d-drawing-in-core-animation-part-2/ — 2cupsOfTech, May 12 '14 at 02:20

You are using a function called Calculate3DPosition which calculates X, Y, Z positions from the angle and then those are used in a matrix.translate call.

What you need is actually much simpler - you just need to call matrix.rotate with the angle. It might look surprisingly easy when you've finished, but honestly, the only complexity in the 3D code you have copied is from attempting to keep everything facing the user instead of letting it rotate ...
