I need to rotate a image using the 3D api. To do this, I have build a texture
based on this image and associate it to a 3D object(a cube). Then I tryed
to make just one cube surface visible on the screen in order to simulate
a simple 2D image painting operation.
The problem is to set the proper appearence for the camera, in order to
optain a 1:1 scale, so the initial image should not suffer 3D api
transformations that could affect the qulity of the image. The image size is 128x128 pixels and I need to show it on a viewport with the same size.
Dose anyone knows how to set the proper camera parametes in order to be
able to see the initial image without transformations?
Any other solutions in rotating a image on the phone are welcome. Thanks!
