Warp transformation library

  • Hi,

    I wanted to project a slideshow of images on curve screen. Have anyone came across Qt library that allows me to easily manipulate/warp transform the image by using its original points to its shifted points? Please see below illustration.

    I don't know of any but it should be quite straightforward to implement. Basically you map coordinates from one space to another based on a parametric transformation (a matrix) and then interpolate where the pixels are closer/farther from one another.

    This should be helpful as an introduction.

    Another thing (and I'd say a proffered method) is if you can find an external library and interface Qt with it.

    Kind regards.
