Barrel distortion effect for image (JavaFX)


I'm looking for some way to set background image with barrel distortion effect(FishEye/FOV) for node using JavaFX. I found algorithm with pixel manipulation, but I want to find some another way(some hack) for reach it. This effect will be use for create node background high definition image changing animation(animation wil be change factor(power/value/degree?)) of this effect.


Solution

  • I'd like to offer an alternative approach which is much more efficient (real-time capable). Any solution which is based on direct pixel manipulations is doomed to be very inefficient especially for a "high definition image".

    Instead I'd propose to use a TriangleMesh for this and use the image as its texture. You can then apply any kind of distortion you like by just manipulating the texture coordinates. This approach can be easily integrated into any 2D graphics via the JavaFX scene graph.

    I am actively using this concept for on-the-fly reprojection of raster map tiles, so I know it works.
