This is the light modeling done by Priorblue [here](https://bitbucket.org/PriorBlue/love2d-light-and-shadow-engine),
only it has been largely refactored and edited to allow for scaling and proper translation.
## Features ##
* **[Preview (Video)](https://www.youtube.com/watch?v=6V5Dtsa6Nd4)**
* polygon shadow calculation [Preview](http://onepixelahead.de/love2d_polyshadow.png)
* circle shadow calculation
* image shadow calculation [Preview](http://onepixelahead.de/love2d_polyshadow18.png)
* shadow blur
* light color, range, smooth and glow [Preview](http://onepixelahead.de/love2d_polyshadow2.png)
* ambient light
* self shadowing on images with normal maps [Preview](http://onepixelahead.de/love2d_polyshadow_pixelshadow.png)
* dynamic glow effect on images and circle/poly objects [Preview](http://onepixelahead.de/love2d_polyshadow_glow.png) [Preview](http://onepixelahead.de/love2d_polyshadow15.gif)
* generate flat or gradient normal maps [Preview](http://onepixelahead.de/love2d_polyshadow7.png)
* convert height maps to normal maps [Preview](http://onepixelahead.de/love2d_polyshadow8.png)
* generate a normal map directly from the image (usually gives poor results)
* shadow color and alpha (glass) [Preview](http://onepixelahead.de/love2d_polyshadow9.png)
* directional light [Preview](http://onepixelahead.de/love2d_polyshadow12.png)
* refractions (moveable) [Preview](http://onepixelahead.de/love2d_polyshadow13.gif)
* chromatic aberration [Preview](http://onepixelahead.de/love2d_polyshadow16.gif)
* postshader with many included postshaders, plus easy to extend
