Cocos2DDynamicBokeh is a small test I did for a company interview. Project contains a DynamicBackgroundLayer node that generates Bokeh according to settings. All bokehs are batched into 2 draw calls for blurred and sharp variants to create fake depth of field effect while maintaining performance. Bokeh lifetime colour can be customize by modifying bokeh_gradient.png in the resources folder.
This project is created using cocos2d-x 3.5. Please place the cocos2d-x library in the root of the project and rename it to cocos2d when compile. Note that I've made a small change to cocos2d/cocos/renderer/CCQuadCommand.cpp to allow sprites with custom shaders and uniforms to be batched. Please replace the original CCQuadCommand to enable batching.
This project supports iOS and Android
