// Depth of field effect.

|
// Depth of field effect. Original from keijiro san's implement, slightly change to fit my engine.
|
|
// https://github.com/keijiro/KinoBokeh
|
|
|
|
|
|
// NOTE: keijiro san blur Near and far together, sometimes looks bad. eg. front blur's bleeding is small, and sometimes the composite looks no good.
|
|
// Other engine like unreal engine/CryEngine, they pre-multiply Coc, and blur near far with different RT, and they also Tile Coc to find Maximum/Minimum gay.
|
|
// So the final near blur will bleeding to src image, which help to natural transition.
|
|
//
|
|
// BTW, it still is a good dof for current engine, dof only open when miku dance, we always focus miku chan, so near blur is un-importance.
