circleOfConfusionRadiusPixels()

float glsl::DepthOfField_glsl::circleOfConfusionRadiusPixels ( float  z, float  focusPlaneZ, float  screenFocusZ, float  nearBlurryPlaneZ, float  nearSharpPlaneZ, float  farBlurryPlaneZ, float  farSharpPlaneZ, float  nearScale, float  farScale, float  scale, const bool  chromaBlur, const int  model  )

inline

All the z values are negative numbers (in front of the camera).

Return value is a signed number where negative values mean that the point spread function is upside down and far from the camera and positive values are close.

If model == PHYSICAL the scale argument is computed as follows:

const float scale = (screenSize * 0.5f / tan(camera->fieldOfViewAngle() * 0.5f)) * camera->depthOfFieldSettings().lensRadius() / 
                (camera->depthOfFieldSettings().focusPlaneZ());
