Directions for Framewerk with engine version 2.8:

 

Field filter_radialblur:TShader
Field filter_radialmaskedblur:TShader

Field radialblur_enabled:Int = False
Field radialblur_blur:Float = 0.0070

Field radialmaskedblur_enabled:Int = False
Field radialmaskedblur_mask:TTexture
Field radialmaskedblur_opacity:Float = 1.0
Field radialmaskedblur_blur:Float = 0.0075

 

Within the Draw method:

 

If radialblur_enabled
DrawEffectRadialBlur(postbuffer[1-cb].colorbuffer[0])
EndIf

If radialmaskedblur_enabled
DrawEffectRadialMaskedBlur(postbuffer[1-cb].colorbuffer[0])
EndIf

 

 

The methods:

 

Method DrawEffectRadialBlur(colortexture:TTexture)
	If Not filter_radialblur filter_radialblur = LoadShader("abstract::radialblur.vert","abstract::radialmaskedblur.frag")

SetShader(filter_radialblur)
SetShaderFloat(filter_radialblur, "blur", radialblur_blur)

colortexture.bind(0)
DrawFlippedImage(colortexture)
EndMethod

Method DrawEffectRadialMaskedBlur(colortexture:TTexture)
	If Not filter_radialmaskedblur filter_radialmaskedblur = LoadShader("abstract::radialmaskedblur.vert","abstract::radialmaskedblur.frag")
	If Not radialmaskedblur_mask radialmaskedblur_mask = LoadTexture("abstract::radialmask_full.dds")

SetShader(filter_radialmaskedblur)
SetShaderFloat(filter_radialmaskedblur, "opacity", radialmaskedblur_opacity)
SetShaderFloat(filter_radialmaskedblur, "blur", radialmaskedblur_blur)

colortexture.bind(0)
radialmaskedblur_mask.bind(1)
DrawFlippedImage(colortexture)
EndMethod

 

 

 

This effect doesn't play nicely while submerged, so it's best to disable the effect when you're submerged, and turn it back on (if it was on when going submerged) when you're no longer submerged.

For the radialmaskedblur you can change the radialmaskedblur_mask texture to use different effects. The zip file provides six different textures that will provide the blur within specific locations. Feel free to play around with them and/or make your own.

If anyone makes any improvements to the shader or improvements with the shader in combination with framewerk, please let me know.

Excellent, Thanks EC most generous of you, much appreciated.

Not a problem them. This effect is seen in most games, such as Crysis and Far Cry 2. Can be used for multiple types of situations.

I most definately have a use for this, I was following your shader work on the old forum and on your Blog, all very impressive.

Thanks man I'll be releasing more shaders once I finish them. I have a lot more work in the post-processing area just for my own project but I'll be sharing most of them. I think the next shader I'll be working on is water/rain screen splats.

Wasn't hnphan doing some work on raindrops .. splats .. water things ? I seem to recall a purple based screenie with oil drums but can't remember much more than that.

[Paul Thomas]

Yeah. Several months ago I asked if I could get the source to it but he said he was too busy at the time. I then continued my conversion from HLSL to GLSL learning curve, lol.

lol ..

 

 

I found the thread ... I was right purple and oildrums certainly an effect worth having. I look forward to your work in this area.

[Paul Thomas]

Yeah, I think it'll be fun, and I plan to animate the rain/blood. We'll see how it goes but I think it'll be a fun project.

thanks for generously sharing your work on these, Eternal Crisis.

The code to his shaders for the chromatic dispersion is included in the HNPHAN folder in every single Leadwerks distro.
