Vignette PostFx - Shader
by J0linar · 10/25/2013 (4:24 pm) · 7 comments
Hi all
so instead of keeping it where others cant get @ it
am releasing thsi as a Resource
it might not look like much but it gives/ at least sometimes a nicer touch to your games
Special Note:
This shader is based on Andy J.Edmonds - postFx library Resource
www.garagegames.com/community/resources/view/21224
Howto:
go to your game/shaders/common/postFx folder
create a folder called vignette
there create a textfile
name it VignetteP.hlsl
open the file
and insert
next step
go to the game/core/scripts/client/postFx folder
and create a new textfile
name it vignette.cs
and insert the following
If the T3D-OpenSource-Commitee should see it worthy enough
it can add it to T3D MIT
anyways hope someone finds it useful

how is activate this?(all is integrated,but not seen effect)
#4
In the function
This enables Vignette from the start.

In game/scripts/client/serverConnection.cdIn the function
GameConnection::onConnectionAccepted(%this) //Add this line VignettePostEffect.enable(); }
This enables Vignette from the start.

here it is fixed....
VignetteP.hlsl
and vignette.cs
only diff is where i put my VignetteP.hlsl... for me it was shaders/common/postFx/Library/VignetteP.hlsl

outstanding, but your code has " instead of the regular ".....here it is fixed....
VignetteP.hlsl
#include "shaders/common/postFx/postFx.hlsl"
#include "shadergen:/autogenConditioners.h"
uniform sampler2D backBuffer : register(S0);
uniform float radiusX;

{
float4 base = tex2D(backBuffer, IN.uv0);
float dist = distance(IN.uv0, float2(0.5,0.5)) * 0.7 ;
base.rgb *= smoothstep(radiusX, radiusY, dist);
return base;
}and vignette.cs
// Vignette PostFx
$VignettePostEffect::RadiusX = 0.6;

anyways am glad ppl find use for this and a tip by combining the vignette with color correction - you can achieve pretty nice results.

Ye sry, no idea why markup lite converted it to "anyways am glad ppl find use for this and a tip by combining the vignette with color correction - you can achieve pretty nice results.
