Full Screen Effect - Compilation

*** All 5 blogs containing sample shaders were compiled and moved into a resource: Sample Fullscreen Shaders ***

Hi all,
I am here by giving you the full screen radial blur effect using pixel shader 2.0

use this link given below to set full screen shaders to work.

http://www.garagegames.com/index.php?sec=mg&mod=resource&page=view&qid=9104

once setting full screen shader support is set

then create a new shaderdata in gameTSCtrl class and create a new shader using these hlsl data.


step 1: create a "Radialblur_vs.hlsl" file using default text editor and add the following code:

///////////////////////////////////////////////////////////////////////////////////////////////

struct VS_OUTPUT {
float4 Pos: POSITION;
float2 texCoord: TEXCOORD0;
};

VS_OUTPUT main(float4 Pos: POSITION){
VS_OUTPUT Out;

// Clean up inaccuracies
Pos.xy = sign(Pos.xy);

Out.Pos = float4(Pos.xy, 0, 1);
// Image-space
Out.texCoord.x = 0.5 * (1 + Pos.x);
Out.texCoord.y = 0.5 * (1 - Pos.y);

return Out;
}

//////////////////////////////////////////////////////////////////////////////////////////////


step 2: create a "Radialblur_ps2.hlsl" file using default text editor and add the code given below

///////////////////////////////////////////////////////////////////////////////////////////////


uniform sampler tex: register(s0);

static const float samples[10] =
{
-0.08,
-0.05,
-0.03,
-0.02,
-0.01,
0.01,
0.02,
0.03,
0.05,
0.08
};

float4 main(float2 texCoord: TEXCOORD0,
uniform float sampleDist,
uniform float sampleStrength
) : COLOR
{
//Vector from pixel to the center of the screen
float2 dir = 0.5 - texCoord;

//Distance from pixel to the center (distant pixels have stronger effect)
//float dist = distance( float2( 0.5, 0.5 ), texCoord );
float dist = sqrt( dir.x*dir.x + dir.y*dir.y );


//Now that we have dist, we can normlize vector
dir = normalize( dir );

//Save the color to be used later
float4 color = tex2D( tex, texCoord );

//Average the pixels going along the vector
float4 sum = color;
for (int i = 0; i < 10; i++)
{
sum += tex2D( tex, texCoord + dir * samples[i] * 1.0);
}
sum /= 11;

//Calculate amount of blur based on
//distance and a strength parameter
float t = dist * 2.2;
t = saturate( t );//We need 0 <= t <= 1

//Blend the original color with the averaged pixels
return lerp( color, sum, t );
}

////////////////////////////////////////////////////////////////////////////////////////


step 3: save these two files in shaders folder .

step 4: open shaders.cs file and added the folowing code in the last

new ShaderData(Radialblur)
{
DXVertexShaderFile = "shaders/Radialblur_vs.hlsl";
DXPixelShaderFile = "shaders/Radialblur_ps2.hlsl";
pixVersion = 2.0;
};

step 5: using this shader data you can now generate full screen radial blur effect like the other full screen shaders

nightvision,heatvision etc...
