Dolphin, the GameCube and Wii emulator - Forums

Hey,

I modified the bad_bloom shader because while I loved what it did to the colors I wasn't a huge fan of the aggressive blurring. I spent around an hour tinkering with the shader and I settled with only a couple minor changes:

* 7% increased brightness
* 33% reduced blur/distortion

no shader vs bad_bloom (default shader)

no shader vs less_bloom (modified shader)

I've also attached a less_bloom_no_blur that has the increased bloom brightness but almost entirely eliminates the blur/distortion. It's a nice alternative if you like a crisp looking UI but still want the bright colors.

Installation instructions:

1. Download the .txt files and save them to the Shaders folder in your Dolphin folder (Dolphin-x64\Sys\Shaders)
2. Rename the .txt file extension to .glsl
3. Open Dolphin and select the shader in Graphics > Enhancements (tab) > Post-Processing Effect (drop-down menu)

If you don't rename the .txt files to .glsl they won't show up in the drop-down menu.

Thanks for this. less_bloom_no_blur looks especially good to me.

perdón no hablo inglés xD
Creo que he reparado el sombreador a lo que queríamos :v

Google Translation: sorry I don't speak English xD
I think I have fixed the shader to what we wanted: v

Code:
float2 position;

float4 bloom(float4 v, float2 radius);

float4 sum(float2 v, float2 radius);

float4 sum(float2 v, float2 radius){

 float4 powSample = SampleLocation(position + v * radius);

 return max((powSample-0.8)*5,float4(0,0,0,0));

}

float4 bloom(float4 v, float2 radius){

 v += sum(float2(0.4, 0.9), radius);

 v += sum(float2(0.7, 0.7), radius);

 v += sum(float2(0.9, 0.4), radius);

 v += sum(float2(1, 0), radius);

 v += sum(float2(0.9, -0.4), radius);

 v += sum(float2(0.7, -0.7), radius);

 v += sum(float2(0.4, -0.9), radius);

 v += sum(float2(0, -1), radius);

 v += sum(float2(-0.4, -0.9), radius);

 v += sum(float2(-0.7, -0.7), radius);

 v += sum(float2(-0.9, -0.4), radius);

 v += sum(float2(-1, 0), radius);

 v += sum(float2(-0.9, 0.4), radius);

 v += sum(float2(-0.7, 0.7), radius);

 v += sum(float2(-0.4, 0.9), radius);

 v += sum(float2(0, 1), radius);

 return v;

}

void main()

{

 float4 c_center = Sample();

 float2 InvResolution = GetInvResolution();

 float4 bloom_sum = float4(0.0, 0.0, 0.0, 0.0);

 position = GetCoordinates() + float2(0.3, 0.3) * InvResolution;

 float2 radius = 4 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 radius = 6.5 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 radius = 9 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 radius = 12.5 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 radius = 16 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 radius = 20.5 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 radius = 25 * InvResolution;

 bloom_sum = bloom(bloom_sum,radius);

 bloom_sum *= 0.0089;// 1/112

 bloom_sum *= 1 - c_center;

 bloom_sum = max(bloom_sum, float4(0.0, 0.0, 0.0, 0.0));

 bloom_sum = min(bloom_sum, float4(1, 1, 1, 1));

 SetOutput(c_center + bloom_sum);

}

Cometí un error con position, lo puse como variable global xD arreglar eso y ya estaría solucionado, soy nuevo en esto.

Google Translation: I made a mistake with position, I put it as global variable xD fix that and it would be fixed by now, I am new to this.

Code:
float4 bloom(float4 v, float2 radius, inout float2 pos);

float4 sum(float2 v, float2 radius, inout float2 pos);

float4 sum(float2 v, float2 radius, inout float2 pos){

 float4 powSample = SampleLocation(pos + v * radius);

 return max((powSample-0.8)*5,float4(0,0,0,0));

}

float4 bloom(float4 v, float2 radius, inout float2 pos){

 v += sum(float2(0.4, 0.9), radius,pos);

 v += sum(float2(0.7, 0.7), radius,pos);

 v += sum(float2(0.9, 0.4), radius,pos);

 v += sum(float2(1, 0), radius,pos);

 v += sum(float2(0.9, -0.4), radius,pos);

 v += sum(float2(0.7, -0.7), radius,pos);

 v += sum(float2(0.4, -0.9), radius,pos);

 v += sum(float2(0, -1), radius,pos);

 v += sum(float2(-0.4, -0.9), radius,pos);

 v += sum(float2(-0.7, -0.7), radius,pos);

 v += sum(float2(-0.9, -0.4), radius,pos);

 v += sum(float2(-1, 0), radius,pos);

 v += sum(float2(-0.9, 0.4), radius,pos);

 v += sum(float2(-0.7, 0.7), radius,pos);

 v += sum(float2(-0.4, 0.9), radius,pos);

 v += sum(float2(0, 1), radius,pos);

 return v;
