I was gonna work on it tonight, but then I took my parents to see The Dark Knight <.< Might still get something done though.

i think the entire thing, apart from the stretch to 800x600 part can be done with math alone.


Even a shader implementation of blargg's NTSC emulator can be done, I know the author of pSX managed to do it, with some help from some coefficient textures and with it being a multipass shader...

Hheheh, found something super cool:
http://boris-vorontsov.narod.ru/index_en.html

A Russian is using the same idea as I (hooking D3D calls and reprocessing frames), but he has done it for specific games. Which is certainly cool, as he made depth of field effects and SSAO (screenspace ambience occlusion) shaders. He also made a DLL that wraps D3D8 to D3D9, which is super cool for old games.

Just thought of pointing it out, as making mods for specific games, is really cool, and it works rather well...

Although it looks 10x more realistic it also looks very blurry

Awesomely done though

dude went overboard with compression on some photos, thats for sure.

but the fact you can tell the difference with the compression that high...

And thats what SSAO is designed for: Realism in lighting.

Learning Shaders

Post by gllt »

I'm learning shaders by editing the presets, reading tutorials, and mostly screwing with the math since that's the easiest place to start.

So anyway, here is the first shader I'm actually keeping that I modded from the Red color shader. It achieves a red/blue effect I'm a fan of.

http://www.savefile.com/files/1760510
Shader Download

Code: Select all

//These variables will get set automatically
texture tex1;

float2 rcpres;

sampler s0 = sampler_state { texture = <tex1>; };

float4 NormalColourPass( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex );
   color.a = 1;
   return color;
}

float4 DiffColourPass( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex.xy);
  color.gb = color.r+color.g-color.b;
  color.r = color.r/3+color.a/5;
   return color;
}

Technique T0
{

    pass p0 { PixelShader = compile ps_2_0 NormalColourPass(); }
    pass p1 { PixelShader = compile ps_2_0 DiffColourPass(); }
}



Shader Code (Simple Edit but learning takes time, right? Plus I love those colors together like that, I've used them that way in many things and screwing around with the math I was shocked to come upon them.)

Super Mario 64. Haven't tried BSNES yet, though results should be obvious. No longer true. See ZAMN examples. +DKC2 cause it looks beautiful. All BSNES Scale2x Linear.

Hope sharing this isn't too off-topic.

Nah, isnt off topic at all.

Sharing shaders is intended and encouraged, so what you are doing is great! :)

I'll check out the shader and fix the DL link when I have a chance.

float4 NormalColourPass( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex );
   color.a = 1;
   return color;
}

float4 RChannel( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex.xy);
  color.r = color.r - color.gb;
  color.gb = color.r;
   return color;
}

float4 GChannel( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex.xy);
  color.g = color.g - color.rb;
  color.rb = color.g;
   return color;
}


float4 BChannel( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex.xy);
  color.b = color.b - color.rg;
  color.rg = color.b;
   return color;
}

Technique T0
{

    pass p0 { PixelShader = compile ps_2_0 NormalColourPass(); }
    pass p1 { PixelShader = compile ps_2_0 RChannel(); }
    pass p2 { PixelShader = compile ps_2_0 GChannel(); }
    pass p3 { PixelShader = compile ps_2_0 BChannel(); }
}


That should separate the "channels", but I don't know how to re-blend them. Could be useful.

EDIT;

At the moment I'm trying to separate the "channels" (rgba) into "layers".
I've sort of managed to do it with two samplers and textures, where s1 renders into s0, but actually more or less renders its effects over s0 and its rendered effects. i.e. s0 says red is green, but s1 says red is blue, so in the final render, red is blue. Not red is green so red(green) is blue. I'm also experimenting with removing a "channel" on a "layer", but I'm not much sucessful, and in some situations the above problems seems inverted (red IS green, so red(green) IS blue, i.e. color.r = -color.r on s1 removes the red "channel" in the entire final render, not just s1.)

Code: Select all

float4 NormalColourPass( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex );
   color.a = 1;
   color.gb = color.r/6;
   return color;
}



Produces a red-only somewhat filter. Reminded me of virtual boy at first, but causes some problems. In Zombies Ate My Neighbors, the green hedges are black like the grass is also made black, so therefore INVISIBLE. Now, if I could under/overlay the green and blue channels again in a red tint that is dimmer than in the other layer, I could restore the visibility and improve the effect, but this is where I'm halted.

But I'm clueless to most of this language and Google isn't helping I'm afraid, so most of what I'm saying is based on rigorous testing and uh, guessing. So it's likely to be complete erroneous gibberish.

Any input totally welcome! Really!

EDIT;
OT; Why is the patcher so.. risque? Any chance of a clean version, I mean I can't complain but, I don't want anyone to get the wrong idea of what I'm doing on the computer. :P

EDITEDITEDIT; Sorry for mega-post.

Code: Select all

Trying to convert tex to sphere render code from media player classic shaders (i.e. this is not my code, all I did was add the pass p0 command. So far it's rendering the texture back, but to a canvas, not a rotating sphere.)

Sorry for second post but that one there was getting out of hand, I thought a fresh result deserves a fresh post.

Anyway,

Code: Select all

//These variables will get set automatically
texture tex1;
texture tex2;

float2 rcpres;

sampler s0 = sampler_state { texture = <tex1>; };
sampler s1 = sampler_state { texture = <tex2>; };

float4 NormalColourPass( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s0, Tex );
   color.a = 1;
   color.gb = color.r/6;
   return color;
}

float4 DiffColourPass( in float2 Tex : TEXCOORD0 ) : COLOR0
{
   float4 color = tex2D( s1, Tex.xy);
   color.a = 0.5;
  color.gb = color.gb*6;
  color.r = color.r*6;
   return color;
}

Technique T0
{

    pass p0 { PixelShader = compile ps_2_0 NormalColourPass(); }
    pass p1 { PixelShader = compile ps_2_0 DiffColourPass(); }
}



Results; http://i36.tinypic.com/2ziydeg.png

I think the code is probably redundant, but I'm too tired to check it, otherwise I think this is just a result of over-brightness. It makes the invisible areas semi-visible, but the visible areas dramatically bright.

Perhaps its a step in the right direction towards my goal, though.

EDIT; original effect that led to this interest (comment out diffcolourpass section for testing)

EDIT; LTTP tests on ver1 (hard-red, not overbright) seem better than ZAMN. Did DKC2 but no screens, was too busy playing/having eyes burnt out.

Place into red color filter etc, trying to trim to only the changed code.
Gonna release a pack of filters though eventually, sorting out ones that are eh for ones that I like. Only colors for now though.

Modified the regular toon shader, I like how it makes OOT look.
Find and make x line look like so in toon shader.

Code: Select all

   float edge =(x*x + y*y < threshold)? 2.0:1.5;

gllt your shaders are awesome.

i wonder would you be able to make this?:
