From f3d341a544cf6e657859a699af52886c5ac87269 Mon Sep 17 00:00:00 2001 From: Ryan Holtz Date: Mon, 16 May 2011 16:55:34 +0000 Subject: Initial shader import (nw) Focus: 8-sample blur that averages 7 samples around a center sample. Phosphor: Not currently used, treated as a pass-through by drawd3d.c, but could be used to implement additional convolutions in a second pass. Pincushion: Used (when commented in in drawd3d.c) to pincushion an entire full-screen texture but not otherwise apply any convolutions. Post: The meat and potatoes. It does scanlines, it does aperture masking, it does dot crawl, it does chroma subsampling, it does YIQ colorspace convolution, it does RGB colorspace convolution, it does pincushioning, it walks, it talks, it does the dishes, it'll screw your wife for you, and if you don't have a wife it will find one for you, get you married to her, and screw her for you, IT IS THAT GOOD, LADIES AND GENTLEMEN. Primary: Simple passthrough for UI and artwork. --- hlsl/focus.fx | 140 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 140 insertions(+) create mode 100644 hlsl/focus.fx (limited to 'hlsl/focus.fx') diff --git a/hlsl/focus.fx b/hlsl/focus.fx new file mode 100644 index 00000000000..8856b06a6da --- /dev/null +++ b/hlsl/focus.fx @@ -0,0 +1,140 @@ +//----------------------------------------------------------------------------- +// Effect File Variables +//----------------------------------------------------------------------------- + +texture Diffuse; + +sampler DiffuseSampler = sampler_state +{ + Texture = ; + MipFilter = LINEAR; + MinFilter = LINEAR; + MagFilter = LINEAR; + AddressU = CLAMP; + AddressV = CLAMP; + AddressW = CLAMP; +}; + +//----------------------------------------------------------------------------- +// Vertex Definitions +//----------------------------------------------------------------------------- + +struct VS_OUTPUT +{ + float4 Position : POSITION; + float4 Color : COLOR0; + float2 TexCoord0 : TEXCOORD0; + float2 TexCoord1 : TEXCOORD1; + float2 TexCoord2 : TEXCOORD2; + float2 TexCoord3 : TEXCOORD3; + float2 TexCoord4 : TEXCOORD4; + float2 TexCoord5 : TEXCOORD5; + float2 TexCoord6 : TEXCOORD6; + float2 TexCoord7 : TEXCOORD7; +}; + +struct VS_INPUT +{ + float3 Position : POSITION; + float4 Color : COLOR0; + float2 TexCoord : TEXCOORD0; + float2 ExtraInfo : TEXCOORD1; +}; + +struct PS_INPUT +{ + float4 Color : COLOR0; + float2 TexCoord0 : TEXCOORD0; + float2 TexCoord1 : TEXCOORD1; + float2 TexCoord2 : TEXCOORD2; + float2 TexCoord3 : TEXCOORD3; + float2 TexCoord4 : TEXCOORD4; + float2 TexCoord5 : TEXCOORD5; + float2 TexCoord6 : TEXCOORD6; + float2 TexCoord7 : TEXCOORD7; +}; + +//----------------------------------------------------------------------------- +// Simple Vertex Shader +//----------------------------------------------------------------------------- + +uniform float TargetWidth; +uniform float TargetHeight; +uniform float DefocusX; +uniform float DefocusY; +uniform float FocusEnable; + +float2 Coord0Offset = float2( 0.0f, 0.0f); +float2 Coord1Offset = float2(-0.2f, -0.6f); +float2 Coord2Offset = float2( 0.4f, -0.4f); +float2 Coord3Offset = float2( 0.6f, 0.2f); +float2 Coord4Offset = float2( 0.2f, 0.6f); +float2 Coord5Offset = float2(-0.4f, 0.6f); +float2 Coord6Offset = float2(-0.6f, 0.2f); +float2 Coord7Offset = float2(-0.6f, -0.4f); + +VS_OUTPUT vs_main(VS_INPUT Input) +{ + VS_OUTPUT Output = (VS_OUTPUT)0; + + Output.Position = float4(Input.Position.xyz, 1.0f); + Output.Position.x /= TargetWidth; + Output.Position.y /= TargetHeight; + Output.Position.y = 1.0f - Output.Position.y; + Output.Position.x -= 0.5f; + Output.Position.y -= 0.5f; + Output.Position *= float4(2.0f, 2.0f, 1.0f, 1.0f); + Output.Color = Input.Color; + + float2 InvTexSize = float2(1.0f / TargetWidth, 1.0f / TargetHeight); + float2 TexCoord = Input.Position.xy * InvTexSize; + float2 DefocusVal = float2(DefocusX, DefocusY); + Output.TexCoord0 = TexCoord + Coord0Offset * InvTexSize * DefocusVal; + Output.TexCoord1 = TexCoord + Coord1Offset * InvTexSize * DefocusVal; + Output.TexCoord2 = TexCoord + Coord2Offset * InvTexSize * DefocusVal; + Output.TexCoord3 = TexCoord + Coord3Offset * InvTexSize * DefocusVal; + Output.TexCoord4 = TexCoord + Coord4Offset * InvTexSize * DefocusVal; + Output.TexCoord5 = TexCoord + Coord5Offset * InvTexSize * DefocusVal; + Output.TexCoord6 = TexCoord + Coord6Offset * InvTexSize * DefocusVal; + Output.TexCoord7 = TexCoord + Coord7Offset * InvTexSize * DefocusVal; + + return Output; +} + +//----------------------------------------------------------------------------- +// Simple Pixel Shader +//----------------------------------------------------------------------------- + +float4 ps_main(PS_INPUT Input) : COLOR +{ + float3 d0 = tex2D(DiffuseSampler, Input.TexCoord0).rgb; + float3 d1 = tex2D(DiffuseSampler, Input.TexCoord1).rgb; + float3 d2 = tex2D(DiffuseSampler, Input.TexCoord2).rgb; + float3 d3 = tex2D(DiffuseSampler, Input.TexCoord3).rgb; + float3 d4 = tex2D(DiffuseSampler, Input.TexCoord4).rgb; + float3 d5 = tex2D(DiffuseSampler, Input.TexCoord5).rgb; + float3 d6 = tex2D(DiffuseSampler, Input.TexCoord6).rgb; + float3 d7 = tex2D(DiffuseSampler, Input.TexCoord7).rgb; + + float3 blurred = (d0 + d1 + d2 + d3 + d4 + d5 + d6 + d7) / 8.0f; + + blurred = lerp(d0, blurred, FocusEnable); + return float4(blurred, 1.0f); +} + +//----------------------------------------------------------------------------- +// Simple Effect +//----------------------------------------------------------------------------- + +technique TestTechnique +{ + pass Pass0 + { + Lighting = FALSE; + + Sampler[0] = ; + + VertexShader = compile vs_2_0 vs_main(); + PixelShader = compile ps_2_0 ps_main(); + } +} -- cgit v1.2.3
