HLSL高级应用实例
废话少说，直接入题。
先给出整个应用程序构架：
Code
HLSL代码如下：
HLSL这是默认的效果，效果图如下：
1
float4 PSfun(PSInput input) : COLOR0
2
{
3
//负片效果
4 return(1- float4(color*AmbientColor) );
5
}
float4 PSfun(PSInput input) : COLOR02
{3
//负片效果4
return(1- float4(color*AmbientColor) );5
}
模糊效果:
1float4 PSfun(PSInput input) : COLOR0
2{
3 //模糊效果
4 float4 color = float4( tex2D( TextureSampler,float2(input.texcoord.x+0.0025, input.texcoord.y+0.025))*AmbientColor);
5 color += tex2D( TextureSampler,float2(input.texcoord.x-0.025, input.texcoord.y-0.025));
6 color += tex2D( TextureSampler,float2(input.texcoord.x+0.025, input.texcoord.y-0.025));
7 color += tex2D( TextureSampler,float2(input.texcoord.x-0.025, input.texcoord.y+0.025));
8 color = color / 4;
9 return( color );
10}
float4 PSfun(PSInput input) : COLOR02
{3
//模糊效果4
float4 color = float4( tex2D( TextureSampler,float2(input.texcoord.x+0.0025, input.texcoord.y+0.025))*AmbientColor);5
color += tex2D( TextureSampler,float2(input.texcoord.x-0.025, input.texcoord.y-0.025));6
color += tex2D( TextureSampler,float2(input.texcoord.x+0.025, input.texcoord.y-0.025));7
color += tex2D( TextureSampler,float2(input.texcoord.x-0.025, input.texcoord.y+0.025));8
color = color / 4;9
return( color );10
}
浮雕效果:
1float4 PSfun(PSInput input) : COLOR0
2{
3 //浮雕
4 float sharpAmount = 15.0f;
5 float4 color;
6 color.rgb = 0.5f;
7 color.a = 1.0f;
8 color -= float4( tex2D( TextureSampler, input.texcoord - 0.0001) * sharpAmount*AmbientColor);
9 color += float4( tex2D( TextureSampler, input.texcoord + 0.0001) * sharpAmount*AmbientColor);
10 color = (color.r+color.g+color.b) / 3.0f;
11 return( color );
12}
float4 PSfun(PSInput input) : COLOR02
{3
//浮雕4
float sharpAmount = 15.0f;5
float4 color;6
color.rgb = 0.5f;7
color.a = 1.0f;8
color -= float4( tex2D( TextureSampler, input.texcoord - 0.0001) * sharpAmount*AmbientColor);9
color += float4( tex2D( TextureSampler, input.texcoord + 0.0001) * sharpAmount*AmbientColor);10
color = (color.r+color.g+color.b) / 3.0f;11
return( color );12
}
Grayscale:
1float4 PSfun(PSInput input) : COLOR0
2{
3 //Grayscale
4 float4 color =float4(tex2D(TextureSampler, input.texcoord)*AmbientColor);
5 float4 gs = dot(color.rgb, float3(0.3, 0.59, 0.11));
6 if (input.texcoord.x > 0.5f)
7 color = lerp(gs, color, (1 - input.texcoord.x) * 2);
8 else
9 color = lerp(gs, color, input.texcoord.x * 2);
10 return( color );
11}
float4 PSfun(PSInput input) : COLOR02
{3
//Grayscale4
float4 color =float4(tex2D(TextureSampler, input.texcoord)*AmbientColor);5
float4 gs = dot(color.rgb, float3(0.3, 0.59, 0.11));6
if (input.texcoord.x > 0.5f)7
color = lerp(gs, color, (1 - input.texcoord.x) * 2);8
else9
color = lerp(gs, color, input.texcoord.x * 2);10
return( color );11
}
粉笔效果:
1float4 PSfun(PSInput input) : COLOR0
2{
3 //粉笔
4 float sharpAmount = 100.0f;
5 float4 color = float4(tex2D(TextureSampler, input.texcoord)*AmbientColor);
6 color += tex2D( TextureSampler, input.texcoord - 0.001) * sharpAmount;
7 color -= tex2D( TextureSampler, input.texcoord + 0.001) * sharpAmount;
8 return( color );
9}
float4 PSfun(PSInput input) : COLOR02
{3
//粉笔4
float sharpAmount = 100.0f;5
float4 color = float4(tex2D(TextureSampler, input.texcoord)*AmbientColor);6
color += tex2D( TextureSampler, input.texcoord - 0.001) * sharpAmount;7
color -= tex2D( TextureSampler, input.texcoord + 0.001) * sharpAmount;8
return( color );9
}
波动效果:
1float4 PSfun(PSInput input) : COLOR0
2{
3 //动的
4 float y = input.texcoord.y;
5 float x = input.texcoord.x;
6 y = y + (sin(x*100)*0.01);
7 float4 color = float4(tex2D(TextureSampler, float2(x,y))*AmbientColor);
8 return( color );
9}
float4 PSfun(PSInput input) : COLOR02
{3
//动的4
float y = input.texcoord.y;5
float x = input.texcoord.x;6
y = y + (sin(x*100)*0.01);7
float4 color = float4(tex2D(TextureSampler, float2(x,y))*AmbientColor);8
return( color );9
}
