How could I implement a bleach bypass shader effect for WPF?
I'm also interested in the possibility of implementing the first two Tehnicolor Film Processes, or any variety that would result in an old film look.
Check out: http://developer.download.nvidia.com/shaderlibrary/packages/post_bleach_bypass.fx.zip
The important part is:
float4 bypassPS(QuadVertexOutput IN, uniform sampler2D SceneSampler) : COLOR
{
float4 base = tex2D(SceneSampler, IN.UV);
float3 lumCoeff = float3(0.25,0.65,0.1);
float lum = dot(lumCoeff,base.rgb);
float3 blend = lum.rrr;
float L = min(1,max(0,10*(lum- 0.45)));
float3 result1 = 2.0f * base.rgb * blend;
float3 result2 = 1.0f - 2.0f*(1.0f-blend)*(1.0f-base.rgb);
float3 newColor = lerp(result1,result2,L);
float A2 = Opacity * base.a;
float3 mixRGB = A2 * newColor.rgb;
mixRGB += ((1.0f-A2) * base.rgb);
return float4(mixRGB,base.a);
}

So im making a game right now, and i wanna have texture on my cubes,
I have my shaders ready, but not my code (i think)
So whats happening right now, is nothing, the cube stays the default white i set.
Any idea why?
Shader:
Texture2D Texture0 : register(t0);
SamplerState Sampler : register(s0);
float4 PSMain(PixelShaderInput pixel) : SV_Target
{
float3 normal = normalize(pixel.WorldNormal);
float3 toEye = normalize(CameraPosition - pixel.WorldPosition);
float3 toLight = normalize(-Light.Direction);
float4 sample = (float4)1.0f;
if (HasTexture)
sample = Texture0.Sample(Sampler, pixel.TextureUV);
float3 ambient = MaterialAmbient.rgb;
float3 emissive = MaterialEmissive.rgb;
float3 diffuse = Lambert(pixel.Diffuse, normal, toLight);
float3 specular = SpecularPhong(normal, toLight, toEye);
float3 color = (saturate(ambient+diffuse) * sample.rgb + specular) * Light.Color.rgb + emissive;
float alpha = pixel.Diffuse.a * sample.a;
return float4(color, alpha);
}
Renderer:
var srv = ShaderResourceView.FromFile(device, "texture.png");
var material = new ConstantBuffers.PerMaterial()
{
Ambient = mat.Ambient,
Diffuse = mat.Diffuse,
Emissive = mat.Emissive,
Specular = mat.Specular,
SpecularPower = mat.SpecularPower,
UVTransform = Matrix.Translation(1f, 0f, 0f)
};
int texIndxOffset = mIndx * Mesh.MaxTextures;
material.HasTexture = (uint)(text != null && text.texture != null ? 1 : 0);
context.PixelShader.SetShaderResource(0, (text != null && text.texture != null ? text.texture : null));
context.PixelShader.SetSampler(0, samplerState);
context.UpdateSubresource(ref material, PerMaterialBuffer);
context.InputAssembler.SetVertexBuffers(0, new VertexBufferBinding(vertexBuffer, Utilities.SizeOf<Vertex>(), 0));
context.InputAssembler.SetIndexBuffer(indexBuffers[(int)subMesh.IndexBufferIndex], Format.R16_UInt, 0);
context.InputAssembler.PrimitiveTopology = SharpDX.Direct3D.PrimitiveTopology.TriangleList;
context.DrawIndexed((int)subMesh.PrimCount * 3, (int)subMesh.StartIndex, 0);
So i fixed it, i am not really sure what fixed it but its working now.
It was something with the Shader and my Code.
I am working on a cel shader for a uni project that I would like to only be affected by scene lights over x intensity. I am struggling in figuring out how to implement this within the code. The code I have been working with I found online, and have been using it to test and understand how shaders work. I am unsure if I need to implement some kind of conditional statement? Some of the information I have read has said that using conditional statements within shaders makes for poor performance.
I am new to shaders and any help would be greatly appreciated.
Thank you in advance :)
ps. I am limited to using Unity 2018.3.8

Okay, so this problem is kinda huge, and for the same reason i would rather post as little code as possible, but rather have you come with ideas as to what it could be. I will post the codere where i feel the problem could be. If you would like to see more just ask and i will provide it.
So, i just "stole" a shader for my game. By stole i mean found a tutorial that i had done before, and just copied the end result. Thus i know the shader should work, because i've used it before.
I have a custom mesh class, and also a custom vertex struct. I have never done a xertex struct before so initially i thought this is where the problem was.
But i have some counterarguments i later found:
All of their variables seems to be right, and everything works except the bump-mapping.
Changing the Tangent and/or binormal seems to have no effect on the shading what-so-ever. So i think the mistake is not in how they are calulated, but rather how they are used.
http://imageshack.us/photo/my-images/838/w6kv.png/
This is the output i get. Keep in mind that this is a voxel engine. As you can see all the boxes has the same wierd normal-map shadow. However this is the normal map:
http://imageshack.us/photo/my-images/268/r7jt.jpg/
As you can see, they don't fit whatsoever. Now, this could be one of three things as i see it:
It could be the way i set up the shader in xna.
It could also be something in the vertex struct
It could also be the way i call the actual drawing function.
So here's the code for those three things (And the shader as well):
Shader Setup:
((Here i set up the data for the shader, and the draw the mesh))
// Bind the parameters with the shader.
BBS.Parameters["World"].SetValue(Matrix.Identity);
BBS.Parameters["View"].SetValue(camera.viewMatrix);
BBS.Parameters["Projection"].SetValue(camera.projectionMatrix);
BBS.Parameters["AmbientColor"].SetValue(Color.White.ToVector4());
BBS.Parameters["AmbientIntensity"].SetValue(0.5f);
Vector3 LD = new Vector3(0, 1, -1);
LD.Normalize();
BBS.Parameters["DiffuseColor"].SetValue(Color.White.ToVector4());
BBS.Parameters["DiffuseIntensity"].SetValue(0);
BBS.Parameters["LightDirection"].SetValue(LD);
BBS.Parameters["EyePosition"].SetValue(new Vector3(0.0f, 2.0f, 5.0f));
BBS.Parameters["SpecularColor"].SetValue(Color.White.ToVector4());
BBS.Parameters["ColorMap"].SetValue(cubeTexture);
BBS.Parameters["NormalMap"].SetValue(Content.Load<Texture2D>("images"));
BBS.CurrentTechnique = BBS.Techniques["Technique1"];
for (int i = 0; i < BBS.CurrentTechnique.Passes.Count; i++)
{
//EffectPass.Apply will update the device to
//begin using the state information defined in the current pass
BBS.CurrentTechnique.Passes[i].Apply();
//theMesh contains all of the information required to draw
//the current mesh
graphics.DrawUserPrimitives(PrimitiveType.TriangleList, Mesh.Vertices, 0, Mesh.NUM_TRIANGLES);
}
Vertex struct:
public struct VertexPositionNormalTangentBinormalTexture : IVertexType
{
public Vector3 Position;
public Vector3 Normal;
public Vector2 TextureCoordinate;
public Vector3 Tangent;
public Vector3 Binormal;
public static readonly VertexDeclaration VertexElements = new VertexDeclaration

new VertexElement(12, VertexElementFormat.Vector3, VertexElementUsage.Normal, 0),

output.WorldToTangentSpace[1] = mul(normalize(input.Binormal), World);
output.WorldToTangentSpace[2] = mul(normalize(input.Normal), World);
It Should Be Like This:
output.WorldToTangentSpace[0] = normalize(mul(input.Tangent, World));
output.WorldToTangentSpace[1] = normalize(mul(input.Binormal, World));
output.WorldToTangentSpace[2] = normalize(mul(input.Normal, World));
Otherwise, Your Normals Will Get Scaled From The World-space Transformation And Will Result In Very Bright And Very Dark Patches (Which Looks Like Your Problem). BTW, Seeing As You're Interested In Normal Mapping For Voxel Engines, Check Out The Following That I Had Made:

Hope You Get Inspired And That You Complete Your Project.
I'm wondering if there is a difference between GLSL and HLSL Mathematics.
I'm using a selfmade Engine which works with openTK fine. My SharpDx Implementation gets everyday a bit further.
I'm currently working on the ModelviewProjection Matrix.
To see if it works I use a simple project which works fine with OpenTK.
So I changed the Shader code from GLSL to HLSL because the rest of the program uses the engine functions. The programm did not work I couldn't see the geometry, so I changed the Modelview Matrix and the Projections Matrix to the Identity Matrix. Aftwards it worked I saw the geometry. So I changed a bit of the GLSL becuase I wanted a similar GLSL code to the HLSL and I also changed the Matrixes to the identy too. Afterwards I did not see anything it didn't work.... So I'm stuck... Any of you have an Idea?
Anyways long story short
My HLSL Shader Code
public string Vs = #"cbuffer Variables : register(b0){
float4 Testfarbe;
float4x4 FUSEE_MVP;
}
struct VS_IN
{
float4 pos : POSITION;
float4 tex : TEXCOORD;
float4 normal : NORMAL;
};
struct PS_IN
{
float4 pos : SV_POSITION;
float4 col : COLOR;
float4 tex : TEXCOORD;
float4 normal : NORMAL;
};
PS_IN VS( VS_IN input )
{
PS_IN output = (PS_IN)0;
input.pos.w = 1.0f;
output.pos = mul(input.pos,FUSEE_MVP);
output.col = Testfarbe;
/*output.col = FUSEE_MV._m00_m01_m02_m03;*/
/* output.normal = input.normal;
output.tex = input.tex;*/
/* if (FUSEE_MV._m00 == 4.0f)
output.col = float4(1,0,0,1);
else
output.col = float4(0,0,1,1);*/
return output;
}
";
string Ps = #"
SamplerState pictureSampler;
Texture2D imageFG;
struct PS_IN
{
float4 pos : SV_POSITION;
float4 col : COLOR;
float4 tex : TEXCOORD;
float4 normal : NORMAL;
};
float4 PS( PS_IN input ) : SV_Target
{
return input.col;
/*return imageFG.Sample(pictureSampler,input.tex);*/
}";
So I changed my old working OpenTk project to see where the difference ist between openTK and SharpDx relating to the math calculations.
The HLSL code
public string Vs = #"
/* Copies incoming vertex color without change.
* Applies the transformation matrix to vertex position.
*/
attribute vec4 fuColor;
attribute vec3 fuVertex;
attribute vec3 fuNormal;
attribute vec2 fuUV;
varying vec4 vColor;
varying vec3 vNormal;
varying vec2 vUV;
uniform mat4 FUSEE_MVP;
uniform mat4 FUSEE_ITMV;
void main()
{
gl_Position = FUSEE_MVP * vec4(fuVertex, 1.0);
/*vNormal = mat3(FUSEE_ITMV[0].xyz, FUSEE_ITMV[1].xyz, FUSEE_ITMV[2].xyz) * fuNormal;*/
vUV = fuUV;
}";
public string Ps = #"
/* Copies incoming fragment color without change. */
#ifdef GL_ES
precision highp float;
#endif
uniform vec4 vColor;
varying vec3 vNormal;
void main()
{
gl_FragColor = vColor * dot(vNormal, vec3(0, 0, 1));
}";
In the main code itself I only read an Obj file and set the Identity matrix
public override void Init()
{
Mesh = MeshReader.LoadMesh(#"Assets/Teapot.obj.model");
//ShaderProgram sp = RC.CreateShader(Vs, Ps);
sp = RC.CreateShader(Vs, Ps);
_vTextureParam = sp.GetShaderParam("Testfarbe");//vColor
}
public override void RenderAFrame()
{
...
var mtxRot = float4x4.CreateRotationY(_angleHorz) * float4x4.CreateRotationX(_angleVert);
var mtxCam = float4x4.LookAt(0, 200, 500, 0, 0, 0, 0, 1, 0);
// first mesh
RC.ModelView = float4x4.CreateTranslation(0, -50, 0) * mtxRot * float4x4.CreateTranslation(-150, 0, 0) * mtxCam;
RC.SetShader(sp);
//mapping
RC.SetShaderParam(_vTextureParam, new float4(0.0f, 1.0f, 0.0f, 1.0f));
RC.Render(Mesh);
Present();
}
public override void Resize()
{
RC.Viewport(0, 0, Width, Height);
float aspectRatio = Width / (float)Height;
RC.Projection = float4x4.CreatePerspectiveFieldOfView(MathHelper.PiOver4, aspectRatio, 1, 5000);
}
The both programs side by side
What I should also add is as soon as the values of my ModelView identity are bigger than 1.5 I don't see anything in my window ? anyone knows that might causing this?
I edited the Post and the Image so you see a bigger difference.
I had earlier in this post the identity Matrix. If I use the Identity Matrix with this Obj-File
v 0.0 0.5 0.5
v 0.5 0.0 0.5
v -0.5 0.0 0.5
vt 1 0 0
vt 0 1 0
vt 0 0 0
f 1/2 2/3 3/1
I saw in my SharpDX project the triangle and in my openTK not. But I tink the Teapot thing is a bit better to show the difference within the to project where only the Shadercode is different! I mean I could've done something wrong in the SharpDX Implementation for this Enginge but lets assume their is everything right. At least I hope so if you guys tell my the ShaderCode is just wrong ;)
I hope I could describe my problem clear so you understand it.
OK So you've to Transpose the Matrix...
i have o problem with my shader code (HLSL). I use "DirectX for Managed Code" and Shader Model 3.0. I try to write a custom depth value into the depth buffer by using the DEPTH semantic in the pixel shader output struct:
struct PSOutput
{
float4 col : COLOR0;
float dept : DEPTH;
};
and i use this struct as return value in my pixel shader:
PSOutput PSFunction(VertexShaderOutput input)
{
PSOutput output;
...
output.col = float4(...);
output.dept = ...;
return output;
}
DirectX throws an exeption when i try to compile this shader, but gives no detailed information why. But when i remove the depth variable from the output struct it works! I also tried to write DEPTH0 as semantic, but no success. I hope anyone can help my with that.
EDIT:
If i write the following, it fails:
PSOutput PSFunction(VertexShaderOutput input)
{
PSOutput output;
float resDepth = input.Position[2] / input.Position[3];
if(...)
{
resDepth = ...;
}
output.col = float4(...);
output.dept = resDepth;
return output;
}
but if i write this code, it compiles:
PSOutput PSFunction(VertexShaderOutput input)
{
PSOutput output;
float resDepth = input.Position[2] / input.Position[3];
if(...)
{
resDepth = ...;
}
output.col = float4(...);
output.dept = 0.5;
return output;
}
any ideas?

If FXC is throwing an exception during compilation rather than giving you a compilation error it's probably not anything you've done wrong.
If you're using the DirectX SDK make sure you're using the most recent version (June 2010). If you're using the Windows Kit 8.0 SDK then you may have found a compiler bug. What version of the SDK / fxc are you using?
Can you post a shader that actually compiles (one with the missing VertexShaderOutput struct and without ...'s in place of actual code)? I've filled in the missing code and have no problem compiling it using fxc from Windows Kit 8.0.
EDIT:
Nope, I hadn't spotted you'd commented out the code that made it not compile.
Sure enough, it doesn't compile, but that's because it's not valid code (as reported by the compile errors). You're using the POSITION semantic as an input to your pixel shader, which is not valid. If you want to use the outputted position from a vertex shader as input to a pixel shader, copy it into a second attribute and use that instead. If I substitute the following code into your shader it then compiles:
struct VertexShaderOutput
{
float4 ClipPosition : POSITION; // Renamed this to ClipPosition.
float4 Position : TEXCOORD0; // This is valid to use as an input to the pixel shader.
float3 Normal : NORMAL;
float3 ExactPos : TEXCOORD1;
};
struct PSOutput
{
float4 col : COLOR0;
float dept : DEPTH;
};
VertexShaderOutput VSFunction(VertexShaderInput input)
{
VertexShaderOutput output;
float4 worldPosition = mul(input.Position, World);
float4 viewPosition = mul(worldPosition, View);
output.ClipPosition = mul(viewPosition, Projection);
output.Position = output.ClipPosition; // Copy output position to our other attribute.
output.Normal = mul(input.Normal, World);
output.ExactPos = input.Position;
return output;
}
