DX11 Basic constant buffer question

Recommended Posts

lonewolff    1183

Hi Guys,

 

Currently I am just using a single shader in my DX11 based project. But, it got me wondering - When using PSSetConstantBuffers() and VSSetConstantBuffers(), how does DX know what shader it is working with? Or is it just assumed by the last SetShader() call?

 

I am guessing that this must be the case. But, I'd rather know for sure than to continue guessing. smile.png

 

Thanks in advance.

Yes, the last SetShader call will determine what shader will run. Methods like SetConstantBuffer bind things to the pipeline (device context), not a specific shader.

 

You can do this for example and both draw calls will use the same constant buffer:

SetConstantBuffer(0, B1)
SetShader(S1)
Draw()
SetShader(S2)
Draw()

      hi all
      I want to enable and disable shader in MPCH Media player Classic
      the MPCH have shader option using HLSL shaders
      I want the shader to read each file extension before it plays the file
      so if the video file name is video.GR.Mp4 it will play it in Grayscale shader 
      if it is not and standard file name Video.Mp4 without GR. unique extension so it plays standard without shader or end the shader
      here is the shader I have for grayscale
      // $MinimumShaderProfile: ps_2_0
      sampler s0 : register(s0);
      float4 main(float2 tex : TEXCOORD0) : COLOR {
          float c0 = dot(tex2D(s0, tex), float4(0.299, 0.587, 0.114, 0));
          return c0;
      }
       
      I want to add if or block stantement or bloean to detect file name before it call the shader in order to go to the procedure or disable it or goto end direct without it
       
      any thoughts or help

      I've gotten to part in my DirectX 11 project where I need to pass the MVP matrices to my vertex shader. And I'm a little lost when it comes to the use of the constant buffer with the vertex shader
      I understand I need to set up the constant buffer just like any other buffer:
      1. Create a buffer description with the D3D11_BIND_CONSTANT_BUFFER flag 2. Map my matrix data into the constant buffer 3. Use VSSetConstantBuffers to actually use the buffer But I get lost at the VertexShader part, how does my vertex shader know to use this constant buffer when we get to the shader side of things
      In the example I'm following I see they have this as their vertex shader, but I don't understand how the shader knows to use the MatrixBuffer cbuffer. They just use the members directly. What if there was multiple cbuffer declarations like the Microsoft documentation says you could have?
      //Inside vertex shader cbuffer MatrixBuffer { matrix worldMatrix; matrix viewMatrix; matrix projectionMatrix; }; struct VertexInputType { float4 position : POSITION; float4 color : COLOR; }; struct PixelInputType { float4 position : SV_POSITION; float4 color : COLOR; }; PixelInputType ColorVertexShader(VertexInputType input) { PixelInputType output; // Change the position vector to be 4 units for proper matrix calculations. input.position.w = 1.0f; // Calculate the position of the vertex against the world, view, and projection matrices. output.position = mul(input.position, worldMatrix); output.position = mul(output.position, viewMatrix); output.position = mul(output.position, projectionMatrix); // Store the input color for the pixel shader to use. output.color = input.color; return output; }

      I am trying to add normal map to my project I have an example of a cube: 
      I have normal in my shader I think. Then I set shader resource view for texture (NOT BUMP)
                  device.ImmediateContext.PixelShader.SetShaderResource(0, textureView);             device.ImmediateContext.Draw(VerticesCount,0); What should I do to set my normal map or how it is done in dx11 generally example c++?

      Imagine that we have a vertex structure that looks like this:
      struct Vertex { XMFLOAT3 position; XMFLOAT4 color; }; The vertex shader looks like this:
      cbuffer MatrixBuffer { matrix world; matrix view; matrix projection; }; struct VertexInput { float4 position : POSITION; float4 color : COLOR; }; struct PixelInput { float4 position : SV_POSITION; float4 color : COLOR; }; PixelInput main(VertexInput input) { PixelInput output; input.position.w = 1.0f; output.position = mul(input.position, world); output.position = mul(output.position, view); output.position = mul(output.position, projection); output.color = input.color; return output; } And the pixel shader looks like this:
      struct PixelInput { float4 position : SV_POSITION; float4 color : COLOR; }; float4 main(PixelInput input) : SV_TARGET { return input.color; } Now let's create a quad consisting of 2 triangles and the vertices A, B, C and D:
      // Vertex A. vertices[0].position = XMFLOAT3(-1.0f, 1.0f, 0.0f); vertices[0].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // Vertex B. vertices[1].position = XMFLOAT3( 1.0f, 1.0f, 0.0f); vertices[1].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // Vertex C. vertices[2].position = XMFLOAT3(-1.0f, -1.0f, 0.0f); vertices[2].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // Vertex D. vertices[3].position = XMFLOAT3( 1.0f, -1.0f, 0.0f); vertices[3].color = XMFLOAT4( 0.5f, 0.5f, 0.5f, 1.0f); // 1st triangle. indices[0] = 0; // Vertex A. indices[1] = 3; // Vertex D. indices[2] = 2; // Vertex C. // 2nd triangle. indices[3] = 0; // Vertex A. indices[4] = 1; // Vertex B. indices[5] = 3; // Vertex D. This will result in a grey quad as shown in the image below. I've outlined the edges in red color to better illustrate the triangles:

      Now imagine that we’d want our quad to have a different color in vertex A:
      // Vertex A. vertices[0].position = XMFLOAT3(-1.0f, 1.0f, 0.0f); vertices[0].color = XMFLOAT4( 0.0f, 0.0f, 0.0f, 1.0f);
      That works as expected since there’s now an interpolation between the black color in vertex A and the grey color in vertices B, C and D. Let’s revert the previus changes and instead change the color of vertex C:
      // Vertex C. vertices[2].position = XMFLOAT3(-1.0f, -1.0f, 0.0f); vertices[2].color = XMFLOAT4( 0.0f, 0.0f, 0.0f, 1.0f);
      As you can see, the interpolation is only done half of the way across the first triangle and not across the entire quad. This is because there's no edge between vertex C and vertex B.
      Which brings us to my question:
      I want the interpolation to go across the entire quad and not only across the triangle. So regardless of which vertex we decide to change the color of, the color interpolation should always go across the entire quad. Is there any efficient way of achieving this without adding more vertices and triangles?
      An illustration of what I'm trying to achieve is shown in the image below:

       
      Background
      This is just a very brief explanation of the problems background in case that would make it easier for you to understand the problems roots and maybe help you with finding a better solution to the problem.
      I'm trying to texture a terrain mesh in DirectX11. It's working, but I'm a bit unsatisfied with the result. When changing the terrain texture of a single vertex, the interpolation with the other vertices results in a hexagon shape instead of a squared shape:

      As the red arrows illustrate, I'd like the texture to be interpolated all the way into the corners of the quads.

      Hello, I'm close to releasing my first game to Steam however, my game keeps failing the review process because it keeps crashing. The problem is that the game doesn't crash on my computer, on my laptop, on our family computer, on fathers laptop and i also gave 3 beta keys to people i know and they said the game hasn't crashed.
      Steam reports that the game doesn't crash on startup but few frames after a level has been started.
      What could cause something like this? I have no way of debugging this as the game works fine on every computer i have.
       
      Game is written in C++, using DirectX 11 and DXUT framework.
