DX11 (SOLVED)Error during device creation (D3DERR_NOTAVAILABLE)

Recommended Posts

I am trying to convert the SlimDX device creation tutorial from DX11 to DX9. It is a very simple tutorial where you create a windows add a dx9 device and fill the screen with a solid color. However I am getting a D3DERR_NOTAVAILABLE error thrown when I try and create the device. All the code seems to make sense and it looks very similar to the C# code used in the samples. Any Ideas? NOTE: I create a instance of the BaseDisplayclass and call the InitSlimDX method in another class.

[source lang="vb"]Imports SlimDX.Windows
Imports SlimDX.Direct3D9
Imports SlimDX
Imports Device = SlimDX.Direct3D9.Device
Imports Resource = SlimDX.Direct3D9.Resource
Imports System.Windows.Forms.ThreadExceptionDialog
Imports System.IO

Public Class BaseDisplay
Inherits RenderForm

'SlimDX Class Vars
Protected device As Device = Nothing
Protected backBuffer As Surface
Protected presentParams As PresentParameters

Public Sub New()
Show()
End Sub

Public Sub InitSlimDX()
Dim d3d As Direct3D = New Direct3D()
Dim primaryAdaptor As AdapterInformation = d3d.Adapters().First()

presentParams = New PresentParameters()
With presentParams
.BackBufferWidth = Me.ClientSize.Width
.BackBufferHeight = Me.ClientSize.Height
End With

Me.device = New Device(d3d, primaryAdaptor.Adapter, DeviceType.Hardware, Me.Handle, CreateFlags.HardwareVertexProcessing, presentParams)
Me.device.BeginScene()
backBuffer = device.GetBackBuffer(0, 0)
Me.device.ColorFill(backBuffer, New Color4(Color.CornflowerBlue))
Me.device.EndScene()
Me.device.Present()
End Sub

Public Overloads Sub Dispose()
device.Dispose()
MyBase.Dispose()
End Sub
End Class[/source]

I figured out what my problem was. Earlier I was messing with my DX9 settings in the DirectX control panel and for some reason I enabled the "Software Only" setting which disabled hardware acceleration. disabling this option fixed the issue. Thanks.

      How do i open an image to use it as Texture2D information without D3DX11CreateShaderResourceViewFromFile? And how it works for different formats like (JPG, PNG, BMP, DDS,  etc.)?
      I have an (512 x 512) image with font letters, also i have the position and texcoord of every letter. The main idea is that i want to obtain the image pixel info, use the position and texcoords to create a new texture with one letter and render it. Or am I wrong in something?

      Hey,
      I found a very interesting blog post here: https://bartwronski.com/2017/04/13/cull-that-cone/
      However, I didn't really got how to use his "TestConeVsSphere" test in 3D (last piece of code on his post). I have the frustumCorners of a 2D Tile cell in ViewSpace and my 3D Cone Origin and Direction, so where to place the "testSphere"? I thought about to also move the Cone into viewspace and put the sphere to the Center of the Cell with the radius of half-cellsize, however what about depth? A sphere does not have inf depth?
      I am missing anything? Any Ideas?
      Thx, Thomas

      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++?
