D3D11_BUFFER_DESC bytewidth "not working" - c++

I'm having some issues with Direct3D. Namely the vertex buffer and its ByteWidth member.
I want to draw two quads, so I create my vertex buffer like so:
struct Vertex
{
XMFLOAT3 pos;
XMFLOAT3 normal;
XMFLOAT2 texCoord;
};
....
void GameWindow::CreateVerticesAndBuffer()
{
Vertex vertices[] =
{
{ XMFLOAT3(-1.0f, -1.0f, -1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(0.0f, 1.0f) },
{ XMFLOAT3(-1.0f, 1.0f, -1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(0.0f, 0.0f) },
{ XMFLOAT3(1.0f, 1.0f, -1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(1.0f, 0.0f) },
{ XMFLOAT3(1.0f, -1.0f, -1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(1.0f, 1.0f) },
{ XMFLOAT3(-1.0f, -1.0f, 1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(0.0f, 1.0f) },
{ XMFLOAT3(-1.0f, 1.0f, 1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(0.0f, 0.0f) },
{ XMFLOAT3(1.0f, 1.0f, 1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(1.0f, 0.0f) },
{ XMFLOAT3(1.0f, -1.0f, 1.0f), XMFLOAT3(0.0f, 0.0f, -1.0f), XMFLOAT2(1.0f, 1.0f) }
};
D3D11_BUFFER_DESC desc;
ZeroMemory(&desc, sizeof(desc));
desc.BindFlags = D3D11_BIND_VERTEX_BUFFER;
desc.CPUAccessFlags = 0;
desc.Usage = D3D11_USAGE_DEFAULT; //Will not ever change after creation (??)
desc.MiscFlags = 0;
desc.ByteWidth = sizeof(Vertex) * 8;
desc.StructureByteStride = 0;
D3D11_SUBRESOURCE_DATA data;
ZeroMemory(&data, sizeof(data));
data.pSysMem = vertices;
HR(device->CreateBuffer(
&desc,
&data,
&vertexBuffer));
UINT stride = sizeof(Vertex);
UINT offset = 0;
deviceContext->IASetVertexBuffers(0, 1, &vertexBuffer, &stride, &offset);
}
This code produces some weird results as seen here. The back face is mirrored for some reason.
But, if I change
desc.ByteWidth = sizeof(Vertex) * 8
to
desc.ByteWidth = sizeof(Vertex) * 9
It is drawn correctly.
Does anyone have any idea why this happens?
EDIT: Here is my CreateInputLayout:
D3D11_INPUT_ELEMENT_DESC inputDesc[] = {
{ "POSITION", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 0, D3D11_INPUT_PER_VERTEX_DATA, 0 },
{ "NORMAL", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 12, D3D11_INPUT_PER_VERTEX_DATA, 0 },
{ "TEX", 0, DXGI_FORMAT_R32G32B32_FLOAT, 0, 24, D3D11_INPUT_PER_VERTEX_DATA, 0 }
};
hRes = device->CreateInputLayout(
inputDesc,
ARRAYSIZE(inputDesc),
vertexShaderSource->GetBufferPointer(),
vertexShaderSource->GetBufferSize(),
&vertexInputLayout);


You have specified DXGI_FORMAT_R32G32B32_FLOAT (float3) for your TEX member. Change it to DXGI_FORMAT_R32G32_FLOAT and it should work.

Directx11 Project will not display graphical output

I'm fairly new to Directx, so I have next to no idea what's going on here.
I have confirmed that the initial setup and activation of the window and DirectX API has been successful. However, although the drawing and update functions seem to be fully operational, they still aren't successful at displaying output. I've checked over the linker, my object classes, my effects file, and basically the entire project a dozen times over. Please help!

Reviewing your code and comparing it to the code I've written in the past for DirectX 11 rendering, you are missing at least one thing - a Depth/Stencil State. I'm not certain what the GPU will do if you decide to use a depth/stencil buffer without it, but it looks to be the only difference between the calls your system makes (which doesn't work) and the calls my system makes (which does).
You can create a depth/stencil state with ID3D11Device::CreateDepthStencilState, and set it to the pipeline with ID3D11DeviceContext::OMSetDepthStencilState. This function works the same as ID3D11DeviceContext::OMSetBlendState, in that passing nullptr, NULL or 0 as the state object will bind a default state.

Rendering multiple triangles with a single vertex buffer

Previously I was using a separate vertex and index buffer for each mesh, but I'd like to try using a single large vertex buffer to reduce DrawIndexed() calls. Let's say I have the following arrays:
SimpleVertex vertices[] =
{
{ XMFLOAT3(-1.0f, 1.0f, -1.0f), XMFLOAT4(0.0f, 0.0f, 1.0f, 1.0f) },
{ XMFLOAT3(1.0f, 1.0f, -1.0f), XMFLOAT4(0.0f, 1.0f, 0.0f, 1.0f) },
{ XMFLOAT3(1.0f, 1.0f, 1.0f), XMFLOAT4(0.0f, 1.0f, 1.0f, 1.0f) },
{ XMFLOAT3(-1.0f, 1.0f, 1.0f), XMFLOAT4(1.0f, 0.0f, 0.0f, 1.0f) },
{ XMFLOAT3(-1.0f, -1.0f, -1.0f), XMFLOAT4(1.0f, 0.0f, 1.0f, 1.0f) },
{ XMFLOAT3(1.0f, -1.0f, -1.0f), XMFLOAT4(1.0f, 1.0f, 0.0f, 1.0f) },
{ XMFLOAT3(1.0f, -1.0f, 1.0f), XMFLOAT4(1.0f, 1.0f, 1.0f, 1.0f) },
{ XMFLOAT3(-1.0f, -1.0f, 1.0f), XMFLOAT4(0.0f, 0.0f, 0.0f, 1.0f) },
};
WORD indices[] =
{
3,1,0,
2,1,3,
0,5,4,
1,5,0,
3,4,7,
0,4,3,
1,6,5,
2,6,1,
2,7,6,
3,7,2,
6,4,5,
7,4,6,
};
This works great for a single indexed cube. But, what if I wish to draw two cubes? How do I set up the index buffer to handle that? I'm confused as to whether the indices are local to each cube and thus should just repeat every 36 indices, or if they should be incremented as such:
SimpleVertex vertices[] =
{
//first cube
{ XMFLOAT3(-1.0f, 1.0f, -1.0f), XMFLOAT4(0.0f, 0.0f, 1.0f, 1.0f) },
{ XMFLOAT3(1.0f, 1.0f, -1.0f), XMFLOAT4(0.0f, 1.0f, 0.0f, 1.0f) },
{ XMFLOAT3(1.0f, 1.0f, 1.0f), XMFLOAT4(0.0f, 1.0f, 1.0f, 1.0f) },
{ XMFLOAT3(-1.0f, 1.0f, 1.0f), XMFLOAT4(1.0f, 0.0f, 0.0f, 1.0f) },
{ XMFLOAT3(-1.0f, -1.0f, -1.0f), XMFLOAT4(1.0f, 0.0f, 1.0f, 1.0f) },
{ XMFLOAT3(1.0f, -1.0f, -1.0f), XMFLOAT4(1.0f, 1.0f, 0.0f, 1.0f) },
{ XMFLOAT3(1.0f, -1.0f, 1.0f), XMFLOAT4(1.0f, 1.0f, 1.0f, 1.0f) },
{ XMFLOAT3(-1.0f, -1.0f, 1.0f), XMFLOAT4(0.0f, 0.0f, 0.0f, 1.0f) },
//second cube
{ XMFLOAT3(-2.0f, 2.0f, -2.0f), XMFLOAT4(0.0f, 0.0f, 1.0f, 1.0f) },
{ XMFLOAT3(2.0f, 2.0f, -2.0f), XMFLOAT4(0.0f, 1.0f, 0.0f, 1.0f) },
{ XMFLOAT3(2.0f, 2.0f, 2.0f), XMFLOAT4(0.0f, 1.0f, 1.0f, 1.0f) },
{ XMFLOAT3(-2.0f, 2.0f, 2.0f), XMFLOAT4(1.0f, 0.0f, 0.0f, 1.0f) },
{ XMFLOAT3(-2.0f, -2.0f, -2.0f), XMFLOAT4(1.0f, 0.0f, 1.0f, 1.0f) },
{ XMFLOAT3(2.0f, -2.0f, -2.0f), XMFLOAT4(1.0f, 1.0f, 0.0f, 1.0f) },
{ XMFLOAT3(2.0f, -2.0f, 2.0f), XMFLOAT4(1.0f, 1.0f, 1.0f, 1.0f) },
{ XMFLOAT3(-2.0f, -2.0f, 2.0f), XMFLOAT4(0.0f, 0.0f, 0.0f, 1.0f) },
};
WORD indices[] =
{
//First cube
3,1,0,
2,1,3,
0,5,4,
1,5,0,
3,4,7,
0,4,3,
1,6,5,

10,14,9,
10,15,14,
11,15,10,
14,12,13,
15,12,14,
};
So basically, I'm trying to understand how to draw one large index buffer with multiple objects. Am I thinking about this correctly or should I have the buffer re-use the same index buffer over and over?
I'm aware of using Instancing, but there are times where the geometry changes, so I need to avoid it in this case.

Decided to just start writing code to attack the theory blind. Turns out you do indeed need to increment the index array to treat a large vertex array as one mesh. I wrote a function to illustrate this for those interested:
UINT* VertexCompiler::BuildIndexArray()
{
UINT* indices;
int indexCount = 0;
for (int i = 0; i < (int)mVertexObjects.size(); i++)
indexCount += mVertexObjects[i].NumIndices;
mIndexCount = indexCount;
indices = new UINT[indexCount];
int numObjects = (int)mVertexObjects.size();
int index = 0;
for (int i = 0; i < numObjects; i++)
{
for (int j = 0; j < (int)mVertexObjects[i].NumIndices; j++)
{
indices[index] = mVertexObjects[i].Indices[j] + (mVertexObjects[i].NumVertices * i);
index++;
}
}
return indices;
}
Be sure to delete the pointer to indices after you're finished with it. Usually it's poor design to allocate memory inside of a function and delete it outside, but this is just for demonstration purposes. Typically you should allocate the index array outside and pass it as a pointer to the function.
One important thing to note is the use of UINT. Most textbooks and articles on the subject allocate smaller index buffers with WORD. Your incremented index array will overflow at index value 65535 using WORD memory allocations. So, if you're rendering a large number of vertices where the index would exceed 16 bits, use UINT and don't forget to switch to DXGI_FORMAT_R32_UINT instead of DXGI_FORMAT_R16_UINT.
E.g.
IASetIndexBuffer(indicesBuffer, DXGI_FORMAT_R32_UINT, 0);

Passing normal data to shader

I have written the simple code to render some objects with DirectX 11.
The position has been passed to shader correctly. However, the normals seem to be lost somewhere. I have changed the shader to see the normals' value as a color (just a debug purpose) and I get the black box (0,0,0 normals of every vertex?), in the right position:
Note that on the right bar I can see my NORMAL values (they are right!), but in the "locals" only position is set and the rest of values are NaN. Why?
The shader:
... //some constants
struct VertexInputType
{
float4 position : POSITION;
float2 tex : TEXCOORD;
float3 normal : NORMAL;
float3 tangent : TANGENT;
//float3 binormal : BINORMAL;
};
struct VS_OUTPUT
{
float4 Pos : SV_POSITION;
float4 worldPos : POSITION;
float2 TexCoord : TEXCOORD;
float3 normal : NORMAL;
float3 tangent : TANGENT;
};
//VS_OUTPUT VS(float4 inPos : POSITION, float2 inTexCoord : TEXCOORD, float3 inNormal : NORMAL, float3 tangent : TANGENT)
VS_OUTPUT VS(VertexInputType input)
{
VS_OUTPUT output;
output.Pos = mul(input.position, WVP);
output.worldPos = mul(input.position, World);
output.normal = input.normal;
return output;
}

During rendering I use:
UINT stride = sizeof(Vertex);
UINT offset = 0;
context->IASetVertexBuffers(0, 1, &buffers->vertexBuffer, &stride, &offset); //set vertex buffer
context->IASetIndexBuffer(buffers->indexBuffer, DXGI_FORMAT_R16_UINT, 0); //set index buffer

//set matrices
DirectX::XMFLOAT4X4 view = camera->getView();
DirectX::XMMATRIX camView = XMLoadFloat4x4(&view);
DirectX::XMFLOAT4X4 projection = camera->getProjection();
DirectX::XMMATRIX camProjection = XMLoadFloat4x4(&projection);
DirectX::XMMATRIX worldViewProjectionMatrix = objectWorldMatrix * camView * camProjection;
//set the constants per object
ConstantBufferStructure constantsPerObject;
constantsPerObject.worldViewProjection = XMMatrixTranspose(worldViewProjectionMatrix);

int start = structure.subsets[i]->getVertexIndexStart();
int count = structure.subsets[i]->getVertexIndexAmmount();

}
And for the shader initializing the :
// Create the vertex shader
hr = device->CreateVertexShader( pVSBlob->GetBufferPointer(), pVSBlob->GetBufferSize(), NULL, &vertexShader );
//create the input layout
VertexLayoutDescirption layoutDescription; //will gives us the data that is corresponding with Vertex structure

Why the normals has not been passed to shader while the position was? What did I miss?

In the shader file try to use float3 normal : TEXCOORD1; or float3 normal : TEXCOORD2; or any Semantic TEXCOORD with any Index instead of float3 normal : NORMAL; in VS_OUTPUT structure,
