How to: Create a Texture

The simplest way to create a texture is to describe its properties and call the texture creation API. This topic shows how to create a texture.

  1. Fill in a D3D11_TEXTURE2D_DESC structure with a description of the texture parameters.
  2. Create the texture by calling ID3D11Device::CreateTexture2D with the texture description.

This example creates a 256 x 256 texture, with dynamic usage, for use as a shader resource with cpu write access.



D3D11_TEXTURE2D_DESC desc;
desc.Width = 256;
desc.Height = 256;
desc.MipLevels = desc.ArraySize = 1;
desc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
desc.SampleDesc.Count = 1;
desc.Usage = D3D11_USAGE_DYNAMIC;
desc.BindFlags = D3D11_BIND_SHADER_RESOURCE;
desc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE;
desc.MiscFlags = 0;

ID3D11Device *pd3dDevice; // Don't forget to initialize this
ID3D11Texture2D *pTexture = NULL;
pd3dDevice->CreateTexture2D( &desc, NULL, &pTexture );
