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.
To create a texture
- Fill in a D3D11_TEXTURE2D_DESC structure with a description of the texture parameters.
- 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 );
