XG_BIND_FLAG Enumeration

Identifies how to bind a resource to the pipeline.

Syntax

enum XG_BIND_FLAG
{
    XG_BIND_VERTEX_BUFFER = 0x1L,
    XG_BIND_INDEX_BUFFER = 0x2L,
    XG_BIND_CONSTANT_BUFFER = 0x4L,
    XG_BIND_SHADER_RESOURCE = 0x8L,
    XG_BIND_STREAM_OUTPUT = 0x10L,
    XG_BIND_RENDER_TARGET = 0x20L,
    XG_BIND_DEPTH_STENCIL = 0x40L,
    XG_BIND_UNORDERED_ACCESS = 0x80L,
    XG_BIND_DECODER = 0x200L,
    XG_BIND_VIDEO_ENCODER = 0x400L
};  

Constants

Constant	Description
XG_BIND_VERTEX_BUFFER	Bind a buffer as a vertex buffer to the input-assembler stage.
XG_BIND_INDEX_BUFFER	Bind a buffer as an index buffer to the input-assembler stage.
XG_BIND_CONSTANT_BUFFER	Bind a buffer as a constant buffer to a shader stage; this flag may NOT be combined with any other bind flag.
XG_BIND_SHADER_RESOURCE	Bind a buffer or texture to a shader stage.
XG_BIND_STREAM_OUTPUT	Bind an output buffer for the stream-output stage.
XG_BIND_RENDER_TARGET	Bind a texture as a render target for the output-merger stage.
XG_BIND_DEPTH_STENCIL	Bind a texture as a depth-stencil target for the output-merger stage.
XG_BIND_UNORDERED_ACCESS	Bind an unordered access resource.
XG_BIND_DECODER	Set this flag to indicate that a 2D texture is used to receive output from the decoder API. The common way to create resources for a decoder output is by calling the ID3D11Device::CreateTexture2D method to create an array of 2D textures. However, you cannot use texture arrays that are created with this flag in calls to ID3D11Device::CreateShaderResourceView. Direct 3D 11 Note This value is not supported until Direct3D 11.1.
XG_BIND_VIDEO_ENCODER	Set this flag to indicate that a 2D texture is used to receive input from the video encoder API. The common way to create resources for a video encoder is by calling the ID3D11Device::CreateTexture2D method to create an array of 2D textures. However, you cannot use texture arrays that are created with this flag in calls to ID3D11Device::CreateShaderResourceView. Direct 3D 11 Note This value is not supported until Direct3D 11.1.

Remarks

XG_BIND_FLAG is similar to D3D11_BIND_FLAG.

In general, binding flags can be combined using a logical OR (except the constant-buffer flag); however, you should use a single flag to allow the device to optimize the resource usage.

This enumeration is used by a:

• Buffer description when creating a buffer.
• Texture description when creating a texture (see XG_TEXTURE1D_DESC or XG_TEXTURE2D_DESC or XG_TEXTURE3D_DESC).

A shader-resource buffer is not a constant buffer; rather, it is a texture or buffer resource that is bound to a shader, that contains texture or buffer data (it is not limited to a single element type in the buffer). A shader-resource buffer is created with the XG_BIND_SHADER_RESOURCE flag and is bound to the pipeline using one of these APIs: ID3D11DeviceContext::GSSetShaderResources, ID3D11DeviceContext::PSSetShaderResources, or ID3D11DeviceContext::VSSetShaderResources.
