Struct VertexElement

Namespace
Stride.Graphics
Assembly
Stride.Graphics.dll

A description of a single element for the input-assembler stage. This structure is related to Direct3D11.InputElement.

[DataContract]
[DataSerializer(typeof(VertexElement.Serializer))]
public struct VertexElement : IEquatable<VertexElement>
Implements

Remarks

Because Direct3D11.InputElement requires to have the same VertexBufferLayout.SlotIndex, VertexBufferLayout.VertexClassification and VertexBufferLayout.instanceDataStepRate, the VertexBufferLayout structure encapsulates a set of VertexElement for a particular slot, classification and instance data step rate. Unlike the default Direct3D11.InputElement, this structure accepts a semantic name with a postfix number that will be automatically extracted to the semantic index.

Constructors

VertexElement(string, PixelFormat)

Initializes a new instance of the VertexElement struct.

public VertexElement(string semanticName, PixelFormat format)

Parameters

semanticName string

Name of the semantic.

format PixelFormat

The format.

Remarks

If the semantic name contains a postfix number, this number will be used as a semantic index.

VertexElement(string, int, PixelFormat, int)

Initializes a new instance of the VertexElement struct.

public VertexElement(string semanticName, int semanticIndex, PixelFormat format, int alignedByteOffset = -1)

Parameters

semanticName string

Name of the semantic.

semanticIndex int

Index of the semantic.

format PixelFormat

The format.

alignedByteOffset int

The aligned byte offset.

Fields

AppendAligned

Returns a value that can be used for the offset parameter of an InputElement to indicate that the element should be aligned directly after the previous element, including any packing if neccessary.

public const int AppendAligned = -1

Field Value

int

A value used to align input elements.

Properties

AlignedByteOffset

Optional. Offset (in bytes) between each element. Use D3D11_APPEND_ALIGNED_ELEMENT for convenience to define the current element directly after the previous one, including any packing if necessary.

public int AlignedByteOffset { get; }

Property Value

int

Format

The data type of the element data. See SharpDX.DXGI.Format.

public PixelFormat Format { get; }

Property Value

PixelFormat

SemanticAsText

The HLSL semantic associated with this element in a shader input-signature.

public string SemanticAsText { get; }

Property Value

string

SemanticIndex

The semantic index for the element. A semantic index modifies a semantic, with an integer index number. A semantic index is only needed in a case where there is more than one element with the same semantic. For example, a 4x4 matrix would have four components each with the semantic name 

matrix

, however each of the four component would have different semantic indices (0, 1, 2, and 3).

public int SemanticIndex { get; }

Property Value

int

SemanticName

The HLSL semantic associated with this element in a shader input-signature.

public string SemanticName { get; }

Property Value

string
