Class VertexAttributeLocations

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

Resolves shader input names and buffer semantics to their .

public static class VertexAttributeLocations

Inheritance

object ← VertexAttributeLocations

Methods

Allocate(IEnumerable<string>, IReadOnlyDictionary<string, int>?)

Gives every attribute of one piece of geometry its location. A mesh attribute keeps its canonical slot. Any other name takes the lowest slot this set leaves free, in name order, so that the shader and the vertex struct declaring the same set both arrive at the same numbers.

A name in pinned keeps the location it was given, and the rest allocate around it. That is how a shader that places an attribute itself, with an explicit layout qualifier, stays consistent with the geometry that feeds it.

public static FrozenDictionary<string, int> Allocate(IEnumerable<string> attributeNames, IReadOnlyDictionary<string, int>? pinned = null)

Parameters

attributeNames IEnumerable<string>

pinned IReadOnlyDictionary<string, int>?

Returns

FrozenDictionary<string, int>

Get(string)

Resolves a shader input name, or -1 if unknown.

public static int Get(string attributeName)

Parameters

attributeName string

Returns

int

Get(string, int)

Resolves a buffer semantic, or -1 if unknown. The fallback when no signature name does.

public static int Get(string semanticName, int semanticIndex)

Parameters

semanticName string

semanticIndex int

Returns

int

GetName(VertexSlot)

The name of a mesh attribute, as its shaders declare it.

public static string GetName(VertexSlot slot)

Parameters

slot VertexSlot

Returns

string

GetSemantic(int)

The buffer semantic a slot is filled from, for describing handbuilt geometry as a layout.

public static (string Name, int Index) GetSemantic(int slot)

Parameters

slot int

Returns

(string Name, int Index)

Resolve(VsInputSignature, RenderInputLayoutField, out string)

Resolves one buffer attribute, or -1 if unknown. The input signature name wins over the attribute's own semantic.

public static int Resolve(Material.VsInputSignature inputSignature, VBIB.RenderInputLayoutField attribute, out string signatureName)

Parameters

inputSignature Material.VsInputSignature

attribute VBIB.RenderInputLayoutField

signatureName string

Returns

int
