Class RenderVao

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

Vertex array state for geometry that is unique per pipeline. Bind sites probe this with the shader about to be used. The VAOs themselves are created and owned by

, keyed by the shader plus the actual GPU buffer handles involved; this

only memoizes the most recent lookups so repeat draws with the same shader skip the dictionary lookup.

, keyed by the shader plus the actual GPU buffer handles involved; this

public RenderVao(GPUMeshBufferCache meshBuffers, VertexDrawBuffer[] vertexBuffers, int indexBuffer, Material.VsInputSignature inputSignature, string? debugLabel = null)

Parameters

meshBuffers GPUMeshBufferCache

The cache that creates and owns the VAOs.

vertexBuffers VertexDrawBuffer[]

Vertex buffer bindings describing the geometry layout.

indexBuffer int

OpenGL handle of the index buffer, or 0 for non-indexed geometry.

inputSignature Material.VsInputSignature

Material input signature mapping buffer semantics to shader attribute names.

debugLabel string?

Optional label applied to newly created VAOs in debug builds.

RenderVao(GPUMeshBufferCache, string?, int, int, RenderInputLayoutField[], int, VsInputSignature)

Initializes vertex array state for geometry in a single vertex buffer.

public RenderVao(GPUMeshBufferCache meshBuffers, string? debugLabel, int vertexBuffer, int stride, VBIB.RenderInputLayoutField[] inputLayoutFields, int indexBuffer = 0, Material.VsInputSignature inputSignature = default)

Parameters

meshBuffers GPUMeshBufferCache

The cache that creates and owns the VAOs.

debugLabel string?

Optional label applied to newly created VAOs in debug builds.

vertexBuffer int

OpenGL handle of the vertex buffer.

stride int

Size in bytes of a single vertex.

inputLayoutFields VBIB.RenderInputLayoutField[]

Input layout describing the vertex attributes.

indexBuffer int

OpenGL handle of the index buffer, or 0 for non-indexed geometry.

inputSignature Material.VsInputSignature

Optional material input signature mapping buffer semantics to shader attribute names.

Methods

Delete()

Deletes the cached VAOs built from this state's buffers. Call before deleting a buffer that is not tracked by , so no VAO is left referencing it.

public void Delete()

Get(Shader)

Returns the VAO matching the given shader, creating it through the cache on first use.

public int Get(Shader shader)

Parameters

shader Shader

The shader the geometry is about to be rendered with.

Returns

int

The OpenGL VAO handle.
