Class GPUMeshBufferCache

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

Caches GPU mesh buffers and vertex array objects for efficient mesh rendering.

public class GPUMeshBufferCache

Inheritance

object ← GPUMeshBufferCache

Constructors

GPUMeshBufferCache(RendererContext)

Initializes a new GPU mesh buffer cache.

public GPUMeshBufferCache(RendererContext rendererContext)

Parameters

rendererContext RendererContext

The renderer context owning this cache.

Properties

EmptyVAO

Gets a lazily created empty vertex array object with no attributes, used for attributeless draws.

public int EmptyVAO { get; }

Property Value

int

QuadIndices

Gets the shared quad index buffer used for rendering quad-based geometry as triangle pairs.

public QuadIndexBuffer QuadIndices { get; }

Property Value

QuadIndexBuffer

VectorOneVertexBuffer

Gets a lazily created vertex buffer containing a single (1, 1, 1, 1) float4, used as a default color attribute.

public int VectorOneVertexBuffer { get; }

Property Value

int

Methods

Clear()

Disposes any cached gpu buffers and frees gpu vertex arrays.

public void Clear()

CreateVertexIndexBuffers(string, VBIB)

Returns cached GPU buffers for the named mesh, uploading them if not yet present.

public GPUMeshBuffers CreateVertexIndexBuffers(string meshName, VBIB vbib)

Parameters

meshName string

Unique name identifying the mesh.

vbib VBIB

Vertex and index buffer data to upload on first use.

Returns

GPUMeshBuffers

The GPU buffers for the mesh.

DeleteVertexIndexBuffers(string)

Deletes and removes the cached GPU buffers for the specified mesh.

public void DeleteVertexIndexBuffers(string meshName)

Parameters

meshName string

Unique name identifying the mesh to delete.

GetVertexArrayObject(string, VertexDrawBuffer[], RenderMaterial, int)

Returns a cached VAO for the given mesh/shader/buffer combination, creating it if necessary.

public int GetVertexArrayObject(string meshName, VertexDrawBuffer[] vertexBuffers, RenderMaterial material, int idxIndex)

Parameters

meshName string

Name of the mesh whose buffers are used.

vertexBuffers VertexDrawBuffer[]

Vertex buffer bindings for the draw call.

material RenderMaterial

Material whose shader determines attribute locations.

idxIndex int

OpenGL handle of the index buffer.

Returns

int

The OpenGL VAO handle.
