Detailed Description

D3D11 specialized DrawContext class.

D3D11DrawContext implements the OSD drawing interface with Microsoft(c) DirectX D3D11 API. Some functionality may be disabled depending on compile and run-time driver support.

Contexts interface the serialized topological data pertaining to the geometric primitives with the capabilities of the selected discrete compute device.

Member Function Documentation

static D3D11DrawContext* Create ( Far::PatchTables const *  patchTables, ID3D11DeviceContext *  pd3d11DeviceContext, int  numVertexElements  )

static

Create an D3D11DrawContext from Far::PatchTables.

Parameters

patchTables	A valid set of Far::PatchTables
pd3d11DeviceContext	A device context
numVertexElements	The number of vertex elements

bool SetFVarDataTexture	(	Far::PatchTables const &	patchTables,
		ID3D11DeviceContext *	pd3d11DeviceContext,
		int	fvarWidth,
		FVarData const &	fvarData
	)

Sets face-varying data buffer

Parameters

patchTables	A valid set of Far::PatchTables
pd3d11DeviceContext	A device context
fvarWidth	Total face-varying primvar data width in fvarData
fvarData	Vector containing the face-varying data

Returns

True if the operation was successful

void UpdateVertexTexture ( VERTEX_BUFFER *  vbo, ID3D11DeviceContext *  pd3d11DeviceContext  )

inline

Set vbo as a vertex texture (for gregory patch drawing)

Parameters

vbo	The vertex buffer object to update
pd3d11DeviceContext	A device context
