Detailed Description

Cache data for rendering mesh UV mapping.

• Contains one or more smaller vertex buffer to support rendering of meshes which are larger than maximum DirectX vertex buffer.
• Also contains supplementary data about edges transparency, neighborhood and patch identification.

HRESULT IRsUVEMeshRenderData::SetViewportData	(	[in] RtUVcoord	panning,
		[in] RtFloat	zoom,
		[in] RtFloat	aspect
	)

Sets the viewport data for rendering.

Parameters:

	panning	[in] Set panning value.
	zoom	[in] Set zoom value.
	aspect	[in] Set aspect.

HRESULT IRsUVEMeshRenderData::BuildFromMesh	(	[in] IRdMesh *	pMesh,
		[in] IUnknown *	pDeviceUnk,
		[in] ReUVTriangulationRenderMode	eRenderMode,
		[in] RtDWORD	dwWireColor,
		[in] RtDWORD	dwActiveUV,
		[in] RtDWORD	dwMaterialIndex,
		[in] RtBool	bRebuildTransparency
	)

Constructs vertex buffers from specified mesh.

Parameters:

	pMesh	[in] Source mesh.
	pDeviceUnk	[in] Pointer to DirectX device.
	eRenderMode	[in] Current edge render mode gained from UVE preferences.
	dwWireColor	[in] Color of UV mapping without transparency information.
	dwActiveSet	[in] Active UV set (0 or 1).
	dwMaterialIndex	[in] Current material index (0xFFFFFFFF if no material defined or all materials are displayed). Used only for filtering UV triangles currently displayed.
	bRebuildTransparency	[in] When true, transparency information is rebuilt (i.e. mesh topology has changed since last render).

HRESULT IRsUVEMeshRenderData::Render

(

[in] IUnknown *

pDeviceUnk

)

Renders mesh vertex buffers on specified device.

Parameters:

pDeviceUnk

[in] Render mesh to specified DirectX device.

HRESULT IRsUVEMeshRenderData::IsEmpty

(

[out, retval] RtBool *

pbEmpty

)

Returns true if there are no vertices in vertex buffers (e.g. built from empty mesh).

Returns:

pbEmpty [out,retval] Returns state of vertex buffers.
