HRESULT IRsUnknownMeshModifier::GetInputConnectorId

(

CONID *

pConId

)

Get modifier input mesh connector for traversing through mesh modifiers pipeline.

Parameters:

pConId

[in] Input connector ID.

Returns:

Return S_OK if connector is valid.

• Otherwise pipeline traversal will stop assuming that this modifier is editable shape.

HRESULT IRsUnknownMeshModifier::ApplyTransformation	(	[in] IRdMesh *	pMeshIn,
		[out, retval] IRdMesh **	ppMeshOut
	)

Compute mesh directly without caching:

• the result should be computed as if mesh was set to connector defined by GetInputConnectorId.

Remarks:

Method is used for calculating mesh parts for highlights or previews.

Parameters:

	pMeshIn	[in] Input mesh.
	ppMeshOut	[out,retval] Calculated mesh with modifications performed by this modifier applied.

HRESULT IRsUnknownMeshModifier::GetMaximalDependentNeighborhood

(

[out, retval] RtUlong *

pdwNbrs

)

For tools where result depends on neighbor faces:

• This should return max required neighbors, ensuring faces that tools are interested in are calculated correctly.

Returns:

pdwNbrs [out,retval] Number of neighbors to assume for calculations.

HRESULT IRsUnknownMeshModifier::GetOrderingPriority

(

[out, retval] RtFloat *

pfPriority

)

Get the ordering priority for the node

See also:

MeshmodPriority.h for more info.

Returns:

pfPriority [out,retval] Returned priority for node.

HRESULT IRsUnknownMeshModifier::GetModifierFlags

(

RtMeshModifierFlags *

pFlags

)

Return mesh modifier flags that describe the nature of modifier:

• Tools can check if they are compatible with changes that node performs.
