bool GusdAttribListsBuilder::add	(	const GusdPrimvarInfo &	info,
		const GT_DataArrayHandle &	data
	)

Add an attribute to the appropriate owner's list. Constant attributes may be promoted to the owner configured by setPromoteConstantAttribs(). This may fail if, for example, the data array doesn't match the required number of entries, or if the owner type is not enabled.

GT_AttributeListHandle GusdAttribListsBuilder::buildDetailAttribs ( )

Build the GT_AttributeList for detail attributes. This may return nullptr if there aren't any attributes.

GT_AttributeListHandle GusdAttribListsBuilder::buildPointAttribs ( ) const

Build the GT_AttributeList for point attributes. This may return nullptr if there aren't any attributes.

GT_AttributeListHandle GusdAttribListsBuilder::buildUniformAttribs ( ) const

Build the GT_AttributeList for uniform attributes. This may return nullptr if there aren't any attributes.

GT_AttributeListHandle GusdAttribListsBuilder::buildVertexAttribs ( ) const

Build the GT_AttributeList for vertex attributes. This may return nullptr if there aren't any attributes.

void GusdAttribListsBuilder::enableDetailAttribs ( )

Enable collecting constant / detail attributes.

void GusdAttribListsBuilder::enablePointAttribs ( exint num_points )

Enable collecting point attributes and configure the required number of entries for the arrays.

void GusdAttribListsBuilder::enableUniformAttribs ( exint num_uniform )

Enable collecting uniform attributes and configure the required number of entries for the arrays.

void GusdAttribListsBuilder::enableVertexAttribs ( exint num_vertices )

Enable collecting vertex attributes and configure the required number of entries for the arrays.

void GusdAttribListsBuilder::setPromoteConstantAttribs ( GT_Owner owner )

inline

Configure whether constant attributes should be promoted to another owner. GT_OWNER_DETAIL disables promotion. (Note that GU_MergeUtils may layer promote mismatched detail attribs)
