Detailed Description

Layout for node attributes sampled at signed ancestor/current/descendant offsets.

The layout is node-major: for a given node, all requested sample positions are stored contiguously. NUM_ATTRIBUTES therefore counts the number of (attribute, sampleOffset) entries associated with each node.

Constructor & Destructor Documentation

NodeAttributeSampleLayout()

mmcfilters::NodeAttributeSampleLayout::NodeAttributeSampleLayout ( std::unordered_map< NodeAttributeSampleKey, int > &&  map )

inline

Constructs a layout from an already validated offset map.

The constructor takes ownership of map and derives the per-node stride from its final size.

Parameters

map	Mapping used to initialize the layout.

Definition at line 48 of file AttributeNames.hpp.

Member Function Documentation

create()

static NodeAttributeSampleLayout mmcfilters::NodeAttributeSampleLayout::create ( int  samplingRadius, const std::vector< Attribute > &  attributes  )

inlinestatic

Builds the canonical dense layout for offsets in [-samplingRadius, samplingRadius].

Parameters

samplingRadius	Maximum ancestor/descendant sample offset.
attributes	Attributes requested by the operation.

Returns

The resulting canonical dense sampled layout.

Definition at line 58 of file AttributeNames.hpp.

getIndex() [1/2]

int mmcfilters::NodeAttributeSampleLayout::getIndex ( Attribute  attribute, int  sampleOffset  ) const

inline

Returns the per-node offset associated with (attribute, sampleOffset).

Parameters

attribute	Attribute requested by the operation.
sampleOffset	Signed sample coordinate.

Returns

The per-node offset associated with the key.

Definition at line 79 of file AttributeNames.hpp.

getIndex() [2/2]

int mmcfilters::NodeAttributeSampleLayout::getIndex ( NodeAttributeSampleKey  sampleKey ) const

inline

Returns the per-node offset associated with a composite sample key.

Parameters

sampleKey

Composite sampled-attribute key.

Returns

The per-node offset associated with the key.

Definition at line 89 of file AttributeNames.hpp.

linearIndex() [1/2]

int mmcfilters::NodeAttributeSampleLayout::linearIndex ( int  nodeIndex, Attribute  attribute, int  sampleOffset  ) const

inline

Returns the linear index in the flat buffer for a given node and sampled attribute.

Parameters

nodeIndex	Index.
attribute	Attribute requested by the operation.
sampleOffset	Signed sample coordinate.

Returns

The linear index in the flat buffer.

Definition at line 100 of file AttributeNames.hpp.

linearIndex() [2/2]

int mmcfilters::NodeAttributeSampleLayout::linearIndex ( int  nodeIndex, NodeAttributeSampleKey  sampleKey  ) const

inline

Convenience overload taking a NodeAttributeSampleKey.

Parameters

nodeIndex	Index.
sampleKey	Composite sampled-attribute key.

Returns

Value returned by the convenience overload.

Definition at line 111 of file AttributeNames.hpp.

toString() [1/2]

static std::string mmcfilters::NodeAttributeSampleLayout::toString ( Attribute  attribute, int  sampleOffset  )

inlinestatic

Returns a serialized label for an attribute at a sample offset.

Parameters

attribute	Attribute requested by the operation.
sampleOffset	Signed sample coordinate.

Returns

The canonical serialized label.

Definition at line 132 of file AttributeNames.hpp.

toString() [2/2]

static std::string mmcfilters::NodeAttributeSampleLayout::toString ( NodeAttributeSampleKey  sampleKey )

Returns a human-readable label for a composite key.

Parameters

sampleKey

Composite sampled-attribute key.

Returns

A human-readable label for a composite key.
