Detailed Description

Stores the total set of VertexTransforms that the vertices in a particular GeomVertexData object might depend on.

This structure is used for a GeomVertexData set up to compute its dynamic vertices on the graphics card. See TransformBlendTable for one set up to compute its dynamic vertices on the CPU.

Definition at line 38 of file transformTable.h.

Member Function Documentation

◆ add_transform()

size_t TransformTable::add_transform ( const VertexTransform * transform )

Adds a new transform to the table and returns the index number of the new transform.

Only valid for unregistered tables.

This does not automatically uniquify the pointer; if the transform is already present in the table, it will be added twice.

Definition at line 103 of file transformTable.cxx.

◆ complete_pointers()

int TransformTable::complete_pointers	(	TypedWritable **	p_list,
		BamReader *	manager
	)

virtual

Receives an array of pointers, one for each time manager->read_pointer() was called in fillin().

Returns the number of pointers processed.

Reimplemented from TypedWritable.

Definition at line 183 of file transformTable.cxx.

◆ register_with_read_factory()

void TransformTable::register_with_read_factory ( )

static

Tells the BamReader how to create objects of type TransformTable.

Definition at line 156 of file transformTable.cxx.

References BamReader::get_factory(), and Factory< Type >::register_factory().

◆ write_datagram()

void TransformTable::write_datagram	(	BamWriter *	manager,
		Datagram &	dg
	)

virtual

Writes the contents of this object to the datagram for shipping out to a Bam file.

Reimplemented from TypedWritable.

Definition at line 165 of file transformTable.cxx.

References Datagram::add_uint16(), BamWriter::write_cdata(), TypedWritable::write_datagram(), and BamWriter::write_pointer().

Member Data Documentation

◆ get_modified

UpdateSeq TransformTable::get_modified

inline

Returns a sequence number that's guaranteed to change at least when any VertexTransforms in the table change.

(However, this is only true for a registered table. An unregistered table may or may not reflect an update here when a VertexTransform changes.)

Definition at line 61 of file transformTable.h.

◆ get_num_transforms

size_t TransformTable::get_num_transforms

inline

Returns the number of transforms in the table.

Definition at line 50 of file transformTable.h.

◆ get_transform

const VertexTransform * TransformTable::get_transform

inline

Returns the nth transform in the table.

Definition at line 50 of file transformTable.h.

◆ insert_transform

void TransformTable::insert_transform

Inserts a new transform to the table at the given index position.

If the index is beyond the end of the table, appends it to the end. Only valid for unregistered tables.

This does not automatically uniquify the pointer; if the transform is already present in the table, it will be added twice.

Definition at line 63 of file transformTable.h.

◆ is_registered

bool TransformTable::is_registered

inline

Returns true if this table has been registered.

Once it has been registered, the set of transforms in a TransformTable may not be further modified; but it must be registered before it can be assigned to a Geom.

Definition at line 60 of file transformTable.h.

◆ remove_transform

void TransformTable::remove_transform

Removes the nth transform.

Only valid for unregistered tables.

Definition at line 63 of file transformTable.h.

◆ set_transform

void TransformTable::set_transform

Replaces the nth transform.

Only valid for unregistered tables.

Definition at line 63 of file transformTable.h.
