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.

Member Function Documentation

int 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 105 of file transformTable.cxx.

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 199 of file transformTable.cxx.

References TypedWritable::complete_pointers().

UpdateSeq TransformTable::get_modified ( Thread current_thread) const
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 92 of file transformTable.I.

int TransformTable::get_num_transforms ( ) const
inline

Returns the number of transforms in the table.

Definition at line 66 of file transformTable.I.

Referenced by DXGraphicsStateGuardian9::begin_draw_primitives().

const VertexTransform * TransformTable::get_transform ( int  n) const
inline

Returns the nth transform in the table.

Definition at line 76 of file transformTable.I.

Referenced by DXGraphicsStateGuardian9::begin_draw_primitives().

bool TransformTable::is_registered ( ) const
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 26 of file transformTable.I.

Referenced by GeomVertexData::set_transform_table().

void TransformTable::register_with_read_factory ( )
static

Tells the BamReader how to create objects of type TransformTable.

Definition at line 167 of file transformTable.cxx.

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

void TransformTable::remove_transform ( int  n)

Removes the nth transform.

Only valid for unregistered tables.

Definition at line 87 of file transformTable.cxx.

void TransformTable::set_transform ( int  n,
const VertexTransform transform 
)

Replaces the nth transform.

Only valid for unregistered tables.

Definition at line 74 of file transformTable.cxx.

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 178 of file transformTable.cxx.

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