Detailed Description

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

This is similar to a TransformTable, but it stores VertexSliders instead of VertexTransforms, and it stores them by name instead of by index number. Also, it is only used when animating vertices on the CPU, since GPU's don't support morphs at this point in time.

Member Function Documentation

◆ add_slider()

int SliderTable::add_slider ( const VertexSlider slider,
const SparseArray rows 
)

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

Only valid for unregistered tables.

Definition at line 130 of file sliderTable.cxx.

References VertexSlider::get_name(), register_with_read_factory(), and SparseArray::set_bit().

Referenced by remove_slider().

◆ complete_pointers()

int SliderTable::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 233 of file sliderTable.cxx.

Referenced by write_datagram().

◆ find_sliders()

const SparseArray & SliderTable::find_sliders ( const InternalName *  name) const
inline

Returns a list of slider indices that represent the list of sliders with the indicated name, or an empty SparseArray if no slider in the table has that name.

Definition at line 101 of file sliderTable.I.

References has_slider().

Referenced by get_slider_rows(), and has_slider().

◆ get_modified()

UpdateSeq SliderTable::get_modified ( Thread current_thread) const
inline

Returns a sequence number that's guaranteed to change at least when any VertexSliders 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 VertexSlider changes.)

Definition at line 143 of file sliderTable.I.

Referenced by is_empty().

◆ get_num_sliders()

int SliderTable::get_num_sliders ( ) const
inline

Returns the number of sliders in the table.

◆ get_slider()

const VertexSlider * SliderTable::get_slider ( int  n) const
inline

Returns the nth slider in the table.

Definition at line 76 of file sliderTable.I.

References get_slider_rows().

References get_modified().

Referenced by has_slider().

◆ is_registered()

bool SliderTable::is_registered ( ) const
inline

Returns true if this table has been registered.

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

Definition at line 26 of file sliderTable.I.

Referenced by is_registered(), and GeomVertexData::set_slider_table().

◆ register_with_read_factory()
