class | VertexSlider |
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.

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.

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.

void SliderTable::fillin | ( | DatagramIterator & | scan, |

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.
Referenced by has_slider().
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.)

int SliderTable::get_num_sliders | ( | ) | const [inline] |
Returns the number of sliders in the table.
Definition at line 66 of file sliderTable.I.
const VertexSlider * SliderTable::get_slider | ( | int | n | ) | const [inline] |
Returns the nth slider in the table.
Definition at line 76 of file sliderTable.I.
const SparseArray & SliderTable::get_slider_rows | ( | int | n | ) | const [inline] |
Returns the set of rows (vertices) governed by the nth slider in the table.

bool SliderTable::has_slider | ( | const InternalName * | name | ) | const [inline] |
Returns true if the table has at least one slider by the indicated name, false otherwise.

bool SliderTable::is_empty | ( | ) | const [inline] |
Returns true if the table has no sliders, false if it has at least one.

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.

TypedWritable * SliderTable::make_from_bam | ( | const FactoryParams & | params | ) | [static, protected] |
This function is called by the BamReader's factory when a new object of type SliderTable is encountered in the Bam file.
It should create the SliderTable and extract its information from the file.
