Public Member Functions

virtual TypeHandle force_init_type ()

Detailed Description

Applied to a GeomNode to cause a visible bounding volume to be drawn for this node.

This is generally used only during development to help identify bounding volume issues.

Member Function Documentation

bool ShowBoundsEffect::get_tight ( ) const
inline

Returns true if the "tight" flag was set, meaning the effect should compute and draw the tight bounding-box of the node's vertices every frame.

Definition at line 36 of file showBoundsEffect.I.

void ShowBoundsEffect::register_with_read_factory ( )
static

Tells the BamReader how to create objects of type ShowBoundsEffect.

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

void ShowBoundsEffect::write_datagram ( BamWriter manager,
Datagram dg 
)
virtual

Reimplemented from RenderEffect.
