Member Function Documentation

template<class Mesh , class Mod >

DrawModes::DrawMode ACG::SceneGraph::StatusNodeT< Mesh, Mod >::availableDrawModes ( ) const

virtual

Return a list of available draw modes for this node: should be OR'ed from the items of the enum DrawModeIDs.

Reimplemented from ACG::SceneGraph::ACG::SceneGraph::BaseNode.

Definition at line 110 of file StatusNodesT.cc.

template<class Mesh , class Mod >

void ACG::SceneGraph::StatusNodeT< Mesh, Mod >::boundingBox ( Vec3d &  , Vec3d &    )

virtual

Compute the bounding box of this node and update the values _bbMin and _bbMax accordingly. Do not initialize _bbMin and _bbMax since they may already store values of previous nodes' bounding box computation.

Reimplemented from ACG::SceneGraph::ACG::SceneGraph::BaseNode.

Definition at line 97 of file StatusNodesT.cc.

template<class Mesh , class Mod >

void ACG::SceneGraph::StatusNodeT< Mesh, Mod >::update_cache ( )

private

build/update cache of active vertices/edges/faces. This function automatically enables caching.
