Member Function Documentation

void SceneGraphAnalyzer::add_node ( PandaNode node)

Adds a new node to the set of data for analysis.

Normally, this would only be called once, and passed the top of the scene graph, but it's possible to repeatedly pass in subgraphs to get an analysis of all the graphs together.

void SceneGraphAnalyzer::clear ( )

Resets all of the data in the analyzer in preparation for a new run.

Definition at line 62 of file sceneGraphAnalyzer.cxx.

SceneGraphAnalyzer::LodMode SceneGraphAnalyzer::get_lod_mode ( LodMode  lod_mode) const [inline]

Returns the mode in which LODNodes are analyzed.

Definition at line 32 of file sceneGraphAnalyzer.I.

void SceneGraphAnalyzer::set_lod_mode ( LodMode  lod_mode) [inline]

Specifies the mode in which LODNodes are analyzed.

Definition at line 22 of file sceneGraphAnalyzer.I.

void SceneGraphAnalyzer::write ( ostream &  out,
int  indent_level = 0 
) const

Describes all the data collected.
