SceneGraphAnalyzer(void)

SceneGraphAnalyzer(SceneGraphAnalyzer const&) = default

void 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 clear(void)

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

LodMode get_lod_mode(SceneGraphAnalyzer::LodMode lod_mode) const

Returns the mode in which LODNodes are analyzed.

Describes all the data collected.
