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.

References _num_nodes, and _num_nodes_with_attribs.

void SceneGraphAnalyzer::clear (  void   ) 
 

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

void SceneGraphAnalyzer::collect_statistics (  Texture *  texture  )  [private]
 

Recursively visits each node, counting up the statistics.
