from panda3d.core import SceneGraphAnalyzer
class SceneGraphAnalyzer

A handy class that can scrub over a scene graph and collect interesting statistics on it.

__init__() → None
__init__(param0: SceneGraphAnalyzer) → None
setLodMode(lod_mode: LodMode) → None

Specifies the mode in which LODNodes are analyzed.

getLodMode(lod_mode: LodMode) → LodMode

Returns the mode in which LODNodes are analyzed.

Return type

LodMode

clear() → None

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

addNode(node: PandaNode) → None

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.

write(out: ostream, indent_level: int) → None

Describes all the data collected.
