Scene Class Reference

Detailed Description

Represents a 3D scene containing lights and mesh instances.

The Scene class manages the high-level representation of a scene, including its environment, lights, and mesh instances. It handles deferred operations for adding/removing instances across multiple frames.

Parameters
frameIndexThe index of the frame.
Returns
A reference to the SceneFrameData for the frame.
bool haveInstance ( const MeshInstance &  meshInstance) const

Checks if a mesh instance is present in the scene.

Parameters
meshInstanceThe mesh instance to check.
Returns
True if the instance is in the scene, false otherwise.
