The Entity class provides an abstract base class for all scene graph objects that are considered having a "presence" in the scene, in the sense that it can be considered an actual object with a position and a size (even if infinite or idealised), rather than a grouping. Entities can be partitioned in a space partitioning system and in turn collected by an EntityCollector.

Mesh is an instance of a Geometry, augmenting it with a presence in the scene graph, a material, and an animation state. It consists out of SubMeshes, which in turn correspond to SubGeometries. SubMeshes allow different parts of the geometry to be assigned different materials.

Sprite3D is a 3D billboard, a renderable rectangular area that is always aligned with the projection plane. As a result, no perspective transformation occurs on a Sprite3D object.

TextureProjector is an object in the scene that can be used to project textures onto geometry. To do so, the object's material must have a ProjectiveTextureMethod method added to it with a TextureProjector object passed in the constructor. This can be used for various effects apart from acting like a normal projector, such as projecting fake shadows unto a surface, the impact of light coming through a stained glass window, ...
