Detailed Description

[AI] Represents a Level of Detail (LOD) object for rendering, implemented with a mesh builder and supporting bitwise flag operations.

[AI] ViewLOD handles a group of polygons (LODObject) at a specific detail level, utilizing a Tgl::MeshBuilder for 3D mesh construction. It provides methods for average polygon area estimation and custom flag manipulation, intended for optimizing rendering performance based on distance or importance. The flags in m_unk0x08 are manipulated to affect the object's LOD state.
