HOW

Object3D initializes with default identity transforms, empty children list, null parent, unit scale, and auto-updating matrices
Scene graph hierarchy methods add, remove, and removeFromParent maintain bidirectional parent-child references and dispatch added/removed events
attach reparents a child node while preserving its absolute world-space transformation matrix
localToWorld and worldToLocal accurately convert 3D coordinates between object local space and root world space
getWorldPosition, getWorldQuaternion, getWorldScale, and getWorldDirection extract decomposed world transforms from matrixWorld
lookAt rotates object orientation such that the negative Z axis points directly towards target coordinates
getObjectById, getObjectByName, and getObjectsByProperty search scene subtrees for matching node identifiers and properties
translateX, translateY, translateZ, and translateOnAxis apply relative positional offsets in local coordinates
clone supports shallow and deep recursive copying and toJSON serializes the scene node hierarchy
