Transformhierarchie

Transformhierarchie is a concept used in computer graphics and game development to manage the spatial relationships of objects within a scene. It establishes a parent-child structure where each object, or "node," can have a transform component that defines its position, rotation, and scale relative to its parent. If an object has no parent, its transform is defined relative to the world's origin.

This hierarchical arrangement simplifies complex transformations. When a parent object's transform is modified, all of its children's transforms are automatically updated to reflect this change. This means that moving, rotating, or scaling a parent object will move, rotate, or scale its entire subtree of children accordingly. This is particularly useful for animating complex structures, such as characters with multiple limbs or vehicles with attached parts.

The root of the hierarchy is typically the scene itself or a designated world origin. Objects at the same level in the hierarchy are considered siblings and are not directly influenced by each other's transforms, only by their common parent. This tree-like structure allows for efficient rendering and manipulation of scenes with a large number of interconnected objects, as transformations are calculated and propagated down the hierarchy. Understanding transform hierarchies is fundamental for creating dynamic and interactive 3D environments.
