ObjectFrame

The ObjectFrame class represents a per-NodeObject animation frame used in the animation system. It contains transformation matrices that are applied to ObjectNode instances and supports operations such as inversion, normalization, multiplication, and interpolation. ObjectFrame instances can be created from an ObjectAnimation at a specific time or from an ObjectLocation or cache index. Multiple ObjectFrame instances can be combined to form an animation graph, which is executed on the GPU by the SceneAnimator.
