Open Reality
UI element
The User Interface classes of Open Reality are derived from FBVirsualComponent, These are both components, can be used in custom layouts.
Skeleton
The FBModelSkeleton inherited from FBModel, it’s mean the Root Bone of a Skeleton, It’s contains the:
· Children Bone List
· The Local & global info of this bone.
Every bone node in MB is a FBModelSkeleton, so we can use it to create the Onyx::Skeleton component and got the init info of the skeleton.
Animation
The FBModelSkeleton has an FBPropertyAnimationNode. FBAnimationNode keeps the movement info.
Every node (including Bone) in MotionBuilder, has a Translation FBAnimationNode, a Rotation FBAnimationNode, a Scale FBAnimationNode. Those FBAnimationNodes are animatable which means it record the animation information, when the key frame of the bone is changed, those FBAnimationNode means the bone’s transform at current time:
· “Lcl Transalation” FBAnimationNode: The local position of the node’s animation track.
· “Lcl Rotation” FBAnimationNode: The local rotation value of the node’s animation track.
· “Lcl Scale” FBAnimationNode: The scaling value of the node’s animation track.
