This class is the base class of the objects in the scene.
+
This class is used to access the bone node parameters in a character skeleton or object.  Retrievable parameters include name, ID, parent node, list of child nodes, and more.  Use [[#Update ( self )|Update]] to get the world-transform values of the bone node for the current point in time.

Description

This class is used to access the bone node parameters in a character skeleton or object. Retrievable parameters include name, ID, parent node, list of child nodes, and more. Use Update to get the world-transform values of the bone node for the current point in time.

Inheritance

RIBase > RIObject > RIAvatar | RICamera | RIParticle | RIProp 
RIObject > RILight > RISpotLight | RIPointLight | RIDirectionalLight

Examples

1 # Get root bone node
2 avatar_list = RLPy.RScene.GetAvatars()
3 avatar = avatar_list[0]
4 skeleton_component = avatar.GetSkeletonComponent()
5 bone_node = skeleton_component.GetRootBone()

Member Functions

GetName ( self )

Get the name of the bone node in a character skeleton or scene object.

Returns

Name of the bone node - str
1 # Get root bone node
2 avatar_list = RLPy.RScene.GetAvatars()
3 avatar = avatar_list[0]
4 skeleton_component = avatar.GetSkeletonComponent()
5 bone_node = skeleton_component.GetRootBone()
6 
7 # Get root bone name
8 bone_name = bone_node.GetName()
9 print(bone_name)

GetID ( self )

Get the ID of the bone node in a character skeleton or scene object.

Returns

ID of the bone node - int
1 # Get root bone node
2 avatar_list = RLPy.RScene.GetAvatars()
3 avatar = avatar_list[0]
4 skeleton_component = avatar.GetSkeletonComponent()
5 bone_node = skeleton_component.GetRootBone()
6 
7 # Get root bone ID
8 bone_id = bone_node.GetID()
9 print(bone_id)

GetParent ( self )

Get the parent bone of the bone node in a character skeleton or scene object. If a parent does not exist, then return None.

See Also: GetChildren

Returns

Parent bone node - RINode
No parent bone node - None
1 # Get root bone node
2 avatar_list = RLPy.RScene.GetAvatars()

7 # Get root bone parent bone
8 parent_bone = bone_node.GetParent()
9 print(parent_bone)

GetChildren ( self )

Get a list of child bones for a bone node in a character skeleton or scene object. If this bone node does not have child bones, then return None.

See Also: GetParent

LocalToWorld ( self, kLocalMatrix )

Convert the local-transform matrix for a bone node in a character skeleton or scene object to world-transform matrix.

See Also: WorldToLocal

Parameters

kLocalMatrix [IN] Character bone node local-transform matrix - RMatrix4

Returns

Bone node world-transform matrix - RMatrix4
 1 # Get root bone node
 2 avatar_list = RLPy.RScene.GetAvatars()
 3 avatar = avatar_list[0]
 4 skeleton_component = avatar.GetSkeletonComponent()
 5 bone_node = skeleton_component.GetRootBone()

 7 # Transfer root bone local transform matrix to world transform matrix
 8 local_transform = bone_node.LocalTransform()
 9 local_matrix = local_transform.Matrix()     
10 local_to_world = bone.LocalToWorld(local_matrix)
11 print(local_to_world)

Update ( self )

Update the Transform Control for a bone node in a character skelecton or scene object and update the scene. After the Update, the Transform Control's key values will reflect the world-transform values of the bone node for the current point in time.
