Unigine::ObjectMeshSkinned Class
| Header: | #include <UnigineObjects.h> |
| Inherits from: | Object |
This class is used to create or modify skinned meshes.
Creating and Playing Animation#
To add the animation to the ObjectMeshSkinned and play it, do the following:
- Set the number of animation layers with setNumLayers(). There is only one layer by default.
- Enable the layer and set the animation weight for blending by calling the setLayer() function.
-
Add the animation *.anim file by using the setLayerAnimationFilePath() function.
- Play the added animation by calling the setLayerFrame() function for each animation layer.
Blending is performed between all layers. The contribution of each layer depends on its weight. Also, you can optionally define single bone transformations by hand, if needed, using either setBoneTransform() or setBoneTransformWithChildren().
Usage Example
The following example shows how to blend 2 different animations assigned to a mesh. In this example we use the mesh and animations from UNIGINE samples located in <UnigineSDK>/data/samples/animation/meshes and <UnigineSDK>/data/samples/animation/animations folders, respectively. Animations are added by using the setLayerAnimationFilePath() function.
Below you'll find an example of using the Component System to access animation assets.
- Create a component for controlling loading of animations and generate a property for it.
- Assign its property to the target controller node.
-
Assign desired animation assets to the parameters of the property by using the Editor.
Assigning animation assets to property parameters via the Editor -
Implement logic of creating a skinned mesh with the specified animations. The complete source code:

Updating Bone Transformations#
Some of the methods require to update the animation data before the renderer makes its update and actually draws the skinned mesh. Such update allows to get the correct result of blending between the frames and layers.
The execution sequence of updating bone transformations is the following:
- Call the method, which sets the update flag. This flag shows that the instance should be updated.
- Update the bone transformations by calling proper functions. These functions check the flag and if the flag is set, they calculate the transformations and set the flag to the default value.
- During the rendering, the engine performs animations and transformations which were calculated on the previous step or recalculates them, if the update flag has been set. If calculations have been performed, the flag is set to the default value.
If you try to update bone transformations before you set the flag to update, functions will not calculate new transformations and the engine doesn't perform them.
When you change the transformation of the bone, you should notify all skinned meshes which use these bone about these transformations to update the mesh. When you change transformations of a bone, skinned mesh instances get the flag to update. When you use the setLayerFrame() function, you set necessary transformations for the specified skinned mesh.
Instancing#
Surfaces of identical skinned meshes which have the same materials assigned to them and the same number of bones attached to their vertices are automatically instanced and drawn in one draw call.
The data buffers for instanced objects that store bones transformations are limited in size; therefore, if skinned meshes have many bones, only a few meshes can populate the instance data buffer to be drawn in one draw call.
Notice
The higher the number of bones and the more bones are attached to one surface, the less robust instancing will be.
Reusing Animations#
Animations from one character can be used for another.
Animation Frame Masks#
Masks are the simplest way of reusing animations, a couple of words about how they work. To each layer of an ObjectMeshSkinned you can assign some animation and based on its frames it will change bone transformations on this layer. You can use masks to choose which components of the animation frame (position, rotation, scale, their combinations, or all of them) are to be used for each particular layer. In case any component is missing in the mask, the corresponding value will be taken from the T-pose.
As an example let's take eyes animation for these two skeletons:
They have absolutely the same bone hierarchy as well as bone names, only the proportions differ. If we use animation for eyes from the left skeleton for the right one, we'll get the following result:
The initial animation has completely changed the proportions of the second skeleton. We can fix it by setting ANIM_FRAME_USES_ROTATION mask to eye bones, and ANIM_FRAME_USES_NONE for the rest of the bones via the setLayerBoneFrameUses() / getLayerBoneFrameUses() methods. Thus, all values except for eyes rotation will be taken from the T-pose :
If the skeletons have different bone names you should first apply retargeting and then use masks. In this case it is not that important to have similar skeletons.
Retargeting#
To reuse animation entirely, both source and target skeletons must have similar bone hierarchy and their T-poses must not significantly differ.
This is acceptable and will work fine:
as we have similar bone hierarchies and all bones have similar bases in T-poses, only the proportions differ, but this proportion is almost uniform for all bones.
But we cannot use the following:
Although the hierarchy looks similar, the T-poses differ and bones have different bases.
These limitations can be ignored if you need to retarget only some subset of the bones (e.g.: retarget bones having different names and then use only masks).
Inverse Kinematics (IK)#
ObjectMeshSkinned supports inverse kinematics (IK) for bone chains (IK chains). Inverse kinematics provide a way to handle joint rotation from the location of an end-effector rather than via direct joint rotation. You provide a location of the effector and the IK Solver attempts to find a rotation so that the final joint coincides with that location as best it can. This can be used to position a character's feet properly on uneven ground, and ensure believable interactions with the world. The tolerance value sets a threshold where the target is considered to have reached its destination position, and when the IK Solver stops iterating.
An IK chain can have an arbitrary length (contain an arbitrary number of bones), it has an auxiliary vector enabling you to control bending direction. You can also set rotation for the last joint of the chain.
Each IK chain has a weight value that can be used to control the impact of the target on the last joint of the chain. This enables you to make smooth transitions from the source animation to required target position of the limb.
To visualize IK chains you can use the following methods: addVisualizeIKChain(), removeVisualizeIKChain(), and clearVisualizeIKChain().
