Class NodeAnimationChannel

Describes the animation of a single node. The name specifies the bone/node which is affected by this animation chanenl. The keyframes are given in three separate seties of values, one for each position, rotation, and scaling. The transformation matrix is computed from these values and replaces the node's original transformation matrix at a specific time.

This means all keys are absolute and not relative to the bone default pose. The order which the transformations are to be applied is scaling, rotation, and translation (SRT).

Keys are in chronological order and duplicate keys do not pass the validation step. There most likely will be no negative time values, but they are not forbidden.

Syntax

public sealed class NodeAnimationChannel : IMarshalable<NodeAnimationChannel, AiNodeAnim>

Constructors

NodeAnimationChannel()

Constructs a new instance of the NodeAnimationChannel class.

Declaration

public NodeAnimationChannel()

Properties

HasPositionKeys

Gets if this animation channel contains position keys.

Declaration

public bool HasPositionKeys { get; }

Property Value

Type	Description
bool

HasRotationKeys

Gets if the animation channel contains rotation keys.

Declaration

public bool HasRotationKeys { get; }

Property Value

Type	Description
bool

HasScalingKeys

Gets if the animation channel contains scaling keys.

Declaration

public bool HasScalingKeys { get; }

Property Value

Type	Description
bool

NodeName

Gets or sets the name of the node affected by this animation. It must exist and it must be unique.

Declaration

public string NodeName { get; set; }

Property Value

Type	Description
string

PositionKeyCount

Gets the number of position keys in the animation channel.

Declaration

public int PositionKeyCount { get; }

Property Value

Type	Description
int

PositionKeys

Gets the position keys of this animation channel. Positions are specified as a 3D vector. If there are position keys, there should also be -at least- one scaling and one rotation key.

Declaration

public List<VectorKey> PositionKeys { get; }

Property Value

Type	Description
List<VectorKey>

PostState

Gets or sets how the animation behaves after the last key was processed. By default the original transformation matrix of the affected node is taken.

Declaration

public AnimationBehaviour PostState { get; set; }

Property Value

Type	Description
AnimationBehaviour

PreState

Gets or sets how the animation behaves before the first key is encountered. By default the original transformation matrix of the affected node is used.

Declaration

public AnimationBehaviour PreState { get; set; }

Property Value

Type	Description
AnimationBehaviour

RotationKeyCount

Gets the number of rotation keys in the animation channel.

Declaration

public int RotationKeyCount { get; }

Property Value

Type	Description
int

RotationKeys

Gets the rotation keys of this animation channel. Rotations are given as quaternions. If this exists, there should be -at least- one scaling and one position key.

Declaration

public List<QuaternionKey> RotationKeys { get; }

Property Value

Type	Description
List<QuaternionKey>

ScalingKeyCount

Gets the number of scaling keys in the animation channel.

Declaration

public int ScalingKeyCount { get; }

Property Value

Type	Description
int

ScalingKeys

Gets the scaling keys of this animation channel. Scalings are specified in a 3D vector. If there are scaling keys, there should also be -at least- one position and one rotation key.

Declaration

public List<VectorKey> ScalingKeys { get; }

Property Value

Type	Description
List<VectorKey>

Methods

FreeNative(nint, bool)

Frees unmanaged memory created by ToNative(nint, out Native).

Declaration

public static void FreeNative(nint nativeValue, bool freeNative)

Parameters

Type	Name	Description
nint	nativeValue	Native value to free
bool	freeNative	True if the unmanaged memory should be freed, false otherwise.

Implements

IMarshalable<Managed, Native>
