Detailed Description

The transformation data class. This class holds all transformation data for each node. This includes local space transforms, local space matrices as well as world space matrices. If for example you wish to get the world space matrices for all nodes, to be used for rendering, you will have to use this class.

Member Enumeration Documentation

ENodeFlags

enum EMotionFX::TransformData::ENodeFlags

Some flags per node, that allow specific optimizations inside EMotion FX.

Enumerator
FLAG_HASSCALE	Has the node a scale factor?

Member Function Documentation

Create()

static TransformData * EMotionFX::TransformData::Create ( )

static

The creation method.

GetSkinningMatrices() [1/2]

MCORE_INLINE AZ::Matrix3x4 * EMotionFX::TransformData::GetSkinningMatrices ( )

inline

Get the skinning matrices (offset from the pose). The size of the returned array is equal to the amount of nodes in the actor or the value returned by GetNumTransforms()

Returns

The array of skinning matrices.

GetSkinningMatrices() [2/2]

MCORE_INLINE const AZ::Matrix3x4 * EMotionFX::TransformData::GetSkinningMatrices ( ) const

inline

Get the skinning matrices (offset from the pose), in read-only (const) mode. The size of the returned array is equal to the amount of nodes in the actor or the value returned by GetNumTransforms()

Returns

The array of skinning matrices.

InitForActorInstance()

void EMotionFX::TransformData::InitForActorInstance

(

ActorInstance *

actorInstance

)

Initialize the transformation data for a given ActorInstance object. This will allocate data for the number of nodes in the actor. You can call this multiple times if needed.

Parameters

actorInstance

The actor instance to initialize for.

Release()

void EMotionFX::TransformData::Release

(

)

Release all allocated memory.

ResetToBindPoseTransformation()

void EMotionFX::TransformData::ResetToBindPoseTransformation ( size_t  nodeIndex )

inline

Reset the local space transform of a given node to its bind pose local space transform.

Parameters

nodeIndex

The node number, which must be in range of [0..GetNumTransforms()-1].

ResetToBindPoseTransformations()

void EMotionFX::TransformData::ResetToBindPoseTransformations ( )

inline

Reset all local space transforms to the local space transforms of the bind pose.
