Detailed Description ​

cpp
struct Core::TrackedNodeData;

Tracking data for individual nodes involved in a tracking operation.

Instances are held and managed by a MatrixTracker, and referenced by Core nodes when they are tracked. The struct contains common AND specific data for tracked Transforms, Sequences, Cameras and Models.

Public Functions Documentation ​

function TrackedNodeData ​

cpp
inline explicit TrackedNodeData(
    MatrixTracker * tracker
)

function getChildCount ​

cpp
int getChildCount() const

Returns the number of children, what children are and if there are any depends on the particular node type.

Cameras contain sequences, sequences contain transforms, transforms contain tracked matrix objects.

function isSequenceTransform ​

cpp
bool isSequenceTransform() const

Whether this node is both a sequence and a transform (eg. we're using the sequence data as transform)

Public Attributes Documentation ​

variable active ​

cpp
bool active = false;

Whether this node is part of the final tracked interpolated matrix.

variable chain ​

cpp
bool chain = false;

Whether this node forms the top level of the tracked chain.

variable childrenIdxEnd ​

cpp
int childrenIdxEnd = -1;

Index of the last contained sequence, transform or matrix.

See: childrenIdxStart

variable childrenIdxStart ​

cpp
int childrenIdxStart = -1;

Index of the first contained sequence, transform or matrix.

Cameras contain sequences. Sequences contain transforms, however, a sequence itself can BE a transform, in which case it holds indices of matrices, not transforms. The isSequenceTransform() can be used to check for such sequences, a sequence acts as a transform when it has external data plugged into it.

variable interpolating ​

cpp
bool interpolating = false;

Whether the "tracking cursor" is within this node.

variable isInCamera ​

cpp
bool isInCamera = false;

variable mIndex ​

cpp
int mIndex = -1;

Matrix index within the chain, a transform node can represent multiple matrices.

variable modelData ​

cpp
UPtr< TrackedModelData > modelData = nullptr;

Extra model data held for models.

variable modelSubtree ​

cpp
bool modelSubtree = false;

Whether this node is part of the begin sequence subtree.

Meaning it connects to a tracked model but itself is NOT being tracked.

variable progress ​

cpp
float progress {0.f};

Progress within this node.

variable seqID ​

cpp
ID seqID {NIL_ID};

Sequence node id.

variable seqIndex ​

cpp
int seqIndex = -1;

Sequence index within the chain, -1 in model subtree. Valid for sequences and transforms.

variable space ​

cpp
TransformSpace space {TransformSpace::Model};

What stage along the PVM matrix chain this transform represents.

variable tID ​

cpp
ID tID {NIL_ID};

Transform node id.

variable tIndex ​

cpp
int tIndex = -1;

Transform index within the chain, >= 0 indicates transform, a sequence CAN be a transform.

variable tracker ​

cpp
MatrixTracker * tracker;
