Detailed Description

Calculates transformations for a given timestamp from a set of animation tracks.

Not directly useful, better use the AnimPlayer class.

Constructor & Destructor Documentation

AnimEvaluator()

AnimEvaluator::AnimEvaluator

(

const aiAnimation *

pAnim

)

Constructor on a given animation.

The animation is fixed throughout the lifetime of the object.

Parameters

pAnim

The animation to calculate poses for. Ownership of the animation object stays at the caller, the evaluator just keeps a reference to it as long as it persists.

~AnimEvaluator()

AnimEvaluator::~AnimEvaluator

(

)

The class destructor.

Evaluate()

void AnimEvaluator::Evaluate

(

double

pTime

)

Evaluates the animation tracks for a given time stamp.

The calculated pose can be retrieved as a array of transformation matrices afterwards by calling GetTransformations().

Parameters

pTime

The time for which you want to evaluate the animation, in seconds. Will be mapped into the animation cycle, so it can be an arbitrary value. Best use with ever-increasing time stamps.

GetTransformations()

const std::vector<aiMatrix4x4>& AssimpView::AnimEvaluator::GetTransformations ( ) const

inline

Returns the transform matrices calculated at the last Evaluate() call.

The array matches the mChannels array of the aiAnimation.
