Detailed Description

template<typename ContextType>
class grail::evaluator::BezierSpline< ContextType >

The BezierSpline class -Composite Cubic Bezier Curve.

Template Parameters

ContextType

- Type of evaluated object. By default - ValueTuple(AIEntity, Blackboard).

Constructor & Destructor Documentation

BezierSpline() [1/2]

template<typename ContextType >

grail::evaluator::BezierSpline< ContextType >::BezierSpline ( std::shared_ptr< Evaluator< ContextType >>  childEvaluator, const std::vector< Vector2 > &  points, const std::vector< Vector2 > &  tangents, float  epsilon = 0.001f  )

inline

BezierSpline - Constructor.

Parameters

childEvaluator	- Evaluator which output will be transformed by this curve.
points	- Collection of points. Each two sequenced pair of points describe P0 and P3 of partial spline.
tangents	- Collection of tangent vectors. Each two sequenced pair of vector, added to corresponding points describe P1 and P2 of partial spline.
epsilon	- number representing precision of comparison of two floats

BezierSpline() [2/2]

template<typename ContextType >

grail::evaluator::BezierSpline< ContextType >::BezierSpline ( std::shared_ptr< Evaluator< ContextType >>  childEvaluator, std::vector< Vector2 > &&  points, std::vector< Vector2 > &&  tangents, float  epsilon = 0.001f  )

inline

BezierSpline - Constructor.

Parameters

childEvaluator	- Evaluator which output will be transformed by this curve.
points	- Collection of points. Each two sequenced pair of points describe P0 and P3 of partial spline.
tangents	- Collection of tangent vectors. Each two sequenced pair of vector, added to corresponding points describe P1 and P2 of partial spline.
epsilon	- number representing precision of comparison of two floats
