AnimationData

Detailed Description

class AnimationData : public RED::Object

Base data for animation.

@related class RED::AnimationClip, class RED::Quaternion

Animation data is composed of:

  • Position as a 3 components vector;
  • Rotation as a 4 components quaternion;
  • Scale as a 3 components vector.

This class provides functions for blending used in the RED animation system:

An animation data can be converted to a RED::Matrix using the RED::AnimationData::GetMatrix function.

Public Functions

SET_CID (CID_class_REDAnimationData) IMPLEMENT_AS()
AnimationData()

Default constructor.

void SetPosition(const RED::Vector3 &iPosition)

Sets the position.

Parameters:iPosition – Position.
void SetPosition(double iX, double iY, double iZ)

Sets the position from coordinates.

Parameters:
  • iX – Position x coordinate.
  • iY – Position y coordinate.
  • iZ – Position z coordinate.
void SetRotation(const RED::Quaternion &iRotation)

Sets the rotation.

Parameters:iRotation – Rotation as a quaternion.
void SetRotation(double iX, double iY, double iZ, double iW)

Sets the rotation from quaternion values.

Parameters:
void SetScale(const RED::Vector3 &iScale)

Sets the scale.

Parameters:iScale – Scale.
void SetScale(double iX, double iY, double iZ)

Sets the scale from coordinates.

Parameters:
  • iX – Scale x coordinate.
  • iY – Scale y coordinate.
  • iZ – Scale z coordinate.
void SetNeutral()

Sets the neutral transform (no position, rotation or scale).

void Blend(const AnimationData &iData1, const AnimationData &iData2, double iWeight)

Sets the animation data as a blend between two other data.

The blending operation performs interpolations between iData1 and iData2.

Parameters:
  • iData1 – the first data.
  • iData2 – the second data.
  • iWeight – the blending weight between 0 and 1 (0 = iData1, 1 = iData2)
void Add(const AnimationData &iData1, const AnimationData &iData2, double iWeight)

Sets the animation data as an addition of two other data.

The Addition operation performs interpolations between iData1 and iData1 + iData2.

Parameters:
  • iData1 – the first data.
  • iData2 – the second data.
  • iWeight – the blending weight between 0 and 1 (0 = iData1, 1 = iData1 + iData2)
void Sub(const AnimationData &iData1, const AnimationData &iData2, double iWeight)

Sets the animation data as a substraction of two other data.

The Substraction operation performs interpolations between iData1 and iData1 - iData2.

Parameters:
  • iData1 – the first data.
  • iData2 – the second data.
  • iWeight – the blending weight between 0 and 1 (0 = iData1, 1 = iData1 - iData2)
void GetMatrix(RED::Matrix &oMatrix) const

Gets the transform matrix corresponding to the animation data.

Parameters:oMatrix – returned transform matrix.
