Detailed Description

Rotate an object around an axis.

Inherits Animation.

Constructor & Destructor Documentation

Rotation() [1/2]

Rotation::Rotation ( )

default

Default constructor.

Rotation() [2/2]

Rotation::Rotation	(	const glm::vec3 &	axis,
		float	speed,
		Frame	frame
	)

Setup a rotation animation.

Parameters

axis	the rotation axis
speed	the animation speed
frame	the animation frame

Member Function Documentation

apply() [1/2]

glm::mat4 Rotation::apply ( const glm::mat4 &  m, double  fullTime, double  frameTime  )

overridevirtual

Apply the animation transformation to the input matrix.

Parameters

m	the matrix to transform
fullTime	the time elapsed since the beginning of the rendering loop
frameTime	the time elapsed since last frame

Returns

the transformed matrix.

Implements Animation.

apply() [2/2]

glm::vec4 Rotation::apply ( const glm::vec4 &  v, double  fullTime, double  frameTime  )

overridevirtual

Apply the animation transformation to the input vector.

Parameters

v	the vector to transform
fullTime	the time elapsed since the beginning of the rendering loop
frameTime	the time elapsed since last frame

Returns

the transformed matrix.

Implements Animation.

decode()

bool Rotation::decode

(

const KeyValues &

params

)

Setup rotation animation parameters from a key-value tuple. The expected format is as follows:

rotation: speed frame axisX,axisY,axisZ

(where frame is one of 'world' or 'model').

Parameters

params

the parameters tuple

Returns

decoding status

encode()

KeyValues Rotation::encode ( ) const

overridevirtual

Generate a key-values representation of the animation. See decode for the keywords and layout.

Returns

a tuple representing the animation.

Reimplemented from Animation.
