Detailed Description

Animated transformation with an underlying keyframe representation.

Constructor & Destructor Documentation

mitsuba::AnimatedTransform::AnimatedTransform ( const Transform & trafo = Transform() )

inline

Create a new animated transformation.

When the transformation is constant (i.e. there are no animation tracks), the supplied parameter specifies the target value.

mitsuba::AnimatedTransform::AnimatedTransform ( Stream * stream )

Unserialized an animated transformation from a binary data stream.

mitsuba::AnimatedTransform::AnimatedTransform ( const AnimatedTransform * trafo )

Copy constructor.

virtual mitsuba::AnimatedTransform::~AnimatedTransform ( )

protectedvirtual

Virtual destructor.

Member Function Documentation

void mitsuba::AnimatedTransform::addTrack ( AbstractAnimationTrack * track )

Append an animation track.

void mitsuba::AnimatedTransform::appendTransform	(	Float	time,
		const Transform &	trafo
	)

Convenience function, which appends a linear transformation to the track.

Internally, a polar decomposition is used to split the transformation into scale, translation, and rotation, which are all separately interpolated.

Remarks: Remember to run sortAndSimplify() after adding all transformations.

void mitsuba::AnimatedTransform::collectKeyframes ( std::set< Float > & result ) const

Return the used keyframes as a set.

const Transform& mitsuba::AnimatedTransform::eval ( Float t ) const

inline

Compute the transformation for the specified time value.

Note that the returned reference leads to a thread-local cache. This means that it will become invalidated at the next call to this function.

AbstractAnimationTrack* mitsuba::AnimatedTransform::findTrack ( AbstractAnimationTrack::EType type )

Find a track of the given type.

const AbstractAnimationTrack* mitsuba::AnimatedTransform::findTrack ( AbstractAnimationTrack::EType type ) const

Find a track of the given type.

virtual const Class* mitsuba::AnimatedTransform::getClass ( ) const

virtual

Retrieve this object's class.

Reimplemented from Object.

AABB mitsuba::AnimatedTransform::getSpatialBounds ( const AABB & aabb ) const

Compute the spatial bounds of a transformed (static) AABB.

AABB1 mitsuba::AnimatedTransform::getTimeBounds ( ) const

Return the extents along the time axis.

AbstractAnimationTrack* mitsuba::AnimatedTransform::getTrack ( size_t idx )

inline

Look up one of the tracks by index.

const AbstractAnimationTrack* mitsuba::AnimatedTransform::getTrack ( size_t idx ) const

inline

Look up one of the tracks by index (const version)

size_t mitsuba::AnimatedTransform::getTrackCount ( ) const

inline

Return the number of associated animation tracks.

AABB mitsuba::AnimatedTransform::getTranslationBounds ( ) const

Return an axis-aligned box bounding the amount of translation.

void mitsuba::AnimatedTransform::prependScale ( const Vector & scale )

Prepend a scale transformation to the transform (this is often useful)

void mitsuba::AnimatedTransform::serialize ( Stream * stream ) const

Serialize to a binary data stream.

void mitsuba::AnimatedTransform::sortAndSimplify ( )

Sort all animation tracks and remove unnecessary data (for user-provided input)

std::string mitsuba::AnimatedTransform::toString ( ) const

virtual

Return a human-readable string description.

Reimplemented from Object.
