详细描述

A class implementing blend-shape morphing animation

A Qt3DAnimation::QMorphingAnimation class implements blend-shape morphing animation to a target QGeometryRenderer 。 QMorphingAnimation sets the correct QAttributes 从 morph targets to the target QGeometryRenderer::geometry and calculates interpolator for the current position. The actual blending between the attributes must be implemented in the material. Qt3DAnimation::QMorphPhongMaterial implements material with morphing support for phong lighting model. The blending happens between 2 attributes - 'base' and 'target'. The names for the base and target attributes are taken from the morph target names, where the base attribute retains the name it already has and the target attribute name gets 'Target' appended to the name. The interpolator can be set as a QParameter to the used material. All morph targets in the animation should contain the attributes with same names as those in the base geometry.

enum QMorphingAnimation:: 方法

This enumeration specifies the morphing method.

常量	值	描述
Qt3DAnimation::QMorphingAnimation::Normalized	0	The blending should use the normalized formula; V' = Vbase * (1.0 - sum(Wi)) + sum[Vi * Wi]
Qt3DAnimation::QMorphingAnimation::Relative	1	The blending should use the relative formula; V' = Vbase + sum[Vi * Wi]

easing : QEasingCurve

Holds the easing curve of the interpolator between morph targets.

访问函数：

QEasingCurve	easing () const
void	setEasing (const QEasingCurve & easing )

通知程序信号：

void	easingChanged (const QEasingCurve & easing )

interpolator : const float

Holds the interpolator between base and target attributes.

访问函数：

float

interpolator () const

通知程序信号：

void	interpolatorChanged (float interpolator )

method : QMorphingAnimation::Method

Holds the morphing method. The default is Relative.

访问函数：

QMorphingAnimation::Method	method () const
void	setMethod (QMorphingAnimation::Method method )

通知程序信号：

void	methodChanged (QMorphingAnimation::Method method )

target : Qt3DRender::QGeometryRenderer *

Holds the target QGeometryRenderer the morphing animation is applied to.

访问函数：

Qt3DRender::QGeometryRenderer *	target () const
void	setTarget (Qt3DRender::QGeometryRenderer * target )

通知程序信号：

void	targetChanged (Qt3DRender::QGeometryRenderer * target )

targetName : QString

Holds the name of the target geometry. This is a convenience property making it easier to match the target geometry to the morphing animation. The name is usually same as the name of the parent entity of the target QGeometryRenderer, but does not have to be.

访问函数：

QString	targetName () const
void	setTargetName (const QString name )

void	targetNameChanged (const QString & name )
