详细描述

A Qt3DAnimation::QVertexBlendAnimation class implements vertex-blend morphing animation to a target QGeometryRenderer . The QVertexBlendAnimation sets the correct QAttributes 从 morph targets to the target QGeometryRenderer::geometry and calculates interpolator for the current position. Unlike with QMorphingAnimation , where the blending is controller with blend weights, the blending occurs between sequential morph targets. 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.

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 )

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 )

通知程序信号：

void	targetNameChanged (const QString & name )

targetPositions : QVector < float >

Holds the position values of the morph target. Each position in the list specifies the position of the corresponding morph target with the same index. The values must be in an ascending order. Values can be positive or negative and do not have any predefined unit.
