QMorphingAnimation

PyQt5.Qt3DAnimation.QMorphingAnimation

Inherits from QAbstractAnimation.

Description

A class implementing blend-shape morphing animation.

A QMorphingAnimation class implements blend-shape morphing animation to a target QGeometryRenderer. The QMorphingAnimation sets the correct QAttribute from the QMorphTarget 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.

Enums

Method

This enumeration specifies the morphing method.

Member	Value	Description
Normalized	0	The blending should use the normalized formula; V’ = Vbase * (1.0 - sum(Wi)) + sum[Vi * Wi]
Relative	1	The blending should use the relative formula; V’ = Vbase + sum[Vi * Wi]
