Detailed Description

A QMorphingAnimation class implements blend-shape morphing animation to a target QGeometryRenderer . The QMorphingAnimation sets the correct QAttributes from the morph targets to the target 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.

PySide2.Qt3DAnimation.Qt3DAnimation.QMorphingAnimation.Method

This enumeration specifies the morphing method.

Constant

Description

Qt3DAnimation.QMorphingAnimation.Normalized

The blending should use the normalized formula; V’ = Vbase * (1.0 - sum(Wi)) + sum[Vi * Wi]

Qt3DAnimation.QMorphingAnimation.Relative

The blending should use the relative formula; V’ = Vbase + sum[Vi * Wi]
