Detailed Description¶
A
QVertexBlendAnimation
class implements vertex-blend morphing animation to a targetQGeometryRenderer
. TheQVertexBlendAnimation
sets the correctQAttributes
from themorph targets
to the targetgeometry
and calculates interpolator for the current position. Unlike withQMorphingAnimation
, 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 aQParameter
to the used material. All morph targets in the animation should contain the attributes with same names as those in the base geometry.
- class PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation([parent=None])¶
- param parent:
Construct a new
QVertexBlendAnimation
withparent
.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.addMorphTarget(target)¶
- Parameters:
Add new morph
target
at the end of the animation.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.interpolator()¶
- Return type:
float
Holds the interpolator between base and target attributes.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.interpolatorChanged(interpolator)¶
- Parameters:
interpolator – float
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.morphTargetList()¶
- Return type:
Return morph target list.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.removeMorphTarget(target)¶
- Parameters:
Remove morph
target
from the animation.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.setMorphTargets(targets)¶
- Parameters:
targets –
Set morph
targets
to animation. Old targets are cleared.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.setTarget(target)¶
- Parameters:
Holds the target QGeometryRenderer the morphing animation is applied to.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.setTargetName(name)¶
- Parameters:
name – str
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.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.setTargetPositions(targetPositions)¶
- Parameters:
targetPositions –
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.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.target()¶
- Return type:
Holds the target QGeometryRenderer the morphing animation is applied to.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.targetChanged(target)¶
- Parameters:
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.targetName()¶
- Return type:
str
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.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.targetNameChanged(name)¶
- Parameters:
name – str
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.targetPositions()¶
- Return type:
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.
- PySide2.Qt3DAnimation.Qt3DAnimation.QVertexBlendAnimation.targetPositionsChanged(targetPositions)¶
- Parameters:
targetPositions –
