Detailed Description

A QGeometry class is used to group a list of QAttribute objects together to form a geometric shape Qt3D is able to render using QGeometryRenderer . Special attribute can be set in order to calculate bounding volume of the shape.

class PySide2.Qt3DRender.Qt3DRender.QGeometry([parent=None])

param parent:

PySide2.Qt3DCore.Qt3DCore.QNode

Constructs a new QGeometry with parent .

PySide2.Qt3DRender.Qt3DRender.QGeometry.addAttribute(attribute)

Parameters:

attribute – PySide2.Qt3DRender.Qt3DRender.QAttribute

Adds an attribute to this geometry.

PySide2.Qt3DRender.Qt3DRender.QGeometry.attributes()

Return type:

Returns the list of attributes in this geometry.

PySide2.Qt3DRender.Qt3DRender.QGeometry.boundingVolumePositionAttribute()

Return type:

PySide2.Qt3DRender.Qt3DRender.QAttribute

Holds the attribute used to compute the bounding volume. The bounding volume is used internally for picking and view frustum culling.

If unspecified, the system will look for the attribute using the name returned by defaultPositionAttributeName .

Parameters:

boundingVolumePositionAttribute – PySide2.Qt3DRender.Qt3DRender.QAttribute

Holds the attribute used to compute the bounding volume. The bounding volume is used internally for picking and view frustum culling.

If unspecified, the system will look for the attribute using the name returned by defaultPositionAttributeName .
