Detailed Description#
A
QGeometry
class is used to group a list ofQAttribute
objects together to form a geometric shape Qt3D is able to render using Qt3DCore::QGeometryRenderer. Special attribute can be set in order to calculate bounding volume of the shape.Note
Properties can be used directly when
from __feature__ import true_property
is used or via accessor functions otherwise.- property boundingVolumePositionAttributeᅟ: 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
.See also
