详细描述

A Geometry type is used to group a list of Attribute objects together to form a geometric shape Qt3D is able to render using GeometryRenderer . Special attribute can be set in order to calculate bounding volume of the shape.

特性文档编制

属性 : list < Attribute >

Holds the list of attributes the geometry comprises of.

boundingVolumePositionAttribute : Attribute

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 QAttribute::defaultPositionAttributeName.

[read-only] maxExtent : vector3d

Holds the vertex with the highest x, y, z position values.

[read-only] minExtent : vector3d

Holds the vertex with the lowest x, y, z position values.
