There are 3 types of attributes.
注意: when an attribute is of type DrawIndirectAttribute , only count, stride and offset are relevant.
When providing your own attributes, it may make sense to name your attribute using helpers such as QAttribute::defaultPositionAttributeName () as that will ensure your geometry will be compatible with picking and the various materials provided in the Qt3DExtras 模块。
