Detailed Description#

There are 3 types of attributes.

VertexAttribute : used to define data to be read on a per vertex basis

IndexAttribute : used to define vertex indices when indexed draw calls are to be used

DrawIndirectAttribute : used to specify the DrawIndirect buffer to be used when indirect draw calls are to be used

Note

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 defaultPositionAttributeName() as that will ensure your geometry will be compatible with picking and the various materials provided in the Qt3DExtras module.
