Detailed Description

BufferDescriptor is a struct which describes buffer elements in interleaved data buffers. Almost all Osd Evaluator APIs take BufferDescriptors along with device-specific buffer objects.

The offset of BufferDescriptor can also be used to express a batching offset if the data buffer is combined across multiple objects together.

  • Note that each element has the same data type (float)
