<brief_description>
Represents a glTF buffer view.
</brief_description>
<description>
GLTFBufferView is a data structure representing a glTF [code]bufferView[/code] that would be found in the [code]"bufferViews"[/code] array. A buffer is a blob of binary data. A buffer view is a slice of a buffer that can be used to identify and extract data from the buffer.
Most custom uses of buffers only need to use the [member buffer], [member byte_length], and [member byte_offset]. The [member byte_stride] and [member indices] properties are for more advanced use cases such as interleaved mesh data encoded for the GPU.

<description>
Loads the buffer view data from the buffer referenced by this buffer view in the given [GLTFState]. Interleaved data with a byte stride is not yet supported by this method. The data is returned as a [PackedByteArray].
