Represents a GLTF buffer view.

GLTFBufferView is a data structure representing GLTF a [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.

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].

True if the GLTFBufferView's OpenGL GPU buffer type is an [code]ELEMENT_ARRAY_BUFFER[/code] used for vertex indices (integer constant [code]34963[/code]). False if the buffer type is any other value. See [url=https://github.com/KhronosGroup/glTF-Tutorials/blob/master/gltfTutorial/gltfTutorial_005_BuffersBufferViewsAccessors.md]Buffers, BufferViews, and Accessors[/url] for possible values. This property is set on import and used on export.
