cgltf_image::buffer_view::data is null

[Trider12]

I'm loading some glb files and cgltf_image::buffer_view::data is null:

I'm able to get the data by doing:

void* data = texture->image->buffer_view->buffer->data + texture->image->buffer_view->offset;

But this feels like not the intended way of doing this.

There is actually a comment in the definition of cgltf_buffer_view about this:

	void* data; /* overrides buffer->data if present, filled by extensions */

And then there is a helper function which does exactly what you are doing: cgltf_buffer_view_data(). It doesn't seem to be exposed externally though. Maybe we should do that. It would help you, correct?

Ah, I saw that comment, but still miss-interpreted the purpose of the cgltf_buffer_view::data field. I feel that the naming is a bit confusing, but understand that altering it is a breaking change, so is not possible.

But I did actually end up writing a function identical to cgltf_buffer_view_data() myself, so maybe exposing it is a good idea.
