BoxInterleaved.gltf is not displayed in glTF reference viewer

[cx20]

I tried to display BoxInterleaved.gltf with the latest glTF Reference Viewer.
However, the model does not appear to be displayed.

Perhaps it is because it does not support interleaved format.

Both the glTF and the glb work on http://gltf.ux3d.io and locally (for me) so if it does not work for you locally, it might have to do with your browser, OS or device. What's your setup?

@UX3D-schmithuesen I tested it in the following environment.

OS : Windows 10 / Browser : Chrome 70.0.3538.110 / GPU : Intel HD Graphics 520 (ThinkPad X260)

I checked again with Reference Viewer, but BoxInterleaved.gltf was not displayed.

Box.gltf	BoxInterleaved.gltf

The following warning is displayed on the console. I think that the vertex buffer is not set correctly.

GL_INVALID_OPERATION : glDrawElements: attempt to access out of range vertices in attribute 1

I'm on Firefox and while I don't get any errors, and the front of the cube looks OK, the back of the cube is invisible. @UX3D-schmithuesen, if you rotate the cube around, do you still see the entire thing? AFAIK the output from this gltf should be more or less the same as in Box.gltf, i.e. it should just be a red cube, with all six sides of it displayed. So there is something funky going on. It's running on my integrated Intel HD 620, so it can also be some schenanigns with Intel hardware in particular, but it's probably just that we're indexing into the buffer wrong. Check out the documentation on Mozillas website on Arrays and their typed variants: e.g. FloatArray. IIRC we create a array view into the data buffer, so double check that we've picked the correct type, and that the offset into the data buffer is correct (since the fields are interleaved).

@UX3D-jansson I confirmed it again, and cube could be displayed on Firefox and Edge. I thought it would be the same result as Chrome, so it was unexpected.
