tovrmlx3d: glTF does not convert to X3D with tovrmlx3d and neither does .bin. I'm just interested in X3D at this point. about view3dscene HOT 1 CLOSED

Sorry for delayed response. I'm just getting back to my feet after COVID.

1. You need to have both scene.gltf and scene.bin present in the same directory. That is, download http://www.kshell.com/pages/gltfassets/toomuchcoffee/scene.gltf and http://www.kshell.com/pages/gltfassets/toomuchcoffee/scene.bin and place them in the same directory. View3dscene (as any other glTF reader) needs the .bin data, it contains all the per-vertex data (like positions and texture coordinates), without it is impossible to display the 3D content.

   I see the model also uses a texture. Create subdirectory textures and place there https://www.kshell.com/pages/gltfassets/toomuchcoffee/textures/material_0mat_baseColor.jpeg .

   That is how the glTF (from http://www.kshell.com/pages/gltfassets/toomuchcoffee/scene.gltf ) works. In the scene.gltf file, there are links (just trivial relative URLs) that point to scene.bin and textures/material_0mat_baseColor.jpeg. Any glTF reader has to expect these files at respective locations.

   Opening the scene.gltf in view3dscene will now work. I can open it and play the dancing animation happily :)

   

   Converting to X3D tovrmlx3d scene.gltf > new.x3d also works. But be warned: resulting X3D is huge. X3D file size just sucks, with textual encoding, and the way CGE "expands" animation data makes the issue much worse (we add a huge CoordinateInterpolator inside). Resulting X3D in XML encoding is 1.3 GB! (from a few MB of gltf + bin file). For practical purpose, I would not save it to X3D. Fixing this relies on 1. CGE handling skinned animation from glTF better (this will happen definitely soon), 2. X3D having binary encoding like glTF (unknown when it will happen).

2. As an author, alternatively you could have prepared glTF "embedded" (the per-vertex data from .bin, and the texture data, could be embedded within a single .gltf file). That would make it easier to copy the file / open it anywhere. But your scene.gltf wasn't prepared like that.

3. For a normal user (not an author of this file) there is an easier option to open it, to let view3dscene download the linked files:

   • Activate network downloading in view3dscene ("File -> Preferences -> Download Resources from Network")
   • Use view3dscene "Open URL" (Ctrl + L) with http://www.kshell.com/pages/gltfassets/toomuchcoffee/scene.gltf .
   • Give it a few secs, it will automatically download the necessary .bin and texture file then.
