Data issue identified by CGE, hundred of similar error reports in Castle Model Viewer
coderextreme opened this issue · comments
You've probably seen this before. This example has data errors as reported by CGE and Castle Model Viewer 5.0 release (CMV). My only complaint is that there's literally hundreds of errors as the animation plays in CMV (fortunately just one in CGE, with my drag and drop program--no animation). Help! I'm not sure you need to do anything about this. Close as a data issue is probably your best bet. The errors have been reported to responsible parties.
Here are the errors from CMV (some of them):
X3D: Invalid number of items in an attribute array for shape "Joe_Humanoid/Joe_Kick/Joe_Shape/IndexedFaceSet(Joe_skin_IndexedFaceSet)": Invalid index: 9, but we have 4 items in 2D texture coordinates

The model is invalid, and it should fail in X3D browsers (because it is undefined what author wants, and trying to "guess" what the author wants in this case would be bad -- various authors could want different things).
This specific model has been discussed a number of times on x3d-public mailing list. See e.g. "HAnim sample failing in X3DOM, error in view3dscene, additional tests". It's an obvious error, castle-model-viewer message is right (BTW, please don't shorten it to CMV, I'm afraid people will not know what it means). It's not easy for us to make this message less often, due to the fact that these things may change each frame.
The model has 4 texture coordinates (8 floats below):
<TextureCoordinate point='0 0 0.5 0.5 0.5 0 0 0.5'/>
but this array is accessed using coordIndex
(since there's no texCoordIndex
) which has values outside of 0..3 range:
<IndexedFaceSet DEF='Joe_skin_IndexedFaceSet' coordIndex='0 9 5 -1 0 7 9 -1 0 5 1
...
The author should fix the model. How? It depends on what the author wants. Applying a texture means you need to tell what texture coordinate should be used to display each vertex. I don't know how the author wanted to map this texture.
