[x3d-public] Texture Coordinate problem with x3dom

Wed Aug 5 11:27:53 PDT 2020

Hi all !

I have a problem with x3dom regarding texture coordinates.

I've reproduced this example (dated 1997!) : 
https://www.web3d.org/x3d/content/examples/Vrml2Sourcebook/Chapter18TextureMapping/Figure18_20bTextureCoordinatePizzaSliceIndex.html

Here's below the webpage test:

<!DOCTYPE html>
<html lang='en'>
<head>
<title>test</title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<script type='text/javascript'

<link rel='stylesheet' type='text/css'

<h1>Test</h1>
<x3d width='500px' height='400px'>
<Scene>
<viewpoint position="1 1 3" orientation="1 0 0 -0.4" 
fieldOfView="1"></viewpoint>
<Shape>
<Appearance><ImageTexture url='"pizza.jpg"'/></Appearance>
<IndexedFaceSet solid='false' texCoordIndex='0, 1, 2, 3, 4, 5' 
coordIndex='0, 1, 2, 3, 4, 5, -1'>
<Coordinate point='0.5 0 0.5, 0.88 0 1.42, 1.06 0 1.33, 1.21 0 1.21, 
1.33 0 1.06, 1.42 0 0.88'/>
<TextureCoordinate point='0.5 0.5, 0.68 0.07, 0.76 0.11, 0.83 0.17, 0.89 
0.24, 0.93 0.32'/>
</IndexedFaceSet>
</Shape>
</Scene>
</x3d>
</body></html>

The problem is that x3dom is simply ignoring the TextureCoordinate, 
resulting a wrong mapping.

The image link working is 
https://www.web3d.org/x3d/content/examples/Vrml2Sourcebook/Chapter18TextureMapping/pizza.jpg

I've tried to put TextureCoordinate before Coordinate, but then it 
fails. I've tried previous versions of x3dom.js, but no luck. I've tried 
on Firefox and Chromium. Thou I've tested the code successfully in 
Titania. But I'd like to use x3dom for the web..

Thank you for you help !
