[x3d-public] Texture Coordinate problem with x3dom

Wed Aug 5 12:36:13 PDT 2020

Hello Thomas,

https://www.web3d.org/x3d/content/examples/Vrml2Sourcebook/Chapter18TextureMapping/Figure18_20bTextureCoordinatePizzaSliceX3dom.xhtml

shows the texture correctly.

I think the difference to your webpage test is that you are using html
encoding while the example above is using xhtml encoding.

With html, you have to use explicit closing tags: <TextureCoordinate
..></TextureCoordinate>; for all tags.

Please feel free to use the x3dom-user mailing list, the issue
facility on x3dom github, or x3dom gitter, for further questions.
