Textures in Web VPython

[John Pedersen]

Hi all,

I had a simple animation made a few months ago that used the 'stucco' texture to emulate the look of the ground. I came back to it a few days ago and when the program runs, the textured objects do not appear.

I am on Google Chrome using trinket. Just to be sure, I checked the sample program on the Glowscript Demos page, and it seems to hang on the 'waitfor' call when loading the textures in. Any suggestions? Thanks!

Strange! Can you provide an URL to a program that exhibits this behavior?

Sure thing! Here is my program (actually using the 'rough' texture, not stucco): https://trinket.io/glowscript/2094069e95

And then the program from the GlowscriptDemos: https://www.glowscript.org/#/user/GlowScriptDemos/folder/Examples/program/Textures-VPython

Your program seems to load for me. If you right click -> inspect -> Console do you see any errors in your browser?

Aha! There are some errors. I didn't consider this, but I use this animation to show my students. The school might have tighter policies for what can be accessed through the program. I ran into a similar problem trying to use a texture for the Moon that I found online. Is there something I can try on my end, or should I go beg for forgiveness from the IT department? Thanks!

Strange. These images should have open CORs policy. Let me poke around and get back to you.

I appreciate it, thank you for the help.
