3d rendering Issue: #182
Description
Intent: We are trying only to display 3d objects with their default parameters
Output: But it only showing a black screen after execution.
System: Linux operating system: Fedora Linux 39 (Workstation Edition), browser: Firefox version 120
from vpython import *
from sys import exit
def menu():
print('1. Curve')
print('2. Sphere')
print('3. Cone')
print('4. Arrow')
print('5. Rings')
print('6. Cylinder')
ch = "y"
while ch != "n":
scene = canvas()
menu()
choice = int(input('Enter choice: '))
if choice == 1:
curve()
elif choice == 2:
sphere()
elif choice == 3:
cone()
elif choice == 4:
arrow()
elif choice == 5:
ring()
elif choice == 6:
cylinder()
else:
print('Invalid choice')
ch = input('Do you want to continue (y/n)? ').lower()
scene.delete()
exit()Tried to resolve this issue: By passing some parameters, by redrawing the screen, updating the screen etc.

What Python are you using? From the installation instructions at vpython.org: The vpython module currently works with Python versions 3.8, 3.9, and 3.10. (We are working on a release for 3.11)

Try running this Web VPython program: tinyurl.com/vporbit. If it fails, it could be that WebGL2 is not available in your browser. Go to https://get.webgl.org/
You should see a rotating wire frame box.
Next, go to https://browserleaks.com/webgl
and report whether both WebGL and WebGL2 are checked True.

I also have the same problem, I have some smartphone devices, on the device with WebGL_Unmasked_Renderer value as Mali-..., it does not display block, spheres, text,... but only displays the trajectory (see attached video https://files.catbox.moe/qyluvx.mp4), it works normally on the devices with WebGL_Unmasked_Renderer: ANGLE

@BruceSherwood could you help to check my above comment?
BruceSherwood commentedon Oct 1, 2024
I know nothing about the issues you mention. I'll mention that you might run https://get.webgl.org/webgl2/ to see whether your device does or doesn't support WebGL2 in the browser; VPython uses WebGL2.

@BruceSherwood My phone has WebGL2 supported, there is some kind of graphics type can not be rendered like text, box, sphere,... Its happens on both Chrome, Firefox. I have some other devices which also happens are has WebGL_Unmasked_Renderer: Mali-xyz

Sorry, but I am unable to debug the problems you have encountered. I've never heard of anyone else seeing the problems you see.

I am currently facing the same issue, curves display but that is all, unless I use another browser
