My demo_3d_collider.py is working with an error. The window is closing.

Let me see. One sec.

yuanming-hu commented 4 years ago

What's your operating system? I'm on Linux and I failed to reproduce the crash...

PavelBlend commented 4 years ago

Windows 10 64 bit

I also noticed an incorrect display of particles in the demo_2d.py example. I will upload the video now.

Particles sometimes flicker and disappear: https://gfycat.com/familiarpotableaustralianfurseal

Thanks for the info - I reboot into Windows 10 64bit and I can reproduce this issue now. Let me see if I can fix it quickly.

yuanming-hu commented 4 years ago

Unfortunately, this seems a convoluted bug to fix - I have to switch to my work now, and I'll have more time during the weekend to fix this. Sorry about that! I'll try to fix it tomorrow.

PavelBlend commented 4 years ago

No problem.

yuanming-hu commented 4 years ago

The Windows issues should be resolved in taichi v0.5.11. The buildbots are building the Windows releases now. If nothing goes wrong, you should be able to install taichi-nightly==0.5.11 in two hours.

I have to sleep now... See you online tomorrow! :-) Let me know if this solves your issues. Thanks!
