Is that possible to support 5000 section torus

[wangfei]

Hi GeeXLab experts, GeeXLab is easy to use really, I like that, I tried to create a torus with 5000 section, it seems crash and app disappeared, would  you like to help me to know what's wrong?

Thanks,
Fei

At first, check _geexlab_log.txt in program folder for errors.

Do you want to modify an existing demo? If so, which?

Otherwise start with smaller numbers and increase until you reach the limit.

Thank you Stefan, I am going to load a large obj file, maybe 1GB and bigger, is that possible to load by GeeXLab? Would you like to guide me how to load obj format?

About torus, from log file, there seems not speicial errors, it looks normal:

IDK though how to make your own project in GeexLab itself, but 
MadView3D can load 1GB sized OBJ. files, eg San Miguel from https://casual-effects.com/data/

Still black stuff since the last discussion
