opengl - Should primitives be centered in a 3d engine? -


so, i'm adding physics game engine right , physics engine expects vertices of primitive distributed around 0,0,0. primitive cubes vertice positions range 0 1 in every dimension. should center cubes around 0,0,0 or shift vertices when giving them physics engine , when reading position of rigidbody ?

depends on physics engine, it's easiest work if physics system can assume object's center of mass @ 0,0,0. cube primitives, if think rotating , scaling them, should come conclusion 0,0,0 center convenient operations well.

python - Django-cities exits with "killed" -

i trying install django-cities on server 500mb ram. whenever run: manage.py cities the system exits saying killed. trying run: manage.py cities --import=country --force worked, guessing matter of running out of memory. to bypass, tried refer package local copy of cities' data file. still didn't work. any ideas on how can migrate data without having increase memory on server? based on suggestion comments, solved setting temporary swap file. if unfamiliar it, can follow these steps: set swap file touch /var/swap.img chmod 600 /var/swap.img set swap file size cd /var dd if=/dev/zero of=/var/swap.img bs=1024k count=1000 this create 1gb swap file. prepare disk image mkswap /var/swap.img activate swap memory swapon /var/swap.img once done, can turn off swap image: swapoff /var/swap.img more information on virtual memory , swap files can found here: https://www.digitalocean.com/community/tutorials/how-to-configure-virtual-me...
