Your problem could be due to integer division. In this line

glu.gluPerspective(45, width / height, 1, 50000);

if width = 199 and height = 200, then width / height = 0 by integer division. You should do something like this:

glu.gluPerspective(45, ((double)width) / ((double)height), 1, 50000);

Technically only one double cast is needed, because Java will auto-promote the other one
