There is a project on SqueakSource by Chao-Kuo Lin that contains OpenGL part of Croquet *without* positional arguments.
To get OpenGL running in 3.9:
1) install FFI and Balloon3D from SqueakMap Package Loader
2) open Monticello HTTP repository:
MCHttpRepository location: 'http://www.squeaksource.com/OpenGL' user: '' password: ''
3) select OpenGL-ckl.4.mcz and load it
4) apply attached change-set
5) make sure, that Squeak.ini contains
B3DXUsesOpenGL = 1
6) and play :)
OpenGLMorph new openInWorld.
