gravity

Overview

Python OpenCL "gravitational" "fluid" simulation
Not real gravitational potential ( too much spreading speeds with G/(D+eps) )
Pressure potential : -Density*PRESSURE
Friction affect particles velocity sharing same discrete location

Dependency

OS
	QT4 OpenGL OpenCL
PYTHON
	pyfft pyopencl pyopengl

Python variables

N -> number of particles
D -> spatial discretization size

CLkernel defines

GRAVITY
PRESSURE
FRICTION
