Public Attributes
xiiVec3	m_vAcceleration = xiiVec3(0, 0, -10)
	External acceleration, typically gravity or a combination of gravity and wind. Applied to all rope nodes equally.

xiiDynamicArray< Node, xiiAlignedAllocatorWrapper >	m_Nodes
	All the nodes in the rope.

float	m_fDampingFactor = 0.995f
	A factor to dampen velocities to make the rope stop swinging. Should be between 0.97 (strong damping) and 1.0 (no damping).

float	m_fSegmentLength = 0.1f
	How long each rope segment (between two nodes) should be.

bool	m_bFirstNodeIsFixed = true

bool	m_bLastNodeIsFixed = true

Detailed Description

A simple simulator for swinging and hanging ropes.

Can be used both for interactive rope simulation, as well as to just pre-compute the shape of hanging wires, cables, etc. Uses Verlet Integration to update the rope positions from velocities, and the "Jakobsen method" to enforce rope distance constraints.
