## Limitations
|
|
|
|
LiquidFun uses several approximations to simulate rigid body physics
|
|
efficiently. This brings some limitations.
|
|
|
|
Here are the current limitations:
|
|
|
|
1. Stacking heavy bodies on top of much lighter bodies is not stable.
|
|
Stability degrades as the mass ratio passes 10:1.
|
|
|
|
2. Chains of bodies connected by joints may stretch if a lighter body is
|
|
supporting a heavier body. For example, a wrecking ball connect to a chain of
|
|
light weight bodies may not be stable. Stability degrades as the mass ratio
|
|
passes 10:1.
|
|
|
|
3. There is typically around 0.5cm of slop in shape versus shape collision.
|
|
|
|
4. Continuous collision does not handle joints. So you may see joint
|
|
stretching on fast moving objects.
|
|
|
|
5. LiquidFun uses the symplectic Euler integration scheme. It does not
|
|
reproduce parabolic motion of projectiles and has only first-order accuracy.
|
|
However it is fast and has good stability.
|
|
|
|
6. LiquidFun uses an iterative solver to provide real-time performance. You
|
|
will not get precisely rigid collisions or pixel perfect accuracy. Increasing
|
|
the iterations will improve accuracy.
