In #44, we talked about various choices of integrator for the NCMCEngine, including GHMC and VV. I think it would be convenient to have an API for deciding which integrator to use. I'm starting this t…

Hello,
I'm trying to make a Body jump after an impact with the same rebound no matter what. The documentation specified that:
`If you need to modify a body's velocity directly, you should either app…

Hi there. I plan to toy around with a top-down game. Did not see a Z axis gravity option nor a way to simulate it.
How can i do it?
Thanks.

While talking about enemies, we mentioned hit-boxes. I thought it could do with its own issue.
I believe my thinking on hit-boxes stems from this article: http://devmag.org.za/2011/01/18/11-tips-for-…

The current implementation of the simulation engine uses an Euler step between intervals which may result in the loss/gain of total energy. Overall energy must be conserved and therefore the Euler so…

I'm hoping to converge some density (water, organic solvents) calculations to 4 or 5 decimal places. However, I'm finding that my density estimates have a timestep dependence of 1E-3 g / mL (TIP3P) o…

So I've been implementing and debugging various hamiltonian monte carlo methods. For most systems, my methods seem to be working, as measured by comparing the expected value of the potential energy w…

Set up a framework for symplectic integration:
1. StatePair, which contains Hamiltonian coordinates; two NumState objects.
2. Something similar to Derivative, except it has two methods, one for positi…
