Novodex, Ode, tokamak, bullet, Newton ......

I am dead in these five physical engines.
I can't say I understand it very well.
A simple understanding

What I want to say most is that docization is really important ....
Among the five, novodex is the best documented.
Very detailed, including the idea of engine implementation. Every member of each class has a clear explanation of what it is.
The other four are getting worse.
The worst keys are tokamak and bullet.
Where Tokamak is the difference
I can't even use official forums, and I still have dating posts ....
Ode is also poor,
All three are automatically generated using doxygen,
In addition to one sentence for each class, I have not explained much about it.
You can only use the function literally,
Sometimes it's terrible. For example, the coordinates of these three engines are not all the same.
Ode seems a little strange. When I mix Newton and ODE
It is found that the Z of ODE is up .....

Newton was so careless that it was not detailed.
However, this document only provides help for all functions, and only slightly includes
I 'd like to know the organizational structure of the class,
But there is no information to provide. Is Newton really just a function library?

Performance,
Novodex does not need to be said. It is very strong in all aspects.
Ode is excellent in quick-step, but it is the worst in collision and is very poor. If there are more than one object, it will be severely distorted.
Tokamak: Rigid Body simulation and collision are both good. The engine is well encapsulated and simple to use, but not flexible enough.
NEWTON: collision is good. I have never heard of the rigid body.
Bullet: the speed is fast, and the collision is very good. However, the usage seems to be much more complicated than the previous ones, just initialization work.
It is much more than others, but it is also true that the usage is quite flexible and can be used with others, such as ode,
The author also provides a demo used with ode's quick-step.

ConclusionCommunityBesides the tokamak community, the other four are very enthusiastic,
Ode has mail-list and can subscribe
The engine authors in the Newton and bullet forums answer users' questions every day.
I am very enthusiastic. I will also ask you about the suggestions for improvement, which is very good.
However, if the dockerization is better, many problems can be avoided.
