我公司正准备提出一个中风和脑损伤康复的工具，我们需要知道什么是免费的，开源的，而且证据充分的游戏引擎都在那里。

My company is getting ready to propose a stroke and brain-injury rehabilitation tool and we need to know what free, open-source, and well-documented game engine are out there.

我们将构建一个3D环境。 我们需要有很好的控制字符精细动作（比如，即使手指运动）。 我们需要一个良好的物理引擎，包括冲突检测和反向运动学如果可能的话。 如果已经有一些钩子在code提供触觉反馈，但是这是没有必要这将是非常有益的。 在图形并不需要是惊人的。 在它必须的相对的简单拼凑概念验证。 We will be constructing a 3D environment. We will need to have good control over characters fine motions (for instance even finger motions). We need a good physics engine including collision detection and inverse kinematics if possible. It would be very useful if there are already some hooks in the code for providing haptic feedback, but that's not necessary. Graphics do not need to be phenomenal. It must be relatively easy to throw together a proof of concept.

我pdisposed朝Jake2 $ P $因为Java的死很容易在编程，但我需要更多的选择从你的乡亲谁拥有的经验来考虑。

I'm predisposed toward Jake2 because Java's dead easy to program in, but I need more options to consider from you folks who have experience.

我会考虑寻找 ioquake3 这是一个雷神之锤3的开源端口同时，我想指出，这是美国mod出资开发的开源仿真引擎的出色Delta3D的。

I would consider looking at ioquake3 which is an opensource port of Quake 3. Also, I would like to point out the excellent Delta3d which is a DoD funded and developed opensource simulation engine.

巴黎圣母院评估几个引擎在纸上协作的调查虚拟环境技术。我认为，这将是最好的起点是当应用到虚拟环境中，您将能够访问在发动机上现有的知识很多。

Notre Dame evaluates several engines in the paper A Survey of Collaborative Virtual Environment Technologies. I would think that this would be best starting point as you will be able to access alot of existing knowledge on engines when applied to virtual environments.
