我想使滚动立方体像骰子反应加速度计。因此,加速计给出了棱镜移动的参数。我认为,小的物理应该在这里使用。我的问题是什么配方,技术,我应该用它来实现这一点没有任何物理引擎。
I want to make rolling cube like dice that reacts on accelerometer. So accelerometer gives parameters for cube moving. I think that small physic should be used here. My question is what formulas, techniques should I use to accomplish this without any physics engine.
推荐答案您可能需要使用OpenGL了点。有一个良好的物理教程 OGL这里
You will need probably to use OpenGL for that. There a good physics tutorial for OGL here
具体的骰子,看看这个诺基亚演示。这是写在CPP(这里 源)
Specifically for dice, take a look at this nokia demo. It's written in cpp (source here)
在物理学方面,你可以看看本网站。
On the physics side, you can take a look at this site.
无论如何,我不认为你需要的真正的物理学的应用程序,但只是一个近似值:
Anyhow, I do not think you need real physics for the app, but just an approximation:
- 我会开始得到的速度取决于加速度计(加或减,比方说,20%)和随机的角速度了解的霸气。
- 然后,找到 的轨迹为每接触边框时。
- 弹跳他们以一个或另一个方向取决于在特定时刻的旋转。
- 更改角速度的符号,如果骰子反弹。
- 减少约50%,每一个反弹的速度,直到阈值。
- 在门限以下,留在他们的地板和停止运动。
- I would start getting a velocity that depends on the accelerometer (plus or minus, let's say, 20%) and random angular speeds for the dice.
- Then, find the trajectory for each and when touching a border.
- Bounce them to one direction or another depending on the rotation at that particular moment.
- Change the sign of the angular speed if the dice bounce back.
- Reduce the speed about 50% each bounce, until a threshold.
- Below that threshold, leave them in the floor and stop movement.
