Rigid body (shape) in bullet/ammo.js from a mesh in three.js

问题 I am using bullet/ammo.js with three.js. I have a 3d mesh and I want to use the exact shape for collision detection with a soft body. Is there a way I can create a 3d rigid body (in bullet) from a mesh (in three.js)? Here is an example: http://kidzinski.com/miamisura/lazy3d/ (please wait a second for the 3d model to download). I have a cloth falling on a 3d body and I need to simulate collision of this cloth with the body. I am new to these frameworks sorry if I fundamentally misunderstood

BulletPhysics (ammo.js) - How would you applying force directed to a point?

问题 I want the Force converge to a point of the scene. So the Force will not be the same on each point of the scene (like Y vector) but change direction in the space. It is like gravity converge to the center of the Planet or Star. How would you do this with Ammo.js ? Best regards PS1 : Firstly, I want exactly to rewrite this example with Ammo.js : http://lo-th.github.io/Oimo.js/#planet PS2 : My final intention is to rewrite this example of gravity in 3D with Three.js and Ammo.js : https://bruno

问题 I'm creating a WebGL game and it's really much faster after some time using it. Every time I run it for the first time it's slow and stutters. Would running some CPU intensive code for few seconds first prepare browser to use it's full power? I'm already running ammo.js in a worker which gives an enormous boost, but first few minutes of playing are still much slower. Could this be my laptop strategy to manage power? 回答1: I can think of 4 things: The browsers use a technique called JIT (Just

It looks like you can do some work to turn an arbitrary Three.js mesh into a Bullet concave
