Re: Automated flying object

But how do I "negate gravity" and "apply forces whichever directions I wish? By literally modifying current object's position? Is it the right way? I guess by doing that I might override the bullet engine positions and rotating procedure algorithm. Is there a way to "apply the force" so, bullet can ...

Automated flying object

Hey guys... Back to action... I am studying forces because I need to create a automated flying object like a quadricopter for example. He needs to receive an external force and react correctly to then. So let's begin with a easy context. With a given cube with a 1Kg of weight how can I implement a f...

Re: Industrial Simulation & Modelisation

How do think to load the models and the model's action into Bullet?



PS: models = machinery

Re: Industrial Simulation & Modelisation

So what? Sometimes cinema industry requires eye candy instead of accuracy. And the accuracy required at a industry work method is far more demanding than filmaking. If isn't 100% accurate and predicted the bussiness model can be invalidated, someone could get hurt or even killed. Anyway, I really th...

Link Objects [jBullet]

Hi. How can I link objects?

Imagine a cube sitting on origin and another one (linked to the first one) sitting on 10,0,0. How can I rotate or even move the first one and the other guy follow its motion. But related to.

If I rotate the first one around the Y axis, the other guy should orbit around.

Re: Java port of Bullet

The model loading issue was solved.


But I got another doubt. How is the best way to implement a altimeter?

Given a position x,y,z a ray must be cast down on the Y axis until hit something. The distance between this object is your altitude. Right?

So, how can I do that?

thanks

Re: Java port of Bullet

Sure debio. But there is only the MovingConcaveDemo(bunny thing) that reads a static array of vertices and faces indexes. So I've been trying to write my own Model Loader based on that structure(vertices and indexes). The routing reads the data from a file generated from a maxscript exporter I wrote...

Re: Java port of Bullet

I've made my way and it worked.

Now, another question. It's possible to load a custom model and use its mesh to run some simulations?

Thank you.
