Is someone still using odejava with xith3d?

Is someone still using odejava with xith3d?

I can't answer this question and I don't use it.

But I advise you to use JOODE. Amos Wenger is currently working on an abstraction layer for physics engines for xith and will also make JOODE use it. He will finish it in january. So it is the best idea to use JOODE and switch to the abstraction layer when it's ready.

ODEJava is a C++->Java wrapper, which has some known problems to sometimes crash. It is advisable to use JOODE also bacause it is pure java.

Marvin is (unsurprisingly) right. Beware, though : JOODE don't support trimeshes.
But convexes shapes are implemented (never used them)... I thought of porting the OPCODE library but it's too far to tell for now.

Anyway, good luck with your project !

I use odejava in my simulator. And it works fine... well.. until I installed
xith3d-0.9.0-beta2.
The simulator starts with 40fps but then drops to 3 fps really quick.
I have tried to use both RUN_IN_SAME_THREAD and RUN_IN_SEPARATE_THREAD.
When using RUN_IN_SAME_THREAD its slow and if I use RUN_IN_SEPARATE_THREAD
it simply crash due to not have found a joint.

I will not switch to another physics engine until its fast and reliable.

is JOODE as fast as ODEJAVA?

Please update to the current SVN trunk. These things have been fixed there. If you wish I could release the next beta on the weekend. But I would prefer to wait a little longer to release it. So only, if you don't like to handle with SVN. But I highly advise you to install Subclipse and checkout the projects. This way you will always ahve the newest version installed.

Marvin

PS: I didn't try any physics engine so far. Sorry.

[Skuggan]

OK! I wait until you have uploaded the new beta. I have other stuff to do meanwhile.
The users on my forum just have to wait a bit longer with the next beta.

I really appreciate your work and the support you give.
Is there any donation I can give you guys the keep you motivated?

I can't speak for everyone here, but simply using, testing, and giving feedback on xith  provides lots of motivation. Everyone likes to see their code in use.

[Skuggan]

Yes! I find that even better than money to have your code running at big companies or in peoples machine.

But maybe I could build an altar to pray at, or sacrifice a goat.

Yeah. On the other way, if e.g. I (poor little open-source dev) want to begin working on Shaders, I'll have to change my Geforce 4 MX440 SE for, say, a Geforce 7900GS But I'll buy it in PCI-Express, so I'll have to change my motherboard, and thus my processor, and my RAM, and if I want decent performances with not that much money I'll have to overclock which means a good case (with a 25cm fan) and a good power supply + two ventirads (one for processor, one for RAM)... Then I'd have a decent config to start working on scenes like that :

So if you have 750€ to spend, don't hesitate 

More seriously I think to divide money between the devs would be too difficult.

[Skuggan]

Hey! Isn't €750 for a gfx card a bit much?

yeah and you are right. Dividing the money betwen the devs would just cause a riot
and nothing would be done.
But if you sort that out a volunteer donation could be good. Companies like me could contribute since our goal is to make money on the product.
But those that cant afford dont have to pay.

Anyway. I love your work.

Testing, using and contributing is a very valuable donation. Of course not much is worth more than money. But in this case, it would not be the right thing.

But if you have a company, that uses Xith, you could display a Xith-Logo on your website. That would be really great.

Marvin

PS: I will try to release a new beta today.

Read my post again 750€ is for a new case + power supply + 2 ventirads + motherboard + CPU + graphic card + 1GB RAM But don't worry, I'll gain enough money by myself (Well if you have a paid mission for me..  )

Anyway. I love your work.

Thanks

[Skuggan]

Ahh.. for the whole computer. Isn't that a bit cheap?

Maybe I just give you the Terrain class later on. We have to see.

Hehe I was joking about the money, though 750€ is really the price of the upgrade I'll buy soon (I buy separately the parts and assemble it myself).

About the terrain class, Cylab's working on one for Xith3D... so maybe collaboration is possible.

[Skuggan]

I have made my Terrain specific for my purpose and right now it doesn't support giant areas. But its fast and it uses odejava for the collision.
