Objects which disappear

[JayJay]

Hello !

I am using jPCT to render stellar systems, but I have a problem : some objects disappear...
Here are 2 screenshots :

The system contains 2 planets, a sun and an asteroid belt :


And with a translation along Y axis (bottom of the screen), some asteroids disappear :


I guess I have to change a parameter, but I haven't found which one...
Any ideas ?

BTW, congrats for the software renderer, very powerful and useful

Are you getting a message that too many polygons have been added to the VisList (or similar...)? Try to change Config.maxPolysVisible to..let's say 10000 and see if that fixes the problem.

You are right, I guess there were too many polygons to render (but I didn't get any message from jPCT...)

Actually, I have a class StellarSystem which extends World, and I changed Config.maxPolysVisible in the constructor of this class. I tried to put the call before building the object, and now it works

Just an advice : add in the Javadoc that Config.maxPolysVisible should be set before building World instance

And thanks for your help !

Strange...you should get that message unless you've turned logging off or are using a slightly older version. Which version of jPCT are you using?
The behaviour is documented. It says in Config: "This value has to be modified before constructing a world."

I was using an old version jPCT (1.06) that I used few months ago for a game, that's why the Javadoc wasn't updated and I didn't get any warning...

Sorry, my fault, I shall pay more attention next time
