I've moved this thread to support...anyway: The loader loads polygonal objects only (this is stated somewhere...if not in the javadocs, it may be in the "manual"). That is why straight lines don't show for example. There is simply no matching primitive in jPCT to show them. I don't know about the bevel as i don't know how this works in 3DS Max and what the exporter does with it.
You may want to try to export the model into another format (good old ASC for example, which most likely doesn't support bevel so that it has to be converted to a polygonal representation), reimport it into Max and save it as a 3DS again. Maybe that helps.

BTW: If you are still using the version from Feb. 2004, you should really upgrade. It may not fix the 3DS problem, but it fixes a lot of other stuff...

A similar question: http://192.18.37.44/forums/index.php?topic=10761.0

It was just an example. tempObject3D.setName(nombresMapas ); is better?

Quote from: "Melssj5"
Any idea about how to solve my problem?

tempObject3D.setName("Seleccionador.3DS");   :?:

If you want to do it that way, you have to set the name yourself by using setName(<String>) for the objects in question, i.e. after loading your object, call obj.setName("Seleccionador"); before adding it to the world. But you have to make sure that the name is unique for the world the object belongs too. jPCT doesn't check this.
In Paradroidz, i'm using a subclass of World called Level that holds references to XXXManagers, which are in fact object pools. I.e. an EnemyManager manages all the enemies, an ExplosionManager manages all the explosion...that way, it's always possible to access your objects without retrieving them back from the world. But that's totally up to you, it's just one way of doing it that i wanted to share...it doesn't have to be the best one.

Have a look at the Java Media Framework (jmf). But as far as i've heard, it's quite complicated to use and doesn't work too well. But it's the only possibility that i know of. I've never used it myself.

Quote from: "Melssj5"A suggestion is to do a method that only checks for a collision, it may be useful.

It is there. checkCollisionEllipsoid does exactly that. Again, the fps example should help to clarify this.

Mouse is provided by LWJGL. It is "automagically" associated with the OpenGL frame. You simply create the OpenGL frame, then the Mouse and it should work fine.

Sorry for confusing you with the methods' naming.  In earlier versions, naming was different (something like moveCameraCollision IIRC, which was bogus too). But i agree that the naming is not that good. I just couldn't come up with anything better at that time and now...now i'll leave it this way... :wink:

Have you found a solution? This mirroring seems to be a *strange* feature. I've downloaded the 3ds you are using in your applets from your site and loaded it into DeepExploration (a mighty viewer/converter for all kinds of 3d and 2d files) and while it manages to mirror the parts in question, it "inverts" them, so that the back faces are visible while the front faces are not. So it's also wrong...just different...

To detect if OpenGL is possible, you may get the video modes by calling
FrameBuffer.getVideoModes(IRenderer.RENDERER_OPENGL);
If it returns a none empty array, OpenGL is supported. But that doesn't mean that your SIS651 correctly supports it. SIS is known for crappy drivers and the SIS651 is a joke of a graphics chipset. I also think some people reported problems with SIS and LWJGL but i'm not sure...

Here it is. It may contain some Paradroidz specific stuff, but it should help to get you started.

I agree. I'll add it.

I wrote the importer based on a free, reverse engineered documentation from the net. I don't own 3ds, so i can't really verify this. It seems like 3ds doesn't really copy the geometry but stores the former (unmirrored one) with an additional mirror plane or matrix or whatever...i have no clue. Does it help to export the object into another format and reimport it as 3ds in 3ds?

Don't use checkCameraCollision()...it's ancient stuff that doesn't work well in all cases. I strongly suggest to use checkCameraCollisionEllipsoid instead. Have a look at the fps example to see how to.
