Support / using camera.lookAt
« on: October 31, 2005, 11:08:55 pm »
I can't verify this. How exactly are you moving the camera, i.e. moveCamera(int mode, float speed) or moveCamera(SimpleVector direction, float speed)?

Support / Unsatisfied Link Error when swiching rendering modes.
« on: October 31, 2005, 11:07:41 pm »
You have to include the native libs too. Either put them in the current directory (should work...) or use the -Djava.library.path=<your dir>-switch to tell the VM where to look for the native libs.

News / Version 1.08 has been released!
« on: October 31, 2005, 08:55:38 pm »
Ok, i've hopefully found the bug and fixed it. Corrected version should run on your machine. The problem was that i was initializing vertex arrays for non-present texture stages on lower end hardware.

I believe JPCT is 1.1 compatible?For the software renderer path, yes. But OpenGL support requires at least 1.4.

Ok, so only the "normal" GLRenderer seems to have a problem on your machine. I'll check it out on monday. I have a GF4MX somewhere...will try to track the problem down with that. Thanx for testing.

Strange...looks like i'm doing something in the renderer that isn't allowed in that state. Problem is, that this should be the case on every hardware/driver but i can't verify it. It's a damn case of "works for me".
Can you please (if time permits it):
1. Make sure that you have the latest version (i.e. download it again)
2. Try to run the example, press '1' to disable rgb scaling, switch to OpenGL and see if that works
3. Compile the example above and see if that works
Many thanx.

However, I'm wondering if there is a way to make the light one-directional? I can't find any documentation on that, so I guess not. In that case, is the simplest solution to position the lightsource inside a hollow cylinder object? Or would the light shine through that cylinder?No, directional lighting is not possible with standard vertex lighting, which is what jPCT is using. There's no way to let other objects block the light either. jPCT is following OpenGL's specs when it comes to lighting.
For a spotlight, it may be possible to fake it by using a transparent object als light cone, but i'm not sure how good that will look...maybe not too good... :wink:

The forum currently has some problems with sending notification mails. The mail header is somehow corrupted and you may see (depending on your client) an encoded text instead of the correct mail.
I'll let you know, when it's fixed...

Support / How to improve the textures!
« on: October 29, 2005, 10:17:14 am »
What do you mean by "awfull"? The software renderer can't do mip mapping let alone trilinear filtering, so you may see some aliasing artifacts. Maybe you don't like the effect the faked bilinear filter creates (disable it with Config.texelFilter). Usualy, software benefits from low contrast textures, because that will reduce the aliasing.

Java (NOT Lwjgl itself) is having problems with forcing AntiAliasing for Direct3D in the drivers on some (most?) machines. On ATI cards, this results in crashes or black screens. On NVidia cards, it results in very jerky behaviour. Please check if you are forcing AA in the driver settings.

The nullpointer is in your code, as the stacktrace indicates. Judging from the two code snippets, i would say that either you are doing the loading in the gameLoop()-method (unlikely...) or that there are two "demons". One global and one local in the method that loads the animation and the global one isn't initialized, just the local one!?
Index always goes from 0 to 1. 0 is first key frame, 1 the last. The sequence numbers start at 1 (with 0 being the whole animation) and match to the sequences printed out while loading, i.e. in your example:
pigstand=1
pigwalk=2
...
Have a look at the Animation-class for more information on animations. There's also a method to get the sequence count from an Animation.
You may get the Animation of an Object3D by calling Object3D.getAnimationSequence(); (silly name, i should deprecate it and replace it with getAnimation();...anyway...)
