Hi Helge,

I'm trying to point a camera at an object with this:

camera.lookAt(obj.getTransformedCenter());

It works, but afterwards my camera movement develops a fault. If I move the camera forward, the camera moves along the 'old' path (the path I would expect it to take if I hadn't performed the lookAt() ).

Any idea what might be happening?

Not sure if this is a bug, but I have a template object3D that I use to spawn new 'enemies', like this:

              enemy = enemyTemplate.cloneObject();
             
              enemy.translate(0, 0, 0);
              enemy.setTranslationMatrix(new Matrix());
              enemy.setLighting(Object3D.LIGHTING_ALL_ENABLED);
                           
              theWorld.addObject(enemy);

The problem is, my enemies don't seem to react to light sources at all.

The enemy model was created in MAX and uses default diffuse colours (I don't manually texture them after importing with the load3ds method). Have I missed something obvious?

Thanks..

A question for Helge..

I'm trying to soften (anti-alias) the edges of my on-screen objects. I've  used frameBuffer.getPixels and blurred the image array. This produces a good result but it's a bit slow. I also tried SAMPLINGMODE_OGSS_FAST, but the result wasn't quite what I was after.

Any suggestions/ideas gratefully received.

I'm building an applet and thought you might like some pix:

If, like me, you're experimenting with the excellent 'fps' demo bundled with the API, and you're using 3dsMAX for modelling, you might find this useful.

I was trying to modify the main .3ds map file using an ancient copy of MAX (v3.1 I think), but I discovered that if I imported the file then immediately re-exported it again, all the textures vanished and I was left with a load of blank white models in the demo.

It turned out that when 3dsMAX exports .3ds files, the embedded .jpg filenames get converted to uppercase, so the demo no longer recognises them.

To get around this, change the following line in JPCTDemo.java as follows:

From this:

texMan.addTexture(name , new Texture("textures"+File.separator+name));

to this:

texMan.addTexture(name.toUpperCase() , new Texture("textures"+File.separator+name));

Recompile it, and you can now mod the .3ds map using 3dsMAX and see the result immediately in the demo.
