Does it make any difference to bitwise OR 4278190080u and -16777216 (for alpha values) if the result will nevertheless be an unsigned int (I apologize in advance for the C#)?

I've made three dozen attempts. I have had success on a plane with multiple polygons, but I'd like to make it work on a large plane with only two triangles. My best (unsuccesful) attempt:

     public void mouseClicked(MouseEvent e) {
        moveByMouse(e.getX(), e.getY());
     }
     private void moveByMouse(int mouseX, int mouseY) {//WALKBYMOUSE; CALLED ONCE TO SETUP THE WALK DIRECTION
SimpleVector ray = Interact2D.reproject2D3DWS(camera, buffer, mouseX, mouseY);
if (ray != null) {
     SimpleVector norm = ray.normalize();

     float f = theWorld.calcMinDistance(camera.getPosition(), norm, 1000);
     if (1==1/*f != Object3D.COLLISION_NONE*/) {
SimpleVector offset = new SimpleVector(norm);
norm.scalarMul(f);
norm = norm.calcSub(offset);
origin = hero.getRoot().getTransformedCenter();
SimpleVector destination = new SimpleVector(norm);
destination.x += camera.getPosition().x;
destination.z += camera.getPosition().z;
destination.y = origin.y; // Make y the same as for the hero to avoid moving up/down.
hero.getRoot().setRotationMatrix(destination.calcSub(origin).getRotationMatrix());
this.destination = new SimpleVector(destination);
     }
}
go = true;
     }


Can I forcefully update it in order to have an item keep up with my character's hand?

...of keyframes? You should put that in the docs.

For now, I'm going to assume that it is. ; )

I'm about to post a little project for anyone unable to export either Ogre or MD2-animated versions of their models but are able to export OBJ or 3ds. I found a little maxscript that automates the exporting of the frames, and I'm writing the jpct end of it. Problem is I keep getting a size difference of 1 between frame 1 and all the rest ("ERROR: The sizes of the Animation's Meshes (26938) and the object's Mesh (26937) don't match!").

I was working a while ago on this fire particle system. I don't remember the rendering getting clipped like this.

this.setSize(buffer.getOutputWidth(), buffer.getOutputHeight());
this.add(canvas, BorderLayout.CENTER);
this.setVisible(true);
...
     buffer.clear(Color.blue);
     flameManager.update(deltaTime);
     smokeManager.update(deltaTime);
     skyBox.render(theWorld, buffer);
     if (!doShadows()) {
theWorld.renderScene(buffer);
theWorld.draw(buffer);
     }
     buffer.update();
     buffer.displayGLOnly();
     canvas.repaint();

The docs for Object3D state:

public Object3D(float[] coordinates,
                float[] normals,
                float[] uvs,
                int[] indices,
                int textureId)
uvs - the texture coordinates [u1,v1,u2,v2,...]

When in fact it seems to read ws too (thus being u1, v1, w1, u2, v2, w2...).
