Smoothing

Hello everybody,

With away3d I import 3d models into flash builder 4.5 as follows:

package
{
      import models.example;

      public class model extends Sprite
      {
           public var model_example:example = new example;

           public function model()
           {
                view.scene.addChild(model_example);
           }
      }
}

In the file 'models.example.as' a jpg is used as texture for the model:

[Embed(source="picture.jpg")]
private var Obj_000001_Bitmap_Bitmap:Class;

Picture.jpg is a picture of some text and it's not displayed very well.

I found something about smoothing on this site: http://www.allforthecode.co.uk/aftc/forum/user/modules/forum/article.php?index=4&subindex=4&aid=121

The text on my model is just as the text on the right cube in that article. I would like to have it as on the left cube but it seems that it does not work in my case.

Could anybody help me further?

Correct answer _spoboyle

well i get the smoothing effect you need to set smooth = true on your materials and as far as i can see you are not doing that

set inside applyMaterialToMesh

meshes.material.smooth = true

however I am no Away3D expert and I can't say for certain this will fix you issue with out your fullproject you can't attached a zip file here you'd have to email it me

Thanks! It's working correct!

I never thought it's that easy.

I have an other ac3 problem which I still can't solve. Maybe it's also easy for you.

You have two discs, an frontdisc and an backdics. These discs are parallel. The backdisc contains text and the frontdisc has a window so you can see the text on the backdisc through the window.

When you click on the frontdisc with the mouse, the backdisc is turning 360 degrees.

You also can turn the complete model (frontdisc and backdisc) with your mouse. If you do that, you see that you have a depth sorting problem. You can see the text on the backdisc through the frontdisc (not the window).

Is it possible to make the text on the backdisc invisible and make it only visible when it's behind the window? I think I can solve the depth problem in this way.

I think it has to do with masking but I have no idea how to do that.

Maybe you don't have any idea what I'm talking about. I can mail you this complete project and you will see directly what I mean.

By the way, maybe it's better to start a new discussion.

This one isn't going to be so easy for me to fix.

I have seen other people have similar issues though and their problem was a matter of scale.

Do you still have a problem is you increase the distance between the dics?

try increasing the size of the model that might fix the problem

Thanks for reply.

Yes, I still have the problem if I increase the scale of the model.

By the way, I started a new discussion about this problem: http://forums.adobe.com/thread/933832
