Hi
How would you guys do to make a transluscent Cube in Away3d ?
I’ve tried some simple things, but stuff like myCube.alpha=.2 or myCube.blendMode=“whatever” doesn’t seem to work ?
Also, another noob question : how do you delete a particular face of a Cube (to make, say, a box) ?
Thanks!

Try material.alpha = 0.2;

Rather then delete a face, you could construct your box using five planes.
That way you’ve also got control over the material on each side separately if necessary.

Thanks a lot. I guess this can be applied to a single face, not only to the material ?

Well, if you use the 5 planes idea, yes!

Thanks.
Well, I speak of different projects though I made only one post.
In the first one, I need to apply transparency to Cubes, to make them look like glass, sort of, so I’d like to know if the alpha can be different from one face to another.
In the second one, I need something like a box, so your idea seems to be very relevant.

If I were you I would make a copy of the Cube.as, and call it MyCube.as (remembering to rename the class and constructor), then you can edit that to function just how you like, and you will get an insight into how to build your own primitives in Away3D.

Thanks again, I’ll try to do so, or to extend Cube.as, unless it is final.
(cannot check it right now, being at home…)

trying to play with alpha on material, I got this error :
1119: Access of possibly undefined property alpha through a reference with static type away3d.materials:Material.
Is there something I am missing ?

ColorMaterial(0x98d061,{alpha:.2}) does the job !
But, then, I still don’t know how to access this property dynamically, as I get the same error as above when trying to modify the alpha of a face…

i have been mapping a transparent png file to the face of a cube to get this effect.
eg:
var transparentSide:BitmapFileMaterial = new BitmapFileMaterial(“images/tranparentSide.png”);
myCube.cubeMaterials.left = transparentSide;

this works dynamically, but it’s probably not the best solution processor-wise - very simple code-wise
