To place an object3D at scenespace coordinates where the user mouse
hits a face of a given geometry when pressed
You just have to set a MouseEvent3D on your Sphere object.
like this:
mySphere.addOnMouseDown(myMouseDownHandler);
private function myMouseDownHandler(e:MouseEvent3D):void
{
trace("I can place some 3d object at :"+e.sceneX+", "+e.sceneY+",
"+e.sceneZ);
}
its all in the doc :))
search in doc at MouseEvent3D to get more info on the properties
available in this event object.

Hi Fabrice,
Thank you for your response. Much much apreciated.
My apologies if what i ask is pretty simple for more experienced
away3d developers.
I have the example from here:
http://www.flashmagazine.com/articlefiles/away3d/Basic08_sphere.as
or in action
http://www.flashmagazine.com/Tutorials/detail/away3d_basics_5_-_primitives_part_2/
using the sphere that has the panoramic image mapped to it. Started
with that and modifed some of the code.
So essentially i would like to be able to have a button that when it
is active when i click on the sphere it places a point on the spot.
And also then draw lines and maybe embed external objects.
I hope that better illustrates what i mentioned before.
And now for me to research the ideas you suggested before and find
some examples to get me started.:)
Once more thank you.
Cheers
Dan

Hi Dan,
a picture would help, since there are many ways to achieve
interactivity into Away3D.
but here a few leads:
You might want to look at the MovieSprite class in the sprite package.
You can pass your btn, a movieclip, to this class.
you can then addchild it to your scene, with scaling properties set
to true, this 2d information will be placed into your 3d scene.
you can add regular flash mouse events to your btn. This objects
have then an x, y and z properties.
To trace lines, you can use LineSegment.
For your sphere material, if you use a MovieMaterial, the movieclip
you pass to it can hold interactivity as in 2d.
Finally your sphere could be interactive as well if you add a
MouseEvent3D to it.
the mouseEvent3D event returns you a data object with 2d
projections, 3d information such as the face that triggers the
mouseevent3d
uv coordinates etc etc...especially handy if you need to alter the
sphere material from user mouse information.
you can find more examples in our examples section, our doc and of
course searching in this group.
I hope this will help you getting started.
Welcome to Away3d!

Hi all,
I have started with one of the examples on away3d that has a sphere
and places a bitmapMaterial - jpeg file on the sphere.
The camera is placed inside the sphere.
That is all working nicely.
Now what i would like to do is to be able to draw points and lines
onto it. Like maybe have few buttons that will activate the operation.
Like for example when the user activates the point button and they
click on the sphere a point will be placed in there. On the clicked
X,Y.
And vice versa with drawing the lines.
So far i have not been able to implement that.
Any advice or example would be appreciated.
Cheers
Dan
