text rollOver on 3D surface

[frank]

Hi there!!

Anyone have an idea to make text rollover on a 3D surface within Director?

My proposition is to assign simple static text like informations on certain
3D surfaces.

I'm a beginner in 3d lingo programming and i can't find info on the
addOverlay fonction which seems to be the way to do it combine with an
modelUnderlock fonction as far as I know.

There is my testing code after many days of stress, coffee, headaches and
nigthmares :

on enterFrame me
pObj = member("3D_world")
textImage = member("Microphone").image
jTexture = pObj.newtexture("jTexture", #fromImageObject, textImage)
thisSprite = sprite(me.spriteNum)

-- Get the mouse location, adjusted to the sprite,
-- in the old 2D manner.

theLoc = the mouseLoc - point(sprite(thisSprite).left,
sprite(thisSprite).top)

-- Find the model under the mouse closest to the camera

theModel = sprite(thisSprite).camera(1).modelUnderLoc(theLoc)
if theModel = member("3D_world").model("coque_avant") then
pObj.camera(1).addOverlay(jTexture, point(0,0), 0)

end if
end enterFrame me

Other problem:
I made some tests and the resulting text had a very bad resolution without
the capacity to solve this with any Anti-Alias solution.

Plz help me sleep fine!

frank.

I would use previously created images. You have more control over the look
of the images & more control of their size. If you do try this with
images, remember to keep the dimensions to powers of 2 (eg. 128*32). I
have not tried using text as rollover images but have seen some examples.
Any examples that I have seen sound similar to what you are talking about.

One other thing that you might try is to set the texture render format of
the text texture that you create to a higher value:

member(x).texture("XXXXX").renderFormat = #rgba8888
