Re: [Flashcoders] Skewing text

2007-07-20 Thread Jake Prime

Hi

Returning to this now as it seems simple distortion is not
satisfactory and I do need to have real perspective. I have played a
bit with Papervision and it's not too hard to render text with
perspective. However the designs that I am working to require quite
precise placement and orientation of the text. Using the distort class
I could simply specify the 4 points of the plane in 2D space on the
stage and render the text like that, but this is not the way
Papervision works.

My question is, is it possible to render a plane in true perspective
just by specifying the 4 points in 2D on the stage? In Zeh's diagram
(http://hosted.zeh.com.br/misc/perspective.png) he shows that you
can't split the line 50-50 to get the 3D halfway point, is there a way
of working out what the proportion would be? If so I want to ammend
the distortImage class to take this into account.

Yes as Zeh has illustrated the Sandy distortImage class distorts, and does
not create perspective. For my purposes this is fine as the perspective is
not too pronounced (certainly not disappearing off into the horizon).

 Yes, but again - be careful. Skewing/distortion is not perspective. If
 you do that with text you won't get the same result as a star-wars-like
 text, as the glyphs that are farther from the viewer won't be vertically
 scaled as they should.

Re: [Flashcoders] Skewing text

2007-07-20 Thread Jake Prime

OK I have worked out how to divide up the space into triangles to
create perspective:

http://www.rjprime.co.uk/perspective.html

However now I cannot for the life of me get the right matrix to use in
the beginBitmapFill function to correctly map a texture. Can anyone
help me with being able to map a specific triangle from a bitmap to a
specific triangle area on screen. I have calculated the points for
both.

Thanks

Re: [Flashcoders] Skewing text

2007-07-02 Thread Jay Carlson
can you take what David said, only actually skew the text/object with  
the free transform to give the illusion of 3D depth...ie: make the  
top of the text thinner and the bottom wider.  this will give the  
perception of the top of the text going back into space and the  
bottom being out towards the viewer.  I did it in Illustrator...so I  
figure you can do it in Flash.  now, animating it that way might be  
trickier...

Subject: Re: [Flashcoders] Skewing text

 I need to skew some text to give the impression it is going off  
into

 the distance (think opening text on Star Wars, though without
 movement). I know this effect can be done using the triangular  
method

 as used in Papervision. However I'm not creating a 3D scene here, I
 just want the skewing. Can this be easily done with Papervision, or
 can anyone recommend any other resource (AS2 only)?

 I understand the principles behind the technique, I just don't  
want to

 re-invent the wheel by implementing from scratch.

The effect is not just skewing. It *is* 3d, in the meaning that the
perspective is distorted because the middle points are moved away
depending on the angle. So yes, your faster/best bet would be to  
use any

3d class such as Papervision3D. It should be fairly simple as you'll
just need a rotated plane with the content of a movieclip  
projected on it.

Re: [Flashcoders] Skewing text

2007-07-02 Thread Duncan Reid

chiming in a little late on this one...  i need to preface the fact that i
have not tried using these classes YET but this cat:

http://lab.mathieu-badimon.com/

seems to have packaged up some nice stuff here:

http://five3d.mathieu-badimon.com/

along with some documentation and a getting started guide.

again, i haven't tried it yet but on the surface it looks like something you
might be able to toy with...

good luck,
Dunc

Re: [Flashcoders] Skewing text

2007-07-02 Thread Hans Wichman

Hi,
I put together a very simple example for fun, maybe it's of use, nothing
fancy though and pretty unoptimized.
