Xiao Xiao Style 3D

[MX789]

heres another site it has been posted by old newbie before.

i finally found the authors email. I emailed him. I wonder if he'll reply

[MX789]

Awesome if he does tell me waht he said!

[csplaya]

his email is xiaoxiao@xiaoxiaomovie.com

[MX789]

when he responds tell me becasue im also curious

[csplaya]

its been a long time, and still no reply from the author. I think the email i sent it to has been abandoned long ago

[jerez_z]

I'm not sure if he is still doing it. I remeber it must have been a year ago when he did the last one, and it was supposed to be continued, but nothing yet........

[csplaya]

ok
so far people have told me to use these methods for 3d:
freehand
actionscript
flash frame by frame

i dont know which is the best one

[jerez_z]

I prefer using actionscript because it allows the perspective to be perfect (plus I can't draw worth crap :P)... but thats just me

[csplaya]

lol ok.
What is the code for it and how would it work?

[jerez_z]

the tutorials at Bit-101 are very good. Once you go through those you'll realize that the concept is actually quite simple.

[csplaya]

o yah that site. Someone recomended it to me earlier in this topic.

[csplaya]

i just tried the tutorial. ITS SO CONFUSING!!! It may be because im not trying hard enough. It got really confusing with all those formulas and stuff. Can you help me?

[jerez_z]

well the main concept is pretty simple. Using the z value and a focal length (Bit uses 150, all this really does is adjust the speed at which things shrink and grow) we can determine a scale amount (an integer between 0 and 1 derived from the formula scale = focal_length/(z+focal_length)). Then we multiply the x and y values by the scale amount to provide us with a 2D representation of 3D.

code:

---

x = 100

y = 100

z = 100

fl = 150

scale = fl/(fl+z) //scale now equals 0.4

x_toscreen = x*scale //places the x on the screen at 25

y_toscreen = y*scale //places the y on the screen at 25

alpha = 200*scale //gives the illusion of fog // returns 50 percent alpha

---

not that the above code will move the x and y position toward the top left corner as the z gets greater. I use a holder clip with it's 0,0 at the center of the stage so everythinbg receeds toward the center.

I know this is really old, but I have to bring closier to this.

Swift 3d wouldn't have been an option as mentioned due to xiao xiao's early release date, and action scripted 3d would be out of the question because of how slow it would render on even decent computers.

What is an easy possiblity is making the scene in something like 3d studio max, export it from that, import it into flash and trace over the edges. I used to do the same method in the days prior to swift.
