ActionScript 3.0 :: 3D Rotating Sphere Texture?

Dec 29, 2010

i'm trying to achieve the effect of a rotating sphere given a regular 2D texture. the best thing i've seen is a tutorial on emanueleferonato.com which gives this result: emanueleferonato dot com /downloads/mapping09.swf as you can see, it works pretty well when you're moving left/right OR up/down. it fails to simulate realistic rolling when going in any diagonals (since it's a very simplistic illusion). how to render such a sphere given any point on a mercator projection and then have the sphere rotate in an arbitrary (but fixed) direction? this is a bit advanced math stuff.

btw, if anyone's interested, i figured a better displacement map than what is used in the link i showed

i started my search again and immediately bumped into this: [URL] it's library called BitmapSphere and it does exactly what i need it to! also, could admin edit this and put together the link or something? i find it highly annoying that i need 50 posts before being able to post a link

Mar 7, 2005

just download my project and look at the missile code. I need to find out the equation make it so that the fire that is attached in the mc moves as if it didn't inherit the missile's coordinates(i.e make it so the fire moves like it was outside the missile's mc, and doesn't move with it) I know it has something to do with the circular rotation code found in the tutorials but i just need someone to write out the code.

ActionScript 3.0 :: Overlaying 1 Bitmap Image On Another On A 3d Sphere?

May 24, 2009

The basic concept: I want to at runtime overlay (or paste or whatever) one bitmap image asset onto another. The original image asset is a texture on a 3d sphere.Example:3D Sphere with earth texture applied to it. Put a cloud on the earth texture and have cloud move along the earth.

Caveats:Can't use any composite materials because I take a serious perf hit. Want to try working only with bitmaps to see if it is faster.I've gotten this far but don't know how to fill rectangle with jpeg file and certainly have no idea where to go from here..earthBitmap= new BitmapData( 256, 256, true); fillRect will only do a color ... I need what fills a rect with jpeg image and how to edit a bitmap on the fly.

In application u can rotate mainSphere in both x and y axiss'.

Flash :: Inputting Equation In Textfield And Processing It?

Apr 3, 2012

I would like to know if theirs a way where you can type in a text field something like "5*5".

And then on enter, the document would take the database and be able to return 25.

I am quite confused due to the fact that content that you input into a textfield must be a String and when you use the Number() converter the system gets confused.

Actionscript :: Format Input Text Into Equation Using It?

Aug 8, 2010

I am very new to action script, and using action script 2.0, I am having a problem getting an input textbox to read in mathematical formulas. To enter 5x^2, the key sequence to be used is {5}{x}{2}. i.e., the characters must be formatted as it is being typed.

Ultimately, I want to enter equations like 5x^2-4x-2.

The textbox should not allow non-numerical characters other than x.
