http://nodename.com/blog Mon, 14 Jul 2008 02:09:09 +0000 http://backend.userland.com/rss092 en Adding color to the previous example, we obtain tinted Perlin Clouds; allowing the color values to overflow past 1 gives us Perlin Plasma. A shift in coordinates reveals that the Frocessing implementation of Perlin noise is symmetric about all three axes (not necessarily implying that it's incorrect if you ... http://nodename.com/blog/2008/07/13/perlin-color/ Here are two instances of the same demo, modeled after the one Seb Lee-Delisle showed last fall, built with two different Flash implementations of 3D Perlin noise. The one on the right uses Ron Valstar's Perlin class (as does Seb's demo), which appears to be a faithful port of ... http://nodename.com/blog/2008/07/11/perlin-clouds-and-frocessing-with-an-f/ In ActionScript 3, classes (and functions as well) are objects that can be manipulated like any other object. The language provides us with some constructs to facilitate this, and they are an important part of the programmer's toolkit. We need to be able to traverse the connections among the Class, ... http://nodename.com/blog/2008/06/15/upon-reflection/ With the recent advances in Flash 3D and panoramas, and the fact that Flash 10, now out in beta, has intrinsic support for arbitrary warping of triangles, we can look forward to a future of increased performance and the complete disappearance of those wavy lines in panos. All of ... http://nodename.com/blog/2008/06/05/behind-the-beyond-or-beyond-the-behind/ Can anybody show me a use case for the following? (Flex language manual, Object.constructor) Advanced users may choose to use the function keyword instead of the class keyword to define a Function object that can be used as a template for creating objects. Such a function is called a constructor function because ... http://nodename.com/blog/2008/01/13/advanced-users-may-choose/ The past few days have seen the release of version 1.1 of Thomas Pfeiffer's AS2 (and soon to be AS3) 3D library Sandy -- check out the great kitty demo! -- and of Andre Michelle's AS3 CubicVR immersive panorama application (requires Flash 9 of course).  (For a bit of technical background, check out Andre's post ... http://nodename.com/blog/2006/08/01/two-exciting-developments-in-flash-3d/ In a post entitled Testing the Flash Gradient Fill Method, and Some Personal Thoughts, Kinglong's Blog (zh) presents a neat little swf reminiscent of the test swf in Psyark's DisplacementMapFilter Tutorial. This one demonstrates the effects of various parameters of the beginGradientFill() method in Flash. (But not ... http://nodename.com/blog/2006/04/06/real-live-docs-gradient-fills-transitions-tweens-and-flex-css-explored/ In my Flash 8 bit-twiddling adventures I've found it useful to be able to check the colors of individual pixels in a running swf. If you need that too, I offer you the PixelTip class, a variant of my ToolTip class that simply displays the coordinates and value of ... http://nodename.com/blog/2006/03/27/pixeltip/ I've posted a cubic panorama example in the Sandy forum. If you haven't seen the announcement yet, this awesome ActionScript 2.0 3D package has just released version 0.2. It's early days yet for Sandy but already things are very impressive. Check out the features, the source, ... http://nodename.com/blog/2006/01/27/the-sandy-as2-3d-api-and-a-flash-cubic-panorama-tutorial/ This just in, from Warp9 Community: altro link ultra-ultra-geek (solo testo e codice): http://nodename.com/blog/category/actionscript/ che tratta di alcune questioni estremamente specifiche come il surface mapping in flash. http://nodename.com/blog/2006/01/26/ultra-ultra-geek/
