ActionScript 3.0 :: Z-sort Triangles For A 3D Engine?
Sep 18, 2010
I'm building a small 3D engine for a game I'm working on. I've got my basics sorted: textured triangles with backface culling. However depth sorting is proving to be a difficult problem.I'm calculating the face Z by averaging out the 3 points that make up the triangular face. The longer faces sometimes overlap the smaller faces since they have a larger Z value and therefore rise up in the depth sorted display list.Is there a way I can use the area of the polygon to influence the depth sorting in any way? Or are there algorithms to accurately detect which triangle is above which triangle?

I need help with page "Thumbs" (as first frame), page "List" (as second frame) and Image gallery (as third and base). So, every frame have one own XML file...When you choose some thumb or list line, you must came to this image in the gallery. Easy, sure.. but i don't know what Function exactly i need to use.It's one flash move, hence it doesn't work with getURL or loadMovie...Some exemple with 3 separate pages here: yuri.fr

I have an array that is structured like so.
[Code]....
Normally, I'd just like to sort the array alphabetically using the name field, which is easy enough using the following code. However, I'd like to create a radio button called 'loadedRadioButton' and when it's click on, I'd like to sort the array on the loaded value first(any items with loaded=true should be at the top, sorted alphabetically), then afterwards, any other items with loaded=false, sorted alphabetically should follow afterwards, how can I do it?

Here is a website that needs a sort function to sort the video by Last name. [URL] I would like to have a link that popped up videos sorted by last name. Please take a look at the following site for an example. [URL] When you click on seconds in the menu below, it opens a pop-up window that sort the videos in a certain way. If you are willing to,I will give you the source file of what it currently has on [URL]

At first I thought making tringles out of Polys was an easy concept. Considering I start with a quad of ABCD then I could convert this to two triangles of ABC and ADC, which is easy. However an alternate answer is BCD and BAD. The real differnce between the two outputs is exacerbrated when I now calculate the Normals for the two new faces. Also in some cases the edges break against the UV texture map in an undesirable way. Obviously in choosing the output faces I should be choosing the method as well that doesnt produce highly acute angles above all else. Unfortuantely I also have a number of pentagons and hexagons to render as well.

This is a test program to measure the time it takes Flash to draw a triangle 10,000 times. The app (code below) calls runTimeTest() every N seconds which draws the triangle 10,000 times. Now for the "interesting" part: each call takes increasingly more processor until after about the 6th or 7th call it goes to "infinity" (see screen shot of TaskManager) Weird bug or explainable??

I am trying to achieve something similar to the flash movie in the below link. [URL]. As we drag the points of the triangle, the coordinates labels, ( A(1,2)) are properly aligned and arrange themselves so that they never collide with each other and never falls inside the triangle.

I am trying to calculate the top most intersection of an arbitrary number of planes, with no joy! I am using actionscript, but just need find an algorithm that i can implement.
Problem:
consider 3 vertical axis.The user enters 3 points for each triangle/plane such that the points of the triangle lie on one of the axis.The user can enter an arbitrary number of triangles I need to find the topmost layer of these triangles and display it on the screen as well as the coordinates of interection.
Here is a picture to clarify what I mean with 2 triangles:
However, when we allow for more than 2 triangles, I get awkward lines of intersection.

When I get a collection back from the service tier, I create an ArrayCollection and apply a sort. When I add an item to the collection later on, the sort is still in place? It seems to be the case. I thought I was only sorting it once, not applying a sort that will stick??Here is the method for adding an item:
private function onAddNewClick():void
{
var fileTemplate:FileTemplateDetailDTO = new FileTemplateDetailDTO();

My new project consists in setting a CD containing a structured data sheet (CVS, XML or Excel) and a serach engine. The idea is to allow the user (even not connected) to make searches live on the CD. There will also be a up-to-date version of the data on internet so if the user is connected, the application will prioritary load the online data.I was thinking at using ACTIONSCRIPT and XML.My questions are:1- Is ActionScript + XML a good choice?2- Is it possible to think at PHP + XML (so how to embed PHP on a CD without a sever?)

I am in need for some 2D physics seen from "above and straight down". Basicly I can sum it up with a "throwing balls into walls" kinda physics.
There seem to be quite a few physic engines for as3 out there, but I wonder if anyone have anyone special to recommend regarding my particular need as well as performance of the engines.

I recently benchmarked the four most popular 3D engines (Papervision3D, Away3D, Sandy, and Alternativa3D). The latest versions of each. Default settings, no mip mapping or any advanced features turned on.My main reason for doing this was to see how my 3D engine compared, performance wise. But I thought I would post the benchmarks, as I'm sure some of you might find them interesting, or useful, if you use Flash 3D engines.First I'll explain the benchmark and why I did this particular test. It's 1000 texture mapped planes, 100 by 100 pixels, each comprising of 2 polygons. So that's 2000 polygons and 4000 vertices being rendered per frame.Now my reason for doing textured mapping is because the vast majority of people are going to use texture mapping in their 3D work, as opposed to wireframe or vector filled polygons, so obviously the texture mapping performance is important.And I decided to do 1000 small planes, rather than just one huge 2000 polygon plane because this test has a significantly larger amount of vertices than 1 big plane, thus being more of a test for the 3D transformations.Also being that there are 1000 planes, it tests how quickly the engines traverse the list of models, do the transformations, and add them to the renderer each frame. Again, this is more of a task than having just 1 model.Now as for the results, funnily enough, they are pretty much ranked in terms of popularity Papervision being the clear winner, then Away3D, then Sandy, then Alternativa.I get 19fps for Papervision, about 11fps for Away3D, 7.5fps for Sandy, and a shocking 2.5fps for Alternativa.It's given me a new found respect for Papervision. It has very respectable performance, much faster than the rest in terms of raw poly pushing power. I previously thought PV was overrated, and it's success mainly due to great marketing etc, but no. From the demos etc, I thought away3D would be faster, but actually PV is almost twice as fast.It's impressive that they've created a very easy to use, versatile and user friendly engine, with pretty good performance to boot. I think underrated PV before, because I'd seen fairly simple things like a 3D menu, or some 3D images run at like 10 frames a second and use 75% of the CPU. In hindsight, this was obviously just some horrible programming, by people who didn't know what they were doing.
I thought I would stick up for Alternativa though. It might lose badly in terms of raw polygon pushing, but it's a very advanced engine, and goes about things in a different way. The reason it can handle those big scenes in the demos on their site is because of some fairly advanced clipping and dynamic triangulation, minimising the amount of polys being rendered at any one time. Particularly the dynamic triangulation. Objects that are further away have their polygons reduced dramatically, then more polygons are added when viewing up close, particularly at an angle.Kind of surprised about Sandy. Having a skim through the classes, it seems pretty well written and fairly lightweight and streamlined. Papervision seems a bit bloated in comparison. But PV's code is clearly far more efficient.I'd also like to say this doesn't mean you shouldn't use Away3D, Sandy, or Alternativa. Obviously I explained A3D above, and I know Away 3D has a lot of features that people like, and things generally look quite good in Away3D.

How the heck do you Kern in Flash CS5 while using the new TLF text engine?
There's no letter-spacing control and the keyboard shortcut doesn't work.
I'm not interested in auto-kerning. I'm looking to tighten up large text like headlines and logos and stuff.I'm starting to suspect it can't do it.

my virtual keyboard is up and running. I am on the last leg of this project and what I need is, I am assuming complicated. Senario... the user types the department, suite number, or name of a particular person, the typing ends up in an input text field, with an instance name of "dirsearch". then the user clicks the button "Enter" and in theory the input text field, searches a file, and retrieves information which will be displayed above the keyboard. Most likey a bio sheet of what ever the user typed. But I need it to be flexable on the spelling of what the user typed into the input text field.

I want to use a simple tween engine (mc_tween.as) with a custom Class of mine.
Basically, so when one Rolls over the MC instance, it tweens to the side.
I just cannot get my custom class to communicate with the tween class though! therefore it just doesn't work.
Is there a line of code to let the actionscript codes to access each other?
