2. Papervision 3D Programing Tutorial - 3D Spectrum Analyser    hubpages.com

The computeSpectrum function takes a ByteArray as an argument, populating it with 512 float values: 256 for the left side and 256 for the right side. What is confusing about this though is that those 512 float values actually exist as 2048 byte values (4 bytes to 1 float). This means that to get the 2nd float value for the left hand side (assuming we have passed in a variabled called spectrum which is a ByteArray), you need to first need to call spectrum.position = 4, followed by a call to spectrum.readFloat(). Why 4? Because the first float takes up the first 4 bytes, those being at positions 0 - 3 inclusive. The second float starts at position 4, and the 3rd at position 8 etc. This is important because almost all of the sample code out there that reads the float values from the ByteArray do so with a series of calls to spectrum.readFloat() (which advances the position by 4 internally with every call). This sample creates a number of seperate objects that reference their own position in the spectrum ByteArray without any regard for the order that other objects have accessed it.

In order to achieve the DOF effect we create a call called DOFMeshObject. This class extends the MeshObject class, which in turns holds a Papervision DisplayObject3D that is rendered to the scene (a simple box in this case). The actual DOF effect code is contained in the enterFrame function, which applies a BlurFilter with increasing "fuzziness" to the DisplayObject3D depending on how far the object is away from the focal point of the camera.

6. Papervision 3D Programming Tutorial - Modify Textures At Runtime    brighthub.com

The implementation of this is actually quite simple. The majority of the code used to create this effect is the same as in the previous article, so if I suggest you take a look at that first. We make only 3 significant changes to enable modifying the texture of the Papervision 3D model at run time. The first is in the ResourceManager.

9. Papervision 3D Programming Tutorial - Animated Textures    brighthub.com

Currently Flex does not have the ability to embed a FLV file (which is a native Flash video format). While an FLV video can be played, it has to be loaded from a web server or local file through a NetStream class. Fortunately though there are a number of tools that can convert video files directly to SWF files, which Flex can embed. For this demo I used the ImTOO FLV Converter (a demo version is available on the ImToo website).

10. Papervision 3D Programming Tutorial - BitmapViewport | Bukisa.com    bukisa.com

In previous demos I have shown how you can add some of the standard Flash effects to individual Papervision 3D objects, allowing you to blur, modify colors and add a glow to a 3D object. In addition to adding effects to objects, you can also add effects to the entire viewport thanks to the BitmapViewport3D class. The BitmapViewport3D has a bitmapData Property, which you can then apply a filter to with the applyFilter function. You simply supply the same standard Flash effects classes, like Blur, to the applyFilter function after rendering the scene.

11. Papervision programming tutorial - 3D Text | Bukisa.com    bukisa.com

A good logo can be eye catching, and the difference between your product attracting a customer, or being overlooked. And an animated logo certainly does catch the eye. This tutorial shows you how to create a moving 3D text logo with Papervision.

12. Papervision 3D Programming Tutorial - Environment Mapping | Bukisa.com    bukisa.com

Yesterday I showed you a Papervision application that displayed 3D text, which could then be rotated and interacted with as you would any other Papervision object. I mentioned that some of the inspiration for that app came from the Windows “3D Text� screensaver. There was one big difference though: the screensaver displays shiny, reflective letters, whereas my app only had a solid colour.

13. Papervision Programming Tutorial - SkyBox | Bukisa.com    bukisa.com

One of the easiest ways to generate the look of this outside world is with a sky box. As the name suggests it is essentially a box that contains the player (or more specifically the camera). If you move the box so its position is always centred on the camera, and make it large enough to encompass the 3D world that the player is looking at, the player gets the effect of a distant vista that surrounds their local 3D world.

14. Papervision Programming Tutorial - Animations | Bukisa.com    bukisa.com

When I was looking for documentation about displaying animations in papervision the general consensus was to use the DAE class and load up an animated Collada mesh. That seemed simple enough, until I wanted to find a decent Collada animation to use as a demonstration. Having artistic skills that resemble the end result of 3 year old who stuck a crayon up his nose and then sneezed on a piece of paper I was reliant on grabbing a freely available animation off the web. Not an easy task with a Collada file.

15. Papervision 3D Programming Tutorial - Transparency | Bukisa.com    bukisa.com

Transparency can be achieved in Papervision quite easily by changing a default parameter in the MovieMaterial constructor. The parameter called transparent (which is the second parameter in the MovieMaterial constructor) is set to false by default. This is because transparent materials are more computationally expensive than opaque ones. However if you do need to make a material transparent all you need to do is set this parameter to true.

16. Papervision 3D Programming Tutorial - Texture Smoothing | Bukisa.com    bukisa.com

Texture smoothing is something that PC gamers have come to expect ever since the very first Voodoo 3D cards came out on the market way back when. Even today the most basic of integrated graphics chipsets will display smoothed textures. Unfortunately before Flash Player 10 there was no hardware rendering available to Flash programs, and as a result 3D engines lie Papervision typically default back to rendering textures in the same old school blocky format that now days is associated with software renderers.

17. Papervision 3D Programming Tutorial - Fog | Bukisa.com    bukisa.com

There was an old PC game that I used to love called Magic Carpet. It was one of the first 3D games that featured an outdoor world. Its biggest drawback was the limited distance that you could see: the game made heavy use of fog to limit how much of the world was actually drawn, and therefore maintain the frame rate. It’s a simple and effective trick.

18. Papervision 3D Programming Tutorial - Enhanced Fog | Bukisa.com    bukisa.com

Previously I showed you how to use the FogFilter to implement a fog effect in Papervision. While it does the job, personally I think it’s a bit rough. Objects seem to pop out of the fog in jarring intervals, and for some reason there is a big performance drop when you set the segments over a certain amount.

19. Papervision 3D Programming Tutorial - Terrain | Bukisa.com    bukisa.com

There are dozens of ways to create 3D terrain, and there are many examples of this being already being done in Flash. There aren't many examples in Papervision though, nor does Papervision support a standard terrain mesh.

20. Papervision 3D Programming Tutorial - Simple LOD | Bukisa.com    bukisa.com

In 3D applications Level of Detail, or LOD for short, refers to a process that alters the polygon density of a mesh, generally reducing the polygon count the further a mesh is away from the camera. The idea is that only those objects close to the camera need to be rendered with full detail, and that reducing the polygon count for smaller, more distant objects increases performance without sacrificing too much in the way of visual appeal.

21. Papervision 3D Programming Tutorial - Mesh Splitting | Bukisa.com    bukisa.com

New to Papervision 2.0 is the ability to slice a mesh into two parts. If you have every watched the movie Cube then you'll have an idea what I am talking about :). Seriously though, this does have some neat uses. In fact the first time I became aware of this functionality was because of a Papervision demo that allowed you to smash up a pane of glass and then have it shatter and fall to the ground. Unfortunately I can't find the demo again (I'll link to it here if I ever do find it), but it did pique my interest.

22. Papervision 3D Programming Tutorial - Quadtree Renderer | Bukisa.com    bukisa.com

A common problem with a software 3D rendering is deciding the order in which triangles are drawn. Why is this important? It's important because those triangles furthest from the camera need to be drawn first, so those closer to the camera can draw over the top of them.

23. Papervision 3D Programming Tutorial - Billboards | Bukisa.com    bukisa.com

Billboard is a term that refers to a 2D plane in a 3D world whose face always points at the camera. They feature heavily in particle systems because they are computationally inexpensive, but when used in numbers can create a very detailed effect.

24. Papervision 3D programming tutorials - Clipping & Culling | Bukisa.com    bukisa.com

In this post I will be looking at two concepts in Papervision: culling and clipping. They are easy to confuse, but both have very important roles.

25. Papervision 3D Programming Tutorial - Trails | Bukisa.com    bukisa.com

There is a blog entry over at http://blog.zupko.info/?p=264 which sows you how to add trails to Papervision objects. If you ever played the game Wipeout you'll know what these trails look like. Needless to say they are pretty cool, and with the code supplied in the blog entry very easy to add to your own project.

26. Papervision 3D Programming Tutorial - Blend Modes | Bukisa.com    bukisa.com

I've shown you how you can use the standard Flash effect classes, like BlurFilter, to add effects to Papervision models. All you need to do is set useOwnContainer to true and you are free to start adding effects to the effect property.

27. Papervision 3D Flash Gallery Tutorial | Flashmoto    flashmoto.com

In this tutorial we’ll try to build a Flash Gallery using Papervison 3D. First of all I’d like to mention that the main aim of this article is passing through all stages of flash application development. At the same time we would like to discuss all contradictory questions one may face while working with Papervision 3D. More likely this tutorial will consist of several parts. Together with Papervision 3D library we’ll use Tweener for a better smooth animation and BulkLoader for a better image preloading.
