(space = fullscreen = more fun)

My engine shouldn’t and doesn’t compete with Papervision3D or Sandy3D, nor it has a very user-friendly API, no stunning effects or animation support, but I learned a lot while building it, understanding 3D to 2D rendering, optimizing the code for a few ms of extra speed (AS3 rocks!) or challenge problems with 3D rotations like gimbal lock and their solutions: quaternions. It’s just another 3D flash engine, at least I can say: I made it! ;)

It’s undocumented, there’s still a lot of work to do and it doesn’t have a cool name , but if you want to play around with it or just take a look how I set up this and that, feel free to download the sources (yes, the 3D ribbon example is included). And I’m always interested in what you think about it, so drop a comment or mail.

A shape-based collision detection for bitmaps by Grant Skinner, since the third parameter in hitTestPoint(x:Number, y:Number, shapeFlag:Boolean) only works for vectorimages and I’m using bitmaps as graphics. A Proximity Manager. This small class comes really handy and the principle is so simple. The proximity manager splits the stage into grids and stores for every sprite in which grid they are. So you don’t need to test every sprite against all other sprites, instead you just say: “Give me all neighbours of that sprite”, which saves a lot of loops.

So I had the tools for a nice collision detection, for the collision reaction I converted a simple snooker algorithm to AS3: Snooker Balls. Watch the result:

Move your mouse over me!

more later ;)

// pseudo code
for each(bombs) {
    for each(shots) {
        if(bomb.hitTestObject(shot)) {
            // shot hit bomb...
        }
    }
}

you go:

// pseudo code
for each(bombs) {
    var objects:Array = shotClip.getObjectsUnderPoint(bomb.x, bomb.y);
    if(objects.length) {
          // shot hit bomb...
    }
}

This only works, if you have a seperate clip for the shots. Enough of the talk: Launch!

Just a small test with my 3D Engine, the idea obviously is “slightly” adapted from the latest Flash Player 10 (Astro) presentation at MAX Chicago, but you don’t need the Flash Player 10 for this ;) Launch!

(I’m still working on the engine API, when I’m satisfied with it, I will release the sources)

Just another test with additive Colors. Klick mouse to cycle through the different coloring modes: Launch!

Now my engine supports additive colormixing. It’s slowing the framerate down a bit, at least it looks cool ;) Press space to toggle between additive and normal rendering: Launch!

My Engine is evolving slowly. Features so far:

• Depth sorting
• Backface culling
• Frustum culling
• Camera movement
• Texture mapping
• ASE Model Importer & Texture Loader
• 2D Sprites
• Dynamic flat lighting

I prepared a little Spacescene Demo. A Mouseclick changes the camerafollow between the two ships. The Mousewheel zooms in or out of the scene. Launch!

My first try with the new AS3 sound classes (SoundMixer.computeSpectrum). This test measures the average sound energy, triggers an event if the energy changes and emits a particle. The particles are 2D particles generated with my 3d Engine: Launch!

I’ve been working on my little 3D Engine in the last weeks. Thanks to Andre Michelle’s great Examples I could manage to get the texture mapping to work and integrated a ASE Parser to load meshes from 3d programs. You can draw onto the texture and see the result in the 3d View: Launch!
