More With the JiglibFlash Terrain

Playing around a bit more with the animated JiglibFlash terrain idea from my last post, I wanted to see how it would work in conjunction with a webcam. So, needless to say, you’ll need a webcam to check out the results below. The trouble, I’ve found, is that when you create the JTerrain instance, you specify the number of horizontal and vertical segments to create (similar to instantiating a simple Plane object in Papervision3D). Unfortunately, my experience is that if you go over about 12 or 13 segments, the application begins to chew through memory like skittles. So, stuck with using only 12 horizontal/vertical segments, the results are fairly abstract (with 50 or more, you can see a clear definition of your face but, again, you can’t run it very long before it freezes up and eventually crashes). Still, even in an abstract way, the finished product is pretty cool and kind of spooky. With a little luck, the JiglibFlash guys will run across these posts and implement this animation feature in a more optimized way rather than my half assed hack job. We’ll see. Still working on a jiglib ragdoll idea…

Rockin and Rollin with the JiglibFlash Terrain

Finally got the chance to play around with the new JiglibFlash height map terrain, today, and have to say I am very impressed! The first thing I noticed missing, though, was the ability to update the terrain in order to use animated height maps. I tried deleting then creating a new terrain inside a rendering event handler. This actually worked better than it sounds like it might. At least for a very short time. Going this route, within less than a minute, the frame rate dropped from around 58 to around 15 and the memory usage was well over 400 and climbing steadily to an inevitable crash. I knew an update function was needed for any animation. Before I dig into the nerd stuff, have a look at what I’m talking about. Double click the example below to see an animated JTerrain instance in action (double click on it a second time to stop the animation and save a bit of processor power). And this is just using perlin noise. You could also use sound data (mp3 or microphone), video data, etc. etc (giving myself some ideas and goosebumps just thinking about it). If you’d like to try this out […]
