Blockparty 2010 Invtro and the Opensource demo engine evoTinyEngine

Blockparty is an annual demo party held in the US, and 2010’s is about to hit in a few months time. As with all good demo parties there is usually an invitation demo to announce it, and to whet the appetite somewhat. This year EvoFlash created this little beauty, and of course it’s AS3 to the core:

I’ve not been to a demo party since 1999, but boy does this make me wish I could be there. Nice one guys, nice one.

There are some lovely effects as you’d expect. Evoflash have been at this for years now, and obviously have a highly streamlined demo pipeline going on. With impressive pre and post render effects; gorgeous blooms, radial blurs, reflections and shadowing. And what’s more – they have released it as open source, free for demo coding plebs like me to use!

Called evoTinyEngine it’s a small framework that offers you three core elements: Assets, the main Engine and Modifiers. The Modifiers can be stacked up on-top of each other. The Engine handles the construction and destruction of all the Modifiers for you, and there are some really nice things ready to use. Everything is based on 16th note beats, which allows for tight syncing with the audio in your demo.

I haven’t dug through the code much yet but I’d be willing to bet there are some insane routines in there, that would be well worth studying for game development as well as demos.

(Now let’s see if this blog post kicks off a 20+ comment flame war about “is it really a demo?” yadda yadda … 😉

    This looks really good! Downloading as I write this! Really like the appearance/hide effect that they’ve put on the texts.

    I had a good play with it last night – it’s basically a really solid rendering engine and all the building blocks you need to construct a nicely time-synced demo, but without any of the effects that make a demo worth watching. You get a few in the sample project (a could of distorts, chroma blurs, etc) but nothing all that interesting. Which means you’re left with a kick-ass framework and nothing to do with it, without a lot of coding :) which is a damn shame! But maybe they will release new Modifiers in the future. I sure hope so.

    yeah just skipped through the code a moment ago and found out the same, not much of implementations so far.

    Guys… The point is that _you_ make effects and eventually the demo. That should be the fun part, you know :)

    naah. nobody of us has the time to make effects! we need prefabs, man ,prefabs! 😉

    The problem Simo is that I’ve absolutely no idea how you make some of the effects seen in your demos. I honestly wouldn’t have a clue where to start. But I could put together a decent bitmap render framework :) I was just praying it would have some of those effects included, but I appreciate why they are not.

Make yourself heard
