I'm starting to build a real-time raytracer for iOS. I'm new to this raytracing thing, all I've done so far is write a rudimentary one in ObjC. It seems to me that a C-based raytracer is going to be faster than one written in ObjC, but the ObjC one will be far simpler, as object hierarchies come in very handy. Speed is very important,...

I'm new to node.js and I want to ask a simple question about how it works. I have used FMs in the past for client to client communication and real time applications. For example, for creating a collaborative application where you need to see what other users are doing. I want to explore that using NodeJS. I have couple of questions: ...
I'm not sure if the term real-time is being misused here, but the idea is that many players on a server have a city producing n resources per second. There might be a thousand such cities. What's the best way to reward all of the player cities? Is the best way a loop like such placed in an infinite loop running whenever the game is "liv...
Is there a very fast compression library for Java? The standard gzip library is slower than I would like. I'm looking for something similar to http://www.oberhumer.com/opensource/lzo/ that's native Java code that provides fast compression and decompression. Thanks! A few other fast compression libraries for future reference: QuickLZ...
In 3D Max Studios, I recalled there is a function (I couldn't recall the name of the function, sorry) to cut a 3D model into two. For instance, you create a sphere, then you cut it in the middle, leaving 2 half spheres. Now, how about a human body? Imagine a samurai cutting up an enemy at the stomach, now that enemy's model will become 2...

I'm working on a existing embedded system (memory is limited, Flash is limited, ...) with an RT OS. All data structures have a fixed size and are allocated at "compile time" and are therefore suited for RT. There is no dynamic memory allocation. The programming language is C++, but there is no STL available. I like to replace some of the...

Hi! I'm trying to write a simple music-sequencer in Javascript. Sounds will be played by SoundManager2 I quickly realised that setTimeout and setInterval are useless for this kind of timing. Their accuracy is simply not good enough. So what I am trying instead is this: Create a queue of sound-events (a 2d array [ note, time ] ) P...
