[QUOTE=Icedshot;30875170]Just realised that mandelbrot set generation is an embarrassingly parallel problem

Should easily be able to get it to run much faster![/QUOTE]

You can use parallel_for from ITBB or Concurrency Runtime(if you use Visual Studio and don't mind being locked to one platform) to make most algorithms run in parallel.

Alternatively you can use OpenMP, or even push it one step further and use OpenCL/CUDA to compute it on the GPU.

I think I'm actually gonna work on it now. Last opened in July '08..there's gotta be something I can do to it..

Unless you're using some build-system, in which case look at its documentation.

[QUOTE=Overv;30876528]How do you guys do first person camera systems? Up until this point I've always just had a pitch and yaw variable and calculated a view normal with some 2D trig. I feel there's no need to get into quaternions and the like if I don't need roll.[/QUOTE]

being the high-level abuser that i am :v:
[cpp]
Node yawNode = new Node();
Node pitchNode = new Node();
yawNode.Children.Add(pitchNode);

// later
Matrix4 viewMatrix = pitchNode.DerivedMatrix;
viewMatrix.Invert();
renderer.ViewMatrix = viewMatrix;

wasd to move around, r to zoom in, f to zoom out, C to decrease the number of iterations and V to increase the number of iterations. B saves a nice, 2048x1536 image (bmp), with AA. Which sadly this version has lost (in realtime), apparently due to how sfml likes rendering multiple "smoothed" images to a renderwindow

Unfortunately due to not massively responsive controls, the only way to tell if its saving the current image is to hold b for about a second, then see if its locked up while its generating everything :v:

You have options to stop it too, and remove items from the list and clear it too. You can customize the message box too.[/QUOTE]

the real question is, does it stealthily hide in your notification icons so that you're not tempted just to exit it :v:

since OpenGL likes matrices, I have 3 3d vectors, the up vector, the right vector, and the forward vector. Since I don't need roll, I only have a pitch and heading variable. I can break the 3d trig down to 2d trig by assuming that the right vector will always be parallel to the X/Z plane.

I ended up using boost::thread. The times ive looked at OpenCL have convinced me that its much, much easier just to live with it being on the cpu

Trust me. In most cases, using a thread-pool library is much faster than using plain old threads. For instance, any time you spend blocking (waiting for a computation, etc) is given to a different task, threads don't kernel-block.

GPU computing isn't that hard, but it's kind of long and tedious to set-up and implement.

It's all up to you. I wouldn't use it for side-projects to be honest; unless the speed gain outweighs the effort.

You get an open dialog that lets you add .exe's to a list, and if you open any of the programs (or if they're already open) it closes it and tells you "NO! BAD NOW! GET BACK TO WORK YOU SLACKER!"

You have options to stop it too, and remove items from the list and clear it too. You can customize the message box too.[/QUOTE]

The multithreaded version creates 4 threads, it should run two on each core and be faster than just ploughing through it single threaded-ly. Ill try creating a two threaded version

I'm working on a First Person Camera for my game. But I'm not sure if I should make the equipped item (gun, melee weapon, etc) sway back and fourth as the player moves, or if I should implement head bobbing instead. Thoughts?

Yeah, if I end up adding head bobbing it's going to be really subtle. I read too many comments about people feeling dizzy or sick because of exaggerated head bobbing.

[QUOTE=NorthernGate;30883307]Yeah, if I end up adding head bobbing it's going to be really subtle. I read too many comments about people feeling dizzy or sick because of exaggerated head bobbing.[/QUOTE]There are a lot of elements I'd like to see in games that people never get right. Head/weapon bobbing is one of them. Another is reloading/crouching.

[editline]555[/editline]

By reloading and crouching, by the way, I mean that reload animations are always dumb. It's as if the person is running around the game with every single clip in their other hand. By crouching I mean that it's odd to be able to crouch in less than a second over and over.

[Downsider]

[QUOTE=Quark:;30884279]By crouching I mean that it's odd to be able to crouch in less than a second over and over.[/QUOTE]

How are you crouching? I can crouch in less than a second too. I think it would be better if you can't move while crouched, because I can barely do that. I have to half stand to get any momentum at all.
