What are you working on? V7

[QUOTE=jA_cOp;20098994]Nevermind, I found that it is guaranteed. Nice. However, it may have problems if the destructor of a statically allocated global object refers to the singleton, as the order of destruction is of course not guaranteed. I wonder if this is worth it for supporting obscure operating systems that may not fully clean up dynamically allocated memory. I wonder if there is a solution that handles both construction and destruction order...[/QUOTE]

Couldn't you use atexit() ? You'd just have to maybe create a wrapper class that handles the destruction of the singletons in the right order, and also maybe bind to pass a function pointer from that class.

Ah, that's a good idea. Since it would add the cleanup function to atexit before main, it would be one of the last atexit functions to be called, too, meaning any atexit-hooked function set after entering main could also safely use the factory class.

[QUOTE=nullsquared;20098688]Relax smart guy, where's your multi-colored fractal renderer? No need to explain the obvious. My target for the little thing wasn't to make pretty pictures, it was to play with zooming into an arbitrary rectangle, and I did just that.

Good luck getting it to work, I made it ~8 years ago, and the source code is long gone. I know it wont work on 64bit computers, but it does zoom...and it has colors

d = abs(255*sin(time*((x*x)+(y*y)-x-y)))

Not quite the effect I was going for but [highlight]RAVE BREAK![/highlight]

[zeknife]

Are we making cool patterns now
[img]http://i50.tinypic.com/t678n5.png[/img]
(cos(x+cos(time)*time)*time) + (sin(y+sin(time)*time)*time))*10
Wrapped in range 255
I'll look into making a gif

[xxxkiller]

What library are you guys using to make these patterns?
I would'nt even know how to start :(

[Ferret++]

Actually I'd rather have a RTS with good lighting/effects and Physics.

[iPope]

Any graphics libary will do, like SDL or SFML.

I just spent the last 2 hours wondering why my program wouldn't compile and why the compiler thought the constructer had a return type. Spot the big fat obvious error:

Holy crap, That's perfect. And loads of games have been made on previous Unreal engines.

If that's the constructor, I'm assuming it's because you haven't qualified it with the class and :: ?

[Ferret++]

Well I'm planing on an RTS/FPS, not sure yet thought because quite a few or all even, have failed.

That would be (based on the) [URL="http://en.wikipedia.org/wiki/Quake_engine"]Quake engine[/URL], not Unreal.

Edit: this is dumb how? Unreal and goldsrc are two similar engines with completely different backgrounds, only somewhat related in functionality and release dates.

(That and UE3's way different than UE1)

If there was still a Zing rating, this would be one of the few times I would use it; top dollar!

This. How do you guys manage to make these patterns?

[TehDoomCat]

[QUOTE=xxxkiller;20103344]What library are you guys using to make these patterns?

In python:

import pygame, math
from pygame.locals import *
pygame.display.init()

# Configuration
screenRes = (96,96)

# Init shit
xr = range(0,screenRes[0]) # get width
yr = range(0,screenRes[1]) # get height

# The function
def trippyShit():
	pixel = screen
	sin = math.sin
	pxarray = pygame.PixelArray(pixel)
	for x in xr: # go column by column
		for y in yr: # and row by row
			color = abs(255*sin(time*((x*x)+(y*y)-x-y)))
			pxarray[x][y] = color,0,0 # and change the value of each pixel individually

if __name__=='__main__':
	screen = pygame.display.set_mode(screenRes, 0, 8) # the last number is the colour depth, I have it set to 8bpp to speed shit up
	time = 0
	trippyShit()

	while 1:
		time += 0.001
		trippyShit()
		pygame.event.poll() # stop pygame window from going unresponsive
		pygame.display.update()

It ain't difficult to make these patterns on most graphics frameworks, you can do it on a per-pixel basis. Doing it in Python using pygame is easy as hell, but it's nowhere near as fast as using SFML on C.

tan(x*y)

Doesn't get any simpler than that.

[img]http://i45.tinypic.com/2r7r5vn.jpg[/img]
tan(x) * tan(y)

[img]http://i50.tinypic.com/33c29zt.jpg[/img]
tan(x*x) * tan(y*y)

I'll stop now lol.

[zeknife]

I used pygame as well

The noise is just gif compression

[TehDoomCat]

No-one else's algorithms work for me >:C

I always get ZeroDivisionError or ValueError or the unhelpful 'sequence size mismatch' error, even when I tried tan(x*y).

How to wrap the range between 0 and 255 properly? I just divided 255 by the number the calculation gives inside of an abs() function, but obviously that gives weird numbers with e.g. tan(x*y), since I'm getting numbers like 1788.88940062.

number % 255

Oh, and start at pixel 0 on the x and y axis to prevent /0

I have a hunch my 255 wrapping isn't working like it should, but it does produce patterns
In python

def wrap_255(value):
    ret = math.fabs(value)
    while ret > 255:
        ret -= 255
    return ret

Edit: Now that I think about it it should have been pretty obvious that I can just use modulo
Edit: My pattern looks a lot better now
Also I forgot to mention my function also multiplies by Pi before sending to the trig functions

You can use my program for non animated patterns: [url]http://dl.dropbox.com/u/1106779/DisplayFormula.jar[/url]
If you want to code it yourself anything that can draw pixels should work.

Yeah I just got it ranging to 255 just doing this:

try: color = abs(255/int(color))
except ZeroDivisionError: color = 0

It also looks like complete shit. I, too, can assign an ugly ass color to a range of iterations and pretend I'm the pro of mandelbrots. Except instead of doing that, I simply followed my own task, which was to zoom into an arbitrary rectangle, not into a point with a predefined zoom factor.

[noctune9]

Alright guys, reality check.
It seems reasonable to limit my pathfinder to 3000*3000 in order to cut my memory usage by half, right?

Way to blow everything out of proportion, the guy simply posted a mandelbrot he'd made [b]8 years ago[/b] and your criticizing it. He never said he was pro of mandelbrots either. Jesus christ man.

You merely asked him for colors. He provided, and now you change the rules to something that can be completely subjective. You also put words in his mouth.

I'm planning on making a base game, the planet is about to be consmed by it's sun and players(It will be co-op online) have a nearly top down view, there's going to be classes. A class for gathering resources then a class for making the items and attackers, and the teams will be on a race to build a rocket, there will be destructible environment and buildings and the others teams rocket will twist and bend if they lose while the winners zoom off into space.

Good?
