Since everybody is posting patterns, [url=http://s206.photobucket.com/albums/bb161/itsbth/PHP%20Pattern%20Making/]here[/url] is something I made in PHP about a year ago.

Jumping on the fractal bandwagon, I wrote this few years ago:

It's that buddha-related fractal (I recall it's made by displaying how many iterations it takes for certain iteration to leave the boundaries, not just IF it leaves boundaries)
I decided to see how easy it was to emulate UnrealScript's states in CLOS.

Not that large, actually, although using thunks isn't the obvious choice in a Lisp-2. It's rather like APL where it takes me three days just to get this correct.
I need some maths help. My maths is failing me.
Say I'm drawing a series of lines along the x axis like this
|||
Is there an established formula to draw a perfect curved corner, by using x to determine the height of the line... so it's like..
|i.
The only way I can think of doing it is by using atan2 to work out the angle, then using cos to get the height of that angle. But that seems lousy.
Pythagoras?
y = sqrt(r^2-x^2)
-snip-
What is r?
[QUOTE=garry;20154364]What is r?[/QUOTE]
Radius for the rounded corner.
[QUOTE=turby;20154361]ohlol. go back to year 8 when they were teaching you Pythagoras' theorem bro[/QUOTE]
That's from the equation of the circle, which follows the Pythagorean theorem.
Oh man thanks, I never really understood the Pythagoras stuff in school
-schnipples-
[QUOTE=turby;20154427]Well whatever you do, change his minus to a plus.[/QUOTE]
Why would you do that?
r^2 = x^2 + y^2
That is Pythagoras Theorem, therefore:
y^2 = r^2 - x^2
y = sqrt(r^2 - x^2)
[QUOTE=turby;20154427]Well whatever you do, change his minus to a plus.[/QUOTE]
Uhh.. We're not calculating the hypotenuse.
[QUOTE=noctune9;20154443]Uhh.. We're not calculating the hypotenuse.[/QUOTE]
okidokie, read the the word 'pythagoras' and jumped to a conclusion
Yeah Pythagoras != Pythagorean

I have no idea how you made botch / gwen, I mean, with all that shadow mapping, normal mapping, and then there is gmod...
I call sorcery, we must burn garry at the stake.

Best looking one in entire thread.

I know, it's insane. I can only really understand stuff if I have a use for it. I don't retain maths in my head. I learn it to make a function then that's it, I just use the function from then on.

I have to admit, I also do the same with any math stuff. I spend some time converting it into a function then I just use it as a "magic" function.

It's not brown on my screen.
Same color:

It is only red. There is no other color in this color than red. I don't see how you see it as brown.

It does [b]look[/b] brown. Has to do with the surrounding colours.

Because it is too dark and because of the surrounding colours.
Displaying the colour on its own is useless, surrounding colours play a huge role in how you see colour.

It looks the same to me in the screenshot and on the page

Then again I'm using my laptop with a small resolution
Just wrote a high-performance function to switch the endianness of any object:
[cpp]
#ifndef ENDIANNESS_HPP
#define ENDIANNESS_HPP
#include <algorithm>
template<typename T>
T switch_endianness(T i);
template<typename T, int i>
struct Endianness
{
static void swap(char* array)
{
std::swap(array[(sizeof(T) - i)], array[i-1]);
Endianness<T, i-1>::swap(array);
}
};
template<typename T>
struct Endianness<T, 0>
{
static void swap(char* array){}
};
template<typename T>
T switch_endianness(T i)
{
char* array = reinterpret_cast<char*>(&i);
Endianness<T, sizeof(T)/2>::swap(array);
return i;
}
#endif[/cpp]
I didn't manage to make switch_endianness a templated friend function of Endianness with GCC; it didn't complain about the friend declaration but still complained that Endianness::swap was private. If anyone knows how to properly use friend in this case, please tell me!
Usage:
[cpp]
#include <cassert>
#include "endianness.hpp"
int main()
{
unsigned short i = 0xAAFF;
i = switch_endianness(i);
assert(i == 0xFFAA);
i = switch_endianness(i);
assert(i == 0xAAFF);
return 0;
}
[/cpp]
(thanks to gparent for the idea of using std::swap)
