[Overv]

I decided to write a simple raytracer today, simply because I've never done one before.

[img]http://i.imgur.com/OG8RA.gif[/img]

Code to create the scene:

[cpp]scene::camera cam = scene::camera( math::vec3( 3, 3, 3 ), math::vec3( -3, -3, -4 ), math::vec3( -0.7, -0.7, 1 ), 1, 1, 90 );
scene::world world = scene::world();
world.addPrimitive( new scene::box( math::vec3( -3, -3, -0.1f ), math::vec3( 3, 3, 0 ) ) );
world.addPrimitive( new scene::sphere( math::vec3( -1, 0, 0.5f ), 0.5f ) );
world.addPrimitive( new scene::sphere( math::vec3( cos(time)*1.0f+1, sin(time)*1.0f, 0.5f ), 0.5f ) );
world.addPrimitive( new scene::sphere( math::vec3( 1, 0, 0.5f ), 0.5f ) );
world.addLight( scene::light( math::vec3( cos(time)*3.0f, sin(time)*3.0f, 2 ), 1, 1, 1 ) );[/cpp]

HUD :D

[img]http://i3software.org/s/SS-2011-08-04_16.56.57.png[/img]

A HUD Component acts as two separate layers: Background and Overlay.
Background is used for the background of the HUD. (Duh)
Overlay is used for adding objects over the background. (Again, Duh)
Since the HUD of my game consists of meters, I decided to use a block based approach again.

enum HUDColor {
    Blank,
    Border,
    Background,
    Brown,
    Red
}

class HUDItem
{
    protected HUDColor[][] Background;
    protected HUDColor[][] Overlay;
}

Dodging questions, awesome. Just for fun, nope. Have you ever worked with C++ in a remotely large project?

[QUOTE=Jookia;31538014]Dodging questions, awesome. Just for fun, nope. Have you ever worked with C++ in a remotely large project?[/QUOTE]

Yes and it usually looks like someone threw up on the screen.

[Jookia]

Then stop writing messy code. Simple. It's not a language barrier, it's that people suck at writing clean code.

[Ltp0wer]

Holy fuck. I don't know if I'm doing things I shouldn't be, but C++0x kicks ass.
Initializer lists for the standard STL containers was probably the greatest idea ever.

[cpp]#include <iostream>
#include <vector>

using namespace std;

int main()
{
vector<vector<int>> vec = {{1,2,3,4,5}, //PURE
{1,2,3,4,5}}; //SEX

for (vector<vector<int>>::iterator i = vec.begin(); i < vec.end(); ++i)
{
for (vector<int>::iterator j = i->begin(); j < i->end(); ++j)
{
cout << *j;
}
cout << endl;
}
return 0;
}[/cpp]

I got inspired by everyone making roguelike dungeon generators, so I wanted to start work on one.

[Jookia]

Well, there goes my premise.

[icantread49]

[QUOTE=Jookia;31538014]Dodging questions, awesome. Just for fun, nope. Have you ever worked with C++ in a remotely large project?[/QUOTE]

yes, multiple in fact (both my own and foreign code bases)

the irony is that i used to feel the same way as you before i really started using C# for large projects

you can't judge something without giving it a really good effort

Use C++0x's ranged-based for loops.

That's weird, Fraps said 20 to 25 FPS for me. Same exact specs.

I tried feeding the Batman Equation and it was too big for Wolfram Alpha.

So about that nullular grapher?

[QUOTE=Jookia;31538605]Use C++0x's ranged-based for loops.[/QUOTE]
I would love to, but the latest MinGW only has GCC 4.4, and I need GCC 4.6 for range-based for loops.

I'm open to compiler suggestions though.

Blue shifting here takes into account the speeds of the viewer and the moving object. This is a picture of the planet when the viewer is moving towards the object at the speed of light

Edit:
The shadows that ill definitely need to fix make this an alright looking oceanic planet when the observer and object are moving towards each other at the speed of light

Surprisingly enough, the whole doppler effect only adds 0.0015ish seconds to the frametime (currently ~0.058), which is quite fast

Aaaand he's back.

Note the large projects he's talking about are just a couple of his own projects, basically a grapher and probably whatever that simple cartoony game was we saw earlier.

As a Linux user I don't have a problem with Mono's implementation, it runs fine. I do not like the insane amount of software patents around C# or Mono.

Some of their wording is extreme, but nothing they say is untrue.
