Tetrahedral interpolation
|
I'm working on a voxel renderer (have a look if you want) and an important part of the algorithm is 3d interpolation. As in, without the interpolation it doesn't work properly. I'm not too worried about the quality, it just has to be there. At t... |

Photon Arena
|
These images (well, most of them) chronicle the last 3 days, which I spent making Photon Arena. This is the start of my month of games. I'm foolishly attempting to see how many games I can make in roughly a month (till my holidays end). It was all in... |

Projectile motion

I'm attempting to find the angle to fire a projectile at such that it lands at a specific point. I have only done (in fact, I havn't even completed) high school level physics and calculus, so please bear with me. Here's what I've done so far:

Critique my catapult
|
First off, I'm not an artist by any stretch of the imagination. I'm a programmer (meaning this is programmer art) and I'm only 17. But I spent a lot of time making this catapult for my 4E5 entry (like 4 full days) and I'm quite proud of how it's... |

[4E5] Workspace pics
|
Post a pic of your workspace! This is where you can show off your awesome development system, and how close it is to your fridge. I got this idea from ludumdare 48h by the way.
Anyway, I guess I should start this off. So here it is, Junk Central (... |

Template classes in container
|
I'm having problems creating a map of templated classes. It seems to have no problem with the map itself, but doesn't like iterators for it. Here's as simple as I can get it:
template<class T>
class A
{
};
template<class T>

Disabling after trial
|
I'm working on a game in c++, and I got to thinking: how would I get it to disable itself after a 14 day trial? I guess I'd need to store the time and date it was installed in a file somewhere obscure, and check it against the current date. But... |

JIT compiled scripting language features
|
Hi,
I'm working on a JIT compiled scriptingish language thing, and it's got to the stage where need to think about what sort of language it's actually going to be. I'm not sure if it's technically a scripting language, but it's meant to be embe... |

Can't host a java phone game
|
I followed a tutorial here, and although I wasn't too impressed with how he'd hardcoded in the resolution, it was very helpful. But now I'd like to try it out on my new motorola E770v. So, I got compiled it and packaged it into a .jar, a .jad, a... |

Progressive texture loading

Since it seems to be the only thing I've done that makes people go wow I'm considering writing an article on loading textures (interlaced png specifically) over several frames. It's useful because you can load textures on the fly witho... |

JSRay - Realtime Preview Raytracer
|
Believe it or not, this works on android 2.2! (nexus one) It's impossible to navigate and I had to push render twice before it did anything, but it did render. Claims to have taken 28829ms.... But I really don't think it did. |

Faster Collisions Circles or Squares? Advice. (Fixed)
|
Ah, you want to test between hollow squares rather than solid boxes? I don't see why you need that for asteroids. Anyway, lets look at determining that they don't intersect. There are only a few options:
1. The squares are separated on t... |

Faster Collisions Circles or Squares? Advice. (Fixed)

For circles, you don't need the square root. Just compare the square of the distance with the square of the radius. You also don't need to make sure you're subtracting the smaller value from the larger when finding the distance, because if you do it... |

AngelScript JIT/AOT implementation details (technical)

Is there a reason you can't simply have the JIT code natively call a function which then executes the correct script function? So all calls to script functions in JIT code would be compiled as a call to this single wrapper function, with arguments de... |

Seed Random, Global objects, and SDL_Threads

There are several options.
Option 1: Pass anything you need to into the thread. That data pointer is there for a reason. You'd just have to do something like:
if (data == NULL)
; // Die horribly
EnemyShip* myEnemy = (EnemyShip*)data;
myEne... |

Quaternion, again
|
You shouldn't have to extract the x axis like you're doing. For an fps camera you should be able to just create quaternions representing rotations on the x and y axes and combine them in the correct order (I'm not sure which order that is, but... |

Quaternion to Euler

There are several different sorts of euler angle (you can do the rotations in different orders). Are you sure that both of your conversions deal with the same flavour? |

rendering with distance fields

That really is cool then! Can you give me any more info about how you've done it? CSG with primitives is straight forward enough, but I'd like to know how you managed the smooth surfaces and noise. I'd thought about noise before, but couldn't see how... |

rendering with distance fields

That's really cool! Do you generate the entire volume at program load? I ask because I've been working on a similar near realtime renderer, and the biggest issue seems to be memory usage. If you've come up with a way of representing the volume p... |

Time of intersection?
|
Swept test between circles is fairly simple. First, testing for intersection between 2 circles is the same as testing for intersection between a larger circle (radius r1 + r2) and a point. Say the point was moving and the circle was stationary. The p... |
