Random numbers, different platforms
|
Hello!
Does anyone know of a simple random number generator (in C/C++), which have the following properties:
- Always generating the same sequence of numbers, independent of the architecture it's running on.
- Good randomness from a st... |

Jacobian matrix, ball joint

Hello people,
just playing a bit with inverse kinematics, but stumpled into a problem. The article I'm reading only covers setting up the jacobian matrix for 1DOF hinge joints and slider joints, but I'd really like to have some 3DOF ball join... |

Cross platform-friendly storage of floats
|
Hello.
Until now I thought I could just save my floats like this:
write_LE_int(*((int *)&some_float_var));
and read them back like this:
some_int_var = read_LE_int();
some_float_var = *((float *)&some_int_var));
where write_LE... |

OpenGL and software patents

Browsing OpenGL extensions at http://oss.sgi.com/projects/ogl-sample/registry/, I noticed that quite a lot of the extensions apparently are affected by software patents. To mention a few:

Game localization

Hello people,
I'm currently at the point where I plan my next game pet project. Early planning of localization is one lesson I learned the hard way from my earlier project - I didn't think about supporting anything else than english, but as t... |

How to render a floor and a ceiling for a portal engine?
|
Triangle fans and such usually only work with convex shapes. In case of your 'L' it's no longer convex but concave.
I don't know the details of Dark Forces and BUILD, but if they're like Doom as I imagine, they create a 2D BSP tree of the wal... |

GLSL Problem
|
Are you sure your ATI card supports all the GLSL features you're using?
Or maybe you've made a bug in your shader code which doesn't affect your nVidia card, but makes ATI's drivers fail.
Why you don't get an error message I don't know...
How... |

Random Number Generation Issue
|
It's because you for each cycle resets the random seed with srand() to the same value. Your loop is so fast that time() won't change before you've finished looping.
Simply call srand() outside the loop instead.
By the way, it's usually not a go... |

lua

I'm not sure I understand your questions correctly...
Is your first question when you should call lua_register()? If so, the answer is that you should just do it at any point before you execute the Lua script. A good place would probably be when y... |

Object Rotation
|
You need to first translate the object, and then you can rotate it - i.e. basically move the object so the pivot point is located at the center.
You can use glTranslatef(x,y,z) for that. |

SDL Mouse Usage

advanced 2D physics engine?
|
I think I've ranted about just using plain ODE for 2D physics before, but I'll happily do it again :)
To my experience, plain ODE works perfectly for 2D. Just keep all your Z-values zero, and everything just stays perfectly in the XY plane. Furthe... |

Good HTTP library?... few dependancies?

Personally I'd just use libcurl. Maybe implementing a HTTP GET directly with sockets is simple, but using libcurl you're absolutely sure it works. No wasted time on debugging.
The library is released under a MIT license (not as restrictive as G... |

How do I know if I have an Internet Connection?

I suppose that you only check whether you're connected to a network - i.e. if a cable is plugged into your network adapter and there's some kind of network equipment on the other end.
Basically it's hard for a computer to know how large a... |

Have you followed the instructions linked to in this FAQ? http://www.libsdl.org/faq.php?action=listentries&category=4#47
How exactly did you try to "import the stupid lib and include files into it"? |
