Physical basis of rendering

Hi!
I know this is possibly too theoretical for this forum, but I have had this sort of curious question in the back of my mind for some time and figured I'd share it with you folks to see what turns up.
In physics, light propagation is descr... |

Immersive Webcam VR Demo
|
Inspired by Johnny Lee's Wii Mote VR Tracker, I decided to try building a virtual reality display. Using OpenCV, I was able to get a comparable result with face tracking. The result is that you don't need anything other than a web camera for it to... |

The Quaternion Julia Set in MPI
|
A raytraced image of the quaternion Julia set written using MPI. The total computing time for this image was 30 minutes on a 96 processor cluster.

Other graphics forums?
|
Hey, it's been nearly 2 years since flipcode closed its doors and forums. Back when flipcode was in full swing, it was the place to go to get current graphics news and information. Nowadays, updates seem much harder to come by. GameDev.net is nice... |

Realtime Constructive Solid Geometry
|
Hello everyone! I've decided to post some preliminary results from my constructive solid geometry (CSG) work. Briefly, CSG is a modeling technique whereby models are built from set theoretic compositions of smaller models. The algorithm used in ea... |

Here are some screenshots from Professor Automaton's Cruel Legume Device, the result of our team software project. The game is basically Puyo Puyo, or Dr. Robotnik's Mean Bean Machine.
Features:
Practice mode
Hot seat multiplayer
Lots of AIs

MMORPG Alpha Client - In Development.
|
Wow! Really impressive work, and that is a surprisingly complete list of features for an indie MMORPG. |

Generating Polygons from Voxel Data?
|
You can also just construct a really simple mesh (ie just glue a bunch of boxes together), then do some surface subdivision to fair the result. |

Any tutorial about procedural modelling using c++ / HLSL?
|
Do you mean procedural modeling or implicit modeling? These are two very different things. Procedural models focus on generating interesting, or aesthetically pleasing content programatically. It can be at the same time an art, a science and... |

Research Project Ideas?
|
If you are into procedural generation, you should look up the texture synthesis stuff by Wei and Levoy:

It would also be worth your while to study Markov random fields models for signal processing.... |

Complete graphs that live on a closed 2D space of constant positive curvature.
|
This looks pretty neat, but if you don't mind me asking what exactly is going on here? I am somewhat curious about what/why you are drawing these pictures. |

Physical basis of rendering

I think I figured it out on my own. Here are some links which basically answer the question:

As a short synopsis, the theory that light... |

Physical basis of rendering
|
Pedantically, you are right; such models don't take into account quantum phenomena and so they are at least asymptotically unphysical, but this is not really the spirit of what I was asking.
I don't know if it was clear in the first post, but I wo... |

MMORPG - Needing talent

If you are really keen on doing sand simulation, you should probably spend some time getting up to speed with the current literature. It is really an open research question right now if sand physics can be done with reasonable fidelity on... |

Splitting A Polygon into Separate Triangles
|
The problem as stated is sort of ambiguous. If you just want to triangulate some planar polygon, then you can use a simple greedy algorithm: While the polygon is not totally covered, remove a triple of vertices contained in the remaining polygon.... |

Sparse Voxel Octree Ray-Casting

I just want to say that I think this is very cool and certainly one of the best IOTDs posted in a long time.
Though I am a bit curious as to how you managed to fit the whole voxel tree into the GPU. Do you use any compression besides elimina... |
