MineCraft - Real-time Path Traced
|
I suppose everyone has played MineCraft by now. :) So have I, and I was wondering how MineCraft would look if you would keep the data, but replaced the renderer.
These screen shots have been generated using a stochastic ray tracer / path tracer,... |

Raytracing and Global Illumination

This is an image from my real-time ray tracer, Arauna. Over the past monts, I have been working with Roel Reijerse to add global illumination to it. We implemented a sort of a 'static irradiance cache': As a preprocessing step, a fixed set of points... |

Image of the day

People,
I have a small comment on the IOTD mechanism: Today, an iotd that I posted four days ago was added to the gallery along with 5 others. This is not ideal. I suspect that most people primarily check the three images on the front pa... |

MineCraft - Real-time Path Traced

I was thinking about doing that per tile as well, definitely makes sense. I'm not sure if I want to take this beyond raw rendering, but if I do I will consider that.. Let me know if you want to take my code and add the gameplay, I would be more than... |

Ray tracer performance
|
Ah but that CPU doesn't even have SSE2... In that case you can't even compile Arauna yourself; it has tons of hand-written SSE2 code. Sorry about that. Then again, your CPU is ancient, you should be grateful it still works. ;) |

Ray tracer performance
|
Arauna doesn't use a GPU at all. 800x800 @ 30fps would require (depending on the scene) a quadcore processor, ideally an i7. With one of those that performance level is not too hard to reach. Brigade does use the GPU, but it's a path tracer... |

Check this forum: http://ompf.org/forum . It's all about ray tracing, with an emphasis on real-time. Quite some ompf members lurk on GameDev too btw.

KD-Tree traversal (traytracing) am I missing a case?

Hm, I'm not a C++ expert, so someone will probably correct me, but here we go:
If you have only a small recursive function, then you are doing tons of function calls compared to the actual work load. A function call is not 'free': a stack fra... |

KD-Tree traversal (traytracing) am I missing a case?
|
Are you trying to figure out how to traverse a kD-tree yourself? You may want to check out Wald's work, or Vlastimil Havran's thesis. They both provide tiny algorithms for kD-tree traversal. Yours is too complex.
On a sidenote: Implement your own... |
