Mapping Depth Values to the near / far range
|
Hi,
I have a projection matrix that is
w, 0, 0, 0,
0, h, 0, 0,
0, 0, (f + n) / (f - n), -(2 * f* n) / (f - n),
0, 0, 1, 0);
This matrix is a OpenGL projection matrix. I would like to map the values that I can read from the depth buffer int... |

Cover circle with quads

Hi,
I would like to approximate a circle with quads. The quads should overlap the circle in a way that there is no area of the circle uncovered.
What I want to find is the best possible way to calculate the quad size and number of quads. Being abl... |

Attenuation / To figure out the Bounding volume of Point lights / Spot lights
|
Hi,
I was thinking about this now for a while. Using the classical attenuation function can make the determination of the size of a bounding volume quite complicated. This was covered in several threads in this forum so far.

Intel Graphics Media Accelerator 4500MHD

I am sure that this graphics chipset has some problems to run certain games fast enough, but what I would like to hear is if all DX10 features are really supported. I am not interested in speed just feature support. I don't care if my simple example... |

Reconstructing Position from Depth Data
|
Hi,
I am on my quest to figure out the fastest way to reconstruct a position value from depth data. Here is what I know:
1. If you stay in view space and you can afford a dedicated buffer for a separate depth value you can do the following (... |

That's quite impressive. I skipped through your thesis. You explain things very well. |

Next-next generation voxel data?
|
Quote:However, we still have largely fixed bandwidth from drive to memory, and from memory to cache. And this is the limiting factor: given a terabyte of voxel data, it is infeasible to move enough data across the bus quickly enough to render it. Wel... |

Next-next generation voxel data?

Next-next generation voxel data?
|
How can a technique that relies on so much memory access considered next-next-gen while computational power increases much faster than memory access and procedural generation of geometry is already here ... I don't get that :-) |

Exponential Shadow Maps

Hey Marco,

The following source looks like the linear approach you describe. It writes li... |

Skybox gradient distortion.

I spent a few fine hours debugging banding to find out that the TV was introducing the banding in the first place; try another TV or monitor e.g. notebooks might show you this kind of banding ... sometimes you have to give up :-) |

I read the chapter but it doesn't sound right to me either. I contact Fan ... maybe he can contribute to this thread. |

Global Illumination Honors project!

Hey Krokhin,
I tried your demo but it is not running for me. Crashes on the start-up screen. Can you explain what you did in there?
