Precalculated Occlusion

I've been working on a 3D engine for the new and improved Flash 9 which is fast enough to handle simple textured scenes. Despite the new speed however, plotting pixels still comes at a high cost because there is still no direct array access.

Patent issues, especially fluids
|
Hello, I'm interested in using the Fluid Dynamics for Games paper in a small commercial application, but despite a lot of Googling I'm still unclear on exactly what is patented, for example is it only in combination with the FFT that the pa... |

Stam NSE solver optimizations
|
I've read a few times (I can't remember where) that the code in Stam's fluids paper can be greatly optimized, I assume this concerns the relaxation. Does anybody have any insight into this? Mine is a GPU implementation if there's any shader trickery... |

HLSL Image Sampling
|
Hi,
I'm taking a bilinear sample from an image, but I'm without VPOS because I'm on shader 2.0. Converting to integer values gives inaccuracies and creates banding on the image, is there a more efficient and accurate way to do this? |

Real-time planet rendering

I don't have formal mathematics education so it would take me a while to decipher the paper, but it looks so good I'm thinking about it. |

Good stuff!
Can you offer any tips on getting all the noise out of your SSAO like that? |

Advice for using a patented cg-method

I ran up against this too, I mailed Stam and didn't even get a straight answer, he just said they weren't interested in allowing anybody to use their patented algorithms.
This conclusion I came to is that the patent text uses an FFT to resolve th... |

Looks pretty cool. I would love to know how you made the grass effect!
Mine didn't look as good as these but I didn't get around to finding out why.

FFT is another patented algorithm.
Nope.
The original FFT algorithms were from Gauss in the very early 1800s. Those certainly aren't covered by patents.
Ah, I was reading the te... |

getting a simple answer is impossible anymore

A vector is a group of numbers (scalars), a vector with two scalars can indicate a position on a grid, one scalar indicating how far along the grid, and the other how far up, in other words the X and Y values.
Imagine two vectors with di... |

I was planning to do this fully geometrically by finding everything visible from within the cell volume, rather than finding everything visible from any of the corners of the cell.
That's what it does, the corners ar... |
