DX11 Perspective Matrix Jittering Temporal AA
|
I recently became aware of temporal AA after hearing about it from a couple of sources. Crytek mentioned in their Siggraph 2010 presentation that they were using a hybrid AA solution consisting of edge-detection posteffect AA for nearby objects and t... |

DX11 DirectCompute Buddhabrot & Nebulabrot Renderer

Hi everyone, I wrote a DX11 DirectCompute Buddhabrot/Nebulabrot fractal renderer. The submitted picture is a Nebulabrot with max iteration values set to red:391 green:781 blue:10156. I rendered the above image (original image was 1592×1028) at around... |

Interesting work! Thanks for the demo.
In case you are curious how it runs on other ppl's machines, here's the numbers for my HD5750 (Catalyst 10.10a).
bilateral distance texture - around 1.55-1.6ms
scan edges in shaders - 5.45-5.5ms

I posted a pic of what the grid texture looks like with mipmapping & trilinear filtering working properly. If anisotropic is used the blurring becomes gone too.

You are right. I didn't understand the anisotropic filtering you were referring to properly. Turned it to 16x and aliasing becomes pretty clean.

Good point about mipmapping and anisotropic filtering. I wasn't really careful with those settings. I tested with mipmapping and anisotropic filtering enabled, and the above grid texture still gets aliased pretty badly.
Texture filtering and mipma... |

Hey, thanks for the comments. Sorry about the images being small. I should have uploaded a non-cropped version of the images. I've posted the original sized images in my Japanese blog http://d.hatena.ne.jp/yakiimo02/20100926/1285523408.
The point... |

[updated] DirectX 11 auto-exposure controlled HDR and an auto-focus depth-blur effect
|
Compiled in release mode w vs2008 & ran it on my HD5750. With default cam pos & screen res of 720x405, fps seems to fluctuate around 300-420 fps.
Looks nice!

Hi everyone. Thanks for the comments!
@Inigo Quilez
As I write in the linked blog (relevant links #3), I got the idea for cubing luminance in order to bring out more contrast after reading your Buddhabrot page. Thanks a lot. It made a huge differ... |
