Atmospheric Scattering and dark sky
|
Hello,
I am trying to implement atmospheric scattering effect based on O'Neils implementation from GPUGems2. Almost everything seems to be fine, but the sky colour is too dark. I already spent several hours trying to understand the problem an... |

Shader cache
|
Hello,
I would like to implement a shader cache which will store all compiled shaders in a file. Shader will be re-compiled if source file has been changed - otherwise compiled shader will be used directly from the cache file.
I am not very fam... |

[solved] Detecting debugger

Hello,
I would like to add a special dialog box to my assert function which will show different information depends if the application runs under Visual Studio or not. Does anyone know if there is a function in VS which I can use to detect the deb... |

MRT support
|
Hello!
I am working on my 3D engine and some time ago I implemented Deferred Rendering. I am using 4 surfaces with different formats:
- D3DFMT_A16B16G16R16F (HDR color) - 8 bytes/pixel
- D3DFMT_A8R8G8B8 (normal, specular) - 4 bytes/pixel

MRT and multisampling
|
Hello,
I am using deferred rendering in my 3D engine which is based on DirectX9. I would like to improve a quality of my final image by using anti-aliasing. I know, that in the past it was not possible to use multisampling with multiple rende... |

Hi!
I am finally done with my demo called "Project 2501" on which I was working in my spare time for a couple of months. Demo is using my own graphics engine. Main features are:
- easy to use shader system providing following effects: bump... |

Hardware instancing

Hello,
I implemented hardware instancing in my 3D engine and I am getting some performance issues. My test scene contains 100 objects and each one has 30k triangles, so in total I am rendering around 3M triangles. Without instancing I am gett... |

Antialiased image and capturing video
|
Hello,
I want to capture video from my DirectX application, but I have one problem. I need to access back buffer data. I can do this by creating off screen surface in system memory and in each frame copy back buffer to this surface. Then I ca... |

Antialiased render targets

Hi!
I want to render my scene to 2 render targets (surfaces) by using SetRenderTarget(). Everything works fine when I am not using antialiasing, but if I set multisampling type different than D3DMULTISAMPLE_NONE then nothing is being rendered to m... |

Depth in perspective shadowmap

Hello,
Currently I'm working on shadows and I have one problem with perspective shadowmaps. I'm rendering my scene from light position to special depth texture. I would like to have linear distance from light to all objects (pixels). In... |

NFAA - A Post-Process Anti-Aliasing Filter (Results, Implementation Details).

Yes, you are right. The vector should be only scaled by variable called "filterStrength". |

NFAA - A Post-Process Anti-Aliasing Filter (Results, Implementation Details).

Hello Styves,
Thank you for helping me :) Your code was very useful. I only modified it a bit and I implemented normal scale/offset based on pixel distance from the camera. With fixed scale/offset I was getting some artefacts in the dist... |

NFAA - A Post-Process Anti-Aliasing Filter (Results, Implementation Details).

Hello,
I was looking for a good anti-aliasing technique for my deferred rendering for a long time. Your idea sounds very interesting and I would like to test it in my engine, but I am not sure if I fully understood how it works. How exactly do you... |

Shader cache
|
The only reason why I was thinking about shader cache is to avoid run-time stalls.
And no, I can't compile all shaders at a start up of my app, because as Hodgman said, that would take too much time. I have around 5 "super shaders" and every... |

Shader cache
|
I am a bit surprised that it's not possible to load a shader in a binary format, because as I know it's not a problem under DirectX.
Anyway, thanks for the answer. |

Shader cache

My application uses many variations of several shaders and I need to access them at any time. For example - if I enable a point light, then several shaders need to be re-compiled to include point light computations. Currently it stops the whole appli... |

Thank you. I will test that.
I am using GeForce 9800GX2, but I also tested my engine on 8800GTX.

MRT and multisampling

Thank you very much. For now I will use supersampling and probably in a near future I will start porting my 3D engine to DirectX 10.

Hardware instancing

Thanks for the reply. Also one of my first ideas about poor performance was to modify the pixel shader, so I changed it to output singe color, but it didn't help. My application runs at around 40FPS, because in my test scene I am using HDR rende... |
