Graphing RGB Waveform (HLSL?)
|
I'm at a loss as to how to approach this. I'm using Direct3D9 and want to take an image, and for each vertical line of pixels create a graph that plots the red components of each of the pixels on a new image. So if a point on some image... |

Testing image processing pixel shaders

I'm looking at trying to test out some pixel shaders for shader model 3 that will be used as full-screen post-processing filters. Does anybody know of some easy to use software that is designed to process images using custom hlsl shaders that I can... |

Fast Direct3d MJPEG compression
|
Does anybody know of a fast (fast!) way to encode direct3d surfaces into jpegs? With slimdx and c# I tried texture.tostream and that seemed pretty slow..
This was also pretty slow and I didn't even get to the jpeg compression yet. Getrendertarg... |

[SlimDX, C#] Flickering Textures
|
Hopefully this is an easy one to debug based on description. Right now I'm rendering a number of textured quads each with their own vertex buffers to separate render target textures. The vertices almost never change.
Originally I had m... |

[SlimDX] Creating texture with shared handle crashes

I'm trying to create a render target texture to be shared between two devices using slimDX. Unfortunately I get the following error (Windbg) every time I try to create the texture using the August 2009 release of SlimDX. I'm using debug august 2009... |

[slimdx] Surface.FromBitmap

I'm attempting to load a bitmap already in memory as the background of a surface. I'm running into problems where the color looks more like a dark blue / purple rather than black.
I'm essentially trying to duplicate the MDX code "_surf = Surface.... |

Rendering windows on multiple monitors

I decided to create a new post for this particular issue since it is a different problem altogether (and one that I'm pretty concerned with that I don't really have options). I'm using a multi VMR9 setup where I'm rendering textures allocated f... |

[MDX] Rendering to Control created in other thread

First, I'm using C# MDX. I'm not sure what the general strategy here for rendering is. I created my render loop in a separate thread and I seem to be able to render to the Direct3D device I created just fine. I'm using the same device to present t... |

MDX/C# Struggling to understand problem..

I'm struggling to understand what I'm missing, and perhaps someone here knows something high-level that I'm not thinking of. In short, my live video that I'm capturing through directshow displays for about 10 seconds in a picture control and then go... |

- Will it work on non-IE browsers ,specifically Firefox & Chrome. (The current site has always been unreliable on these browsers for me.)
Great Job.

Our native resolution for the new site is going to be 1280 pixels wide but that will also be a fixed resolution so on wide-screen monitors the site will not scale to the edges of the screen. It is very difficult to control the look of a site wi... |

I'm not sure of exact figures but generally it's in the thousands of dollars per month range to run the site. Not only do we have pretty hefty server bills but in order to keep getting advertisements and sponsorships we have to pay sales people... |

There is a big different between "doing damage" and "not helping". People who block ads are "not helping". Using the other language implies they are taking a sledge hammer to your server. (Again, if ad-blocking is s... |

Two possible approaches come to mind:
1. If you're targeting hardware that supports efficient vertex texturing (basically any DX10-capable hardware), you could just have a line or point list with the number of vertices... |

DirectShow, something wrong with PREVIEW pins
|
Just a note though that capture pins don't drop frames if things get hairy and start falling behind.. Capture pins are for actual perfect video captures, not previewing. For webcams you probably still want to use the preview pin.

Testing image processing pixel shaders

I was using this only because it seemed much easier vs Nvidia's solution which isn't specific to image processing.

De-interlacing in a shader

I'd be very interested in your work as I'm trying to come up with an hlsl deinterlacer as well but just haven't gotten around to it.. I would think you would need at least two images to do deinterlacing. Use the code below to decimate odd fields, b... |
