[D3D11] Append Buffers and Copy Structure Count
|
I have been building up a particle system using append and consume buffers where all of the particles are read out of a consume buffer, they get updated, and then appended to the output buffer. This is currently using a fixed number of particles for... |

[D3D11] Append / Consume Buffers
|
I'm beginning to dabble in the Append / Consume buffers in Direct 3D 11, and am not quite sure how exactly they work... The docs mention that the Append buffer has an 'append' method to add elements to the buffer, and the Consume buffer has a 'consu... |

Windows Kinect Driver?

I have seen the open source Linux drivers for the Kinect cameras, but haven't seen any Windows based open drivers yet. Am I missing something, or have they not sprung up yet? I don't have a Kinect yet, but would still like to take a look at the dri... |

[D3D11] Geometry Shader Input Vertex Ordering

I am trying to figure out what order the vertices passed into a geometry shader are supplied in... I haven't been able to find it in the docs, and it seems that geometry shaders are as popular with the tutorial writers... Does anyone know of a plac... |

[D3D11] Compute Shader Memory Barriers

In the past, I have used GroupMemoryBarrierWithGroupSync to synchronize all of the threads in a group after filling the group shared memory with a bunch of texture data loaded by the individual threads. After that call, I was assured that the writin... |

[D3D11] Multithreaded Command Lists

Lately I have been working on my multithreading implementation for Hieroglyph 3. It is going quite well, and I have the engine automatically handling multithreading at the "view" level - i.e. one command list is generated for each complete... |

Hieroglyph 3 Rendering Engine
|
For those who are interested, I've recently created an open source project out of my Direct3D 11 renderer named 'Hieroglyph 3'. You can find the project page here.
The project is still in its early stages, but the renderer interfaces are fairly... |

[SOLVED]Never-Ending Message Pump

I was recently reading over one of the Evil Steve tutorials, and realized that I wasn't clearing out the windows message queue every time around (as he suggests). However, once I converted my code from this:

D3D11, DXGI, and Multisampling...

I've been using D3D11 for quite some time now, and have just started trying to enable multisampled rendering. I haven't found much information in the documentation that really clarifies exactly how you are supposed to specify and/or use a multisampl... |

[DX10/DX11] Texture Load vs. SampleGrad

Lately I have been doing quite a bit of work with compute shaders on DX11, running on my Geforce 8600M. With DX10 level hardware and some updated drivers, I can run in real time and test out my algorithms without much trouble. During some... |

D3D11 and font / text
|
MJP (Matt Pettineo) added a text rendering system to my engine: Hieroglyph 3. You should be able to grab the relevant classes and borg them into your own code.
Also, the engine is available under the MIT license, so you can take a look around ins... |

MultiScreen Rendering - Perspective Issues
|
If you are using D3D 10/11 then you can use the SV_ViewportArrayIndex to send geometry to multiple viewports if you need to. However, I would just render to a single offscreen buffer then copy the relevant portion to each screen area. I haven't use... |

Yes - the triangulation / tesselation problem once again...

I don't know what formal paper you should read, but I would suggest starting with a regularly spaced grid of vertex locations. Then generate a set of triangles based on the closeness of the vertices to one another. Then iterate on th... |

Using Back Buffer as Shader Resource View
|
Quote:Original post by Erik Rufelt
As far as I know, you can't sample a resource that is currently bound as a render target. You need to draw to a separate render target to sample what you have already drawn.
This. You can't read from a resource t... |

Using Back Buffer as Shader Resource View
|
Are you trying to sample it after you have already presented the contents of the frame to the window? If so, then you are actually sampling the other texture resource that the swap chain supplies for double buffering.
Are you also getting any de... |

MultiScreen Rendering - Perspective Issues

If the screens are all coplanar in their positions, then a single render target can be used to represent the contents of all three monitors. It is only after changing the orientation that you would need to create separate rendering passes for e... |

[DX11] Handling Multiple ResourceViews with Multislotted Resources

I'm not sure if the runtime will let you do that or not. At the very least, I would expect a warning when you actually execute the draw call that would use the texture.
When you create an SRV you specify the view dimension, which has distinct ent... |

[DX11] Handling Multiple ResourceViews with Multislotted Resources
|
The difference between Texture2DArray and Texture2D[n] is the the Texture2DArray is a single resource with multiple subresources referred to as texture slices. A Texture2D[n] is just an array of individual, independent resources.
The other thing... |

GPGPU Algo Performance Characteristics

I don't recall seeing such a thread, but there isn't a definitive answer to the question since it depends on how a particular GPU operates. We have a chapter on image processing in our forthcoming D3D11 book that considers a few different... |

Using graphics technology to create unique styles more

I found your blog entry quite interesting. However, I think you are asking a somewhat obvious question - the reason that people aren't trying these styles out is that they aren't really readily available. It is kind of like saying "why didn't... |
