D3D11: Adding Custom Messages to PIX's log
|
Hi
I'd like to add custom messages to the log that can be created when using PIX and a debug-context. I thought that ID3D11InfoQueue would allow this, but it seems not to work. Also D3D9 seemed to have BeginEvent / EndEvent calls to group batches... |

D3D11: Creating 3D textures with format DXT5 / BC3
|
Hi there
I am trying to load a 3D texture into D3D that is compressed using the DXT5 / BC3 format.
I have successfully loaded it into OpenGL, where the NV_vtc extension explicitly defines how to do this (see here: http://www.opengl.org/registry... |

Making an extensible 3D editor
|
Hi
I have an editor to create levels for my 3D engine. I am mostly quite happy with it, but over time more and more functionality is added, making it harder to maintain and making compile-time quite long.
So far everything is statically compile... |

[D3D11] How / when to properly destroy a Vertex-Buffer ?
|
Hi
I have stumbled upon an annoying problem:
For text-rendering and some other stuff, i use an abstraction that creates vertex and index-buffers on the fly, issues the drawcall and then destroys the buffer again.
Now i found out that de... |

[D3D11] Equivalent for glBlitFramebuffer ?
|
Hi
I'm porting some OpenGL code to D3D 11 and stumbled upon an annoying problem:
There seems to be no equivalent function for glBlitFramebuffer in D3D. All i want to do is copy/blit a texture into another texture. In D3D11 i found ID3D11DeviceC... |

D3D11: Create Input-Layout without vertex-shader blob
|
Hi
Is there a way to create an input-layout without having the vertex-shader's blob around?
At run-time i can query the current vertex-shader, but it seems there is no way to use that to create an input-layout.
The simple problem is, that... |

SSE Performance

Hi
I am currently learning a bit of SSE(2) programming, using intrinsics.
As far as i can tell from searching these forums and Google, it seems to be a common misconception, that SSE is generally faster than x87 code. One article mentioned,... |

D3D11: Creating 3D textures with format DXT5 / BC3
|
Ok, I found it out.
D3D does not use the same format as OpenGL for compressed volume textures. Instead simply each slice of the volume is compressed like a normal 2D texture. No data rearrangement is necessary.
Then the sysmempitch etc. are as... |

D3D11: Creating 3D textures with format DXT5 / BC3
|
Yeah tried all that, doesn't work.
The problem with 3D textures is that they are stored as 4x4x4 blocks, so one "line" would actually be a slab (or volume) and it is not intuitive how the "line" and "slice" are then to be considered.
And s... |

[D3D11] How / when to properly destroy a Vertex-Buffer ?

Yeah, i have implemented a queue now, where the resources are destroyed with a 1 second delay. It works. But it feels hacky. |

[D3D11] How / when to properly destroy a Vertex-Buffer ?

The thing is that the library that implements the allocating/storing/rendering is not meant to be used for high-performance rendering. Its only purpose is to make it quick and easy to get something on screen. It implements a rendering s... |

[D3D11] Equivalent for glBlitFramebuffer ?

I usually only want to make an exact copy of a depth-texture, such that i can make a snapshot of the current depth-buffer and use it for later render-passes as an input-texture. I am a bit surprised, that even an EXACT copy of depth-stencil text... |
