[C#] Fastest way to zero out an array?
|
I'm currently working on a little XNA project that requires me to clear a few large arrays each frame. The arrays are backing stores for textures, so they have up to millions of elements, and they're constructed from a generic type parameter (... |

[XNA] GPGPU library and questions
|
As I mentioned in my Water Cube topic, I'm working on a little XNA library for doing general purpose calculations on the GPU. The library is simple, but I think it's also fairly simple to use and drop into XNA things. If anyone wants to g... |

Water Cube

These are some screenshots from a little demo I'm working on, a Water Cube. As requested here and here are the videos on YouTube.
I've been meaning to code this since I saw the Unreal meatcube video. Recently I wrote some code that would... |

JScience library, status and possible bug

I'm hoping someone here is using the JScience library. I'm currently porting over some code from it to C#, specifically for an astronomy pet project. Now I found that the "V2" branch no longer seems to include the astronomy package, but then again... |

[XNA 3.0] User resize of window, GameComponents and LoadContent
|
It's been a while since I've been tinkering with XNA. I'm still on XNA 3.0, but I guess this particular mechanic works the same for 3.1. I think I've gotten rusty and even more verbose though, so please bear with me [smile]
Anyways, o... |

Is GDNet molesting casing in "Style"?

Heya,
Sorry to come right back with a nitpick after being AWOL for a bit, but I ran into an issue with a simple code snippet I posted over here. I edited that [ code ] block a number of times to correct the casing (style should start with u... |

Publishing RSS feeds to journals

I couldn't find if this was already brought up, but I was just thinking it might be a useful feature if user journals could be 'fed' entries by RSS feeds from other sites, in addition to manual postings. In this day and age everyone and their dog h... |

VS Settings, persisting Application scoped settings not possible?

Instead of stubornly coding my own stuff like I usually do, I decided to give the Settings feature in Visual Studio a try for a little standalone app of ours. It works quite well, but I found it doesn't seem to store any changes to Application scop... |

Windows Phone 7 - who's gonna get one?

Although not really compelling, I'd be happy with a WinMo6 type of phone with actual graphics capabilities. I've always enjoyed tinkering on my Windows Phones (unified GPS ftw!) but I kinda fear there will be some restrictions in place that we... |

Good news, XNA will set up all the basics for you [smile]
I haven't got any XNA books so I can't personally recommend any, but the resources available on the XNA site itself (the 'education catalog') should at least get you started.

Shader pipeline differences OGL DX

IIRC it was mostly setting uniform data, like matrices, model colours, etc... Without effects we put this data into specific registers, so they don't have to be re-uploaded with each shader switch.
Thanks for the re... |

I do quite like the changes where something hasn't been removed.
Which changes would that be for a PC user? To be sure, I'm not challenging you to defend anything, I'm just curious. For me personally moving up to... |

All things are the same but render result
|
Well, if the data & states are the same, it'll be hard to point out what can be causing this. Isn't there anything different at all between the two cases? Maybe something a bit more remote from the rendering, like a missing texture or alpha map?

XNA 4.0 near broke me spirit!

We had much the same discussion just a few days ago and I'm ok with sticking to XNA 3.1 for my PC projects, more so since much of my codebase is also in 3.1 and it looks like a pain to migrate. However...

vertex structure for skinned mesh

The struct looks fairly standard to me, only the typical number of bone influences seems to be 4 per vertex, allowing you to use float4's in your shader's vertex structs. I'm getting the impression you're unsure about how this is meant to work t... |

I can then create stars at random positions, test them against the density, and add the ones that pass a probability test to the scene.
You might be better off testing a uniform grid of positions against the... |
