  • Pre baked fractures and explosion : I need an answer for C++

    - by Ken
    What are the prebaked or precomputed explosions or fractures from a programmer viewpoint ? I would like to know how to achieve this in C++ and how this things are usually considered (they are animations? textures?), it would be perfect if there will be some examples available or someone that can picture a broad view about this. I need to add a really small support for this in my code and i need an hint about how to start, i would like to do this on my own without other libraries.

  • Control Media via Arduino

    - by Ohad
    I want to create an application that controls the volume, play next\last, stop\play and things like this (I don't know what they called) like in a keyboard. I have tried to find how to do this with Python\Java but I couldn't find how. The main idea is (if some-one knows what is arduino) to connect it to my PC (Ubuntu) and to get from it signals that gives me values and with this values to be able to change the volume and to do next song\video. Thanks to any one who help :)

  • How does opengl-es 2 assemble primitives?

    - by stephelton
    Two things I'm quite confused about. 1) OpenGL ES 2.0 creates primitives before the vertex shader is invoked. Why, then, does it not automatically provide the vertex shader the position of the vertex? 2) OpenGL ES 2.0 supports glDrawElements(), but it does not support glEnableClientState() or GL_VERTEX_ARRAY, so how can this call possibly be used to construct primitives? NOTE: this is OpenGL ES 2.0, NOT normal OpenGL! Thanks!

  • Why are graphics so slow/jerky/lagged with an ATI 4250?

    - by Ben
    Never had a problem with Maverick, always very fast. I upgrade to Natty and the graphics seem to be very lagged. CPU, load, and memory usage is low, all graphics are choppy and lagged though. I have the proprietary driver installed and everything. Alt-Tabbing takes 3-5 seconds for the dialog to popup, zooming in with compiz zoom makes things very slow. I never had any of these problems with 10.10 Thanks

  • Is a subdomain per service a good idea for SEO?

    - by Kennie R.
    I am creating a site with quite a few services, such as a free account service, and of course a subdomain for my site's blog and then for article base and other related services, would having them all on subdomains be a good idea? Are there any caveats you are aware of in existing search engines for this? I believe mapping foo.example.com to example.com/foo to provide an alternative just in case is a good idea for sitemaps, I like to keep things clean.

  • Legitimate use of the Windows "Documents" folder in programs.

    - by romkyns
    Anyone who likes their Documents folder to contain only things they place there knows that the standard Documents folder is completely unsuitable for this task. Every program seems to want to put its settings, data, or something equally irrelevant into the Documents folder, despite the fact that there are folders specifically for this job1. So that this doesn't sound empty, take my personal "Documents" folder as an example. I don't ever use it, in that I never, under any circumstances, save anything into this folder myself. And yet, it contains 46 folders and 3 files at the top level, for a total of 800 files in 500 folders. That's 190 MB of "documents" I didn't create. Obviously any actual documents would immediately get lost in this mess. My question is: can anything be done to improve the situation sufficiently to make "Documents" useful again, say over the next 5 years? Can programmers be somehow educated en-masse not to use it as a dumping ground? Could the OS start reporting some "fake" location hidden under AppData through the existing APIs, while only allowing Explorer and the various Open/Save dialogs to know where the "real" Documents folder resides? Or are any attempts completely futile or even unnecessary? 1For the record, here's a quick summary of the various standard directories that should be used instead of "Documents": RoamingAppData for user-specific data and settings. This is the directory to use for user-specific non-temporary data. Anything placed here will be available on any machine that a given user logs on to in networks where this is configured. Do not place large files here though, because they slow down login/logout in such environments. LocalAppData for user-and-machine-specific data and settings. This data differs for every user and every machine. This is also where very large user-specific data should be placed. ProgramData for machine-specific data and settings. These are the same regardless of which user is logged on, and will not roam to other machines in a network. GetTempPath for all files that may be wiped without loss of data when not in use. This is also the place for things like caches, because like temporary data, a cache does not need to be backed up. Place your huge cache here and you'll save your user some backup trouble. "Documents" itself should only ever be used if the user specified it manually by entering a path or selecting it in a Save dialog. That is the only time it is ever appropriate to save stuff in "Documents".

  • Nvidia driver overscan issue second monitor via dvi-d cable

    - by benmichael
    Ok, I know that I have a bit of a bizarre setup, but here goes. I have an old laptop, HP Pavilion 6000. The graphics card in there is a GeForce 7150M. The monitor connection is an old 18pin. The external monitor I use is a Samsung SyncMaster 2333. Don't ask me why, but this monitor only has a dvi-d connection (yes, i have searched it). So I have the monitor plugged into the laptop. If I use any of the Nvidia propriety drivers and try to set the resolution up to 1920x1080 (the monitor's native resolution), I get a massive overscan issue. Over the years I have tried to get this to work, tinkering with my xorg.conf to death. I have also tried this on every Ubuntu since 10.04, on all the corresponding LUbuntus, and on all the Linux Mints since Lisa. Exact same issue. I have even tried it in WinDoze and it works perfectly there (although I did get the error once, but was unable to reproduce it). Using the Open Source drivers it works perfectly iff I switch off the laptop monitor (this makes no difference with the Nvidia drivers). I would have happily gone on using the Open Source drivers, except that since upgrading to LUbuntu 12.10, the Open Source drivers make my monitor completely hazy and have the same overscan issue until I (through the haze, only because I know where things are) go to the monitor settings, activate the laptop's monitor, then deactivate it, and suddenly it comes right. I have to do this every time. So I have to find a way to fix one of them, so I may as well tackle the propriety drivers, hence this overlong question. Amidst other things, I have tried the nvidia-settings, but because it is connected to an 18pin, it detects the monitor as a vga monitor and does not give me overscan correction options. I have tried custom modlines (although there are always more of those try), I have tried using xrandr, and I have tried all the FlatPanelOptions. What I have not tried is a Gentoo build, as I don't have time any more to do that installation, but up to about three years ago when I ran Gentoo exclusively I did not have this issue. Below is an link to an image with a red highlight around the portion of the screen visible to me, the numbers around it are the number of pixels which are cut off. This does seem to drift a few pixels every now and then. Thanks in advance. Nvidia driver issue image

  • Calculating Hit Accuracy score in a game

    - by N0xus
    I'm currently in the process of making a scoreboard for my game. One of things I would like to display is the players accuracy in the amount of hits they had in game. However, I have never done this before and I've no idea how to go about doing this. Is there a commonly used algorithm out there that can help me calculate this, or has someone found a way to calculate this fairly easily? Any help with this would be appreciated.

  • Mouse Not Working Properly

    - by James
    I just did a clean install of Ubuntu 11.10 but for some reason the mouse isn't working properly. Problems I'm experiencing are: left button on the mouse doesn't work, the cursor doesn't highlight anything, as well, the right side will not do a double click function. Doesn't seem to bring up the mouse menu to "go back" as well, "go forward" options. In order to make things work, I have to use the Enter key, and arrow keys.

  • Does a good programmer need to have good spatial sense?

    - by user297318
    Do you need to have good spatial sense to be a good programmer? I have next to nothing of it (I think it has to do with the differing vision of my eyes). I've already coded quite little things but wonder if this interferes with the ability to 'imagine' the assembly of the code in case of a more complex program? Sorry for my english, I'm Austrian and not so used to write in English.. Thanks for your ansers..

  • How can I set up the Trusty Desktop ISO for preseeding?

    - by user288087
    With Precise, I used to create a USB stick using the so-called "Alternate" installer DVD with my own preseed.txt, update isolinux/txt.cfg with a new menu item that would pass my preseed file on the command line, and watch as the installer happily did all the right things to create a Ubuntu install on the hard drive of the machine I booted. With Trusty, the 'alternate' image has disappeared. Is it still possible to preseed a Trusty install, and if so, how do I get the d-i/ubiquity system to use my preseed file?
