  • How to attach two XNA models together?

    - by jeangil
    I go back on unsolved question I asked about attaching two models together, could you give me some help on this ? For example, If I want to attach together Model1 (= Main model) & Model2 ? I have to get the transformation matrix of Model1 and after get the Bone index on Model1 where I want to attach Model2 and then apply some transformation to attach Model2 to Model1 I wrote some code below about this, but It does not work at all !! (6th line of my code seems to be wrong !?) Model1TransfoMatrix=New Matrix[Model1.Bones.Count]; Index=Model1.bone[x].Index; foreach (ModelMesh mesh in Model2.Meshes) { foreach(BasicEffect effect in mesh.effects) { matrix model2Transform = Matrix.CreateScale(0.1.0f)*Matrix.CreateFromYawPitchRoll(x,y,z); effect.World= model2Transform *Model1TransfoMatrix[Index]; effect.view = camera.View; effect.Projection= camera.Projection; } mesh.draw(); }

  • Dual boot problem - Ubuntu windows 7

    - by Benoit Roberge
    I've been using Ubuntu for a while on my laptop. Recently, I decided to install Ubuntu on my main desktop PC (dual boot with windows 7). I downloaded the Ubuntu installer for windows and installed it (it's now showing Ubuntu in the installed software in my W7 control panel). However, when I tried to boot Ubuntu, after the boot loader and the login screen, my screen splitted in half. I was not able to see the icons and the launcher. I was also not able to do anything. I uninstalled Ubuntu and tried again twice. Same thing/results. Then, I created a partition in W7 and installed Ubuntu on it. Unfortunately, it's doing the same thing. I never saw something like this. Any idea??? Thanks for your help and support.

  • Android, OpenGL and extending GLSurfaceView?

    - by Spoon Thumb
    This question is part-technical, part-meta, part-subjective and very specific: I'm an indie game dev working on android, and for the past 6 months I've struggled and finally succeeded in making my own 3D game app for android. So I thought I'd hop on SO and help out others struggling with android and openGL-ES However, the vast majority of questions relate to extending GLSurfaceView. I made my whole app without extending GLSurfaceView (and it runs fine). I can't see any reason at all to extend GLSurfaceView for the majority of questions I come across. Worse, the android documentation implies that you ought to, but gives no detailed explaination of why or what the pros/cons are vs not extending and doing everything through implementing your own GLSurfaceView.Renderer as I did Still, the sheer volume of questions where the problem is purely to do with extending GLSurfaceView is making me wonder whether actually there is some really good reason for doing it that way vs the way I've been doing it (and suggesting in my answers to others to do). So, is there something I'm missing? Should I stop answering questions in the meantime? Android openGL documentation

  • Loud fans despite cool system under Linux (but not Windows)

    - by Sman789
    My new desktop computer runs almost silently under Windows, but the fans seem to run on a constantly high setting under Linux. Psensor shows that the GPU (with NVidia drivers) is thirty-something degrees and the CPU is about the same, so it's not just down to Linux somehow being more processor-intensive. I've read that the BIOS controls the fans under Linux, which makes sense given the high fan speeds when in BIOS as well. It's under Windows, when the ASUS AI Suite 3 software seems to take control, that the system runs more quietly and only speeds the fans up when required. So is there a Linux app which offers a similar dynamic control of the fans, or a setting hidden somewhere in the ASUS BIOS which allows the same but regardless of the OS? EDIT - I've tried using lm-sensors and fancontrol, but pwmconfig tells me "There are no pwm-capable sensor modules installed". This is after the sensors-detect command does find an 'Intel digital thermal sensor', and despite the sensors working fine in apps like psensor. Help getting this to work would likely solve the problem.

  • How do I shutdown 12.10 when ACPI is set to OFF?

    - by rahi
    I recently installed 12.04 on an HP Spectre XT ultrabook. I installed 12.04 from a USB. When the install was complete, and the computer restarted, I got a blank screen. After some searching, I found that I had to choose "acpi=off" during the installation, which now shows up in the grub screen. Once I was on 12.04, I upgraded to 12.10. The issue now is that when I hit shutdown, the computer hangs on a purple shutdown screen. Usually, at this point, I press the power button on the machine to completely power off the machine. I am new to ubuntu, and would appreciate the help. Thanks.

  • Is it possible to sync two computers without storing the files on a server?

    - by William
    I have a family member currently using Windows live mesh to sync a relatively large amount of files between computers. It is way over the Ubuntu One 5 GB limit and the Live Mesh 2 GB limit. However, Live Mesh gives him the options of syncing all the data he wants without storing it on Microsoft's servers. Does Ubuntu One have an equivalent option, performing just the sync computer-to-computer and not computer-to-server and server-to-computer? Do you have other recommendations? It does not necessarily have to be Ubuntu One, but I need it to be cross platform, working across Windows and Ubuntu. We also have computers outside of uour home network we need to sync to. This is one of the few things keeping him from switching to Ubuntu, and I'd be very grateful for any help.

  • How to get the correct battery status?

    At this moment, ever since I installed Ubuntu on this machine, the battery status says: not present.

  • Communicating with a remote host via HTTPS

    - by user619818
    I have developed a solution where a Java applet makes a socket connection to a port on a socket server (which happens to run on a web server). But a new client has implemented https within their LAN and so I am told communication must be via HTTPS. With standard socket communication you connect to a port on a host. But the clients HTTPS uses port 443. So will it be possible to connect to a socket server using a different port? I assume it must be possible? Any help would be much appreciated.

  • Will many links to the same page without nofollow penalize the host site in the search engine rankings?

    - by Evgeny
    May be a silly question, but I'll give it a shot :). On my forum app I would like to allow users with sufficiently high reputation display links to their home pages under every post - without the nofollow attribute (while lower rep users will have the nofollow) I am happy to help the site contributors improve rankings of their own, but not sure if this can actually deteriorate the rank of the host (the site that hosts those links) - as potentially the same link to the user's home page may be peppered in the pages of the host. What do you think? Thanks.

  • Intel Atom D425 Problems

    - by Nico
    I have recently bought an Intel Atom D425 mini itx board with OCZ 30 Gig SSD and 1 Gig DDR3 ram. I have installed Ubuntu 10.04 and Crunchbang Statler ok; works fine in both. I tried to install Xubuntu 12.04, Ubuntu 12.04, and Mint 13 Mate. All of those 3 start up, but as soon as you get to install it all goes wrong and the monitor says input not supported. Is it an Intel Atom D425 problem, an Ubuntu problem, or something else? All help would be much appreciated Regards Nico

  • dhcp configuration not working ubuntu 11.10

    - by Vivek Pradhan
    I am usually behind a proxy server in college so I connect to the ethernet or wifi using manual IPv4 addresses only inside college. I have been trying really hard to get the internet work at home, there is no proxy and I have set the network to use automatic dhcp. It seems like it is not able to connect to the port, It gets disconnected after some time automatically and then tries to reconnect. The same thing is happening with wifi networks also, after some time i see a pop up asking for authentication and ultimately its not able to connect. What might be the problem here. I looked up some similar questions and checked the /etc/network/interfaces file and looks like this: auto lo iface lo inet loopback I have no idea what those lines mean but there is no configuration for eth0 or wlan0. Any help is deeply appreciated. Ubuntu loses it charms due to these small glitches.

  • forbidden foldername?

    - by j0h
    I have a little webserver i run to help me at work. in an effort to neaten up the internal bits, I made a forlder named "doc" for documents. When i try to navigate to that folder i get "You don't have permission to access /doc/ on this server." so then, i looked at the permissions. drwxrwxr-x 2 J0h J0h 4096 Nov 7 22:46 doc/ drwxrwxr-x 5 J0h J0h 4096 Nov 6 12:35 ece/ drwxrwxr-x 2 J0h J0h 4096 Nov 6 12:35 exe/ permissions of "doc" looks legit. ece/ and exe both work, and have the same permissions. So then I changed the name of the folder "doc" to "docs" and it works. So evidently the folder-name doc is a black listed folder name? is that right? what is going one here?

  • Issues signing up for Windows Azure free trial and pay as you go service

    - by Robert Greiner
    I get the following error when trying to sign up for the Azure 90-day free trial: We can't authorize the payment method. Please make sure the information is correct, or use another payment method. If you continue to get this message, please contact your financial institution. I've tried three different cards, two credit and one debit. Those cards are issued from two different banks. I've also tried the cards on two separate accounts. Someone from my work also confirmed that he could not sign up for the free trial either. Has anyone else had this problem? I haven't really seen much help searching Google and the support staff doesn't seem interested in helping people sign up for free accounts.

  • What would most games benefit from having?

    - by Phil
    I think I've seen "questions" like this on stackoverflow but sorry if I'm overstepping any bounds. Inspired by my recent question and all the nice answers (Checklist for finished game?) I think every gamedev out there has something he/she thinks that almost every game should have. That knowledge is welcome here! So this is probably going to be an inspirational subjective list of some sorts and the point is that anyone reading this question will see a point or two that they've overlooked in their own development and might benefit from adding. I think a good example might be: "some sort of manual or help section. Of course it should be proportional to how advanced the game is. Some users won't need it and won't go looking for it but the other ones that do will become very frustrated if they can't remember how to do something specific that should be in the manual". A bad example might be "good gameplay". Of course every game benefits from this but the answer is not very helpful.

I'm new at linux, but i had before linux mint 13 and the ethernet didn't work 'till a friend went to network settings-options he clicked "add" somewhere and and introduced some numbers, after he looked somewhere in my mom's computer.

  • Point Light Soft Shadows

    - by notabene
    How to implement soft shadows for omni directional (point) light. We use typical shadow mapping technique. Depth is rendered to texture cube and addresing is pretty simple then. Just using vector from light to fragments world position. It works perfectly. Until you want soft shadows. In our engine we use PCSS technique for spot lights. But for point light there begins troubles. How to sample in 3D? I developed technique when orthonormal basis is created from a direction and upvector (0,1,0). And then multiply sampling vector (something like this (1.0,i/depthMapSize,j/depthMapSize) with this basis. But this (of course :)) looks pretty bad for vectors near (0,1,0) and (0,-1,0). I will appreciate any help on this.

  • Unable to connect via Mobile Broadband - But its detected - 12.10

    - by Rexford
    Previously (on ubuntu 12.04), i will just connect my 3G mobile broadband modem, and will start browsing after enabling it and going through the setup process. However, on the 12.10, I'm able to setup my connection, but it doesn't connect to the internet. All settings are okay. I've tried two different network providers in Ghana, still, i'm not able to connect. At times, i'm notified that, its connected to the "home network" of the service provider, but disconnects in less than 10 seconds. Is it supposed to be a bug? I've been reading about the wvdial, but I'm wondering something that used to be possible by "default" in Ubuntu should now be "configured" via a software. Help!
