  • 3d trajectory - calculate initial velocity

    - by Skoder
    Hey, I've got a 2D projectile code sample working, but would like to extend it to 3D. How would I calculate the initial velocity of the Z-axis? At the moment, I've got: initVel.X = (float)Math.Cos(45.0); initVel.Y = (float)Math.Sin(45.0); How would I convert this to work in 3D (and add the initial velocity for the Z-axis)? In my example, X is across, Y is up down and Z is going into the screen. I also normalize the vector and multiply it by the speed. Thanks

  • How to take screenshot while a menu is open [closed]

    - by Anwar
    Possible Duplicate: How to take a screenshot of a whole desktop with app menu selection? I recently wanted to take a screen shot of a nautilus menu to provide an image to the answer of a nautilus related question. (I was looking for it). But when I opened up the menu and press the prtsrc key, nothing happened. I have also tried Shift+PrtSrc Key and Alt+PrtScr key. Result was the same. My question is : Is is not possible not take a screenshot while you have a menu open?. Is it bug or not? Note: To test this, just right-click on the desktop, and press prtsrc key.

  • Working out of a vertex array for destrucible objects

    - by bobobobo
    I have diamond-shaped polygonal bullets. There are lots of them on the screen. I did not want to create a vertex array for each, so I packed them into a single vertex array and they're all drawn at once. | bullet1.xyz | bullet1.rgb | bullet2.xyz | bullet2.rgb This is great for performance.. there is struct Bullet { vector<Vector3f*> verts ; // pointers into the vertex buffer } ; This works fine, the bullets can move and do collision detection, all while having their data in one place. Except when a bullet "dies" Then you have to clear a slot, and pack all the bullets towards the beginning of the array. Is this a good approach to handling lots of low poly objects? How else would you do it?

  • Android how to get opengl 3D coordinates in ontouch event

    - by Sandy
    I created a cube in opengl and it rotates in ontouch event. To to this I created a CustomSurfaceView as follows public class CustomSurfaceView extends GLSurfaceView { @Override public boolean onTouchEvent(MotionEvent e) { float x = e.getX() float y = e.getY(); } } Here x and y are screen coordinates. How can I get 3D coordinated from this? I have already looked gluProject and NeHe. But I dont know how to implement this in my project, it shows that there is no GLdouble,GLfloat class.

  • Displaying a grid based map using C++ and sdl

    - by user15386
    I am trying to create a roguelike game using c++ and SDL. However, I am having trouble getting it to display the map, which is represented by a 2d array of a tile class. Currently, my code is this: for (int y = 0; y!=MAPHEIGHT; y++) { for (int x = 0; x!=MAPWIDTH 1; x++) { apply_surface( x * TILEWIDTH, y * TILEHEIGHT, mymap[x][y].image, screen ); } } However, running this code causes it to both dither for a while before opening the SDL window, and (usually) tell me there is an access violation. How can I display my map?

  • How do I update the IcedTea Plugin on 12.10?

    - by Brenton Horne
    Whenever I open up the page http://www.runescape.com/game.ws? in google chrome I get the notice, "IcedTea was blocked because it is out of date" and gives me the two options of updating it or running this time. I've gone to the link attached to the option of updating it and its a wikipedia page http://icedtea.classpath.org/wiki/Main_Page that wasn't helpful for me because I didn't know what to download and install. Whenever I click, 'Run this time' it works momentarily but it is prone to have the runescape interface in the browser disappear and be replaced with a black screen.

  • finding a WUXGA or matte laptop

    - by John Paul Cook
    UPDATED: HP still sells 17" WUXGA laptops - details in the new paragraph at the end. Lenovo, Dell, Sony and Sager do not sell a 1920x1200 (WUXGA) laptop. I understand that manufacturers provide what there is market demand for. I also understand that HDTV and the 1080p standard is heavily influencing both monitor and laptop screen resolutions. But I do not understand why there is so little demand for a WUXGA laptop. Nor do I understand the popularity of glossy displays. I really don't like to look...(read more)

  • Ubuntu 12.04 shut down freezes

    - by sam
    I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

  • Gnome 3 panel and menus are all gone?

    - by Hannes
    I am running Ubuntu 11.10 using gnome 3 shell. I have set my pc to automatically log into gnome shell so I do not see the login screen. Today I installed some updates and now the gnome panel is gone. When my pc logs in I ONLY see the background. There are no menus, nothing! Even the exit, minimize and maximise buttons in the top tight corner of the windows are gone. Also, alt+f2 also does not work. Any ideas how to fix this? I have a Nvidia Geforce 7900GTO with the Nvidia proprietary drivers installed. I have also used the recovery mode and removed some packages that apparently were broken. Still does not work.

  • Moonlight stopped working on tvp.pl

    - by Oliverka
    Hello, I'm watching The Bold and the beautiful on the site: http://www.tvp.pl/seriale/obyczajowe/moda-na-sukces/wideo Yesterday I wanted to view next episode, however it didn't work. I checked various episodes from other points in time and none works. The "dots" that appear when a Silverlight video is loading are present, but after them there is only black screen (of death). I'm using Ubuntu Lucid Lynx 32 bit with GNOME2 and firefox 3.6. I have all updates done. Could somebody check if any video is working for them and tell me their setup, please? I'm using Moonlight 3. Two days ago everything was fine but later this problem appeared.

  • Circle physics and collision using vectors

    - by Joe Hearty
    This is a problem I've been having, When making a set number of filled circles at random locations on a JPanel and applying a gravity (a negative change in the y), each of the circles collide.

  • Cannot boot Win7 after updating to ubuntu 11.10

    - by angryInsomniac
    I had a dual boot setup on my system, with ubuntu 11.04 and Win7. Yesterday I updated ubuntu to 11.10. Now , I cannot seem to be able to load Win7 , I do see an entry for it on the boot menu. I select that entry and then the screen goes black , with everything coming to a standstill. I tried to wait for it to respond but nothing happened. I went through the forums and tried "grub-update" but when I do that , nothing really happens. I am not sure of this , but I get no output from grub for upto 10 minutes ( can grub-update be made verbose ) How can I fix this and get back to booting both OS'es properly ?

  • How do I get unity back?

    - by Siva
    I got the latest driver software for my old ATI Radeon 4600, and it had me restart. My screen was then just a big terminal! I could log in, but when I typed 'unity' into it as a command, it said something about DISPLAY not found; set it to :0 (zero). I don't know enough about Linux to deal with this. I am using a DSL live CD to ask this. I looked at similar questions suggested, even searched. If my question's a duplicate, I apologise, but I didn't understand what I saw there. T_T

  • Grid based collision - How many cells?

    - by Fibericon
    The game I'm creating is a bullet hell game, so there can be quite a few objects on the screen at any given time. It probably maxes out at about 40 enemies and 200 or so bullets. That being said, I'm splitting up the playing field into a grid for my collision checking. Right now, it's only 8 cells. How many would be optimal? I'm worried that if I use too many, I'll be wasting CPU power. My main concern is processing power, to make the game run smoothly. RAM is not a big concern for me.

  • Ubuntu 12.10 live-usb won't boot

    - by user109175
    I own an Aleutia "Tango" low power PC. It uses a Intel Atom CPU N2800 @1.86GHz processor. I know there are Linux issues with the "Cedar Trail" graphics on this hardware but I can happily run Ubuntu 12.04 using the VESA graphics driver. I wanted to try out Ubuntu 12.10 so I created a live USB under 12.04 but I am unable to get this to boot. It gets as far as the Grub screen but after that the monitor shuts down. I have tried the F6 "nomodeset" option but that doesn't make any difference. Does anyone have any knowledge of this problem? Thanks in advance.

  • Ubuntu Stuck at boot after update

    - by raphie
    I'm doing this question because I can't edit other questions and I'm trying to set up my computer with Ubuntu but I'm a total idiot about this. I want to give Ubuntu a try, I build up a system specially for Ubuntu but when everything seems to be OK I made a suggested update and now when I restart my computer Ubuntu is stuck in the purple screen. I read other questions about this but, as I said, I'm a total idiot with this and I don't understand a bit what you guys are talking about when saying reboot with Grub, press Ctrl-F4 or whatever. My keyboard shutdown when this happens and only accepts Alt-Ctrl-Del to reboot again. Ctrl-F4 is not working for me. Pleas Help Me, cure my MS insanity Pleaseee! :) Any help I will appreciate it!

  • Confusion on HLSL Samplers. Can I Set Samplers Inside Functions?

    - by Kyle Connors
    I'm trying to create a system where I can instance a quad to the screen, however I've run into a problem. Like I said, I'm trying to instance the quad, so I'm trying to use the same geometry several times, and I'm trying to do it in one draw call. The issue is, I want some quads to use different textures, but I can't figure out how to get the data into a sampler so I can use it in the pixel shader. I figured that since we can simply pass in the 4 bytes of our IDirect3DTexture9* to set the global texture, I can do so when passing in my dynamic buffer. (Which also stores each objects world matrix and UV data) Now that I'm sending the data, I can't figure how to get it into the sampler, and I really want to assume that it's simply not possible. Is there any way I could achieve this?

  • Why did visual programming never take off and what future paradigms might change that?

    - by Rego
    As the number of "visual" OS's such as Android, iOS and the promised Windows 8 are becoming more popular, it does not seem to me that we programmers have new ways to code using these new technologies, due to a possible lack in new visual programming languages paradigms. I've seen several discussions about incompatibilities between the current coding development environment, and the new OS approaches from Windows 8, Android and other tablets OS's. I mean, today if we have a new tablet, it's almost a requirement for coding, to have, for instance, an external keyboard (due it seems to me it's very difficult to program using the touch screen), exactly because the coding assistance is not conceived to "write" thousands of lines of code. So, how advanced should be the "new" visual programming languages paradigms? Which characteristics these new paradigms would be required?
