• g++, R_X86_64_32S : what is it ?

  - by Skypers

  Hello. I write a 3D engine in C++ with OpenGL. I usually work on this project on my archlinux 64 bits, but on theese holidays I do on a 32 bits system. I use subversion, and since the last svn up on my 64 bits system, I've got errors : http://pastebin.be/23730 core, wrapper and interface are compilet using the -fPIC option, I do not understand so ... Thanks :)

• Identifying the version of ATI Catalyst drivers

  - by snark

  I have bought a new video card based on the ATI Radeon HD 5670 chipset. I couldn't make it work with the latest ATI Catalyst drivers found on their website, only the drivers found on the CD delivered with the card worked. How can I know the version of Catalyst that is installed on my PC (running Windows 7 64-bits)? The ATI Catalyst Control Center returns the following information: Driver Packaging Version 8.673-091110a-092263C Provider ATI Technologies Inc. 2D Driver Version 8.01.01.973 2D Driver File Path /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000 Direct3D Version 8.14.10.0708 OpenGL Version 6.14.10.9120 Catalyst™ Control Center Version 2009.1110.2225.40230 I do not recognize anything pointing to a "marketing version". The website says the current version of Catalyst is 10.2.

• Remote Desktop or Streaming Software/Services that Supports Gaming

  - by Griffin

  I've simply been amazed by the quality and speed of Onlive, as this technology has the potential of making hardware requirements irrelevant to the average user. However, at the moment Onlive is only for remotely controlling video games, and not desktops or other devices in general. I'm in pursuit of software or services that can accomplish this as well as Onlive does. I need: viewer (client) program portability (able to run on a USB stick) DirectX, OpenGL / full-screen game compatibility on the server side.** Gaming-acceptable color/scaling quality and responsiveness. I have a very powerful desktop at home and I want to be able to access this raw power from any other computer that I stick my USB into (in the same way Onlive gives gamers use of their powerful servers) What software/services has most of the above? NOTE: please specify what features your suggestion doesn't have.

• VLC opening direct 3d output windows

  - by FrozenKing

  As you can in this above image there are two windows of vlc player, I just want to get rid of the other vlc direct3d output window. VLC version is latest i.e. 2.0.1. If I change the video output to some other also; this thing doesn't change. Only the title changes i.e. now it is direct3d output then it will change to openGL or as per the selected output video option. This happens when I play *.mov files.

• Windows 8, NVIDIA graphics recognition fails

  - by Roy Grubb

  I just installed Windows 8 Pro OEM 64-bit (clean install) and it won't properly recognize my graphics adapter. When I installed Win8, it automatically installed the BasicDisplay.sys driver dated 6/21/2006. 6.2.9200.16384 (win8_rtm.120725-1247). Hardware - Mobo:MSi G41M-P33 Combo CPU:Intel CoreDuo 6600 Graphics:NVIDIA GeForce 9400GT *OS* - Windows 8 Pro 64-bit OEM The graphics adapter worked fine in Windows XP. The PC is a generic box, bought locally and its mobo failed recently, so I replaced it with the G41M. Microsoft wouldn't let me re-activate Windows XP with a different mobo, so I installed Win8, which appears to work except as described next. Win8 only partially recognizes the graphics adapter and won't allow NVIDIA latest driver installer to see that it's an NVIDIA card. As a result, OpenGL doesn't work, and this is needed by the software I most use. Other than that the graphics look OK. When I say 'partially recognizes', I mean that via the Control Panel, I can see that the adapter is described as NVIDIA, but the driver remains stuck at Microsoft Basic Display Adapter no matter what I try, including "Update driver..." in adapter properties. Display Screen Resolution Advanced Settings Adapter shows: Adapter Type: Microsoft Basic Display Adapter Chip Type: NVIDIA DAC Type: NVIDIA Corporation Bios Information: G27 Board - p381n17 Don't know what this means ... no mention of 9400GT Total Available Graphics Memory: 256 MB Dedicated Video Memory: 0 MB In fact the adapter has 512MB on-board video memory. System Video Memory: 0 MB Shared System Memory: 256 MB And Control Panel Device Manager Display adapters just shows Microsoft Basic Display Adapter. No other graphics adapter, and no unknown device or yellow question mark. What I have tried so far: 1. Cleared CMOS and reset. Updated BIOS and all mobo drivers as follows: 1st I used Driver Reviver to see if any driver updates were required. It found some but I didn't use that to get the drivers. Then I switched to MSi's own mobo driver utility Live Update 5. This also showed the board needed to update several so I used it to fetch the new drivers. After that it showed that everything was up to date and I checked with Driver Reviver again, which also reported no drivers now needed updating. Rebooted. Went to the NVIDIA site to get the latest graphics adapter driver. Their auto-detect "Option 2: Automatically find drivers for my NVIDIA products" said "The NVIDIA Smart Scan was unable to evaluate your system hardware. Please use Option 1 to manually find drivers for your NVIDIA products." So I downloaded 310.70-desktop-win8-win7-winvista-64bit-international-whql.exe, which lists 9400 GT under supported products, but when I run it, it says: "NVIDIA Installer cannot continue This graphics driver could not find compatible graphics hardware." Connected the display to the on-board Intel graphics (G41 Intel Express), removed the NVIDIA card and rebooted, changed to internal graphics in CMOS. Again it installs the MS Basic Display Adapter, and can't properly run my s/w that needs OpenGL. It runs on other machines with Intel Express graphics (WinXP and 7) Shut down and pulled out the power cord. Held start button to discharge all capacitors. Removed and re-inserted NVIDIA adapter in PCI-E slot and made sure properly seated. Connected the monitor to the card, screwed plug to socket. Reconnected power cord. Started and checked in BIOS that Primary Graphics Adapter was set to PCI-E. Started Windows. Uninstalled MS Basic Display Adapter in Device Manager. Screen blanks briefly, reappears. No Graphics adapter entry was then visible in Device Manager. Restarted PC. MS Basic Display Adapter Visible again in Device Manager. Clicked in Device Manager View Show hidden devices. No other graphics adapter appears, no unknown devices. Rebooted. Tried Scan for Hardware changes. None detected. Tried right-click on MS Basic Display Adapter Properties Driver Update Driver... Search automatically. It replied that it had determined driver was up to date. I checked that there were no graphic driver-related entries in Programs and Features that I could delete (none). Searched for any other drivers with nvidia in their name and deleted them, just keeping the 306.97 installer exe file. Did a Windows Update. Ran GPU-Z which shows (main items): Microsoft Basic Display Adapter GPU G72 BIOS 5.72.22.76.88 Device ID 10DE - 01D5 DDR2 Bus Width 32 Bit Memory size 64MB Driver Version nvlddmkm 6.2.9200.16384 (ForceWare 0.00) / Win8 64 NVIDIA SLI Unknown in the drop-down at the foot, "Microsoft Basic Display Adapter" is the only option If I swap hard disks in that machine to one with a Ubuntu 10.4 installation (originally installed on the same PC), lspci shows "VGA compatible controller as NVIDIA Corporation Device 01d5 (rev a1) (prog-if 00 [VGA controller])" and "kernel driver in use: nvidia" I'm out of ideas for new things to try and would be really grateful of suggestions. Thanks!

• Wine not finding some files

  - by Levans

  I'm having strange issues with Wine : If I look a C:\windows\system32\drivers\ in wine explorer, the directory looks empty, while the directory ~/.wine/drive_c/windows/system32/drivers is not. Plus, having the H: drive mapped to my home directory, I can look at H:\.wine\drive_c\windows\system32\drivers and it is not empty, the files are here ! Thus it seems Wine has the rights to access these files. So why don't they appear on the C: drive ? Some of my programs need them. I'm using Gentoo Linux, and Wine is version 1.7.0 compiled with these useflags (from eix) : X alsa cups fontconfig gecko jpeg lcms ldap mono mp3 ncurses nls openal opengl perl png prelink run-exes ssl threads truetype udisks xcomposite xinerama xml -capi -custom-cflags -dos -gphoto2 -gsm -gstreamer -odbc -opencl -osmesa -oss -pulseaudio -samba -scanner -selinux -test -v4l ABI_MIPS="-n32 -n64 -o32" ABI_X86="32 64 -x32" ELIBC="glibc" EDIT: I just updated to wine 1.7.4 and nothing changed.

• Does a dedicated video card improve HTML5 websites, Skype or Flash games performance?

  - by Kiewic

  I have read that having a dedicated video card (GPU) improves performance if you use your computer to play video games. I guess to make this happen, video games or apps must be using especial libraries designed to share the workload with the GPU, maybe Direct X or OpenGL, I don't know. Am I wrong? So, can HTML5 websites, Adobe Illustrator, Flash games (Zynga games), Skype or Netflix benefit from a dedicated video card? I usually do the previous activities simultaneously. Should I consider changing from an integrated video card to a dedicated card if I want to improve performance? Thanks.

• Custom event loop and UIKit controls. What extra magic Apple's event loop does?

  - by tequilatango

  Does anyone know or have good links that explain what iPhone's event loop does under the hood? We are using a custom event loop in our OpenGL-based iPhone game framework. It calls our game rendering system, calls presentRenderbuffer and pumps events using CFRunLoopRunInMode. See the code below for details. It works well when we are not using UIKit controls (as a proof, try Facetap, our first released game). However, when using UIKit controls, everything almost works, but not quite. Specifically, scrolling of UIKit controls doesn't work properly. For example, let's consider following scenario. We show UIImagePickerController on top of our own view. UIImagePickerController covers our custom view We also pause our own rendering, but keep on using the custom event loop. As said, everything works, except scrolling. Picking photos works. Drilling down to photo albums works and transition animations are smooth. When trying to scroll photo album view, the view follows your finger. Problem: when scrolling, scrolling stops immediately after you lift your finger. Normally, it continues smoothly based on the speed of your movement, but not when we are using the custom event loop. It seems that iPhone's event loop is doing some magic related to UIKit scrolling that we haven't implemented ourselves. Now, we can get UIKit controls to work just fine and dandy together with our own system by using Apple's event loop and calling our own rendering via NSTimer callbacks. However, I'd still like to understand, what is possibly happening inside iPhone's event loop that is not implemented in our custom event loop. - (void)customEventLoop { OBJC_METHOD; float excess = 0.0f; while(isRunning) { animationInterval = 1.0f / openGLapp->ticks_per_second(); // Calculate the target time to be used in this run of loop float wait = max(0.0, animationInterval - excess); Systemtime target = Systemtime::now().after_seconds(wait); Scope("event loop"); NSAutoreleasePool* pool = [[ NSAutoreleasePool alloc] init]; // Call our own render system and present render buffer [self drawView]; // Pump system events [self handleSystemEvents:target]; [pool release]; excess = target.seconds_to_now(); } } - (void)drawView { OBJC_METHOD; // call our own custom rendering bool bind = openGLapp->app_render(); // bind the buffer to be THE renderbuffer and present its contents if (bind) { opengl::bind_renderbuffer(renderbuffer); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } } - (void) handleSystemEvents:(Systemtime)target { OBJC_METHOD; SInt32 reason = 0; double time_left = target.seconds_since_now(); if (time_left <= 0.0) { while((reason = CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, TRUE)) == kCFRunLoopRunHandledSource) {} } else { float dt = time_left; while((reason = CFRunLoopRunInMode(kCFRunLoopDefaultMode, dt, FALSE)) == kCFRunLoopRunHandledSource) { double time_left = target.seconds_since_now(); if (time_left <= 0.0) break; dt = (float) time_left; } } }

• pygame double buffering

  - by BaldDude

  I am trying to use double buffering in pygame. What I'm trying to do is display a red then green screen, and switch from one to the other. Unfortunately, all I have is a black screen. I looked through many sites, but have been unable to find a solution.

• 3D terrain map with Hexagon Grids

  - by Rob

  I'm working on a hobby project (I'm a web/backend developer by day) and I want to create a 3D Tile (terrain) engine. I'm using XNA, but I can use MonoGame, OpenGL, or straight DirectX, so the answer does not have to be XNA specific. I'm more looking for some high level advice on how to approach this problem. I know about creating height maps and such, there are thousands of references out there on the net for that, this is a bit more specific. I'm more concerned with is the approach to get a 3D hexagon tile grid out of my terrain (since the terrain, and all 3d objects, are basically triangles). The first approach I thought about is to basically draw the triangles on the screen in the following order (blue numbers) to give me the triangles for terrain (black triangles) and then make hexes out of the triangles (red hex). This approach seems complicated to me since i'm basically having to draw 4 different types of triangles. The next approach I thought of was to use the existing triangles like I did for a square grid and get my hexes from 6 triangles as follows This seems like the easier approach to me since there are only 2 types of triangles (i would have to play with the heights and widths to get a "perfect" hexagon, but the idea is the same. So I'm looking for: 1) Any suggestions on which approach I should take, and why. 2) How would I translate mouse position to a hexagon grid position (especially when moving the camera around), for example in the second image if the mouse pointer were the green circle, how would I determine to highlight that hexagon and then translating that into grid coordinates (assuming it is 0,0)? 3) Any references, articles, books, etc - to get me going in the right direction. Note: I've done hex grid's and mouse-grid coordinate conversion before in 2d. looking for some pointers on how to do the same in 3d. The result I would like to achieve is something similar to this video.

• Points on lines where the two lines are the closest together

  - by James Bedford

  Hey guys, I'm trying to find the points on two lines where the two lines are the closest. I've implemented the following method (Points and Vectors are as you'd expect, and a Line consists of a Point on the line and a non-normalized direction Vector from that point): void CDClosestPointsOnTwoLines(Line line1, Line line2, Point* closestPoints) { closestPoints[0] = line1.pointOnLine; closestPoints[1] = line2.pointOnLine; Vector d1 = line1.direction; Vector d2 = line2.direction; float a = d1.dot(d1); float b = d1.dot(d2); float e = d2.dot(d2); float d = a*e - b*b; if (d != 0) // If the two lines are not parallel. { Vector r = Vector(line1.pointOnLine) - Vector(line2.pointOnLine); float c = d1.dot(r); float f = d2.dot(r); float s = (b*f - c*e) / d; float t = (a*f - b*c) / d; closestPoints[0] = line1.positionOnLine(s); closestPoints[1] = line2.positionOnLine(t); } else { printf("Lines were parallel.\n"); } } I'm using OpenGL to draw three lines that move around the world, the third of which should be the line that most closely connects the other two lines, the two end points of which are calculated using this function. The problem is that the first point of closestPoints after this function is called will lie on line1, but the second point won't lie on line2, let alone at the closest point on line2! I've checked over the function many times but I can't see where the mistake in my implementation is. I've checked my dot product function, scalar multiplication, subtraction, positionOnLine() etc. etc. So my assumption is that the problem is within this method implementation. If it helps to find the answer, this is function supposed to be an implementation of section 5.1.8 from 'Real-Time Collision Detection' by Christer Ericson. Many thanks for any help!

• stress testing opencl/Ati GPU on 12.04

  - by lurscher

  What does people normally use to stress test their GPU on ubuntu 12.04? I tried installing Phoronix Benchmark suite ubuntu .deb but it tries to install freeglu3-dev and at the same time complains about $ phoronix-test-suite benchmark pts/opencl The following dependencies are needed and will be installed: freeglut3-dev This process may take several minutes. Reading package lists... Building dependency tree... Reading state information... freeglut3-dev is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 90 not upgraded. There are dependencies still missing from the system: - OpenGL Utility Kit / GLUT 1: Ignore missing dependencies and proceed with installation. 2: Skip installing the tests with missing dependencies. 3: Re-attempt to install the missing dependencies. 4: Quit the current Phoronix Test Suite process. Missing dependencies action: 4 so even if it is installing freeglu3, it still complains about missing GLUT. You can't win against GLUT it seems So, what does people use for this? i mean, really, because i have tried googling for an hour and it is not paying up Thanks!

• Texture switching with a entity system

  - by GameDev-er

  I'm using thinking of using an entity system in my game. So far I've been using Artemis with success. However, I have a question about texture switching. I read that switching textures too often is bad. So I load all the textures when the game loads like so: import org.newdawn.slick.opengl.TextureLoader; ... public HashMap<String, Texture> Textures; ... Then for each texture I do this: Texture tex = TextureLoader.getTexture("PNG", this.getClass().getResourceAsStream(texturePath)); Textures.put(textureName, tex); Then when drawing entities I do this: drawEntity() { glBindTexture(GL_TEXTURE_2D, Textures.get(entityTexture).getTextureID()); ... } Say I have 50 entities, using 10 different 3D models, each with their own texture. When the drawEntity system runs, it doesn't group by which entities use which texture. So I could be switching textures before drawing each entity! Is there a more efficient way to switch textures between entities? Or is glBindTexture() a good option?

• Ubuntu 11.10 is falling back to Unity 2D. How to get back to Unity 3D?

  - by marcioAlmada

  It happened some minutes ago when I plugged my secondary monitor and my graphical interface simply crashed. So I had to restart my session. Since the crash Ubuntu insists to use Unity2D fall back instead of the default one. I used to plug the secondary monitor everyday when at home and nothing bad happened before. This 2D version of the GUI is ugly and has a lot of problems. How can I go back to Unity 3D GUI? update It seems somehow I lost my opengl support (driver issues). $ glxinfo name of display: :0.0 Xlib: extension "GLX" missing on display ":0.0".

• Why do my LWJGL fonts have dots and lines around them?

  When we render fonts there are weird dots and lines around the text. I have no idea why this would happen. Here is an image of what it looks like: Our font class looks like this: package me.NJ.ComputerTycoon.Font; import me.NJ.ComputerTycoon.BaseObjects.UDim2; import org.lwjgl.opengl.Display; import org.newdawn.slick.Color; import org.newdawn.slick.TrueTypeFont; public class Font { public TrueTypeFont font; private int fontSize = 18; private String fontName = "Calibri"; private int fontStyle = java.awt.Font.BOLD; public Font(String fontName, int fontStyle, int fontSize) { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); //font. } public Font(int fontStyle, int fontSize) { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); } public Font(int fontSize) { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); } public Font() { font = new TrueTypeFont(new java.awt.Font(fontName, fontStyle, fontSize), true); } public void drawString(int x, int y, String s, Color color){ this.font.drawString(x, y, s, color); } public void drawString(int x, int y, String s){ this.font.drawString(x, y, s); } public void drawString(float x, float y, String s, Color color){ this.font.drawString(x, y, s, color); } public void drawString(float x, float y, String s){ this.font.drawString(x, y, s); } public void drawString(UDim2 udim, String s){ this.font.drawString((Display.getWidth() * udim.getX().getScale()) + udim.getX().getOffset(), (Display.getHeight() * udim.getY().getScale()) + udim.getY().getOffset(), s); } public String getFontName(){ return this.fontName; } public int getFontSize(){ return this.fontSize; } public TrueTypeFont getFont(){ return this.font; } } What could be causing this?

• Questions about XNA

  - by Maik Klein

  I've read tons of different threads about XNA, but I still have some questions. First of all: I have 2 years of experience programming and C# is my main language, so XNA would fit perfectly for me, but I have some concerns. People mentioned that C# has a performance loss compared to C++. Is this true? XNA only supports DirectX 9. I found the ANX framework which is pretty similar to XNA but it is capable of DirectX 11. Would this be a good alternative ? Because I'm worried about the performance loss of C#, I searched for a C++ framework and found SFML. It's based on C++ but can be integrated into C#. I already have some experience with UDK, but I am really interested in creating more by myself ( lighting physics etc ). I didn't start yet, what would you recommend me to use / learn ? I am going to create a first person shooter (3D) and I have plenty of time for this. My aim is realtime lighting, realtime global illumination, image-based reflections etc. I want to develop for Windows. Edit: I found something interesting: OpenTK. It supports the latest version of OpenGL which is on the same level as DX11 (if my knowledge is correct). It makes use of mono.

• How to fix no splash screen in Ubuntu after nvidia proprietary driver installation (also black borders)

  - by Fabio Trevisiol

  This is soultion how to fix no splash screen in Ubuntu after nvidia proprietary driver installation. It's no matter what Ubuntu version you use, it should work anyway. (TESTED ON 14.04) Open your terminal and type: sudo apt-get install v86d (TEST WITHOUT) Then: sudo gedit /etc/default/grub Find this line: #GRUB_GFXMODE=640x480 Add below (of course choose your resolution): GRUB_GFXMODE=1024x768x32 (TRY WITHOUT OR DIFFERENT BIT DEPTH) GRUB_GFXPAYLOAD_LINUX=1920x1080x32 (YOU CAN ALSO USE THE KEEP OPTION) Save file and type in terminal: echo FRAMEBUFFER=y | sudo tee /etc/initramfs-tools/conf.d/splash (ALLOWS TO AVOID THAT THE SPLASH SCREEN IS DISPLAYED FOR A FEW SECONDS) sudo update-initramfs -u sudo update-grub2 For all those who complain about the presence of black borders in "plymouth", try to make these changes before installing the nvidia driver or switch back from nvidia to nouveau and from nouveau to nvidia. Kernel update from the Software Updater? It happened to me; I don't know if it matters. I don't know for which of these reasons, but after a few reboots, the black borders are gone. UPDATE discovered the secret: during all these beautiful things, something strange happened. glxinfo | grep vendor server glx vendor string: SGI client glx vendor string: Mesa Project and SGI OpenGL vendor string: nouveau
