• Audio Panning using RtAudio

  - by user1801724

  I use Rtaudio library. I would like to implement an audio program where I can control the panning (e.g. shifting the sound from the left channel to the right channel). In my specific case, I use a duplex mode (you can find an example here: duplex mode). It means that I link the microphone input to the speaker output. I seek on the web, but I did not find anything useful. Should I apply a filter on the output buffer? What kind of filter? Can anyone help me? Thanks

• How do I Fallback to Older DirectX Versions?

  - by smoth190

  I had a feeling that it would be easier to tackle this problem before I got too deep into development (unless, of course if that's a bad idea/the hard way, please inform me...). I'm creating my game to be run ideally on DirectX 11, however, I want to offer it on DirectX 10, and I'm unsure if it is worth offering it for DirectX 9 for XP users. I'm not too sure how this fallback even works, as I can't find many articles on the internet. If someone could give me an in-depth article, that would be great. I've read a little about how since DirectX11 is completely absent on XP, it is hard to even check for support. Someone mentioned having multiple applications for each version, is this a good idea? Thanks to anyone who can point me in the right direction here.

• How do I determine the draw order in an isometric view flash game?

  - by Gajet

  This is for a flash game, with isometric view. I need to know how to sort object so that there is no need for z-buffer checking when drawing. This might seem easy but there is another restriction, a scene can have 10,000+ objects so the algorithm needs to be run in less than O(n^2). All objects are rectangular boxes, and there are 3-4 objects moving in the scene. What's the best way to do this? UPDATE in each tile there is only object (I mean objects can stack on top of each other). and we access to both map of Objects and Objects have their own position.

• JMonkey Engine (JME) load Blender scene with textures?

  - by leigero

  I am having the hardest time trying to accomplish the simplest task. I have created a floor and 4 walls (not that complicated) in Blender. I added a basic material and cloud texture so they have something to look at other than gray. When I import them into JMonkey they show up as solid white objects with no shading or depth. White silhouettes. I thought this may be a lighting issue, but I have ambient light added to the scene. I can remove that light or adjust its intensity and it has no affect on the scene. I exported all Blender files into OgreXML format, then converted them to .j3o format in JMonkey. I renamed the textures to match their corresponding mesh and this didn't do anything. Does anybody know how to create a flat object and put it into JMonkey with a texture? This sounds simple and there is absolutely no information on this. This should be step 1!

• What is the benefit of triple buffering?

  - by user782220

  I read everything written in a previous question. From what I understand in double buffering the program must wait until the finished drawing is copied or swapped before starting the next drawing. In triple buffering the program has two back buffers and can immediately start drawing in the one that is not involved in such copying. But with triple buffering if you're in a situation where you can take advantage of the third buffer doesn't that suggest that you are drawing frames faster than the monitor can refresh. So then you don't actually get a higher frame rate. So what is the benefit of triple buffering then?

• What You Said: How You Monitor Your Computer

  - by Jason Fitzpatrick

  Earlier this week we asked you to share your computer monitoring tips and tricks, now we’re back to share the wealth. Read on to see how your fellow reader monitor their gear. One of the more popular monitoring tools, thanks in part to the amount of things beyond just hardware it can monitor, in the comments was Rainmeter. Lee writes: I don’t really monitor my computer constantly, only when something is hanging up and I need to see what’s causing it. That being said, I do have Rainmeter so I can quickly see how much RAM or CPU is being used. For anything more detailed, I just go into the task manager and sort by RAM or CPU.

• Is chess-like AI really inapplicable in turn-based strategy games?

  - by Joh

  Obviously, trying to apply the min-max algorithm on the complete tree of moves works only for small games (I apologize to all chess enthusiasts, by "small" I do not mean "simplistic"). For typical turn-based strategy games where the board is often wider than 100 tiles and all pieces in a side can move simultaneously, the min-max algorithm is inapplicable. I was wondering if a partial min-max algorithm which limits itself to N board configurations at each depth couldn't be good enough? Using a genetic algorithm, it might be possible to find a number of board configurations that are good wrt to the evaluation function. Hopefully, these configurations might also be good wrt to long-term goals. I would be surprised if this hasn't been thought of before and tried. Has it? How does it work?

• Learning Asynchronous programming

  - by xenoterracide

  Asynchronous non-blocking event driven programming seems to be all the rage. I have a basic conceptual understanding of what this all means. However what I'm not sure is when and where my code can benefit from being asynchronous, or how to make blocking IO, non-blocking. I'm sure that I can simply use a library to do this, but I'm more interested in more in depth concepts, and the various ways to implement it myself. Are there any comprehensive/definitive books, or other resources on this subject (like GoF for Design Patterns, or K&R for C, tldp for things like bash)? (Note: I'm not sure if this is actually functionally an identical question to my question on Learning event driven programming)

• Why do webpages take longer to loo in ubuntu 12.04 than Windows 7

  - by Emil Abraham

  For example, when I click on a Facebook picture, the picture remains pixelated for about 30 seconds, then starts to clear up. Or when I watch YouTube videos, I can't watch them on HD without running into buffer issues. Windows 7 is just much snappier. It might be an issue with the graphics card. Dualbooting Windows 7 64bit & Ubuntu 12.04 64 bit Specs: CPU: Intel® Core™ i7-2630QM CPU @ 2.00GHz × 8 RAM: 8GB DDR3 HDD: 50 GB to Ubuntu & Remaining 1.5 TB to Windows The interesting part: Graphics Card: On System Settings in Ubuntu: Intel® Sandybridge Mobile Graphics Card: What it should be: Radeon™ HD 7690M XT switchable graphics with 1024MB GDDR5 and up to 5093MB total graphics memory

• Game Code Design for Rendering

  - by kuroutadori

  I first created a game on the iPhone and I'm now porting it to Android. I wrote most of the code in C++, but when it came to porting it wasn't so easy. The Android way is to have two threads, one for rendering and one for updating. This due to some devices blocking when updating the hardware. My problem is that I am coming from the iPhone. When I transition, say from the Menu to the Game, I would stop the Animation (Rendering) and load up the next Manager (the Menu has a Manager and so has the Game). I could implement the same thing on Android, but I have noticed on game ports like Quake, don't do this - as far as I can tell. I have learnt that I cannot just dynamically add another Renderer class the the tree because I will probably get a dequeuing buffer error - which I believe to be a problem with the OpenGL ES side. So how is it done?

• Workaround the flip queue (AKA pre-rendered frames) in OpenGL?

  - by user41500

  It appears that some drivers implement a "flip queue" such that, even with vsync enabled, the first few calls to swap buffers return immediately (queuing those frames for later use). It is only after this queue is filled that buffer swaps will block to synchronize with vblank. This behavior is detrimental to my application. It creates latency. Does anyone know of a way to disable it or a workaround for dealing with it? The OpenGL Wiki on Swap Interval suggests a call to glFinish after the swap but I've had no such luck with that trick.

• Why isn't Stripes popular, even though it's an awesome web framework?

  - by Mr.Chowdary

  I'm new to Stripes. I worked on MVC frameworks like Struts 1.x and 2.x. When I started learning, its features are awesome and very lightweight; it has in-depth validations and offers easy integration with other frameworks too. There are no configurations and everything is simplified with annotations. I don't understand why Stripes is not popular compared with other Java web frameworks like Struts or JSF? I didn't find any drawbacks in Stripes. Any ideas why?

• Seven Random Thoughts on JavaOne

  - by HecklerMark

  As most people reading this blog may know, last week was JavaOne. There are a lot of summary/recap articles popping up now, and while I didn't want to just "add to pile", I did want to share a few observations. Disclaimer: I am an Oracle employee, but most of these observations are either externally verifiable or based upon a collection of opinions from Oracle and non-Oracle attendees alike. Anyway, here are a few take-aways: The Java ecosystem is alive and well, with a breadth and depth that is impossible to adequately describe in a short post...or a long post, for that matter. If there is any one area within the Java language or JVM that you would like to - or need to - know more about, it's well-represented at J1. While there are several IDEs that are used to great effect by the developer community, NetBeans is on a roll. I lost count how many sessions mentioned or used NetBeans, but it was by far the dominant IDE in use at J1. As a recent re-convert to NetBeans, I wasn't surprised others liked it so well, only how many. OpenJDK, OpenJFX, etc. Many developers were understandably concerned with the change of sponsorship/leadership when Java creator and longtime steward Sun Microsystems was acquired by Oracle. The read I got from attendees regarding Oracle's stewardship was almost universally positive, and the push for "openness" is deep and wide within the current Java environs. Few would probably have imagined it to be this good, this soon. Someone observed that "Larry (Ellison) is competitive, and he wants to be the best...so if he wants to have a community, it will be the best community on the planet." Like any company, Oracle is bound to make missteps, but leadership seems to be striking an excellent balance between embracing open efforts and innovating in competitive paid offerings. JavaFX (2.x) isn't perfect or comprehensive, but a great many people (myself included) see great potential, are developing for it, and are really excited about where it is and where it may be headed. This is another part of the Java ecosystem that has impressive depth for being so new (JavaFX 1.x aside). If you haven't kicked the tires yet, give it a try! You'll be surprised at how capable and versatile it is, and you'll probably catch yourself smiling while coding again.  :-) JavaEE is everywhere. Not exactly a newsflash, but there is a lot of buzz around EE still/again/anew. Sessions ranged from updated component specs/technologies to Websockets/HTML5, from frameworks to profiles and application servers. Programming "server-side" Java isn't confined to the server (as you no doubt realize), and if you still consider JavaEE a cumbersome beast, you clearly haven't been using the last couple of versions. Download GlassFish or the WebLogic Zip distro (or another JavaEE 6 implementation) and treat yourself. JavaOne is not inexpensive, but to paraphrase an old saying, "If you think that's expensive, you should try ignorance." :-) I suppose it's possible to attend J1 and learn nothing, but you'd have to really work at it! Attending even a single session is bound to expand your horizons and make you approach your code, your problem domain, differently...even if it's a session about something you already know quite well. The various presenters offer vastly different perspectives and challenge you to re-think your own approach(es). And finally, if you think the scheduled sessions are great - and make no mistake, most are clearly outstanding - wait until you see what you pick up from what I like to call the "hallway sessions". Between the presentations, people freely mingle in the hallways, go to lunch and dinner together, and talk. And talk. And talk. Ideas flow freely, sparking other ideas and the "crowdsourcing" of knowledge in a way that is hard to imagine outside of a conference of this magnitude. Consider this the "GO" part of a "BOGO" (Buy One, Get One) offer: you buy the ticket to the "structured" part of JavaOne and get the hallway sessions at no additional charge. They're really that good. If you weren't able to make it to JavaOne this year, you can still watch/listen to the sessions online by visiting the JavaOne course catalog and clicking the media link(s) in the right column - another demonstration of Oracle's commitment to the Java community. But make plans to be there next year to get the full benefit! You'll be glad you did. All the best,Mark P.S. - I didn't mention several other exciting developments in areas like the embedded space and the "internet of things" (M2M), robotics, optimization, and the cloud (among others), but I think you get the idea. JavaOne == brainExpansion;  Hope to see you there next year!

• How are Java ByteBuffer's limit and position variable's updated?

  - by Dummy Derp

  There are two scenarios: writing and reading Writing: Whenever I write something to the ByteBuffer by calling its put(byte[]) method the position variable is incremented as: current position + size of byte[] and limit stays at the max. If, however, I put the data in a view buffer then I will have to, manually, calculate and update the position Before I call the write(ByteBuffer) method of the channel to write something, I will have to flip() the Bytebuffer so that position points to zero and limit points to the last byte that was written to the ByteBuffer. Reading: Whenever I call the read(ByteBuffer) method of a channel to read something, the position variable stays at 0 and the limit variable of the ByteBuffer points to the last byte that was read. So, if the ByteBuffer is smaller than the file being read, the limit variable is pushed to max This means that the ByteBuffer is already flipped and I can proceed to extracting the values from the ByteBuffer. Please, correct me where I am wrong :)

• For 2D games, is there any reason NOT to use a 3D API like Direct3D or OpenGL?

  - by Eric Palakovich Carr

  I've been out of hobby Game Development for quite a while now. Back when I did it, most people used Direct Draw to create 2D games. By the time I stopped people were saying OpenGL or Direct3D with an orthogonal projection is just the way to go. I'm thinking about getting back into creating 2D games, in particular on mobile phone but maybe on the XNA platform as well. To make something using OpenGL I'd have a (hopefullly) small learning curve to acclimate myself to 3D development. Is there any reason to skip that and instead work with a 2D framework where I just have a Width x Height frame buffer I need to fill with pixels?

• Skip the first RenderTarget when writing to MRT with Opaque blending

  - by cubrman

  I am writing to three rendertargets and whant to know how to tell a GPU not to write to the first RT. When you write a shader you can simply output less data than you have RTs (like output a single float4 when writing to three RTs) and only the first RTs will be affected, but you cannot specify to output this data anywhere else but to COLOR0, then 1, etc. Is there a way to write to several RTs but skip the first target? If I output zeroes, the data in the target will become zeroes, but I need it to remain untuched in the first target and only change in the specified ones. The reason I need this is to prevent data loss when calling SetRendertarget() with DiscardContents RTs. I write to all the RTs at one point and I need to write to only the specified ones afterwards. It must be the first texture as I have a depth buffer linked to it (XNA 4.0). Thanks.

• samplerCubeShadow and texture offset

  - by Irbis

  I use sampler2DShadow when accessing a single shadow map. I create PCF in this way: result += textureProjOffset(ShadowSampler, ShadowCoord, ivec2(-1,-1)); result += textureProjOffset(ShadowSampler, ShadowCoord, ivec2(-1,1)); result += textureProjOffset(ShadowSampler, ShadowCoord, ivec2(1,1)); result += textureProjOffset(ShadowSampler, ShadowCoord, ivec2(1,-1)); result = result * 0.25; For a cube map I use samplerCubeShadow: result = texture(ShadowCubeSampler, vec4(normalize(position), depth)); How to adopt above PCF when accessing a cube map ?

• The payment argument is nonsense

  In response to my HTML5 apps argument a few people came back to how the payment thingy is missing from my idea, and how it will (apparently) be worthless because of that. I’ve been thinking about that a lot in the past few days, and I’m increasingly of the opinion that the payment argument is nonsense.Sure, everybody who does iPhone apps, or who’s glancing cursorily at the mobile market without trying to gain in-depth knowledge, currently believes that the App Store concept is going to be a huge...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• why is emacs allowing multiple instances?

  - by Chad

  Around the time I fresh installed Ubuntu 12.04, I noticed that I can start multiple instances of Emacs. I find this annoying because I will think that a buffer should be open, but I'm in the wrong Emacs window. I may have changed something in .emacs, but I really don't think I did. I also reverted all of my customizations that are stored in ~/.emacs.d/custom.el. Emacs previously would give some error about another emacs server being open when I would attempt to start an additional instance of it, but it no longer does this. Any ideas on how to restore this behavior?

  my laptop Toshiba Qosmio G30 has nVidia GeForce Go 7600 card and it suppose to support 3D . i run unity 2d now . I run 12.04 and the graphic driver is--VESA: G73 Board - toshg73m-- by UBUNTU. when i run /usr/lib/nux/unity_support_test -p then i get this list Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no the card is not blacklisted but a similar one with GT is! Do you think that there is a chance the laptop can run the unity 3d? and may be i could change the resolution of the screen to a higher one too! I tried all the nvidia drivers provided but none works (except 96 in ubuntu 12.04 ). i get a black screen or terminal screen. best wishes to all

• Preparing for interview questions involving scale

  - by Chaitanya

  I have over 6 years of software development experience. I have worked on multiple platforms, including mobile. However, I have not had a chance of working on scale-related issues. As a consequence, whenever someone asks a question involving a million inputs in an interview, I find myself out of depth. How do I prepare for such questions? Any books/resources to refer to? There are books for Java and Data Structures and Concurrency, but I don't know about any definitive ones to learn about scaling.

• Ad-Driven Apps Are Sucking Your Android Battery Dry

  - by Jason Fitzpatrick

  Ads in free Android apps might be annoying but you probably never imagined they were radically draining your battery. New research from Purdue University and Microsoft highlight just how much ad-driven apps tank your battery life. What did they find? That poorly designed ad-modules in free ad-driven applications are terrible at conserving energy. In popular applications like Angry Birds and Free Chess 70% of the energy the application consumed was used to drive the ads. They also surveyed other applications and found that ad-driven apps weren’t alone in excessive battery use–the New York Times app, for example, spent 15% of its battery consumption on tracking and background tasks. Hit up the link below to read the full whitepaper for a more in depth look at the methodology and results.
