• Material usage, one per model or per object?

  - by WSkid

  Is it better (memory, time (of developer), space) to use single model that is unwrapped and uses a single material or to break a model down into appropriate bits, each with their own smaller texture/material? Or does it depend on the target platform as to what is acceptable - ie PC vs tablet? An example: Say you have a typical house with a tiled roof. Model it, make sure everything is attached, unwrap the walls/roof so in your UV template the walls and roof would be in one texture file, side-by-side in say a 512x512 file. Model the roof/walls as separate objects, unwrap them individually and have two UV templates. You could then have a 256x256 file for each one.

• Algorithm to simplify building/structural meshes

  - by morpheus

  I am looking for an algorithm to simplify the meshes of buildings or similar structures. EDIT: I had made a comment that Hoppe's algorithm tends to make meshes more and more spherical with simplification. But, I am not sure about it, so am deleting the comment. Buildings in contrast should tend to become more and more rectangular with increasing simplification. The D3DX extensions for D3D in version 9.0 (d3dx9.lib) used to have classes to do progressive mesh simplification. See: http://doc.51windows.net/Directx9_SDK/?url=/directx9_sdk/graphics/reference/d3dx/functions/mesh/d3dxgeneratepmesh.htm http://msdn.microsoft.com/en-us/library/windows/desktop/bb281243(v=vs.85).aspx

• Good resources for learning about graphics hardware

  - by Ken

  I'm looking for some good learning resources for graphics hardware (and associated low level software). Basically I want to learn more about what goes on underneath the opengl/direcx API layers in terms of how things are implemented. I familiar with what happens in principle during the various stages of the rendering pipeline (viewing, projection, clipping, rasterization etc). My goal is to be able to make better and more informed decisions about tradeoffs and potential optimisations when graphics/shader programming with respect to the following kinds of issues; batching view culling occlusions draw order avoiding state changes triangles vs pointsprites texture sampling etc Basically whatever the graphics programmer needs to know about modern graphics hardware in order to become more effective. I'm not really looking for specific optimisation techniques, rather I need more general knowledge so that I will naturally write more efficient code.

• What is a *slightly* less extreme equivalent to being "fluent" in a language?

  - by Mehrdad

  tl;dr: What is a less extreme (but still noticeable) alternative to the word "fluent", when saying e.g. "I am fluent in C++/Python/whatever?" I think I can call myself "fluent" in C#, because I know the language and runtime very well, and I'm very familiar with the .NET framework's APIs and classes, etc. I would like to claim the same thing for Python and C++. But while I can program in Python (I did so for an entire summer, making a website with Django), for example, I would not call myself fluent because my code isn't always "Pythonic" (e.g. using map/filter vs. list comprehensions), and I'm not too intimate with some aspects of the language and standard library yet (e.g. the introspection API, etc.). Is there a word or phrase I can use on e.g. a resume to describe what I know? I can think of "very familiar with", but is there a better word/phrase I can use?

• How many CISC instructions do compilers use?

  - by Euphoric

  CISC processors have sometimes huge instruction sets. This makes assembly programming somehow easier. But it reduces overall effectivness of the whole chip. But how many of those instructions are used by modern compilers? I'm especialy interested in relation of CISC vs. RISC where in CISC, compiler can use specialised instructions, that might increase effectivness. But do compilers use those instructions? If yes, then how many of them are used?

• MSM Merge Modules in Visual Studio 2013 [on hold]

  - by theGreenCabbage

  Could someone please let me know where I might find resources for creating MSM files? While I am able to create MSI files using InstallShield, it seems that Visual Studio no longer supports Merge Module Projects, judging by the link below and the screenshot of my version of Visual Studio 2013 - http://msdn.microsoft.com/en-us/library/z6z02ts5(v=vs.80).aspx To create a new merge module project: On the File menu, point to Add, then click New Project. In the resulting Add New Project dialog box, in the Project types pane, open the Other Project Types node and select Setup and Deployment Projects. In the Templates pane, choose Merge Module Project.

• XNA When to call LoadContent

  - by Peteyslatts

  I have an enum in my game that denotes the game state ie MainMenu, InGame, GameOver, Exit and I was wondering if it would be advisable to add a new one in for PrepGame - in which the game creates viewports for however many players there are, creates the battlefield etc. I feel like this is a good idea except for one thing: should I make a call back to LoadContent() in this state? I could just put a switch statement in the LoadContent for my currentGameState. If it equals PrepGame load things like the skybox, ship models, texures, HUD graphics etc. Or is it a good idea to create an Asset Manager class in the first call to LoadContent() and load everything then. I feel like both approaches have different benefits: faster, but more load times vs slower initial load time, but then all my objects are referencing the same variables so I only have to load each on once. Any help is greatly appreciated. Thanks, Peter

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• Where can I train my game AI skills? (any upgoing competition?) [on hold]

  - by user1671710

  There are 2 main options - building AI plugin for existing game or entering to some competition. Do you have some concrete tips? Is there any competition which will be soon open? From my research, competitions: http://aichallenge.org (last 2011) http://www.battlecode.org (January 2014) http://webdocs.cs.ualberta.ca/~cdavid/starcraftaicomp/index.shtml (August 2014) http://aibirds.org (maybe summer 2014) http://www.marioai.org (last 2012) http://www.ice.ci.ritsumei.ac.jp/~ftgaic/index.htm (last 2013) http://www.pacman-vs-ghosts.net (last 2012) http://ai-contest2013.gameloft.com/index/contest (last 2013) http://www.botprize.org/ (last 2012) And maybe more. These are from quick research. Obviously there were many competitions this year but it is difficult to catch it. Main question is: Do you have any information of any currently running AI competition?

• Why use C++ when C works for large projects equally well?

  - by Karl

  Before I start, please DO NOT make this into a C vs C++ flamewar. This question has nothing to do with which language is better or not. Period. I have read that C++ is said to be fit for large projects. After all, it makes managing code easier. OO and other features, for example the STL. But then why use C++ when C works equally well for large projects? Take the example of the Linux kernel. Or GNOME. Or even Windows I guess, it is written in C right? So why bother at all with the complexity of C++ (templates and all that), when C works well and this is not just a statement, but proper examples have been quoted. If it works for projects of magnitude of the kernel, why is C++ preferred or why is C not used for almost all projects?

• Should I leave href empty when implementing click events via jQuery?

  - by dreza

  Is it preferable to have # in a link's href attribute when I am implementing the click event via jQuery, or is it ok to leave href empty? i.e. <a id="myLink" href="#" /> vs <a id="myLink" href="" /> When I'm doing $("#myLink").on('click', function() { // do ajaxy stuff }); Although I understand the click event could be on a span or other such element I'm interested in this case for particular best practices when using an a tag.

• XNA 4 game for both profiles

  - by Vodácek

  I am writing game in XNA 4 and this version have two profiles hi-def and reach. My problem is that I need to have my game code for each of these profiles and is very uncomfortable to have two projects and do all changes in both of them. My idea was to use preprocessor directive (i am not sure about name of this, http://msdn.microsoft.com/en-us/library/ed8yd1ha%28v=vs.71%29.aspx) and use IF statement at places with problems with profile. There is only problem that program needs to be compiled two times (for each profile) and manually changed directive and project settings to another profile. And my questions are: Is that good way? Is there better and cleaner way how to do this?

• Visual Studio Setup - why is solution explorer on the right?

  - by amelvin

  Every time I install VS (whichever version going back years) it installs with the Solution Explorer on the right. Now as most UIs have the navigation in a left hand column (and at the top of the viewport) and the content to the right of this navigation this always seems wrong to me. So I drag the solution explorer to the left of the screen and dock it there. But I've never seen another developer do this. Considering how most programmers usually like to customize their environment, adding their favourite text editor, browser, plug-ins, greasemonkey scripts etc why do Visual Studio developers never seem to make this simple UI change? Does anyone else do this or am I just screaming in the dark?

• Not assigning Bugs to a specific user

  - by user2977817

  My question: Is there a benefit to NOT assigning a Bug to a particular developer? Leaving it to the team as-a-whole? Our department has decided to be more Agile by not assigning Bugs/Defects to individuals. Using Team Foundation Server 2012, we'll place all Bugs in a development team's "Area" but leave the "Assigned To" field blank. The idea is that the team will create a Task work item which will be assigned to an individual and the Task will link to the Bug. The Team as a whole will therefore take responsibility for the Bug, not an individual, aligning to Scrum - apparently. I see the down side. The reporting tools built into TFS become less useful when you cannot sort by assigned vs unassigned, let alone sorting by which user Bugs are assigned. Is there a benefit I'm not seeing? Besides encouraging teamwork by putting the responsibility on the team-as-a-whole instead of an individual?

• iOS: game with facebook challenges

  - by nazz_areno

  I created a game for iPad and I want to challenge my facebook friends. I follow the iOS tutorial in "facebook dev docs", with the "Smash game", but it doesn't explain how to challenge a friend directly to a game. I will explain with an example: I want to start a new match and I want challenge a friend on facebook. Then I send him a request to install the app and when I detect that its app is installed I send him a request to play vs me. Then, when I finish the match I sent him my result and my friend do the same thing. But if I and my friend don't finish the match it is not possible to send another challenge. This scenario is not explained by facebook sdk. Is it necessary to use another instrument to do this situation?

• Initialize array in amortized constant time -- what is this trick called?

  - by user946850

  There is this data structure that trades performance of array access against the need to iterate over it when clearing it. You keep a generation counter with each entry, and also a global generation counter. The "clear" operation increases the generation counter. On each access, you compare local vs. global generation counters; if they differ, the value is treated as "clean". This has come up in this answer on Stack Overflow recently, but I don't remember if this trick has an official name. Does it? One use case is Dijkstra's algorithm if only a tiny subset of the nodes has to be relaxed, and if this has to be done repeatedly.

• Do you use ReSharper full time, or only enable it when needed?

  - by gorohoroh

  Based on a multitude of questions related to temporarily disabling ReSharper, and also on certain research data, I can see that a considerable share of ReSharper users have it disabled most of the time. They tend to enable it for a limited period of time (say, several hours), do whatever they need to do using its functionality, and disable it back until the next time they feel they need to use it. If you're using ReSharper (or other similar VS extensions, to that matter) in such occasional manner, can you clarify why you're doing this? Is your behavior based on performance, or other considerations? What kinds of tasks do you enable ReSharper for in this scenario?

• Why do Git users say that Subversion does not have all the source code locally?

  - by johnny

  I'm only going on what I've read on SO, so forgive me, but all I read says that one major advantage of Git over Subversion is that Git gives all the source code to the developer locally, not having to do anything on the server. With my limited using of SVN and TortoiseSVN, I had all the source code, or at least I thought I did. For example, I have a website. I upload it to SVN. I am still running my website locally, aren't I? If someone submits a change and I'm not connected, it wouldn't matter if I had Git or not, until I reconnect to the server. I do not understand. I'm not asking for a rehash of one vs. the other except this one point.

• How could your company's learning/development department best serve you?

  - by MTR

  I'll preface my question with a disclaimer - I am not an engineer, I'm just someone who works with them full-time, in a learning and development capacity. Given that, one of the comments I get regularly from the engineers I'm tasked with developing is that they feel that they're having solutions (both technical and non-technical) for development "pushed" at them vs. anyone from my field consulting with them to determine what they really need. So my question is - if you could give your company a list of the top 3-5 things they could do - in a classroom, or elsewhere - to develop meaningful skills that would help you be a better engineer, a better employee, and one more likely to STAY with the company for the long haul, what would make the cut and why? Thanks in advance for your responses.

• Distributing a very simple application

  - by vanna

  I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually distributing the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt on my git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this distribution process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to distribute it in a professionnal way ?

• Which Git-based MIS to track workflow like Trac/Redmine but on console minimastically?

  - by hhh

  Definitions MIS = management information system Some list about console based solutions here and some GUI-hacks here. Been fed up to install all those dependencies and no make -files with GUI -things so which console-based MIS would you suggest for a game-development team with graphical -repo, animation -repo, code -repo, stories -repo, etc ? P.s. I do use Git -submodules and the reason for repo -fragmentation is due to roles and size, certain repos such as graphic -repos tend to be quite large so better to keep them separate. Perhaps useful to readers interested about this http://stackoverflow.com/questions/5881578/trac-vs-redmine https://github.com/jchris/sofa

• how much is a graduate Information Technology (IT) degree worth?

  - by T. Webster

  I have a bachelor's degree in IS/MIS not CS, and a few years of software development experience now. I want to pursue some sort of graduate education that will give me more career options. I was wondering if it's worth pursuing a graduate degree in Information Technology (not CS). -How much is a master's degree in Information Technology worth? By this I mean how marketable does it make you, and how valuable is the education itself. -How does its worth compare to a master's in CS? -What types of employers are looking for the IT master's degree vs. a Computer Science master's degree? -What's the most valuable thing an Information Technology degree can give, that someone wouldn't have without the degree? Thanks.
