  • OpenGL Beginner question

    - by nobby
    I'm new to OpenGL programming, but I can't find a good book to read or a tutorial, I've tried reading through the superbible or whatever its name is but it's kind of complicated to me. The tutorial at http://duriansoftware.com/joe/An-intro-to-modern-OpenGL.-Chapter-2.3:-Rendering.html is pretty ok but it doesn't cover what I need mostly, which is opengl math etc (such as projection matrix, view matrix, and so on). I'm fairly OK at C(++) (3+ years experience, I don't know if you would call that "good") What i basically want to do with OpenGL is, make a simple game (prefer 2D as a start and not 3D). Please suggest a good EBook to read and learn from.

  • What is the relationship between OpenGL, GLX, DRI, and Mesa3D?

    - by user65308
    I am starting out doing some low-level 3D programming in Linux. I have a lot of experience using the higher level graphics API OpenInventor. I know it is not strictly necessary to be aware of how all these things fit together but I'm just curious. I know OpenGL is just a standard for graphics applications. Mesa3D seems to be an open source implementation of this standard. So where do GLX and DRI fit? Digging around on Wikipedia and all these websites, I've yet to find an explanation of exactly how it all goes together. Where does hardware acceleration happen? What do proprietary drivers have to do with this? Thanks!

  • More complex learning source for C# .NET [closed]

    - by Leron
    By complex I don't mean more difficult but including a larger area of possibilities cover. I've started a few years ago with PHP and the transition from learning the syntax of the language and the basic logical structures to working with databases, including JavaScript and so on was very short. And now I'm more interested in studying working with languages like Java/C#. Recently I spend a lot of time reading and writing some simple console applications, I've read almost 2K pages for C# programming and still don't know how to connect to database for example. Just for info I'm interested in web development, socket programing and live streaming, don't know if I'm exceeding myself too much writing that but despite that I want to find some books/internet sources where I can extend my current knowledge of C#/.NET, start using database queries, maybe try something more complicated webwise.

  • I'm a PeopleSoft Developer. Should I learn other languages (C# Java...)?

    - by PSDev
    I've been doing PeopleSoft development for 2 years. Recently, I want to relocate and find out there are not that many PeopleSoft development out there. 90% of the vacant positions are contract type of jobs. I'd rather get a full time permanent position. In PS, I do a lot of maintenance rather than new programming. It does get very boring. Also, I'm not sure if Oracle will one day pull off the plug for PS. What language is in most demand and also offers above average salary? Is it C#, Java, Python, Perl, ...? Thanks.

  • dos games with dosbox running slow

    - by NeuroShell
    i have AMD E-450 1.65ghz, 4gb DDR3 ram, HD6320 laptop with dual boot ubuntu 13.04 and win 8.1, my main gaming rig(desktop pc) is with win7(so i am not playing serious games on this laptop) and for university i mostly use ubuntu(unix and programming tasks), for some free time i found dosbox on ubuntu software center and tryed playing several games(blood, syndicate wars) and all of them lag like hell(although on win 8.1 they work perfectly). So any suggestion how to solve the problem? i am using drivers X.org (in software settingsadditional settings) tryed proprietary ones but all screen colors was kinda strange and i couldn't control brightness at all... same dos games was lagging too.

  • Matrix camera, movement concept

    - by NoFace
    I was talking to some guy. He said that my movement concept in game is bad. When left or right arrow is pressed I'm scrolling background what makes you feel that player is moving (player's X remains same). So... he told me something about matrix view. I should create all walls and platforms static and scroll only the camera and move player's rectangle. I did a little research in Google, but nothing found. Can you tell me anything about it? How to start? Maybe links, books and resources? My programming language is Java (2d). Thank you!

  • Is there any simple C++ code to grab video from UVC webcam and display it simultaneously?

    - by mShero
    I'm very very new to Linux and programming! I'm using ubuntu 11.10 - 64 bits with gcc 4.6.1 I've been searching online for an example C++ code that simply grabs video from a compliant UVC webcam and displays it simultaneously.. I need to compile it on gcc. In OpenCV, it's a very simple code less than 20 lines as I remember! I found this: http://v4l2spec.bytesex.org/spec/capture-example.html But it's very huge code relative to OpenCV code ?! and even when I tried to compile it using gcc.. I got many errors! I copied the code into a cpp file: cap.cpp then wrote in the terminal: gcc cap.cpp -o cap and the errors showed up... same errors with g++ I hope if someone can help me and tell me where can I find another simpler code? and how can I test it ? Thank you :)

  • What are steps in making an operating system in C ? [duplicate]

    - by ps06756
    This question already has an answer here: Compiler/OS Design - Where to start [closed] 3 answers I am trying to make an my own OS. This is for educational purpose only, so that I get to understand the internals as well as get a good idea of low level programming. I have some prior application development experience in C#/python/C++/C. I am a noob in assembly language(very less experience and knowledge). I understand that in writing an operating system,we can't go without assembly language. Currently, I have just printed a string in assembly language in the boot sector using qemu and BIOS interrupts. What I want is that, can someone specifically point out the steps that I need to follow to make my operating systems run C programs. So that, I can start writing my OS in C. Any other piece of advice to help a newbie, regarding the same is also welcome. Although, I have looked into many os development related tutorials/websites, I can't seem to find this information anywhere.

  • Scripted Motion Paths (?) (XNA)

    - by Peteyslatts
    Ok, so the title isn't the greatest because this is a lot more general. Say I want to have the player be able to hit A and have their ship model roll to the right, and shift to the right of the screen, while the camera stays centered. Would I do that through programming (ie. set waypoints for the model and keep the camera focus still) or do it through animation ( so the ship model actually rolls and moves right, and just play those frames)(I actually don't know how to do this kind of 3D animation yet, haven't looked into it. Adding it to my To Do List) This is a really vague question I know, I'll try and answer any questions. Thanks, Peter

  • Does Turing-complete implies possibility of malware? [closed]

    - by Mathematician82
    Is it possible to build an operating system that contains some Turing complete compiler (language?) but is unable to run any malware? Or is there any definition for a malware? This question popped on my mind as I was wondering why Windows has more malware than Linux. If Linux contains a C programming language and its compiler, I think it is possible to write a Linux program that works similarly than Windows viruses. But there are less malware for Linux than for Windows although there is a Wine for Linux to simulate Windows programs.

  • What methodology to use for planning/developing a Language conversion project?

    - by user 123
    I am trying to help my friend by creating a part of his on-going project. What I'm going to do is create a Java parser to break up the Java code into operators, parameters etc to build XML representation. Next I want to create a code generator to convert the parsed java code to XML conforming to the schema I've created. Finally I want to use an XML style-sheet to transform the XML into another programming language type. Basically I just wanted some advice on which methodology/model I should use for planning and developing this project. Is there some benefit to using Agile etc for instance?

  • How to handle situation of programmer stealing credit for your project [on hold]

    - by shorecc
    There is a coworker who has stolen credit for my work. I created a system that will show live statuses of printing machines throughout the plant. There was one glitch in it so the coworker made an improvement and then re-wrote the entire system (copying 90% of my code, yet he added a new piece of hardware then took over the project). Now he asks me programming questions from time to time. I don't mind teaching coworkers how to program, but since he has stolen my ideas and credit in the past I am reluctant to teach him all I know. Today he asks me for a particularly challenging algorithm for this system. His code now looks exactly like the way I would program! How would you handle the situation? How can I decline helping him without appearing to not being a team player?

  • Ruby on rails not popular in big international IT companies?

    - by maro
    I would like to ask you for advice more experienced ROR developers. I am new in programming and like to idea of ROR and I am before the decision on which programing language to specialize Java vs ROR. In the future I wish to learn for bigger international IT companies (IBM, Accenture etc.) but as I am reading their job openings, most of them are hiring Java, C++, .NET... Is the ROR used only in startups or also in bigger companies as well? What should be the reasons of their preference of Java over ROR?

  • Output the total number of String Characters [migrated]

    - by Programmerwannabe
    My Question is what method should I use if I wanted to get the total number of characters a user inputs? without using arrays, i tried using .length() but it did not return all characters say from the first and lastname, it only returned the first name. Here's an example of my code. (Please dont laugh im really new in programming :) ) System.out.print("Enter your first and last name: "); String yourName = keyboard.next(); System.out.println("Your name has a total of " + yourName.length() + " numbers"); what happened was if i enter say "Neo Matrix" it would only return 3. I appreciate any help. thank you!

  • Want to learn a new language. Not sure which to pick.

    - by Regravity
    I've been coding in Batch, VBS and AutoIt for AGES, and while its been great and I've made some pretty complex desktop applications in AutoIt, I'd like to advance to something that is more flexible / powerful. I've found that I really love programming desktop applications to solve a wide variety of problems which is what I've been doing with AutoIt. I've done a lot of research on different languages, but I'm torn between a few, namely C++, C# and Python. Can anyone suggest which language I should tackle next? And reasons why I should?

  • In-memory DB to perform intersects on set slices

    - by IanC
    I have a specific programming need where I need to efficiently store large sorted sets in memory, query them for ranges, and intersect them against other sets that are also queried for ranged. I am looking at Redis, but I can't see a range slice command. MongoDB can only use 1 index, so it has to perform row-level scans, whereas I wish to process using columns that are intersected. I'm also looking at Counchbase, but can't easily determine from the documentation if it is suited to this. I know it uses Memcached, which is AFAIK not suited to this usage. Could anyone share potential solutions for this specific problem? EDIT For example, I need to perform the following: Get the IDs of all cars where the price is between 2000 and 3000, and intersect that will all cars where the engine capacity is between 3000 and 4000.

  • writing 3d game [closed]

    - by user1432980
    I want to write a game as my final year diploma project.(I'm a 4th-year-student now so I've got a year and several months). But I don't know what to choose: either write my own game engine using DirectX9(10)(I don't like OpenGL) or use OGRE + PhysX(Don't like Unity) I'm more interested in writing my own game engine(but I wonder if I'll create engine on the same level as even Unreal 1.0 hah) but on the other side with PhysX I'll have advanced physics in my game and with OGRE I'll have good grahics. For 3d models I want to use Maya. What do you advise me to choose? As for me I've got a little DirectX experience,not bad C++ programming skills(but not expert's) and a little knowledge of Maya. My English isn't perfect either hah...

  • What should I look into to find a career path?

    - by PetrakovichJ
    I am finishing up my bachelor's degree in computer science and am feeling somewhat burnt out in the field. I enjoy solving problems, programming, and using computers to find said solutions, but I feel that I never really concentrated on anything in particular and so I don't have any specialties or a path in technology to follow. I feel like a 'generic programmer' with nothing special to offer. My question is, where can I look to find this niche? I have interest in the environment, nature, sustainability, and other similar things. Is there something in these areas in particular where specialists are needed? My question is somewhat vague but where did you "find your niche"?

  • Random List of numbers in C

    - by Ant
    I have just started a C programming course and so far have only done the basics like printf, read a little on variables etc on the course book. The teacher has tasked us with writing a program that will take a value entered by the user, this will be the number of students in the class (25 at the moment but can be variable). It will then list the number of students randomly and place them in 3 columns. The purpose is to sort students into groups of 3 randomly, then display on the screen in columns. Now my question is not for the code that defeats the object of me attempting the exercise, but how to structure it. I can see that using an array can be used to display the list, but really after some pointers on how best to approach the problem in blocks, then I can attempt to program each block.

  • Why is n given the initial value of 1 in this loop?

    - by notypist
    From Kochan's "Programming in C": Input: printf ("TABLE OF TRIANGULAR NUMBERS\n\n"); printf (" n Sum from 1 to n\n"); printf ("--- ---------------\n"); triangularNumber = 0; for(n=1; n<=10; ++n){ triangularNumber += n; ? printf (" %i", n); } Output (only partly pasted): TABLE OF TRIANGULAR NUMBERS n = 1 Sum from 1 to n = 1 n = 2 Sum from 1 to n = 2 Question: I understand the purpose of this, but here's what I can't get my head around: If within the loop we assign an initial value of "1" to "n", then we check if n<=10, and if that's true (which it should be with the initial value), we then add "1" to n. Shouldn't (and I know it shouldn't, just don't understand why) the initial value displayed in our table be n=2 ? Thanks in advance for your patience and effort!

  • Am I making the right decision to take Information technology/system as my course in college?

    - by 123rainfan
    I am a student who just ended my high school last year. I will be entering college any time between march to August. And.. I am thinking of studying Information technology/System as my course in college. The problem is, I am unsure if this is the right path for me. I don't know if this is what I really want for my future later on! Yes, I do love learning more about computers (prefer software to hardware). But what if I don't find them interesting later on when studying? I'm worried about that as I don't wanna regret later on. To add to that, my knowledge of programming and other software development is actually quite low. Can someone advise me on what should I do? Or tell me more about Information technology (what will I study later on in college and the career path)?

  • What to use to make voice chat (and some more) on a web?

    - by Tunococ
    I am trying to make available on my website a voice chat for a small group of people that allows some other means to interact such as text messaging, photo sharing, file sharing, simple drawing and silly games. In other words, something similar to older MSN Messenger, but on the web. Any ideas on what to use? To clarify, I am looking for suggestions on languages and libraries to use. I want to be able to fully customize it as much as possible because I might want to add other (somewhat interesting) functions later. Low-level programming is fine if required, but platform dependency isn't that much preferred.
