  • Need to produce an animated texture of Water where each image tiles in all directions

    - by ProfVersaggi
    I need to produce a 2D 'animated' texture of "water" for a game in which each image tiles in 'all' directions, much like those produced by the Caustics Generator, but with the power and flexibility of something the likes of Blender. The final result from Caustics Generator is 32 images that are actually animated such that when the full 32 images are played in a loop they will seamlessly loop forever. They will not only loop in time, but each image also tile in all directions. This is nice, but it comes in only one flavor so to speak. I'd like to accomplish the same thing with a Blender type tool, and I have actually gotten to the point where I generate the X number of images, but they do not tile in 'all' directions, nor are they slightly animated. I've tried Blender texture animations using offsets but with only limited success. Does anyone know of how to (or of a tool) which will animate textures such that they tile in all (4) directions? Many thanks in advance ....

  • Custom HTML Tags: Are there any specifications stating a standard way to handle them?

    - by blesh
    It seems like for years they've just been given default styling and inline display. Is there a spec somewhere that has dictated this? I've looked over the RFC's but I'm not particularly good with RFC-ese, and I didn't notice anything anywhere. For example <body> Some content <mycustomtag>something else</mycustomtag> more content. </body> I can still style it with CSS, and the browser doesn't outright vomit... so it seems like there is some sort of expected behavior. Was that dictated by a specification?

    - by Stanford Sequeira
    I am starting an eCommerce marketplace, I am new to eCommerce, but I am taking it up as a challenge. I will have multiple vendors on my site. and they will upload their products through csv.- for bulk upload however there will be certain popular products already listed in the database, they can add those to their listing(like amazon for 3rd party sellers). I have no idea how to assign product codes for every product, can you help me out? im taking about something like amazons asin number. or may be is it possible to let vendors assign their own numbers? how does that work?

  • What stack of technologies should I use for my online game?

    - by Vee Bee
    I built a TicTacToe game to learn the .Net MVC3 framework. The basic functionality works (display board, make a move, detect winning move etc.) What I'd like to do is make it a "real" application - well-architected and using the right technology at the right layer. For instance, I'm currently saving every move to the database via a service call, which feels klugey and may become a bottleneck if this was an MMO game. How do you determine a good architecture (or right set of technologies) to use in a situation like this? I'd like to learn not just what to do, but why certain decisions are better than others. I noticed a similar thread here but it just offered opinions without explaining WHY something would be better (e.g. why Node instead of MVC3, etc.)

  • Why is 'libgnomevfs' files under /usr/include/gnome-vfs-2.0?

    - by George Edison
    Most applications, including the gnomevfs headers themselves, expect the files to be under /usr/include/libgnomevfs, but Ubuntu has them under /usr/include/gnome-vfs-2.0/libgnomevfs. Why? The package I'm referring to is called libgnomevfs2. Inside /usr/include/gnome-vfs-2.0/libgnomevfs/gnome-vfs.h` we find: #include <libgnomevfs/gnome-vfs-acl.h> #include <libgnomevfs/gnome-vfs-address.h> #include <libgnomevfs/gnome-vfs-async-ops.h> #include <libgnomevfs/gnome-vfs-cancellation.h> ... Meaning that even the headers themselves expect the files to be in that location - and nothing that includes this file will work. Am I missing something, or is this a glitch?

  • Texture not drawing on cubes

    - by Christian Frantz
    I can draw the cubes fine but they are just solid black besides the occasional lighting that goes on. The basic effect is being set for each cube also. public void Draw(BasicEffect effect) { foreach (EffectPass pass in effect.CurrentTechnique.Passes) { pass.Apply(); device.SetVertexBuffer(vertexBuffer); device.Indices = indexBuffer; device.DrawIndexedPrimitives(PrimitiveType.TriangleList, 0, 0, 8, 0, 12); } } The cubes draw method. TextureEnabled is set to true in my main draw method. My texture is also loading fine. public Cube(GraphicsDevice graphicsDevice, Vector3 Position, Texture2D Texture) { device = graphicsDevice; texture = Texture; cubePosition = Position; effect = new BasicEffect(device); } The constructor seems fine too. Could this be caused by the Vector2's of my VertexPositionNormalTexture? Even if they were out of order something should still be drawn other than a black cube

  • Drawing flaming letters in 3d on OpenGL ES 2.0

    - by Chiquis
    I am a bit confused about how to achieve this. What i want is to "draw with flames". I have achieved this with textures successfully, but now my concern is about doing this with particles to achieve the flaming effect. Am I supposed to have a Path in where i should add many particle emitters along the path that will "be emitting flames"? I understand the concept for 2d, but for 3d are the particles (that are quads) always supposed to be facing the user? Edit: Something else im worried about is the performance hit that will occur by having that many particle emitters, because there can be many letters and drawings at the same time. And each of these elements will have many particle emitters.

  • Implementing lighting similar as in CubeWorld

    - by Phito
    I am currently writing a voxel engine and my goal is to achieve something looking like CubeWorld. The problem that I am encountering is about lighting. I don't have a lot of knowledge in OpenGL but I don't think lighting in a game like that should be done with glLight. But beside that I have no idea of how to implement it. Here's what I have for the moment (with glLight): Do you have any ideas/link that could give me an idea of how to achieve that? Thanks

  • Weird issue with iptables redirection

    - by skypemesm
    I am trying to redirect all incoming traffic on UDP port 5060 to port 56790, and all outgoing traffic from 5060 to the port 56789. I used these iptables rules: iptables -t nat -I PREROUTING -p udp ! -s localhost --dport 5060 -j REDIRECT --to-port 56790 iptables -t nat -I OUTPUT -p udp ! -s localhost --sport 5060 -j REDIRECT --to-port 56789 I listen on both ports using RAW SOCKETS after setting the interface to PROMISCUOUS mode using ioctl. I see packets ONLY on 56789 i.e.SENDING side, and I do not see any packets on 56790, while wireshark shows that many packets are delivered to port 5060. Why would this happen? Any ideas? Do you think it's a problem with iptables rules or something to do with raw sockets? [This is ubuntu 10.04 and iptables v1.4.4]

  • LibreOffice Spell Checker doesn't work?

    - by Michael
    I was a little surprised to discover that in LibreOffice (3.5.4.2), the spell check doesn't actually work. I was surprised since spell checkers have been around since....80's? Not a difficult thing. I am running Ubuntu 12.04, on a relatively new install. I haven't done anything to my dictionaries or language files. Under toolsoptionslanguages writing aids, I have the option selected to check as I type and to use the English dictionaries. However, I get no errors when I type spelling mistakes on purpose, and when I run the checker it just says the spell check has completed and closes the window. Is this a bug with Libre? or have I done something wrong?

  • Is it a bad practice to include all the enums in one file and use it in multiple classes?

    - by Bugster
    I'm an aspiring game developer, I work on occasional indie games, and for a while I've been doing something which seemed like a bad practice at first, but I really want to get an answer from some experienced programmers here. Let's say I have a file called enumList.h where I declare all the enums I want to use in my game: // enumList.h enum materials_t { WOOD, STONE, ETC }; enum entity_t { PLAYER, MONSTER }; enum map_t { 2D, 3D }; // and so on. // Tile.h #include "enumList.h" #include <vector> class tile { // stuff }; The main idea is that I declare all enums in the game in 1 file, and then import that file when I need to use a certain enum from it, rather than declaring it in the file where I need to use it. I do this because it makes things clean, I can access every enum in 1 place rather than having pages openned solely for accessing one enum. Is this a bad practice and can it affect performance in any way?

  • Decent FREE Web Based FTP Alternatives?

    - by Peter
    Like the subject mentions, I'm looking for a free FTP Alternative that's web based. What I need is the ability to grant people like our marketing team the ability to upload marketing images and instantly have those images show up in ourdomain.com/images/newimage.jpg. I have found plenty of excellent file sharing programs that are essentially drop box and sharepoint alternatives but have yet to find an FTP Alternative. Also ideally multiple account authentication would be great. If anyone is familiar with cPanel I'm essentially looking for their File Manager or something very similar to it (obviously stand alone and preferably free). Does anybody know if anything like this exists?

  • Inside Red Gate - Be Reasonable!

    - by simonc
    As I discussed in my previous posts, divisions and project teams within Red Gate are allowed a lot of autonomy to manage themselves. It's not just the teams though, there's an awful lot of freedom given to individual employees within the company as well. Reasonableness How Red Gate treats it's employees is embodied in the phrase 'You will be reasonable with us, and we will be reasonable with you'. As an employee, you are trusted to do your job to the best of you ability. There's no one looking over your shoulder, no one clocking you in and out each day. Everyone is working at the company because they want to, and one of the core ideas of Red Gate is that the company exists to 'let people do the best work of their lives'. Everything is geared towards that. To help you do your job, office services and the IT department are there. If you need something to help you work better (a third or fourth monitor, footrests, or a new keyboard) then ask people in Information Systems (IS) or Office Services and you will be given it, no questions asked. Everyone has administrator access to their own machines, and you can install whatever you want on it. If there's a particular bit of software you need, then ask IS and they will buy it. As an example, last year I wanted to replace my main hard drive with an SSD; I had a summer job at school working in a computer repair shop, so knew what to do. I went to IS and asked for 'an SSD, a SATA cable, and a screwdriver'. And I got it there and then, even the screwdriver. Awesome. I screwed it in myself, copied all my main drive files across, and I was good to go. Of course, if you're not happy doing that yourself, then IS will sort it all out for you, no problems. If you need something that the company doesn't have (say, a book off Amazon, or you need some specifications printing off & bound), then everyone has a expense limit of £100 that you can use without any sign-off needed from your managers. If you need a company credit card for whatever reason, then you can get it. This freedom extends to working hours and holiday; you're expected to be in the office 11am-3pm each day, but outside those times you can work whenever you want. If you need a half-day holiday on a days notice, or even the same day, then you'll get it, unless there's a good reason you're needed that day. If you need to work from home for a day or so for whatever reason, then you can. If it's reasonable, then it's allowed. Trust issues? A lot of trust, and a lot of leeway, is given to all the people in Red Gate. Everyone is expected to work hard, do their jobs to the best of their ability, and there will be a minimum of bureaucratic obstacles that stop you doing your work. What happens if you abuse this trust? Well, an example is company trip expenses. You're free to expense what you like; food, drink, transport, etc, but if you expenses are not reasonable, then you will never travel with the company again. Simple as that. Everyone knows when they're abusing the system, so simply don't do it. Along with reasonableness, another phrase used is 'Don't be an a**hole'. If you act like an a**hole, and abuse any of the trust placed in you, even if you're the best tester, salesperson, dev, or manager in the company, then you won't be a part of the company any more. From what I know about other companies, employee trust is highly variable between companies, all the way up to CCTV trained on employee's monitors. As a dev, I want to produce well-written & useful code that solves people's problems. Being able to get whatever I need - install whatever tools I need, get time off when I need to, obtain reference books within a day - all let me do my job, and so let Red Gate help other people do their own jobs through the tools we produce. Plus, I don't think I would like working for a company that doesn't allow admin access to your own machine and blocks Facebook! Cross posted from Simple Talk.

  • video/audio output via HDMI Ubuntu 12.04

    - by lostNfound
    I've been out of the Ubuntu loop for quite a while now and have a completely new laptop now. Just installed Ubuntu 12.04 64-bit and would like to output my video and my audio via HDMI to my television. the following is the lspci | grep VGA for my computer. please tell me if there is any additional information needed and preferably how to obtain it and i will be more than happy to oblige. thank you in advance for your time and assistance in this matter. 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 540M] (rev a1) Edit: every time i restart my computer, after a short moment, i get an error message stating something along the lines "sorry, jockey needed to close unexpectedly." after researching, i discovered jockey is the name of the "additional drivers," which after initial installation, ubuntu informed me of proprietary drivers available. those are no longer available, and this error continues to occur.

  • Looking for a 24 Hour project for multiple languages [closed]

    - by Daan Timmer
    Right two friends and I came up with this idea of having a 24h programming competition. Where we are going to meet at one place and program away for 24hours long. Though we need a 'project'. Something that needs to be made within 24h. Doesn't have to be a real thing, just a nice learning 'thing'. The rules that we setup for ourselves is that the project can be programmed in any language of our own choice. What I know is that one guy is a PHP enthousiastic, we've got a C#/.NET person. And I am quite easy in languages and speak quite a few (PHP/C#.net/C++STL/Python/JavaScript/Java). Anything really language specific is out of the question. Is there anyone who happens to have a great idea for this?

  • What significant advances lost on side tracks should be revived in the main stream of software?

    - by C.W.Holeman II
    In reading Alan Kay's question on Significant new inventions I was coming up with answers that were not new ideas but old ones that have been passed by in the main stream. So, what significant lost advances that happened on a side track should be revived in the main stream of software? These would be ideas that worked well in their context but a different context appeared and became dominant the context, even though it lacked the idea. It maybe that in the new dominant context one just cannot do something or it requires great effort to be exerted.

  • Where to start for writing a simple java IDE?

    - by AedonEtLIRA
    I would like to start working on my own custom IDE. The biggest reason I want to work on the IDE is to help me gain an even greater, more intimate understanding of java (and other languages I add into it.) I don't want to do anything super fancy or revolutionary, I'd be happy if I could create something as compact as the BlueJ IDE I used in high school and be content. I have a few question on the specifics of the task that I hope I can get cleared up before I start investing time in this: Is there anything I should be aware of when writing the parser? Does anyone have any pointers that I should be aware of; pitfalls, brick walls or other constraints?

  • Web-based data generator

    - by John Paul Cook
    One of my coworkers told me about Mockaroo , a web-based data generator. I needed some test data for upcoming blog posts, so I decided to give it a try. It’s pretty good. I had to use Firefox because of problems running Mockaroo on Internet Explorer 11. Using the defaults except for changing the format to SQL, it generated output that looked something like the following. Mockaroo is so good that it generates fake data that could accidentally be real, such as email addresses. Consequently, I edited...(read more)

  • Using AWS or Azure, what to do about emails?

    - by Paul
    I'm coming from a background of paying a hosting company X amount per month for a server. This server comes with IIS, WebsitePanel and Smartermail all bundled together. When I create a new domain using WebsitePanel it automatically creates my email account. All I then need to do is configure my DNS to point to the server. I've decided that it is more cost efficient to move to AWS / Azure. Has anyone come from a similar background and moved onto a cloud system? I'd be interested to know what you did regarding emails. So far, these are the suggestions I've seen: Use Google Apps for each domain Use something like Elastic Email to sent out emails Launch a new instance and host an email server on that The first option seems like quite a lot of manual configuration, the second one works good with outgoing emails but what about receiving? Option 3 would make it less cost effective. What is your experience?

  • How do you write a macro for a special character in LibreOffice?

    - by JasperKov
    Does anyone know how to write a macro for a special character? I know LibreOffice currently doesn't have a way to set a special character to a keyboard shortcut. However, I want to work around this with a macro. My plan is to create a macro for a special character then set a keyboard shortcut to that macro. Problem is I don't know the first thing about writing a macro. Any one have a template or something that works? I also know about the compose key, but I guess I am lazy and want to actually insert special characters with as few keys as possible.

  • Is HTML5 more secure to develop for than Silverlight?

    - by King Chan
    I'm learning Silverlight, and I know that if I master it, I can apply the same concepts to WPF, which means I can do either web or desktop development pretty easily. But I've read articles and followed the discussion online, and I understand HTML5 is gaining traction for being cross-platform, and a lot of people seem to be moving to HTML5. From my understanding, any HTML5 application would be built with HTML and JavaScript (or Flash). But is it secure? It seems like anyone can easily use their browser's "view source" option and grab your code. Is this something I should be worried about, or is there a way to protect against it?

  • How can I get textures on edge of walls like in Super Metroid and Aquaria?

    - by meds
    Games like Super Metroid and Aquaria present the terrain with the other facing parts having rocks and stuff while deeper behind them (i.e. underground) there's different detail or just black. I would like to do something similar using polygons. Terrain is created in my current level as a set of overlapping square boxes. I'm not sure if this rendering method will work such a system for creating terrain but if anyone has ideas I'd love to hear them. Otherwise I'd like to know how I should re-write the terrain rendering system so it actually works to draw terrain in this manner...
