• Blender: How to "meshify" an object I made from Bezier curves

  - by capcom

  I made a star shape using Bezier curves, and extruded it (see pic below): What I want to do is give it a rounder look - not just around the edges by using beveling. I want it to kind of look like this (well, that shape anyway): How would I go about doing this? Please keep in mind that I am extremely new to Blender. I thought that I could somehow turn this star into those default shapes that have tonnes of squares which I could pull out, and apply a mirror to it so that the same thing happens on both sides. I really don't know how to do it, and would appreciate your help.

• Architecture: Bringing Value to the Table

  - by Bob Rhubart

  A recent TechTarget article features an interview with Business Architecture expert William Ulrich (Take a business-driven approach to application modernization ). In that article Ulrich offers this advice: "Moving from one technical architecture might be perfectly viable on a project by project basis, but when you're looking at the big picture and you want to really understand how to drive business value so that the business is pushing money into IT instead of IT pulling money back, you have to understand the business architecture. When we do that we're going to really be able to start bringing value to the table." In many respects that big picture view is what software architecture is all about. As an architect, your technical skills must be top-notch. But if you don't apply that technical knowledge within the larger context of moving the business forward, what are you accomplishing? If you're interested in more insight from William Ulrich, you can listen to the ArchBeat Podcast interview he did last year, in which he and co-author Neal McWhorter talked about their book, Business Architecture: The Art and Practice of Business Transformation.

• Fixed timestep and interpolation question

  - by Eric

  I'm following Glenn Fiedlers excellent Fix Your Timestep! tutorial to step my 2D game. The problem I'm facing is in the interpolation phase in the end. My game has a Tween-function which lets me tween properties of my game entites. Properties such as scale, shear, position, color, rotation etc. Im curious of how I'd interpolate these values, since there's a lot of them. My first thought is to keep a previous value of every property (colorPrev, scalePrev etc.), and interpolate between those. Is this the correct method? To interpolate my characters I use their velocity; renderPostion = position + (velocity * interpolation), but I cannot apply that to color for example. So what is the desired method to interpolate various properties or a entity? Is there any rule of thumb to use?

• Retrieving model position after applying modeltransforms in XNA

  - by Glen Dekker

  For this method that the goingBeyond XNA tutorial provides, it would be really convenient if I could retrieve the new position of the model after I apply all the transforms to the mesh. I have edited the method a little for what I need. Does anyone know a way I can do this? public void DrawModel( Camera camera ) { Matrix scaleY = Matrix.CreateScale(new Vector3(1, 2, 1)); Matrix temp = Matrix.CreateScale(100f) * scaleY * rotationMatrix * translationMatrix * Matrix.CreateRotationY(MathHelper.Pi / 6) * translationMatrix2; Matrix[] modelTransforms = new Matrix[model.Bones.Count]; model.CopyAbsoluteBoneTransformsTo(modelTransforms); if (camera.getDistanceFromPlayer(position+position1) > 3000) return; foreach (ModelMesh mesh in model.Meshes) { foreach (BasicEffect effect in mesh.Effects) { effect.EnableDefaultLighting(); effect.World = modelTransforms[mesh.ParentBone.Index] * temp * worldMatrix; effect.View = camera.viewMatrix; effect.Projection = camera.projectionMatrix; } mesh.Draw(); } }

• Inconsistent mouse cursor status while typing

  - by Jim

  I have noticed that when I type in some programs, Text Editor, Terminal, Bluefish, Gnome Baker, etc. the mouse cursor disappears while I am typing. In other programs like Firefox and LibreOffice, it does not. I am not an application programmer, but I imagined it has to do with their cross-platform nature and the way they are compiled or the toolkits they use. Then I noticed that Gnome-Do behaves the same way, the cursor stays on screen while typing. Why is there inconsistent handling of the mouse cursor, while typing, across different applications? Thank you.

• 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?

• gnome-control-center can't set display resolution under openbox

  - by Andy

  I'm running Ubuntu 11.10 with Openbox on my laptop. Since I need to plug different external displays into it and Openbox environment doesn't automatically pick them up, I thought the best solution I can come up with is to use gnome-control-center and it's display settings tool from within Openbox. But although this tool does detect monitors correctly, it can't do any change -- clicking Apply button just doesn't seem to do anything. So my questions are: 1) how to get this tool working? 2) how to run "Displays" tool directly from command-line, skipping control center? 3) is there a better way to automatically detect and set resolutions on internal/external monitors under Openbox? Please note I tried arandr too and it doesn't even work for my environment (doesn't detect external display plugging in at all). For what it's worth, my laptop is Lenovo G560, Ubuntu is x64 version with all the updates rolled over. Thanks for your consideration.

• XNA Transparency depending on drawing order?

  - by DarthRoman

  I am drawing two 3D objects, both of them can fade from opaque to transparent independently, and they can intersect between them (so you cannot say when one of them is before the other one). Look at the image for a better understanding (one of the object is a terrain and the other one an area): Now, if I apply transparency to both of them, and draw the terrain before the area, the terrain is not transparent respecting to the area, but the area is: And finally, if I draw the area before the terrain, then the area is not transparent respecting of the terrain: QUESTION: How can I make all the objects transparent to the rest of objects without depending on the drawing order?

• What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

  - by aristos

  Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?

• Software license restricting commercial usage like CC BY-NC-SA

  - by Nick

  I want to distribute my software under license like Creative Commons Attribution - Non commercial - Share Alike license, i.e. Redistribution of source code and binaries is freely. Modified version of program have to be distributed under the same license. Attribution to original project should be supplied to. Restrict any kind of commercial usage. However CC does not recommend to use their licenses for software. Is there this kind of software license I could apply? Better if public license, but as far as I know US laws says that only EULA could restrict usage of received copy?

• Thread problem updating Windows Forms control in XNA C#

  - by Luis

  I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

• What are the appropriate mount options for a shared NTFS partition on an SSD in a dual boot Ubuntu/Windows setup?

  - by Andreas Jonsson

  I have Ubuntu 13.10 and Windows 7 installed in dual boot on a single SSD. In addition they share an NTFS partition where I put all my data and documents. What is the optimal way to mount this NTFS partition in /etc/fstab (considering performance and minimizing wear of the SSD)? Similar questions have been asked, but I could not find answers to this particular scenario. As I understand it, the mount option 'discard' is not supported for NTFS and so should not be used (although it is recommended here). Another often quoted mount option is 'noatime'. I use it for my ext4 partitions. Does it apply to NTFS? My current /etc/fstab line is: UUID=XXXXXXXXXXXXXXXX /dos ntfs defaults,nls=utf8,uid=1000,gid=1000 0 0

• College for Game Development [closed]

  - by Cole Adams

  I am currently a Freshman Computer Science Major at Samford University, but I am realizing that the actual field I want to get into is Game Development. I go to all of these classes that are supposed to make you well rounded that have nothing to do with what I want to do and frankly, after 18 years of schooling, I am sick of having to be in classes like that. I want to go to a Game Design/Development school where that is the priority and I am not overburdened with useless classes. At this point I am so tired of the Samford classes already that I am heavily considering taking next semester off and just getting a job and focusing on learning programming on my own or something like that. My question is what would be some good schools to apply to for enrollment in 2013 and what does it take to get into these schools? Thanks in advanced.

• Inspirational software for end-users written in Haskell?

  - by Lenny222

  I think great technology ist invisible. Besides the usual suspects (GHC, Xmonad, proprietary trading software) what great examples are there for end-user software written in Haskell? I think good examples are FreeArc, Hledger and "Nikki And The Robots". Do you have more examples (full blown GUI apps, small CLI tools, etc)? Edit: For example i am fascinated by Wings3D, because while written in Erlang, users can not tell that. It just works. Among Haskell's weak spots are cross-platform GUIs. There are not many GUI apps written in Haskkel in general and most of them are no easy to use, install or even compile. What are good examples to learn from how to make hard things look easy?

• Differences between C# and Javascript for Unity [closed]

  - by vrinek

  Apart from the language differences (class-based vs prototypical, strong vs weak typing), what are the differences between using Javascript and using C# when developing games in Unity3D? Is there a noticable performance difference? Is the javascript code packaged as-is? And if yes, does this help the game's modability? Is it possible to use libraries developed for one language while developing in the other one? Is it possible to mix the two languages in the same Unity project by coding some parts in C# and others in Javascript? The next couple of questions are time-specific so feel free to ignore or remove: If libraries are not cross-functional, which language has better library support from the game development perspective? Which language has better game dev specific resources available (books, websites, forums)?

• Is Haskell's type system an obstacle to understanding functional programming?

  - by Eric Wilson

  I'm studying Haskell for the purpose of understanding functional programming, with the expectation that I'll apply the insight that I gain in other languages (Groovy, Python, JavaScript mainly.) I choose Haskell because I had the impression that it is very purely functional, and wouldn't allow for any reliance on state. I did not choose to learn Haskell because I was interested in navigating an extremely rigid type system. My question is this: Is a strong type system a necessary by-product of an extremely pure functional language, or is this an unrelated design choice particular to Haskell? If it is the latter, I'm curious what would be the most purely functional language that is dynamically typed. I'm not particularly opposed to strong typing, it has its place, but I'm having a hard time seeing how it benefits me in this educational endeavor.

• OpenGL programming vs Blender Software, which is better for custom video creation?

  - by iammilind

  I am learning OpenGL API bit by bit and also develop my own C++ framework library for effectively using them. Recently came across Blender software which is used for graphics creation and is in turn written in OpenGL itself. For my part time hobby of graphics learning, I want to just create small-small movie or video segments; e.g. related to construction engineering, epic stories and so on. There may be very minimal to nil mouse-keyboard interaction for those videos, unlike video games which are highly interactive. I was wondering if learning OpenGL from scratch is worth for it or should I invest my time in learning Blender software? There are quite a few good movie examples are created using Blender and are shown in its website. Other such opensource cross platform alternatives are also welcome, which can serve my aforementioned purpose.

• Calculate gears rotation for a realtime simulation

  - by nkint

  Hi I'm trying to do a game with real time simulations of gears. There is a big Gear with inside a smaller gear. I managed to draw gears with different diameters but equal size teeth, but if i try to move the smaller one inside the bigger one the movement is odd. see the animated gif. the biggest gear is in center C1 and the small in the center C2. I calculate C2 position in this way: C2.x = C1.x + C1_RADIUS-C2_RADIUS) * cos(t); C2.y = C1.y - C1_RADIUS-C2_RADIUS) * sin(t); for t that goes from 0 to TWO_PI in n steps. I apply as rotation the angle t, but maybe it is wrong and i have to calculate another rotation for get a perfect joint

• Sitemaps showing twice in Webmaster Tools

  - by Andrew Lott

  Within my Webmaster Tools account I'm able to able to view details about Sitemaps that are uploaded for websites I manage. For some reason each sitemap is listed twice with the exact same details under both "By me" and "All". Even sites that don't have a sitemap yet tell me I have 0 sitemaps, twice... I originally thought this might apply to sites that have multiple "Users & Site Owners" in Webmaster Tools, but it even happens for sites that only I manage. I've checked other user accounts to compare and this doesn't happen; they just get one set of tabs for By Me/All, not two. What could be causing this?
