• How should I implement a command processing application?

  - by Nini Michaels

  I want to make a simple, proof-of-concept application (REPL) that takes a number and then processes commands on that number. Example: I start with 1. Then I write "add 2", it gives me 3. Then I write "multiply 7", it gives me 21. Then I want to know if it is prime, so I write "is prime" (on the current number - 21), it gives me false. "is odd" would give me true. And so on. Now, for a simple application with few commands, even a simple switch would do for processing the commands. But if I want extensibility, how would I need to implement the functionality? Do I use the command pattern? Do I build a simple parser/interpreter for the language? What if I want more complex commands, like "multiply 5 until >200" ? What would be an easy way to extend it (add new commands) without recompiling? Edit: to clarify a few things, my end goal would not be to make something similar to WolframAlpha, but rather a list (of numbers) processor. But I want to start slowly at first (on single numbers). I'm having in mind something similar to the way one would use Haskell to process lists, but a very simple version. I'm wondering if something like the command pattern (or equivalent) would suffice, or if I have to make a new mini-language and a parser for it to achieve my goals?

• Should certain math classes be required for a Computer Science degree?

  - by sunpech

  For a Computer Science degree at many colleges and universities, certain math courses are required: Calculus, Linear Algebra, and Discrete Mathematics are few examples. However, since I've started working in the real world as a software developer, I have yet to truly use the knowledge I had at once acquired from taking those classes. My question is: Should these math classes be required to obtain a computer science degree? Or would they better served as electives? A Slashdot post: CS Profs Debate Role of Math In CS Education

• How can I evaluate a candidate's knowledge of Html/CSS during an interview?

  - by webnoob

  I am trying to determine some good interview questions to assess the ability of people coming in for a Html/CSS job, however that topic is extremely broad, and I'm not sure what sort of questions I can ask to properly evaluate someone's HTML/CSS knowledge. What sort of questions can I ask to evaluate a candidate's Html/CSS abilities during an interview? Ideally I would like to ask few questions and then give them a real life scenario to combat.

• Learning how to integrate JavaScript with other languages

  - by beacon

  After learning JavaScript syntax, what are some good resources for learning about integrating JavaScript with other languages (HTML, XML, CSS, PHP) to create real, useful applications? I'm most interested in reading articles or other people's code - not so interested in books. Basically, I'm looking to move from programming puzzle-solvers to programming complex applications and could use some advice.

  I have to build an application where the requirement is that my clients will send data from their Android device and I have to save that data to a database. I have done the part of coding that inserts data from Android emulator to my XAMPP database on localhost, now I have to implement the real thing. How can I connect the devices where my application will be installed to the XAMPP database I have created so that the data they send can be inserted into it?

• Compute directional light frustum from view furstum points and light direction

  - by Fabian

  I'm working on a friends engine project and my task is to construct a new frustum from the light direction that overlaps the view frustum and possible shadow casters. The project already has a function that creates a frustum for this but its way to big and includes way to many casters (shadows) which can't be seen in the view frustum. Now the only parameter of this function are the normalized light direction vector and a view class which lets me extract the 8 view frustum points in world space. I don't have any additional infos about the scene. I have read some of the related Questions here but non seem to fit very well to my problem as they often just point to cascaded shadow maps. Sadly i can't use DX or openGl functions directly because this engine has a dedicated math library. From what i've read so far the steps are: Transform view frustum points into light space and find min/max x and y values (or sometimes minima and maxima of all three axis) and create a AABB using the min/max vectors. But what comes after this step? How do i transform this new AABB back to world space? What i've done so far: CVector3 Points[8], MinLight = CVector3(FLT_MAX), MaxLight = CVector3(FLT_MAX); for(int i = 0; i<8;++i){ Points[i] = Points[i] * WorldToShadowMapMatrix; MinLight = Math::Min(Points[i],MinLight); MaxLight = Math::Max(Points[i],MaxLight); } AABox box(MinLight,MaxLight); I don't think this is the right way to do it. The near plain probably has to extend into the direction of the light source to include potentional shadow casters. I've read the Microsoft article about cascaded shadow maps http://msdn.microsoft.com/en-us/library/windows/desktop/ee416307%28v=vs.85%29.aspx which also includes some sample code. But they seem to use the scenes AABB to determine the near and far plane which I can't since i cant access this information from the funtion I'm working in. Could you guys please link some example code which shows the calculation of such frustum? Thanks in advance! Additional questio: is there a way to construct a WorldToFrustum matrix that represents the above transformation?

• Algorithm for approximating sihlouette image as polygon

  - by jack

  I want to be able to analyze a texture in real time and approximate a polygon to represent a silhouette. Imagine a person standing in front of a green screen and I want to approximately trace around their outline and get a 2D polygon as the result. Are there algorithms to do this and are they fast enough to work frame-to-frame in a game? (I have found algorithms to triangulate polygons, but I am having trouble knowing what to search for that describes my goal.)

• Dynamic Environment Creation

  - by Jack

  I was wondering, I'm thinking on a more small-scale, abstracted level, but how does one create a dynamic environment a la Minecraft? In specific, I'm thinking of the world as a 3 dimensional array of block objects, how is it made so that large features such as oceans are created? The language isn't important, I'm thinking on a conceptual level, but if it helps, I use C# or C++. Thanks for any help!

• How to load stacking chunks on the fly?

  - by Brettetete

  I'm currently working on an infinite world, mostly inspired by minecraft. A Chunk consists of 16x16x16 blocks. A block(cube) is 1x1x1. This runs very smoothly with a ViewRange of 12 Chunks (12x16) on my computer. Fine. When I change the Chunk height to 256 this becomes - obviously - incredible laggy. So what I basically want to do is stacking chunks. That means my world could be [8,16,8] Chunks large. The question is now how to generate chunks on the fly? At the moment I generate not existing chunks circular around my position (near to far). Since I don't stack chunks yet, this is not very complex. As important side note here: I also want to have biomes, with different min/max height. So in Biome Flatlands the highest layer with blocks would be 8 (8x16) - in Biome Mountains the highest layer with blocks would be 14 (14x16). Just as example. What I could do would be loading 1 Chunk above and below me for example. But here the problem would be, that transitions between different bioms could be larger than one chunk on y. My current chunk loading in action For the completeness here my current chunk loading "algorithm" private IEnumerator UpdateChunks(){ for (int i = 1; i < VIEW_RANGE; i += ChunkWidth) { float vr = i; for (float x = transform.position.x - vr; x < transform.position.x + vr; x += ChunkWidth) { for (float z = transform.position.z - vr; z < transform.position.z + vr; z += ChunkWidth) { _pos.Set(x, 0, z); // no y, yet _pos.x = Mathf.Floor(_pos.x/ChunkWidth)*ChunkWidth; _pos.z = Mathf.Floor(_pos.z/ChunkWidth)*ChunkWidth; Chunk chunk = Chunk.FindChunk(_pos); // If Chunk is already created, continue if (chunk != null) continue; // Create a new Chunk.. chunk = (Chunk) Instantiate(ChunkFab, _pos, Quaternion.identity); } } // Skip to next frame yield return 0; } }
