• 2-components color model

  - by Cyan

  RGB is the natural color model for OpenGL. But a lot of other color models exist. For example, CMY(K) for printers, YUV for JPEG, the little cousins YCbCr and YCoCg, HSL & HSV from the 70's, and so on. All these models tend to share a common property : they are based on 3 components. Therefore my question is : Does it exist a 2-components color model ? I'm surprised to not find any. I was expecting something along the line of Hue+light could exist. I guess it cannot be as "complete" as a true 3-components color model, but a fine-enough approximation will be good for my usecase. The end objective is to store the 2 components into a single BC5 texture (GL_COMPRESSED_RED_GREEN_RGTC2 in OpenGL). The 3rd component requires a second fetch into a second texture, which hurts performance.

• 3d js map rendering

  - by gotha

  In the past I've done a 2D tile map using HTML, CSS and Javascript. Now I have the task of creating a 3D version using the same technologies - think of it like a space map where all planets have x/y/z positions. Currently, I have no idea to do this. Is there an existing library or something I can modify to do my job? If not, what method of rendering the map should I use? It needs to be as browser independent as possible, so I can't use webgl, flash or canvas. I'm considering plain JS & HTML or SVG (using Raphael for compatibility).

• After one has made many grid based puzzles how does one make then into a PDF ready for printing

  - by alan ross

  After one has generated many grid based puzzles like sudoku, kakuro or even plain crosswords and now one has to print them in a book. How does one make a pdf (book file) from them automatically. To explain the question better. One has the puzzle ready in computer format like ..35.6.89 for all nine rows. The dot being the empty cell. How does one convert then to a picture on a PDF page complete with box, automatically without doing them individually and then print a book from the pdf file. As can be seen there are other things also printed on the page all this is done automatically.

• How to manage enemy movement and shoot in a shmup?

  - by whatever

  I'm wondering what is the best (or at least a good) way of managing enemies in a shoot-em-up. Basically, what I'd do would be a class that manages displaying and updating positions of all the enemies. But how to create good deplacements for enemies? A list of where-to-go points? gravitating around some fixed points (with ponderation, distance evaluation etc.)? Same question for the shoot patterns? Can you please put me on a track?

• Basic modelling of radar

  - by Hawk66

  I'm currently researching how to model/simulate radar for my naval simulation. Since the emphasis is on modelling ASW or submarines in general, I need only a basic radar model - at least for the beginning. So, does anybody know a resource for such a simple model? The model should take signal strength of the sensor, the size of the target and the terrain (height/ground clutter) into account. Thanks.

• How are dependant quests generated in Guild Wars 2?

  - by Aufziehvogel

  I recently read that Guild Wars 2 uses a system where the creation of quests depends on which actions user took when they were presented another quest. An example was: There might be a quest to protect a person. If users do not take this action, the person might be kidnapped and later there is a quest to rescue this person. Is there any information on whether the creation of these quests is somehow automatic? From the article it sounded like automatically, but from the specific example you could also guess that people just created a task-set where they added conditions (Task 1 taken: OK; Task 1 not taken: Show Task 2). From what I heard about AI they might also have implemented some sort of a huge neural network to make decisions?

• How to move a rectangle properly?

  - by bodycountPP

  I recently started to learn OpenGL. Right now I finished the first chapter of the "OpenGL SuperBible". There were two examples. The first had the complete code and showed how to draw a simple triangle. The second example is supposed to show how to move a rectangle using SpecialKeys. The only code provided for this example was the SpecialKeys method. I still tried to implement it but I had two problems. In the previous example I declared and instaciated vVerts in the SetupRC() method. Now as it is also used in the SpecialKeys() method, I moved the declaration and instantiation to the top of the code. Is this proper c++ practice? I copied the part where vertex positions are recalculated from the book, but I had to pick the vertices for the rectangle on my own. So now every time I press a key for the first time the rectangle's upper left vertex is moved to (-0,5:-0.5). This ok because of GLfloat blockX = vVerts[0]; //Upper left X GLfloat blockY = vVerts[7]; // Upper left Y But I also think that this is the reason why my rectangle is shifted in the beginning. After the first time a key was pressed everything works just fine. Here is my complete code I hope you can help me on those two points. GLBatch squareBatch; GLShaderManager shaderManager; //Load up a triangle GLfloat vVerts[] = {-0.5f,0.5f,0.0f, 0.5f,0.5f,0.0f, 0.5f,-0.5f,0.0f, -0.5f,-0.5f,0.0f}; //Window has changed size, or has just been created. //We need to use the window dimensions to set the viewport and the projection matrix. void ChangeSize(int w, int h) { glViewport(0,0,w,h); } //Called to draw the scene. void RenderScene(void) { //Clear the window with the current clearing color glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT|GL_STENCIL_BUFFER_BIT); GLfloat vRed[] = {1.0f,0.0f,0.0f,1.0f}; shaderManager.UseStockShader(GLT_SHADER_IDENTITY,vRed); squareBatch.Draw(); //perform the buffer swap to display the back buffer glutSwapBuffers(); } //This function does any needed initialization on the rendering context. //This is the first opportunity to do any OpenGL related Tasks. void SetupRC() { //Blue Background glClearColor(0.0f,0.0f,1.0f,1.0f); shaderManager.InitializeStockShaders(); squareBatch.Begin(GL_QUADS,4); squareBatch.CopyVertexData3f(vVerts); squareBatch.End(); } //Respond to arrow keys by moving the camera frame of reference void SpecialKeys(int key,int x,int y) { GLfloat stepSize = 0.025f; GLfloat blockSize = 0.5f; GLfloat blockX = vVerts[0]; //Upper left X GLfloat blockY = vVerts[7]; // Upper left Y if(key == GLUT_KEY_UP) { blockY += stepSize; } if(key == GLUT_KEY_DOWN){blockY -= stepSize;} if(key == GLUT_KEY_LEFT){blockX -= stepSize;} if(key == GLUT_KEY_RIGHT){blockX += stepSize;} //Recalculate vertex positions vVerts[0] = blockX; vVerts[1] = blockY - blockSize*2; vVerts[3] = blockX + blockSize * 2; vVerts[4] = blockY - blockSize *2; vVerts[6] = blockX+blockSize*2; vVerts[7] = blockY; vVerts[9] = blockX; vVerts[10] = blockY; squareBatch.CopyVertexData3f(vVerts); glutPostRedisplay(); } //Main entry point for GLUT based programs int main(int argc, char** argv) { //Sets the working directory.

• Blender 2.6: How to Merge the Pros of Meshes and Surfaces

  - by fridojet

  there are two interesting kinds of objects: Meshes and Surfaces. Each of them offers very cool features. Object Type Specific Features Nice Features of Surfaces: (for example) They're as scalable as vector graphics (really nice!) You can build winding things real simply. Nice Features of Meshes: (for example) You can build organic things really good using the Sculpt Mode and a graphic tablet. You can use some special things like Physics. My Question There are things for which Surfaces are better and things for which Meshes are better. But how can I use both the best features of Surfaces and the best features of Meshes on one object at once? For example: How can I use Physics (like on Meshes) on lossless scalable objects (like Surfaces)? Thanks.

• Specifying force and angle in ApplyImpulse in box2d

  - by Deepak Mahalingam

  I need to apply an impulse on a object with a particular force and at a particular angle in Box2d. If I am right the syntax would be the following: body.GetBody().ApplyImpulse(new b2Vec2(direction, power),body.GetBody().GetWorldCenter()); The problem is my direction is in angles. I found a discussion where it was said that the way we can convert an angle into a vector would be as: new b2Vec2(Math.cos(angle*Math.PI/180),Math.sin(angle*Math.PI/180)); Now I am not sure how to combine these two. In other words, if I wish to apply a force of 30 units at an angle of 30 degrees at the center of the object, how should I do it?

• Getting Center and Radius of Irregural Object

  - by Moaz ELdeen

  I have drawn an asteroid object manually , and would like to get its center/radius by a specific equation. I think I can get them by calculated and hard-coded values. The code to draw the asteroid: void Asteroid::Draw() { float ratio = app::getWindowWidth()/app::getWindowHeight(); gl::pushMatrices(); gl::translate(m_Pos*ratio); gl::scale(3.5*ratio,3.5*ratio,3.5*ratio); gl::color(ci::Color(1,1,1)); gl::drawLine(Vec2f(-15,0),Vec2f(-10,-5)); gl::drawLine(Vec2f(-10,-5),Vec2f(-5,-5)); gl::drawLine(Vec2f(-5,-5),Vec2f(-5,-8)); gl::drawLine(Vec2f(-5,-8),Vec2f(5,-8)); gl::drawLine(Vec2f(5,-8),Vec2f(5,-5)); gl::drawLine(Vec2f(5,-5),Vec2f(10,-5)); gl::drawLine(Vec2f(10,-5),Vec2f(15,0)); gl::drawLine(Vec2f(15,0),Vec2f(10,5)); gl::drawLine(Vec2f(10,5),Vec2f(-10,5)); gl::drawLine(Vec2f(-10,5),Vec2f(-10,5)); gl::drawLine(Vec2f(-15,0),Vec2f(-10,5)); gl::popMatrices(); } According to the answer I have written that code to calculate the radius, is it correct or not ? cinder::Vec2f Asteroid::getCenter() { return ci::Vec2f(m_Pos.x, m_Pos.y); } double Asteroid::getRadius() { ci::Vec2f _vec = (getCenter()- Vec2f(15,5)); return _vec.length()*0.3f; }

• Having trouble's understanding NIF model file format?

  - by NoobScratcher

  I'm attempting too develop a 3rd party application to make it easy to import 3d model part's into my mod for skyrim the plan was to have a fileviewer and preview window of the nif model but since , I don't know what the NIF file format actually is or where to get the vertex data from it or the hole nine yards of parsing a text file in detail I'm at a lost what to do. I'm very good at C++ but not at this super over complicated file formats , id much prefer .obj over the nif file format specification here -- http://niftools.sourceforge.net/doc/nif/index.html If someone could help me in understanding the file format in a natural and simple way and the exact parsing needed to create the 3D Model in the frustum and a explanation on how you figured that out would be happy to know. I use cygwin , notepad++ , win32 7

• Drawing a line using openGL does not work

  - by vikasm

  I am a beginner in OpenGL and tried to write my first program to draw some points and a line. I can see that the window opens with white background but no line is drawn. I was expecting to see red colored (because glColor3f(1.0, 0.0, 0.0);) dots (pixels) and line. But nothing is seen. Here is my code. void init2D(float r, float g, float b) { glClearColor(r,g,b,0.0); glMatrixMode(GL_PROJECTION); gluOrtho2D(0.0, 200.0, 0.0, 150.0); } void display() { glClear(GL_COLOR_BUFFER_BIT); glColor3f(1.0, 0.0, 0.0); glBegin(GL_POINTS); for(int i = 0; i < 10; i++) { glVertex2i(10+5*i, 110); } glEnd(); //draw a line glBegin(GL_LINES); glVertex2i(10,10); glVertex2i(100,100); glEnd(); glFlush(); } int main(int argc, char** argv) { //Initialize Glut glutInit(&argc, argv); //setup some memory buffers for our display glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); //set the window size glutInitWindowSize(500, 500); //create the window with the title 'points and lines' glutCreateWindow("Points and Lines"); init2D(0.0, 0.0, 0.0); glutDisplayFunc(display); glutMainLoop(); } I wanted to verify that the glcontext was opening properly and used this code: int main(int argc, char **argv) { glutInit(&argc, argv); //setup some memory buffers for our display glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB); //set the window size glutInitWindowSize(500, 500); //create the window with the title 'points and lines' glutCreateWindow("Points and Lines"); char *GL_version=(char *)glGetString(GL_VERSION); puts(GL_version); char *GL_vendor=(char *)glGetString(GL_VENDOR); puts(GL_vendor); char *GL_renderer=(char *)glGetString(GL_RENDERER); puts(GL_renderer); getchar(); return 0; } And the ouput I got was: 3.1.0 - Build 8.15.10.2345 Intel Intel(R) HD Graphics Family Can someone point out what I am doing wrong ?

• In what kind of variable type is the player position stored on a MMORPG such as WoW?

  - by jokoon

  I even heard J. Carmack quickly talk about it... How a software can track a player's position so accurately, being on a such huge world, without loading between zones, and on a multiplayer scale ? How is the data formatted when it passes through the netcode ? I can understand how vertices are stored into the graphic card's memory, but when it comes to synchronize the multiplayer, I can't imagine what is best.

• Why Android for new (micro) consoles?

  - by Klaim

  There are a lot of new (micro) consoles with Android inside coming soon or already there (OUYA for example). My question is: why use Android and not another OS as base for these consoles? I assume that there are pragmatic answers to this but I can't see any clear killer feature. For example, one can assume that any stable Linux distribution would work (like Valve seem to think). Android is primarily targetted at mobile platforms which mean it is built around the idea of being interrupted which goes against a lot of what console devs needs in new hardware - but is not killing Android as a platform for gamedev either as it's just a constraint. Why not another OS? What's the Android killer features that make micro-console builder using it instead of Linux or anything else?

• matrix to transform unit cube to space defined by 8 arbitrary points

  - by aadster

  I asked a question relating to similar to this already, but I think this is a clearer objective of what Im trying to achieve.. or whether its possible at all! Im trying to find a transformation (matrix ideally) which would transform the 8 points of a 3d unit cube to 8 arbitrary points in space. The 8 target points have no known structure. e.g: My gut feeling is that a matrix is unable to provide this xform since the cube faces vertices can be concave.. but are there any other methods of transformation? Thanks!

• What is wrong with my speculair phong shading

  - by Thijser

  I'm sorry if this should be placed on stackoverflow instead however seeing as this is graphics related I was hoping you guys could help me: I'm attempting to write a phong shader and currently working on the specular. I came acros the following formula: base*pow(dot(V,R),shininess) and attempted to implement it (V is the posion of the viewer and R the reflective vector). This gave the following result and code: Vec3Df phongSpecular(const Vec3Df & vertexPos, Vec3Df & normal, const Vec3Df & lightPos, const Vec3Df & cameraPos, unsigned int index) { Vec3Df relativeLightPos=(lightPos-vertexPos); relativeLightPos.normalize(); Vec3Df relativeCameraPos= (cameraPos-vertexPos); relativeCameraPos.normalize(); int DotOfNormalAndLight = Vec3Df::dotProduct(normal,relativeLightPos); Vec3Df reflective =(relativeLightPos-(2*DotOfNormalAndLight*normal))*-1; reflective.normalize(); float phongyness= Vec3Df::dotProduct(reflective,relativeCameraPos); if (phongyness<0){ phongyness=0; } float shininess= Shininess[index]; float speculair = powf(phongyness,shininess); return Ks[index]*speculair; } I'm looking for something more like this:

• ArrayList of Entites Random Movement

  I have an arraylist of entites that I want to move randomly. No matter what I do, they won't move. Here is my female class: import java.awt.Graphics2D; import java.awt.Image; import java.awt.Rectangle; import java.util.Random; import javax.swing.ImageIcon; public class Female extends Entity { static int femaleX = 0; static int femaleY = 0; double walkSpeed = .1f; Random rand = new Random(); int random; int dir; Player player; public Female(int posX, int posY) { super(posX, posY); } public void update() { posX += femaleX; posY += femaleY; } public void draw(Graphics2D g2d) { g2d.drawImage(getFemaleImg(), posX, posY, null); if (Player.showBounds == true) { g2d.draw(getBounds()); } } public Image getFemaleImg() { ImageIcon ic = new ImageIcon("res/female.png"); return ic.getImage(); } public Rectangle getBounds() { return new Rectangle(posX, posY, getFemaleImg().getHeight(null), getFemaleImg().getWidth(null)); } public void moveFemale() { random = rand.nextInt(3); System.out.println(random); if (random == 0) { dir = 0; posX -= (int) walkSpeed; } } } And here is how I update the female class in the main class: public void actionPerformed(ActionEvent ae) { player.update(); for(int i = 0; i < females.size(); i++){ Female tempFemale = females.get(i); tempFemale.update(); } repaint(); } If I do something like this(in the female update method): public void update() { posX += femaleX; posY += femaleY; posX -= walkSpeed; } The characters move with no problem. Why is this?

• Bitmap rotation jitter around pivot

  - by Manderin87

  I am working on a asteriods clone and I have the ship graphic loaded as a 96x96 bitmap. When the player rotates the ship I rotate the bitmap by degree (float). rotation function: if(m_Matrix == null) { m_Matrix = new Matrix(); } else { m_Matrix.reset(); } m_Matrix.setRotate(degree, m_BaseImage.getWidth() / 2, m_BaseImage.getHeight() / 2); m_RotatedImage = Bitmap.createBitmap(m_BaseImage, 0, 0, m_BaseImage.getWidth(), m_BaseImage.getHeight(), m_Matrix, true); draw function: m_Paint.setAntiAlias(true); m_Paint.setFilterBitmap(true); m_Paint.setDither(true); canvas.drawBitmap(m_RotatedImage, (int) posX - m_RotatedImage.getWidth() / 2, (int) posY - m_RotatedImage.getHeight() / 2, m_Paint); When the bitmap is drawn, the bitmap jitters slightly around the pivot. Can anyone fix or tell me why the bitmap is jittering around the pivot? It needs to be smooth.

• AndEngine player, background and camera

  - by valdemar593

  I'm developing a 2D shooter using AndEngine. At the moment I'm trying to make the camera follow the player. As I've understood the common approach is to use the SmoothCamera zooming it and setting the chased entity. The problem is that the camera follows the player WITH background moving also (RepeatingSpriteBackground), so it looks like the player doesn't move at all though the actual position changes. So I don't really get how to make the camera follow the player and have the background not moving. Thanks in advance.

• Cube rotation DX10

  - by German

  Well I'm reading the Frank's Luna DirectX10 book and, while I'm trying to understand the first demo, I found something that's not very clear at least for me. In the updateScene method, when I press A, S, W or D, the angles mTheta and mPhi change, but after that, there are three lines of code that I don't understand exactly what they do: // Convert Spherical to Cartesian coordinates: mPhi measured from +y // and mTheta measured counterclockwise from -z. float x = 5.0f*sinf(mPhi)*sinf(mTheta); float z = -5.0f*sinf(mPhi)*cosf(mTheta); float y = 5.0f*cosf(mPhi); I mean, this explains that they do, it says that it converts the spherical coordinates to cartesian coordinates, but, mathematically, why? why the x value is calculated by the product of the sins of both angles? And the z by the product of the sine and cosine? and why the y just uses the cosine? After that, those values (x, y and z) are used to build the view matrix. The book doesn't explain (mathematically) why those values are calculated like that (and I didn't find anything to help me to understand it at the first Part of the book: "Mathematical prerequisites"), so it would be good if someone could explain me what exactly happen in those code lines or just give me a link that helps me to understand the math part. Thanks in advance!

• The input doesn't recognize that I release the key?

  - by joapet99

  I'm creating a window (JOptionPane), in response to a collision. However, if the player is holding a key down when the window pops up, the input doesn't trigger a key release when the key is released. I don't think you can just check it with a isRelease function in the input, since the input is kind of corrupt. Can you help me? The way I check if the key is down: if(input.isKeyDown(Input.KEY_A)&& TestLevel.isFighting == false){ if(owner.canMoveLeft){ position.x -= speed * delta; } } I am not handling the key release by myself, but if I check if the key is down it should work. But it doesn't.
