  • Lua and C++: separation of duties

    - by topright
    Please hel to classify ways of organizing C++/Lua game code and to separate their duties. What are the most convenient ways, which one do you use? For example, Lua can be used for initializing C++ objects only or at every game loop iteration. It can be used for game logic only or for graphics, too. Thank you.

  • What (tf) are the secrets behind PDF memory allocation (CGPDFDocumentRef)

    - by Kai
    For a PDF reader I want to prepare a document by taking 'screenshots' of each page and save them to disc. First approach is CGPDFDocumentRef document = CGPDFDocumentCreateWithURL((CFURLRef) someURL); for (int i = 1; i<=pageCount; i++) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init]; CGPDFPageRef page = CGPDFDocumentGetPage(document, i); ...//getting + manipulating graphics context etc. ... CGContextDrawPDFPage(context, page); ... UIImage *resultingImage = UIGraphicsGetImageFromCurrentImageContext(); ...//saving the image to disc [pool drain]; } CGPDFDocumentRelease(document); This results in a lot of memory which seems not to be released after the first run of the loop (preparing the 1st document), but no more unreleased memory in additional runs: MEMORY BEFORE: 6 MB MEMORY DURING 1ST DOC: 40 MB MEMORY AFTER 1ST DOC: 25 MB MEMORY DURING 2ND DOC: 40 MB MEMORY AFTER 2ND DOC: 25 MB .... Changing the code to for (int i = 1; i<=pageCount; i++) { CGPDFDocumentRef document = CGPDFDocumentCreateWithURL((CFURLRef) someURL); NSAutoreleasePool *pool = [[NSAutoreleasePool alloc]init]; CGPDFPageRef page = CGPDFDocumentGetPage(document, i); ...//getting + manipulating graphics context etc. ... CGContextDrawPDFPage(context, page); ... UIImage *resultingImage = UIGraphicsGetImageFromCurrentImageContext(); ...//saving the image to disc CGPDFDocumentRelease(document); [pool drain]; } changes the memory usage to MEMORY BEFORE: 6 MB MEMORY DURING 1ST DOC: 9 MB MEMORY AFTER 1ST DOC: 7 MB MEMORY DURING 2ND DOC: 9 MB MEMORY AFTER 2ND DOC: 7 MB .... but is obviously a step backwards in performance. When I start reading a PDF (later in time, different thread) in the first case no more memory is allocated (staying at 25 MB), while in the second case memory goes up to 20 MB (from 7). In both cases, when I remove the CGContextDrawPDFPage(context, page); line memory is (nearly) constant at 6 MB during and after all preparations of documents. Can anybody explain whats going on there?

  • What are the restrictions for the name of an application when submitting to App Store ?

    - by Patrick
    Hello, I have just finished my application for iPhone. I would like to know if it is possible to use the word iPhone in the name of the application. For example, can I name my application iPhonesque ? And for the icon, can I use graphics related to Apple like a Mac Windows (with the three buttons, red, yellow and green) on snow leopard background ? Thank you very much for your answers.

  • How to make Android not to recycle my Bitmap until I don't need it?

    - by RankoR
    I'm getting drawing cache of the view, that is set as contentView to the Activity. Then I set new content view to the activity and pass that drawing cache to it. But Android recycles my bitmaps and I'm getting this exception: 06-13 01:58:04.132: E/AndroidRuntime(15106): java.lang.RuntimeException: Canvas: trying to use a recycled bitmap android.graphics.Bitmap@40e72dd8 Any way to fix it? I had an idea to extend Bitmap class, but it's final. Why GC is recycling it?

  • Use OpenGL ES to create an iPhone painting tool?

    - by Jeff
    Is it feasible to use OpenGL ES to create an iPhone raster graphics editor like SketchBook Mobile(http://usa.autodesk.com/adsk/servlet/pc/item?siteID=123112&id=13872203)? Any related reference(tutorial, sample) you can recommend? Why I try to use OpenGL ES? Because it's hardware accelerated and cross-platform. Thanks in advance!

  • program R- in ggplot restrict y to be >0 in LOESS plot

    - by Nate
    Here's my code: qplot(data=sites, x, y, main="Site 349") (p <- qplot(data = sites, x, y, xlab = "", ylab = "")) (p1 <- p + geom_smooth(method = "loess",span=0.5, size = 1.5)) p1 + theme_bw() + opts(title = "Site 349") Some of the LOESS lines and confidence intervals go below zero, but I would like to restrict the graphics to 0 and positive numbers (because negative do not make sense). How can I do this?

  • Should I Abandon Adobe Flash for HTML5 and <canvas> ?

    - by helpmarnie
    I'm currently looking into developing Facebook applications and was planning on using Flash as the basis of my application, I have test built some simple PHP Facebook applications and I know enough about action-script 3 to start me on my way, but the API for Facebook development in AS looks far more tedious than the PHP one. my question is would I be able to create interactive graphics (games) like we see across the web in the HTML5 canvas class? and which would be simpler?

  • Error:A generic error occurred in GDI+

    - by sanfra1983
    Hi, I created a web project on the server, and when I upload an image shows me the error Error: A generic error occurred in GDI +. I have read many links on the net that talk about this issue, and although I made the changes, nothing went wrong. I was thinking if the case is not an issue of permissions to folders. In fact I have two folders one inside the other. This is the code to resize the image: public Bitmaps ResizeImage (Stream stream, int? width, int? height) ( System.Drawing.Bitmap bmpOut = null; const int defaultWidth = 800; const int defaultHeight = 600; int width = lnWidth == null? defaultWidth: (int) width; int height = lnHeight == null? defaultHeight: (int) height; try ( LoBMP bitmap = new Bitmap (stream); ImageFormat loFormat = loBMP.RawFormat; decimal lnRatio; lnNewWidth int = 0; lnNewHeight int = 0; if (loBMP.Width <& & lnWidth loBMP.Height <lnHeight) ( loBMP return; ) if (loBMP.Width> loBMP.Height) ( lnRatio = (decimal) lnWidth / loBMP.Width; lnNewWidth = lnWidth; decimal = lnTemp loBMP.Height lnRatio *; lnNewHeight = (int) lnTemp; ) else ( lnRatio = (decimal) lnHeight / loBMP.Height; lnNewHeight = lnHeight; decimal = lnTemp loBMP.Width lnRatio *; lnNewWidth = (int) lnTemp; ) bmpOut = new Bitmap (lnNewWidth, lnNewHeight); Graphics g = Graphics.FromImage (bmpOut); g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic; g.FillRectangle (Brushes.White, 0, 0, lnNewWidth, lnNewHeight); g.DrawImage (loBMP, 0, 0, lnNewWidth, lnNewHeight); loBMP.Dispose (); ) catch ( return null; ) bmpOut return; ) and this is the code that I insert in the codebehind: string filepath = AppDomain.CurrentDomain.BaseDirectory + img_veterinario / "; string = filepathM AppDomain.CurrentDomain.BaseDirectory + img_veterinario / img_veterinarioM; Reseize Reseize R = new (); Bitmap = photosFileOriginal r.ResizeImage (fucasiclinici.PostedFile.InputStream, 400, 400); Bitmap = photosFileMiniatura r.ResizeImage (fucasiclinici.PostedFile.InputStream, 72, 72); String filename = Path.GetFileName (fucasiclinici.PostedFile.FileName); photosFileOriginal.Save (Path.Combine (filepath, filename)); photosFileMiniatura.Save (Path.Combine (filepathM, filename)); Can you help me? Thanks

  • Using CreateOrthographicOffCenter in XNA

    - by Jeffrey Kern
    I'm trying to figure out how to draw graphics in XNA, and someone else suggested this. But before I attempt to use this... If I create and use this camera, and set LEFT,TOP to 0 and WIDTH=256 and HEIGHT=240, anything I render to the screen will use these coordinates? So a box with a width and height of 1, if set to 0,0 will take up space from 0,0 to 1,1?

  • Best windows iphone app development alternative

    - by Nash0
    What do you think is the best way to develop iphone apps on windows? What are the pros / cons of your method, and why do you use it over other options? How complex is your method in relation to other options? I am more interested in standalone and web apps but fell free to discuss gaming graphics. Yes I know you need to build on a mac to be able to put it on the app store, so no "use a mac" answers please.

  • Calculating the Angle Between Two vectors Using Dot Product

    - by P. Avery
    I'm trying to calculate the angle between two vectors so that I can rotate a character in the direction of an object in 3D space. I have two vectors( character & object), loc_look, and modelPos respectively. For simplicity's sake I am only trying to rotate along the up axis...yaw. loc_look = D3DXVECTOR3 (0, 0, 1), modelPos = D3DXVECTOR3 (0, 0, 15); I have written this code which seems to be the correct calculations. My problem arises, seemingly, because the rotation I apply to the character's look vector(loc_look) exceeds the value of the object's position (modelPos). Here is my code: BOOL CEntity::TARGET() { if(graphics.m_model->m_enemy) { D3DXVECTOR3 modelPos = graphics.m_model->position; D3DXVec3Normalize(&modelPos, &modelPos); //D3DXVec3Normalize(&loc_look, &loc_look); float dot = D3DXVec3Dot(&loc_look, &modelPos); float yaw = acos(dot); BOOL neg = (loc_look.x > modelPos.x) ? true : false; switch ( neg ) { case false: Yaw(yaw); return true; case true: Yaw(-yaw); return true; } } else return false; } I rotate the character's orientation matrix with the following code: void CEntity::CalculateOrientationMatrix(D3DXMATRIX *orientationMatrix) { D3DXMatrixRotationAxis(&rotY, &loc_up, loc_yaw); D3DXVec3TransformCoord(&loc_look, &loc_look, &rotY); D3DXVec3TransformCoord(&loc_right, &loc_right, &rotY); D3DXMatrixRotationAxis(&rotX, &loc_right, loc_pitch); D3DXVec3TransformCoord(&loc_look, &loc_look, &rotX); D3DXVec3TransformCoord(&loc_up, &loc_up, &rotX); D3DXMatrixRotationAxis(&rotZ, &loc_look, loc_roll); D3DXVec3TransformCoord(&loc_up, &loc_up, &rotZ); D3DXVec3TransformCoord(&loc_right, &loc_right, &rotZ); *orientationMatrix *= rotX * rotY * rotZ; orientationMatrix->_41 = loc_position.x; orientationMatrix->_42 = loc_position.y; orientationMatrix->_43 = loc_position.z; //D3DXVec3Normalize(&loc_look, &loc_look); SetYawPitchRoll(0,0,0); // Reset Yaw, Pitch, & Roll Amounts } Also to note, the modelPos.x increases by 0.1 each iteration so the character will face the object as it moves along the x-axis... Now, when I run program, in the first iteration everything is fine(I haven't rotated the character yet). On the second iteration, the loc_look.x value is greater than the modelPos.x value(I rotated the character too much using the angle specified with the dot product calculations in the TARGET function). Therefore on the second iteration my code will rotate the character left to adjust for the difference in the vectors' x values... How can I tighten up the measurements so that I do not rotate my character's look vector by too great a value?
