  • middle click works only once

    - by Ivan Peevski
    Just recently I'm having problems with middle click. After a reboot, it works the first time I use it, but then it doesn't work after that. As far as I've investigated, that's the same on Linux and Windows. The mouse is Reaper ZMS-1000. To me it sounds like a hardware issue, but it's strange that it works after a reboot every time just for one time. Any suggestions?

  • scary islamic messages on mouse in libreoffice - a virus?

    - by yuvi
    This is weird. Today I opened an excel file with libre office. Suddenly I saw the mouse changed color, and stuck to it was a message in Arabic, which changed every second in a loop. I can actually read Arabic so I immediatly recognized it as Islamic messages praising Allah (including the Takbir). Here's a screenshot: At first I thought this was something with the file, but then I saw that this happens with any libre office program (but only libre-office programs), and even when they're open, it only changes the mouse when it's hovering over the libre program, and goes back to normal anywhere else. Also, re-installing did not help. I tried running software updater - but I got an error where it couldn't load some steam repositories, but that seems like a coincidence: Failed to fetch http://repo.steampowered.com/steam/dists/precise/steam/i18n/Translation-en_US Failed to fetch http://repo.steampowered.com/steam/dists/precise/steam/i18n/Translation-en Here's another hint - I tried taking several screenshots of several messages, but they all ended up showing the same message (the one above). Hopefully that means anything. I should note I haven't installed anything fishy lately, and I hardly ever use libre office at all (I prefer Google Drive whenever I need to work with documents), so I'm really unsure as to how this happened. Anyway, this is scary. Any help would be greatly appreciated!

  • What sort of data should be sent for mouse-based movement in a multiplayer game?

    - by Daniel
    I'm new to the Multiplayer Rodeo here so please bear with me... I am just getting started and I'm trying to figure out how to deal with movement. I've looked at the question Best way to implement mouse-based movement in MMOG which gives me a pretty good idea, but I'm still struggling with what kind of data should be sent to the server. If a player is on position [x:0, y:0] and I click with the mouse on [x:40, y:40] to start movement, what information should I send to the server? Should I calculate the position based on velocity on client side and just send the expected location? Or should I send current location and velocity and direction? When the server is updating the clients on the players' whereabouts, should the position be sent only, and the clients expected to interpolate/predict movement, or can the direction sent from the client (instead of just coordinates) be used. My concern(or confusion) is regarding the ping/lag frequency of data update and use of a predictive algorithm, as I'd like the movement to be smooth even with a high latency, and prevent ability to cheat(though that's not the top priority).

  • Can't slow down the pointer speed enough

    - by murat güler
    I have changed my mouse, bought a new set but still no use - it's too fast for a designer. And in the new version (12.04) I don't even know how to find the xorg.conf, or anything would help Is not there any application for this to adjust mouse sensivity more than the default options like Logitech applications for Windows?

  • wpf: capturing mouse does not work

    - by amethyste
    hello I am developing an kind of outlook calendar application where I need to make the appointment resizable from mouse. My first try with a thumb did not work properly so I tried another way. What I did is that: 1) on the botton of the appointmennt panel I added a rectangle to figure out the resize zone (the thumb). The appointment panel is put on a grid panel. 2) I intercept down event on the rectangle and send event to this code: private Point startPoint; private void OnResizeElementMouseDown(object sender, MouseButtonEventArgs e) { e.Handled = true; this.MouseMove += new MouseEventHandler(ResizeEndElement_MouseMove); this.MouseLeftButtonUp += new MouseButtonEventHandler(OnResizeElementMouseUp); // some code to perform new height computation Mouse.Capture(this); } where this is the appointment panel that own the thumb. Decreasing height works well. But increasing is more difficult. If I move the mouse very very slowly it's OK, if I speed it up a little bit it tends to leave out the appointment panel and then all MouseMove event are lost. I thought Mouse.Capture() was propose to solve this kind of problem, but in fact not. Does anybody know what is wrong in my code?

  • Make Your Mouse Pointers Left-hand Friendly

    - by Matthew Guay
    It’s a right-centric world, with everything from pencils to computer mice expecting you to be right-handed.  Here’s how you can train your mouse and cursors in Windows 7 and Vista to respect your left-handedness. Using your Left Hand the Right Way It’s easy to switch your mouse to left-handed mode.  Enter “mouse” in your Start menu search, and select the first entry. Check the “Switch primary and secondary buttons” box to make your mouse more left-hand friendly.  Now your primary select button is your right button, and the secondary button (commonly referred to as right-click) is the left button. But, it can still be awkward to select items on screen with your left hand using the default cursors.  MSDN has a free set of cursors designed for left-handed users, that can fix this problem for you.  These cursors are exactly like the default Aero cursors in Windows 7 and Vista, except they are reversed to make them better for left-handed use. The cursors are available in 3 sizes: normal, large, and extra large.  The normal ones are the same size as the default ones in Windows 7; feel free to choose the other sizes if you prefer them.  Click each link to download all 6 cursors for your size (link below). Click “I Agree” after selecting the cursors to accept the license agreement and download them. Once you have all 6 cursors downloaded, select the Pointers tab in the Mouse Properties dialog.  Click the cursor to change, and then click Browse to select the new cursor. Browse to the folder you downloaded your new cursors to, select the correct cursor, and click Open. Do this for each of the 6 cursors to be changed.  Strangely, the Busy cursor (the spinning blue orb) is a static cursor, so you may not wish to change it.  All the other ones look and act like their standard counterparts. Here’s the cursors to be changed, and their equivalents in the default cursors: Normal Select: aero_arrow_left.cur Help Select: aero_helpsel_left.cur Working in Background: aero_working_left.ani Busy: aero_busy_left.cur Handwriting: aero_pen_left.cur Link Select: aero_link_left.cur After changing all the cursors, click Save As… to save this mouse scheme so you can easily select it in the future.  Finally click Ok to close the Mouse Properties dialog and accept the changes. Now your pointers will be easier to use left-handed! Conclusion Whether you’re right-handed or left-handed, you can enjoy the Aero cursors in Windows 7 or Vista in the way that works best for you.  Unfortunately, many mice are still designed for right-handed people, but this trick will help you make the best out of your mouse. We included all of the 6 cursors for you in a zip file you can download Here. This will make it easier for you to get them all together without having to download them individually.

  • Getting Custom NSCell with NSButtonCell instance to handle mouse click/mouse events

    - by sidha
    OK I'm really stumped on this one. I want to make a checkbox with a NSTextFieldCell combined together. It's important that the checkbox goes ON if the mouse hits the box, NOT the text. I've accomplished this, more or less, but the issue is receiving the mouse event because I click one checkbox in a row, but ALL of them turn to NSOnState. I will show what I've done and my various failed attempts in order to get this to work. So this is how I've done it so far: header: @interface MyCheckboxCellToo : NSTextFieldCell { NSButtonCell *_checkboxCell; } implementation: - (NSUInteger)hitTestForEvent:(NSEvent *)event inRect:(NSRect)cellFrame ofView:(NSView *)controlView { NSPoint point = [controlView convertPoint:[event locationInWindow] fromView:nil]; NSLog(@"%@", NSStringFromPoint(point)); NSRect checkFrame; NSDivideRect(cellFrame, &checkFrame, &cellFrame, cellFrame.size.height/*3 + [[_checkboxCell image] size].width*/, NSMinXEdge); if (NSMouseInRect(point, checkFrame, [controlView isFlipped])) { // the checkbox, or the small region around it, was hit. so let's flip the state NSCellStateValue checkState = ([_checkboxCell state] == NSOnState) ? NSOffState:NSOnState; [self setState:checkState]; [_checkboxCell setState:checkState]; [controlView setNeedsDisplay:YES]; return NSCellHitTrackableArea; } return [super hitTestForEvent:event inRect:cellFrame ofView:controlView]; } I know I probably shouldn't be doing: [self setState:checkState]; [_checkboxCell setState:checkState]; [controlView setNeedsDisplay:YES]; in there... because the result is that EVERY checkbox in every goes to NSOnState. Is this because cells are re-used? How come the ImageAndTextCell can have different images in the same tableview? How do I handle the mouse event? I have tried: - (BOOL)trackMouse:(NSEvent *)theEvent inRect:(NSRect)cellFrame ofView:(NSView *)controlView untilMouseUp:(BOOL)untilMouseUp { NSLog(@"%s %@", _cmd, theEvent); return [_checkboxCell trackMouse:theEvent inRect:cellFrame ofView:controlView untilMouseUp:untilMouseUp]; // return YES; // return [super trackMouse:theEvent inRect:cellFrame ofView:controlView untilMouseUp:untilMouseUp]; } - (BOOL)startTrackingAt:(NSPoint)startPoint inView:(NSView *)controlView { NSLog(@"%s %@", _cmd, NSStringFromPoint(startPoint)); return [super startTrackingAt:startPoint inView:controlView]; } - (BOOL)continueTracking:(NSPoint)lastPoint at:(NSPoint)currentPoint inView:(NSView *)controlView { NSLog(@"%s %@", _cmd, NSStringFromPoint(currentPoint)); return [super continueTracking:lastPoint at:currentPoint inView:controlView]; } - (void)stopTracking:(NSPoint)lastPoint at:(NSPoint)stopPoint inView:(NSView *)controlView mouseIsUp:(BOOL)flag { NSLog(@"%s %d %@", _cmd, flag, NSStringFromPoint(stopPoint)); } trackMouse: ... DOES gets called but startTrackingAt:..., continueTracking:..., and stopTracking:.... DO NOT get called when I click on the checkbox "hit area" in trackMouse:... I have tried return [_checkboxCell trackMouse:theEvent inRect:cellFrame ofView:controlView untilMouseUp:untilMouseUp]; and return [super trackMouse:theEvent inRect:cellFrame ofView:controlView untilMouseUp:untilMouseUp]; and neither seems to result in the mouse event being handled by the checkbox. How do I get that single checkbox to go NSOnState? I know I'm pretty close but after a lot of doc reading and google searching I haven't been successful at solving this. suggestions and comments welcome.. OK here is a bit more to show creation and destruction of the object.. - (id)init { if ((self = [super init])) { _checkboxCell = [[NSButtonCell alloc] init]; [_checkboxCell setButtonType:NSSwitchButton]; [_checkboxCell setTitle:@""]; [_checkboxCell setTarget:self]; [_checkboxCell setImagePosition:NSImageLeft]; [_checkboxCell setControlSize:NSRegularControlSize]; } return self; } - copyWithZone:(NSZone *)zone { MyCheckboxCellToo *cell = (MyCheckboxCellToo *)[super copyWithZone:zone]; cell->_checkboxCell = [_checkboxCell copyWithZone:zone]; return cell; } - (void)dealloc { [_checkboxCell release]; [super dealloc]; }

  • Why does the mouse always move to the bottom left?

    - by AngryHacker
    In the course of doing stuff on the computer, the mouse always moves, by itself, to the bottom left of the screen - I'd say several times in the course of an hour. I thought this might be an issue with the driver, so I re-installed the driver, but the problem continued. Then thinking that the mouse is faulty, I replaced my Microsoft Wheel Mouse with a Dell mouse. The problem still continues. How can I fix this problem?

  • Mouse interaction in ListBoxItem children (WPF)

    - by absence
    I have a ListBox with an ItemTemplate that contains a control that interacts with the mouse. This interfers with the selection functionality of the ListBox, i.e. clicking a control does not select the item. This is because ListBoxItem sets the Handled property of the mouse event to true in OnMouseLeftButtonDown. I tried the following protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); e.Handled = false; } but the ListBoxItem “takes over” the mouse and prevents the control from doing its own interaction. Then I had another idea protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); ((ListBoxItem)VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(this)))).IsSelected = true; } which actually works, but feels more like an ugly kludge than an elegant solution. Are there any better solutions that don't rely on the exact contents of the visual tree?

  • Mouse configurable buttons for programming

    - by DavRob60
    Different mouse models has been already discussed. But all these mouse got configurable buttons. Has a programmer, how do you set them? I use The Microsoft Intellimouse Optical. So set the Left side button to "Copy" and the Right side button to "Paste". I did not set the Wheel click to anything. I'm curious to see if there is any better setup? UPDATE : I'm trying to find some interesting key I could map to my mouse buttons. Copy & paste are the best I' found so far, but i just want to know if there is something that could be more useful when programming.

    I designed a Share Point page in Share Point Designer. ( I cannot upload anything to the servers or no chance to use add-ons) Since it is requested I have to change the shape of mouse cursor. Some purple bubbles or a logo should follow the original mouse cursor when I move the mouse. How can do this? If I find the code where (in which file) should I put it? Can it be done with site based design? Thank you very much

  • How to move the mouse

    - by GroundZero
    I'm making a little bot in C#. At the moment it works pretty well, it can load text from a file and type it for you. But for now, I need to manualy click the textfield to put the focus on it, remaximize my form and then click the Type-button. After the typing, I need to manualy slide the scorebar and press submit. I'd like to know how I can move my mouse with C# and if possible, if possible I'd like to load the mouse positions from a xml-file. I need to move to the textfield, click in it to focus on it, start the type script, move to the slider, hold the mouse down on it while dragging, releasing it on the correct position & clicking on the submitbutton This is what I have for now: To load in the variables, I'm using this script: private void Initialize() { XmlTextReader reader = new XmlTextReader(Application.StartupPath + @"..\..\..\CursorPositions.xml"); while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: // The node is an element. element = reader.Value; break; case XmlNodeType.Text: //Display the text in each element. switch (element) { case "Textbox-X": textX = int.Parse(reader.Value); break; case "Textbox-Y": textY = int.Parse(reader.Value); break; case "SliderBegin-X": sliderX = int.Parse(reader.Value); break; case "SliderBegin-Y": sliderY = int.Parse(reader.Value); break; case "SubmitButton-X": submitX = int.Parse(reader.Value); break; case "SubmitButton-Y": submitY = int.Parse(reader.Value); break; } break; } } This is the xml-file: <?xml version="1.0" encoding="utf-8" ?> <CursorPositions> <Textbox-X>430</Textbox-X> <Textbox-Y>270</Textbox-Y> <SliderBegin-X>430</SliderBegin-X> <SliderBegin-Y>470</SliderBegin-Y> <SubmitButton-X>860</SubmitButton-X> <SubmitButton-Y>365</SubmitButton-Y> </CursorPositions> To move the mouse I'm using this piece of code: public partial class FrmMain : Form { [System.Runtime.InteropServices.DllImport("user32.dll")] public static extern void mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo); public const int MOUSEEVENTF_LEFTDOWN = 0x0002; public const int MOUSEEVENTF_LEFTUP = 0x0004; public const int MOUSEEVENTF_RIGHTDOWN = 0x0008; public const int MOUSEEVENTF_RIGHTUP = 0x0010; ... private void btnStart_Click(object sender, EventArgs e) { // start button (de)activates loop if (!running) { btnStart.Text = "Stop"; btnStart.Cursor = Cursors.No; running = true; } else { btnStart.Text = "Start"; btnStart.Cursor = Cursors.AppStarting; running = false; } while (running) { // move to textbox & type Cursor.Position = new Point(textX, textY); mouse_event(MOUSEEVENTF_LEFTDOWN, textX, textY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, textX, textY, 0, 0); Type(); // wait 90 seconds till slider available Thread.Sleep(90 * 1000); // move to slider & slide according to score Cursor.Position = new Point(sliderX, sliderY); mouse_event(MOUSEEVENTF_LEFTDOWN, sliderX, sliderY, 0, 0); Cursor.Position = new Point(sliderX + 345 / 10 * score, sliderY); mouse_event(MOUSEEVENTF_LEFTUP, sliderX + 345 / 10 * score, sliderY, 0, 0); // submit Cursor.Position = new Point(submitX, submitY); mouse_event(MOUSEEVENTF_LEFTDOWN, submitX, submitY, 0, 0); mouse_event(MOUSEEVENTF_LEFTUP, submitX, submitY, 0, 0); // wait 10 sec to be sure it's submitted Thread.Sleep(10 * 1000); // refresh page SendKeys.SendWait("{F5}"); // get new text NewText(); // wait 10 sec to refresh and load song Thread.Sleep(10 * 1000); } } } PS: I get the coordinates via my form. I've got 2 labels that show my X & Y coordinates. To capture them outside the form, I press and hold my Left Mouse Button and 'drag' it outside the form to the correct place. This way I get the coordinates of my mouse outside the form

  • How can I use my keyboard as a mouse?

    - by Michael Durrant
    I'm using my keyboard more and more these days for basic command line stuff, vim editing, alt-tab window switching and the like. Q) How can I use my number pad keys to move the cursor around on the screen without using the mouse? I looked to try and install btnx as mentioned by others but it doesn't seem to exist anymore as an available package I also tried shift-numlock as mentioned by another but that didn't work either (just turns numlock on/off).

  • 3D Ray Casting / Picking

    Hi, I am not sure if I should post this link, but I feel this falls into game development just as much as it does math. I have a ray cast's far and near values and I am trying to calculate the end point of the ray so that I can either draw a line to show the ray, or render an object at the end of 3d mouse position. Here is my post on the stack overflow math site, if there is a problem with me doing this just close the thread. Thank you. http://math.stackexchange.com/questions/15918/help-with-matrix-mathematica

  • Drag camera/view in a 3D world

    - by Dono
    I'm trying to make a Draggable view in a 3D world. Currently, I've made it using mouse position on the screen, but, when I move the distance traveled by my mouse is not equal to the distance traveled in the 3D world. So, I've tried to do that : Compute a ray from mouse position to 3D world. Calculate intersection with the ground. Check intersection difference old position <- new position. Translate camera with the difference. I've got a problem with this method: The ray is computed with the current camera's position I move the camera I compute the new ray with new camera position. The difference between old ray and new ray is now invalid. So, graphically my camera don't stop to move to previous/new position everytime. How can I do a draggable camera with another solution ? Thanks!

  • Dual boot 12.04 and W7 - keybaord and screen not responsive

    - by Saariko
    I installed 12.04 using WUBI on a working W7 64bit system. both KB and mouse work perfect during the BIOS boot, and on the bootmgr, I can select Windows 7 or Ubuntu to load. Once I select Ubuntu, the KB and mouse seem to loose their power (light on the mouse and Numlock leds go off) After couple of seconds, the screen gets blurry. The screen pops back at the Ubuntu login screen, the mouse gets activated (light works, as well as mouse pointer is moving) However, the keyboard is not responsive to any click, nor does any icon on the login screen. - Using the mouse, I can't select the virtual keyboard, nor the shutdown icon - like it's not accepting any mouse clicks. The following Q&A didn't answer: Keyboard not responding at login with 12.04 dual boot on toshiba satellite L775 which links to a post on the web I also tried 12.04 - Windows 7 Dual boot - not responding to keyboard in boot menu - that goes beyond the login screen, but still didnt' assist me. It's a wired USB KB The board is an Intel board, and there isn't even a PS/2 connection anymore. Tried moving around the USB's Tried removing the Mouse, and only have the KB. Neither helped.

  • Scaling an image using the mouse in C#

    - by Gaax
    Hey guys... I'm trying to use the position of the mouse to calculate the scaling factor for scaling an image. Basically, the further you get away from the center of the image, the bigger it gets; and the closer to the center you get, the smaller it gets. I have some code so far but it's acting really strange and I have absolutely no more ideas. First I'll let you know, one thing I was trying to do is average out 5 distances to get a more smooth resize animation. Here's my code: private void pictureBoxScale_MouseMove(object sender, MouseEventArgs e) { if (rotateScaleMode && isDraggingToScale) { // For Scaling int sourceWidth = pictureBox1.Image.Width; int sourceHeight = pictureBox1.Image.Height; float dCurrCent = 0; // distance between the current mouse pos and the center of the image float dPrevCent = 0; // distance between the previous mouse pos and the center of the image System.Drawing.Point imgCenter = new System.Drawing.Point(); imgCenter.X = pictureBox1.Location.X + (sourceWidth / 2); imgCenter.Y = pictureBox1.Location.Y + (sourceHeight / 2); // Calculating the distance between the current mouse location and the center of the image dCurrCent = (float)Math.Sqrt(Math.Pow(e.X - imgCenter.X, 2) + Math.Pow(e.Y - imgCenter.Y, 2)); // Calculating the distance between the previous mouse location and the center of the image dPrevCent = (float)Math.Sqrt(Math.Pow(prevMouseLoc.X - imgCenter.X, 2) + Math.Pow(prevMouseLoc.Y - imgCenter.Y, 2)); if (smoothScaleCount < 5) { dCurrCentSmooth[smoothScaleCount] = dCurrCent; dPrevCentSmooth[smoothScaleCount] = dPrevCent; } if (smoothScaleCount == 4) { float currCentSum = 0; float prevCentSum = 0; for (int i = 0; i < 4; i++) { currCentSum += dCurrCentSmooth[i]; } for (int i = 0; i < 4; i++) { prevCentSum += dPrevCentSmooth[i]; } float scaleAvg = (currCentSum / 5) / (prevCentSum / 5); int destWidth = (int)(sourceWidth * scaleAvg); int destHeight = (int)(sourceHeight * scaleAvg); // If statement is for limiting the size of the image if (destWidth > (currentRotatedImage.Width / 2) && destWidth < (currentRotatedImage.Width * 3) && destHeight > (currentRotatedImage.Height / 2) && destWidth < (currentRotatedImage.Width * 3)) { AForge.Imaging.Filters.ResizeBilinear resizeFilter = new AForge.Imaging.Filters.ResizeBilinear(destWidth, destHeight); pictureBox1.Image = resizeFilter.Apply((Bitmap)currentRotatedImage); pictureBox1.Size = pictureBox1.Image.Size; pictureBox1.Refresh(); } smoothScaleCount = -1; } prevMouseLoc = e.Location; currentScaledImage = pictureBox1.Image; smoothScaleCount++; } }

  • Unable to drag and drop / select multiple with mouse

    - by J. Scott Elblein
    I'm running into a perplexing issue with Windows 8 Pro x64, where randomly I'm unable to drag to select multiple files (i.e. in Explorer or Directory Opus). I've also noticed that a similar issue happens when I'm running for example Photoshop or Illustrator and can't drag to select multiple layers, or drag to do some other things in them. it happens randomly and have found no way to reliably reproduce it, but it happens VERY frequently. I have read some tips saying pressing the ESC button usually fixes the issue, but it doesn't in my case. From what I understand, it's probably due to some other process locking the drag feature somehow, but I've not found a way to tell which process is the perp; I've even tried using unlock software on files when I'm suddenly unable to drag and I'm told by it that nothing is locking it. Anyone have any ideas?

  • Converting openGl code to DirectX

    - by Fredrik Boston Westman
    First of all, this is kind of a follow up question on @byte56 excellent anwser on this question concerning picking algorithms. I'm trying to convert one of his code examples to directX 11 however I have run in to some problems ( I can pick but the picking is way off), and I wanted to make sure I had done it rigth before moving on and checking the rest of my code. I am not that familiar with openGl but I can imagine openGl has diffrent coordinations systems, and functions that alters how you must implement to code abit. This is his code example: public Ray GetPickRay() { int mouseX = Mouse.getX(); int mouseY = WORLD.Byte56Game.getHeight() - Mouse.getY(); float windowWidth = WORLD.Byte56Game.getWidth(); float windowHeight = WORLD.Byte56Game.getHeight(); //get the mouse position in screenSpace coords double screenSpaceX = ((float) mouseX / (windowWidth / 2) - 1.0f) * aspectRatio; double screenSpaceY = (1.0f - (float) mouseY / (windowHeight / 2)); double viewRatio = Math.tan(((float) Math.PI / (180.f/ViewAngle) / 2.00f))* zoomFactor; screenSpaceX = screenSpaceX * viewRatio; screenSpaceY = screenSpaceY * viewRatio; //Find the far and near camera spaces Vector4f cameraSpaceNear = new Vector4f((float) (screenSpaceX * NearPlane), (float) (screenSpaceY * NearPlane), (float) (-NearPlane), 1); Vector4f cameraSpaceFar = new Vector4f((float) (screenSpaceX * FarPlane), (float) (screenSpaceY * FarPlane), (float) (-FarPlane), 1); //Unproject the 2D window into 3D to see where in 3D we're actually clicking Matrix4f tmpView = Matrix4f(view); Matrix4f invView = (Matrix4f) tmpView.invert(); Vector4f worldSpaceNear = new Vector4f(); Matrix4f.transform(invView, cameraSpaceNear, worldSpaceNear); Vector4f worldSpaceFar = new Vector4f(); Matrix4f.transform(invView, cameraSpaceFar, worldSpaceFar); //calculate the ray position and direction Vector3f rayPosition = new Vector3f(worldSpaceNear.x, worldSpaceNear.y, worldSpaceNear.z); Vector3f rayDirection = new Vector3f(worldSpaceFar.x - worldSpaceNear.x, worldSpaceFar.y - worldSpaceNear.y, worldSpaceFar.z - worldSpaceNear.z); rayDirection.normalise(); return new Ray(rayPosition, rayDirection); } All rigths reserved to him of course This is my DirectX 11 code : void GraphicEngine::pickRayVector(float mouseX, float mouseY,XMVECTOR& pickRayInWorldSpacePos, XMVECTOR& pickRayInWorldSpaceDir) { float PRVecX, PRVecY; float nearPlane = 0.1f; float farPlane = 200.0f; floar viewAngle = 0.4 * 3.14; PRVecX = ((( 2.0f * mouseX) / ClientWidth ) - 1 ) * tan((viewAngle)/2); PRVecY = (1-(( 2.0f * mouseY) / ClientHeight)) * tan((viewAngle)/2); XMVECTOR cameraSpaceNear = XMVectorSet(PRVecX * nearPlane,PRVecY * nearPlane, -nearPlane, 1.0f); XMVECTOR cameraSpaceFar = XMVectorSet(PRVecX * farPlane,PRVecY * farPlane, -farPlane, 1.0f); // Transform 3D Ray from View space to 3D ray in World space XMMATRIX invMat; XMVECTOR matInvDeter; invMat = XMMatrixInverse(&matInvDeter, cam->getCameraView()); //Inverse of View Space matrix is World space matrix XMVECTOR worldSpaceNear = XMVector3TransformCoord(cameraSpaceNear, invMat); XMVECTOR worldSpaceFar = XMVector3TransformCoord(cameraSpaceFar, invMat); pickRayInWorldSpacePos = worldSpaceNear; pickRayInWorldSpaceDir = worldSpaceFar-worldSpaceNear; pickRayInWorldSpaceDir = XMVector3Normalize(pickRayInWorldSpaceDir); } A couple of notes: The mouse coordinates are already converted so that the top left corner of the client window would be (0,0) and the bottom rigth (800,600) ( or whatever resolution you would have) I hadn't used any far or near plane before, so i just made some arbitrary number up for them. To my understanding it shouldnt matter as long as the object you are trying to pick is in between the range of thoese numbers The viewAngle is the same angle that I used when setting the camera view with XMMatrixPerspectiveFovLH , I just hadn't made it a member variable of my Camera class yet. I removed the variable aspectRation and zoomFactor because I assumed that they where related to some specific function of his game. Now I'm not sure, but I think the problems lies either withing the mouse to viewspace conversion, maby that we use diffrent coordinations systems. Either that or how i transform the matrixes in the the end, because i know order is important when it comes to matrixes. Any help is appriciated! Thanks in advance. Edit: One more note, my code is in c++
