• How to make an object stay relative to another object

  - by Nick

  In the following example there is a guy and a boat. They have both a position, orientation and velocity. The guy is standing on the shore and would like to board. He changes his position so he is now standing on the boat. The boat changes velocity and orientation and heads off. My character however has a velocity of 0,0,0 but I would like him to stay onboard. When I move my character around, I would like to move as if the boat was the ground I was standing on. How do keep my character aligned properly with the boat? It is exactly like in World Of Warcraft, when you board a boat or zeppelin. This is my physics code for the guy and boat: this.velocity.addSelf(acceleration.multiplyScalar(dTime)); this.position.addSelf(this.velocity.clone().multiplyScalar(dTime)); The guy already has a reference to the boat he's standing on, and thus knows the boat's position, velocity, orientation (even matrices or quaternions can be used).

• Configuration tools for multiple monitors for X / Linux

  - by richard

  I have Ubuntu 10.04 running gnome and two monitors. I am wondering if a can get a better multi-monitor configuration tool. The one I have, gnome-display-properties, has too many problems, including: When I swapped my monitors over, the narrower (external) one now on the left. There is a width calculation error, such that I have a virtual monitor the width of the wide-monitor on the narrow-monitor and part of the wide monitor. And a virtual narrow-monitor on the remainder of the wide-monitor. Also the visible mouse pointer does is not aligned with the active spot, an x offset of one monitor width. I would like, in approximate order of importance: nobugs. to be able to select which is primary monitor. to have multiple configurations. configurations to be automatically selected based on which monitors are attached. configurations to be cycled (reliably) when display mode key is pressed. when a display is deactivated, for windows to migrate to remaining monitors. option to not change display resolution when mirroring, but to use side/top blanking bars to pad out screen.

• Render on other render targets starting from one already rendered on

  - by JTulip

  I have to perform a double pass convolution on a texture that is actually the color attachment of another render target, and store it in the color attachment of ANOTHER render target. This must be done multiple time, but using the same texture as starting point What I do now is (a bit abstracted, but what I have abstract is guaranteed to work singularly) renderOnRT(firstTarget); // This is working. for each other RT currRT{ glBindFramebuffer(GL_FRAMEBUFFER, currRT.frameBufferID); programX.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, firstTarget.colorAttachmentID); programX.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, firstTarget.depthAttachmentID); programX.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); // quadBuffID is a VBO for a screen aligned quad. It is fine. programX.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS,0,4); programY.use(); glActiveTexture(GL_TEXTURE0); glBindTexture(GL_TEXTURE_2D, currRT.colorAttachmentID); // The second pass is done on the previous pass programY.setUniform1i("colourTexture",0); glActiveTexture(GL_TEXTURE1); glBindTexture(GL_TEXTURE_2D, currRT.depthAttachmentID); programY.setUniform1i("depthTexture",1); glBindBuffer(GL_ARRAY_BUFFER, quadBuffID); programY.vertexAttribPointer(POSITION_ATTRIBUTE, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_QUADS, 0, 4); } The problem is that I end up with black textures and not the wanted result. The GLSL programs program(X,Y) works fine, already tested on single targets. Is there something stupid I am missing? Even an hint is much appreciated, thanks!

• How to align text at the top left-hand corner?

  - by OverTheRainbow

  I'd like to use stylesheet instead of hard-coding HTML so that text within cells are aligned vertically, ie. text starts at the upper left-hand corner. However, neither of this works: <head> <link rel="STYLESHEET" href="display.css" type="text/css"> <style> td {vertical-align:top; font-size:x-small} td {vertical-align:text-top; font-size:x-small} </style> </head> Does someone know? Thank you. Edit: Problem solved. Turns out the HTML editor I'm using is a bit old and didn't display things as expected, but they do show OK in a modern browser with "vertical-align:top".

• Incorrect viewport on monitor everytime computer is booted

  - by doldertfo

  Hi, Every time I turn on my PC the viewport isn't aligned correctly on the screen - there is always a black strip on the right hand side. This is not a big issue as it can be resolved by pressing the menu button on the screen and doing a factory reset. However it is irritating having to do it every time. I am using a flat screen monitor with vga connections. The weird thing it never used to happen before with the tower Im using. Is potentially out of date drivers a problem? Thanks.

• Demystifying "chunked level of detail"

  - by Caius Eugene

  Just recently trying to make sense of implementing a chunked level of detail system in Unity. I'm going to be generating four mesh planes, each with a height map but I guess that isn't too important at the moment. I have a lot of questions after reading up about this technique, I hope this isn't too much to ask all in one go, but I would be extremely grateful for someone to help me make sense of this technique. 1 : I can't understand at which point down the Chunked LOD pipeline that the mesh gets split into chunks. Is this during the initial mesh generation, or is there a separate algorithm which does this. 2 : I understand that a Quadtree data structure is used to store the Chunked LOD data, I think i'm missing the point a bit, but Is the quadtree storing vertex and triangles data for each subdivision level? 3a : How is the camera distance usually calculated. When reading up about quadtree's, Axis-aligned bounding box's are mentioned a lot. In this case would each chunk have a collision bounding box to detect the camera or player is nearby? or is there a better way of doing this? (raycast maybe?) 3b : Do the chunks calculate the camera distance themselves? 4 : Does each chunk have the same "resolution". for example at top level the mesh will be 32x32, will each subdivided node also be 32x32. Example below:

• How can I pretty print erb in BBedit indenting rails tags and not just markup?

  - by Andres Diez

  I want to re-indent my code but the rails tags <% foo %> get aligned to the left with no indentation. What I'm using is: markup utilities format pretty print Does anyone know if there is a way to reconfigure this behavior? UPDATE: I just found this out but cant seem to get it working: "The 'Pretty print' option for Markup - Utilities - Format is now implemented internally using a Dreamweaver-style source format profile. This affords slightly prettier output than was possible before. Advanced users can override the factory format profile by placing an appropriately constructed file at ~/Library/Application Support/BBEdit/SourceFormat.profile." I opened the bbedit app package, found the file, copied it to the folder indicated in "application support" and tweaked the desired indentation width just as a test before touching anything else, and it doesnt seem to do anything.

• Is there a version of the Arial or Tahoma font with monospaced digits and spaces?

  - by rossmcm

  The digits in the Arial font supplied with Windows are monospaced, in that they each take up the same horizontal space, but they seem to have neglected to provide a "monospaced" version of the space character. This means that you can't format a column of digits right-justified in (say) 12 spaces and have the right-hand edge be aligned. For example: 1 12 123 1234 12345 1234567 12345678 123456789 1234567890 works because the font used for code examples has spaces the same width as digits. This however doesn't work if the same text is displayed in Arial (I can't demonstrate because I can't figure out how to defeat SU's reformatting at the moment!). It just so happens that with Tahoma 8 point you can cheat because a space is exactly half the number of pixels as a digit, but that is messy and very specific.

• In a 2D platform game, how to ensure the player moves smoothly over sloping ground?

  - by Kovsa

  See image: http://i41.tinypic.com/huis13.jpg I'm developing a physics engine for a 2D platform game. I'm using the separating axis theorem for collision detection. The ground surface is constructed from oriented bounding boxes, with the player as an axis aligned bounding box. (Specifically, I'm using the algorithm from the book "Realtime Collision Detection" which performs swept collision detection for OBBs using SAT). I'm using a fairly small (close to zero) restitution coefficient in the collision response, to ensure that the dynamic objects don't penetrate the environment. The engine mostly works fine, it's just that I'm concerned about some edge cases that could possibly occur. For example, in the diagram, A, B and C are the ground surface. The player is heading left along B towards A. It seems to me that due to inaccuracy, the player box could be slightly below the box B as it continues up and left. When it reaches A, therefore, the bottom left corner of the player might then collide with the right side of A, which would be undesirable (as the intention is for the player to move smoothly over the top of A). It seems like a similar problem could happen when the player is on top of box C, moving left towards B - the most extreme point of B could collide with the left side of the player, instead of the player's bottom left corner sliding up and left above B. Box2D seems to handle this problem by storing connectivity information for its edge shapes, but I'm not really sure how it uses this information to solve the problem, and after looking at the code I don't really grasp what it's doing. Any suggestions would be greatly appreciated.

• Leveraging ERP Investments with EPM and BI Solutions

  - by john.orourke(at)oracle.com

  Now that many organizations have implemented ERP systems to automate and integrate their operational processes, IT investments are beginning to shift to the management systems i.e. EPM and BI tools and applications that integrate data from multiple transactional systems.  These solutions automate and integrate the management processes and enable organizations to achieve "management excellence" becoming smarter, more agile and more aligned than their competitors.  In fact the results of a recent IDC survey indicate that "Organizations that have implemented performance management more broadly are nearly four times more likely to be among the most competitive organizations in their industry."  One example of an organization that is leveraging their ERP investments with Oracle EPM and BI solutions is General Dynamics.  The Business Intelligence Collaborative (BIC) group within General Dynamics' IT organization assists various business units with the implementation, application support, and application hosting for their Business Intelligence and Enterprise Performance Management Applications.  Attend the Oracle Virtual Trade Show "Spotlight on Customer Success" on February 3rd to hear the details of how General Dynamics is using Oracle Essbase, Hyperion Planning, and Oracle BI to improve their planning, reporting and analysis processes and leverage their investments in Oracle E-Business Suite and other operational systems.   During the event, you can also hear about the latest developments and plans for Oracle Applications products, as well as what's coming with Oracle Fusion Applications. Here's a link to the Virtual Trade Show event overview and registration page.  The event runs from 8AM - 1PM PST/11AM - 4PM EST, and the EPM session is 10:30 - 11AM PST/1:30 - 2PM EST.    http://event.on24.com/event/26/79/15/rt/opFb.html?partnerref=internal I hope you'll join us on February 3rd!

• Static "LoD" hack opinions

  - by David Lively

  I've been playing with implementing dynamic level of detail for rendering a very large mesh in XNA. It occurred to me that (duh) the whole point of this is to generate small triangles close to the camera, and larger ones far away. Given that, rather than constantly modifying or swapping index buffers based on a feature's rendered size or distance from the camera, it would be a lot easier (and potentially quite a bit faster), to render a single "fan" or flat wedge/frustum-shaped planar mesh that is tessellated into small triangles close to the near or small end of the frustum and larger ones at the far end, sort of like this (overhead view) (Pardon the gap in the middle - I drew one side and mirrored it) The triangle sizes are chosen so that all are approximately the same size when projected. Then, that mesh would be transformed to track the camera so that the Z axis (center vertical in this image) is always aligned with the view direction projected into the XZ plane. The vertex shader would then read terrain heights from a height texture and adjust the Y coordinate of the mesh to match a height field that defines the terrain. This eliminates the need for culling (since the mesh is generated to match the viewport dimensions) and the need to modify the index and/or vertex buffers when drawing the terrain. Obviously this doesn't address terrain with overhangs, etc, but that could be handled to a certain extent by including a second mesh that defines a sort of "ceiling" via a different texture. The other LoD schemes I've seen aren't particularly difficult to implement and, in some cases, are a lot more flexible, but this seemed like a decent quick-and-dirty way to handle height map-based terrain without getting into geometry manipulation. Has anyone tried this? Opinions?

• Having trouble with projection matrix, need help

  - by Mr.UNOwen

  I'm having trouble with what appears to be the projection matrix. Given a wide enough of a screen, when a cube is on the left and right most edge, the left or right wall will appear stretched to the point that the front face is 1/10 the width of the side. So I do update the screen ratio along with the projection matrix and view port on screen resize, am I safe to assume all the trouble is from the matrix class? Also the cube follows the mouse, but it's only vertically aligned and ahead of the mouse when going left or right from the center of the screen. Perspective function call: * setPerspective * * @param fov: angle in radians * @param aspect: screen ratio w/h * @param near: near distance * @param far: far distance **/ void APCamera::setPerspective(GMFloat_t fov, GMFloat_t aspect, GMFloat_t near, GMFloat_t far) { GMFloat_t difZ = near - far; GMFloat_t *data; mProjection->clear(); //set to identity matrix data = mProjection->getData(); GMFloat_t v = 1.0f / tan(fov / 2.0f); data[_AP_MAA] = v / aspect; data[_AP_MBB] = v; data[_AP_MCC] = (far + near) / difZ; data[_AP_MCD] = -1.0f; data[_AP_MDD] = 0.0f; data[_AP_MDC] = 2.0f * far * near/ difZ; mRatio = aspect; mInvProjOutdated = true; mIsPerspective = true; } and... #define _AP_MAA 0 #define _AP_MAB 1 #define _AP_MAC 2 #define _AP_MAD 3 #define _AP_MBA 4 #define _AP_MBB 5 #define _AP_MBC 6 #define _AP_MBD 7 #define _AP_MCA 8 #define _AP_MCB 9 #define _AP_MCC 10 #define _AP_MCD 11 #define _AP_MDA 12 #define _AP_MDB 13 #define _AP_MDC 14 #define _AP_MDD 15

• Desktop switcher appears to be broken for quick double-switches

  - by Jon Blackburn

  I'm wondering if anyone else has seen this. I have three virtual desktops aligned in a horizontal row. In the middle desktop I have only a single application window. I have keyboard shortcuts mapping to navigate between the desktops. Obviously, I never use the up/down arrows because I only have one row of workspaces. Here's the problem, which only started to happen after I installed 12.04.1: When I rapidly hit to go from workspace 1 to workspace 3, the window on workspace 2 gets moved to workspace 1. I have checked using both Unity and Gnome3, and the behavior is the same under both. If I change back to the default workspace setup (a 2x2 grid of desktops) things seem to settle down (i.e., no wandering windows). Not every type of application window behaves the same way. I couldn't get a Chrome browser to jump from 2 to 1, but both Terminal and Terminator exhibit the behavior. Any thoughts? Better workarounds? Thanks in advance.

• PHP on IIS7 not showing pages

  - by Jeff

  I have a PHP website on a Windows 7 machine I'm working with and it cannot be viewed by any browser - IE, Chrome, Firefox. When navigating to the root of the website (default index.php) the browser reports it cannot find the address. Not a 404 error from the webserver, just as if it cannot resolve the name. Other websites in the same default web application that are also PHP work perfectly. I've aligned all folder permissions and everything else but this has got me stumped. I even went as far to create a new folder and throw in a test phpinfo() page and it worked. Copied this website's content to the new folder and it cannot find the index.php page. I checked all setting I know and can't seem to find what I'm missing. Anyone else encounter this issue? Remember the fix for it?

• vector rotations for branches of a 3d tree

  - by freefallr

  I'm attempting to create a 3d tree procedurally. I'm hoping that someone can check my vector rotation maths, as I'm a bit confused. I'm using an l-system (a recursive algorithm for generating branches). The trunk of the tree is the root node. It's orientation is aligned to the y axis. In the next iteration of the tree (e.g. the first branches), I might create a branch that is oriented say by +10 degrees in the X axis and a similar amount in the Z axis, relative to the trunk. I know that I should keep a rotation matrix at each branch, so that it can be applied to child branches, along with any modifications to the child branch. My questions then: for the trunk, the rotation matrix - is that just the identity matrix * initial orientation vector ? for the first branch (and subsequent branches) - I'll "inherit" the rotation matrix of the parent branch, and apply x and z rotations to that also. e.g. using glm::normalize; using glm::rotateX; using glm::vec4; using glm::mat4; using glm::rotate; vec4 vYAxis = vec4(0.0f, 1.0f, 0.0f, 0.0f); vec4 vInitial = normalize( rotateX( vYAxis, 10.0f ) ); mat4 mRotation = mat4(1.0); // trunk rotation matrix = identity * initial orientation vector mRotation *= vInitial; // first branch = parent rotation matrix * this branches rotations mRotation *= rotate( 10.0f, 1.0f, 0.0f, 0.0f ); // x rotation mRotation *= rotate( 10.0f, 0.0f, 0.0f, 1.0f ); // z rotation Are my maths and approach correct, or am I completely wrong? Finally, I'm using the glm library with OpenGL / C++ for this. Is the order of x rotation and z rotation important?

• Reacting to rectangle on rectangle collisions

  - by mcjohnalds45

  I don't know how to react to collisions between two axis aligned rectangles that have x, y, width and height values (x and y are from the centre of the box) to make them simply not overlap. I figured I'd just make them move away from each other depending on how far they intersect in the opposite direction (left, right, up or down) of where they collided. If I check for collisions only on the x axis or only on the y axis it works fine, but when checking for both collisions crazy stuff happens. This code executes when the first box collides with the second. It's in lua but feel free to answer in anything that isn't to too counter-intuitive. if box1.x < box2.x then box1.x = box1.x + box2.x - box1.x - (box1.width / 2) - (box2.width / 2) end if box1.x > box2.x then box1.x = box1.x - (box1.x - box2.x - (box1.width / 2) - (box2.width / 2)) end if box1.y < box2.y then box1.y = box1.y + box2.y - box1.y - (box1.height / 2) - (box2.height / 2) end if box1.y > box2.y then box1.y = box1.y - (box1.y - box2.y - (box1.height / 2) - (box2.height / 2)) end

• Calculating 3d rotation around random axis

  - by mitim

  This is actually a solved problem, but I want to understand why my original method didn't work (hoping someone with more knowledge can explain). (Keep in mind, I've not very experienced in 3d programming, having only played with the very basic for a little bit...nor do I have a lot of mathematical experience in this area). I wanted to animate a point rotating around another point at a random axis, say a 45 degrees along the y axis (think of an electron around a nucleus). I know how to rotate using the transform matrix along the X, Y and Z axis, but not an arbitrary (45 degree) axis. Eventually after some research I found a suggestion: Rotate the point by -45 degrees around the Z so that it is aligned. Then rotate by some increment along the Y axis, then rotate it back +45 degrees for every frame tick. While this certainly worked, I felt that it seemed to be more work then needed (too many method calls, math, etc) and would probably be pretty slow at runtime with many points to deal with. I thought maybe it was possible to combine all the rotation matrixes involve into 1 rotation matrix and use that as a single operation. Something like: [ cos(-45) -sin(-45) 0] [ sin(-45) cos(-45) 0] rotate by -45 along Z [ 0 0 1] multiply by [ cos(2) 0 -sin(2)] [ 0 1 0 ] rotate by 2 degrees (my increment) along Y [ sin(2) 0 cos(2)] then multiply that result by (in that order) [ cos(45) -sin(45) 0] [ sin(45) cos(45) 0] rotate by 45 along Z [ 0 0 1] I get 1 mess of a matrix of numbers (since I was working with unknowns and 2 angles), but I felt like it should work. It did not and I found a solution on wiki using a different matirx, but that is something else. I'm not sure if maybe I made an error in multiplying, but my question is: this is actually a viable way to solve the problem, to take all the separate transformations, combine them via multiplying, then use that or not?

• Managing constant buffers without FX interface

  - by xcrypt

  I am aware that there is a sample on working without FX in the samplebrowser, and I already checked that one. However, some questions arise: In the sample: D3DXMATRIXA16 mWorldViewProj; D3DXMATRIXA16 mWorld; D3DXMATRIXA16 mView; D3DXMATRIXA16 mProj; mWorld = g_World; mView = g_View; mProj = g_Projection; mWorldViewProj = mWorld * mView * mProj; VS_CONSTANT_BUFFER* pConstData; g_pConstantBuffer10->Map( D3D10_MAP_WRITE_DISCARD, NULL, ( void** )&pConstData ); pConstData->mWorldViewProj = mWorldViewProj; pConstData->fTime = fBoundedTime; g_pConstantBuffer10->Unmap(); They are copying their D3DXMATRIX'es to D3DXMATRIXA16. Checked on msdn, these new matrices are 16 byte aligned and optimised for intel pentium 4. So as my first question: 1) Is it necessary to copy matrices to D3DXMATRIXA16 before sending them to the constant buffer? And if no, why don't we just use D3DXMATRIXA16 all the time? I have another question about managing multiple constant buffers within one shader. Suppose that, within your shader, you have multiple constant buffers that need to be updated at different times: cbuffer cbNeverChanges { matrix View; }; cbuffer cbChangeOnResize { matrix Projection; }; cbuffer cbChangesEveryFrame { matrix World; float4 vMeshColor; }; Then how would I set these buffers all at different times? g_pd3dDevice->VSSetConstantBuffers( 0, 1, &g_pConstantBuffer10 ); gives me the possibility to set multiple buffers, but that is within one call. 2) Is that okay even if my constant buffers are updated at different times? And do I suppose I have to make sure the constantbuffers are in the same position in the array as the order they appear in the shader?

• Video on Hyperion Tax Provision

  - by Lia Nowodworska - Oracle

  ( in via Jan) EPM Information Development has asked us to remind you about the new video available for Hyperion Tax Provision. You can view it on the OracleEPMWebcasts YouTube channel here: http://bit.ly/1jxLlCy An information rich 4:40 minutes of your time.  So please take a look. The video gives a brief overview of the main features of  Hyperion Tax Provision. You will learn ... That Tax Provision and reporting System builds on the Hyperion Financial Close Reporting Platform That much of the Tax Provision flow process is similar to the Financial Close Process and that the modules have been aligned to work together very closely. That HTP enables you to integrate Book- and Tax Reporting on a common platform. That It uses the technology of HFM, ties in with SmartView and can be used with Hyperion Financial Reporting. That the native integration between the Financial System and the Tax System creates transparency for the Tax Departments and removes bottlenecks in the tax process. More technical information can be found here: Oracle Hyperion Tax Provision Data Sheet Oracle Hyperion Tax Provision White Paper Oracle Hyperion Tax Provision Documentation If you have another 45 minutes to spare and want to get into greater detail, then you can check out the recording of an Advisor Webcast that we did earlier last year: You can find this via KM Doc Oracle Business Analytics Advisor Webcast Schedule and Archive Recordings (Doc ID 1456233.1) -> Select the Tab "Archived 2013" and it is the third from the top: "Oracle Hyperion Tax Provision - Features and Overview with Demo" If you have questions towards that Advisor Webcast, you may participate in the Community Discussion about it.

• Strange behavior of RigidBody with gravity and impulse applied

  - by Heisenbug

  I'm doing some experiments trying to figure out how physics works in Unity. I created a cube mesh with a BoxCollider and a RigidBody. The cuve is laying on a mesh plane with a BoxCollider. I'm trying to update the object position applying a force on its RigidBody. Inside script FixedUpdate function I'm doing the following: public void FixedUpdate() { if (leftButtonPressed()) this.rigidbody.AddForce( this.transform.forward * this.forceStrength, ForceMode.Impulse); } Despite the object is aligned with the world axis and the force is applied along Z axis, it performs a quite big rotation movement around its y axis. Since I didn't modify the center of mass and the BoxCollider position and dimension, all values should be fine. Removing gravity and letting the object flying without touching the plane, the problem doesn't show. So I suppose it's related to the friction between objects, but I can't understand exactly which is the problem. Why this? What's my mistake? How can I fix this, or what's the right way to do such a moving an object on a plane through a force impulse?

The quick tutorials are aimed at showing the 'how to' of the basic capabilities to jump start use of XML dictionaries with the CAM Editor. The collection of dictionary tutorials videos run for a total of approximately 20 minutes.  Each video can be reviewed individually also. Learn how to use the dictionary functions to create dictionaries by harvesting data model components from existing XSD schema, SQL database table schema, or simple Excel / Open Office spreadsheets with tables of components listed.Also included are tips and functions relating to use of NIEM exchange development, IEPD and EIEM techniques.These videos should be viewed in conjunction with reviewing the overall concepts and techniques described in the companion video on the CAM Editor and Dictionaries overview.  The approach is aligned with OASIS and Core Components Technical Specification (CCTS) standards specifications for XML components and dictionaries.Dictionary collections can be stored locally on the file system, or local network, or collaboratively on the web or cloud deployment, or can be shared and managed securely using the Oracle Enterprise Repository (OER) tool. Also included are techniques relating to the use of the NIEM approach for developing XML exchange schema and IEPD packages.  This includes generating reuse scores, wantlist, and cross reference spreadsheets. Included in the latest release of the CAM Editor is the ability to use the analyse dictionary tool to determine duplicate components, conflicting component definitions, missing component descriptions and so on.  This ensures high quality dictionary component specifications.  Using the CAM Editor you can also create MindMap models and UML physical models of your dictionary components sets. For a complete guide to using the CAM Editor see the main YouTube video tutorials website and the CAM Editor website.

• Country specific content vs global content

  - by Ando

  I have a global product presentation website myproduct.com For certain countries I also own the country domain: myproduct.co.uk, myproduct.com.au, myproduct.es, myproduct.de, etc. The presentation website is translated in multiple languages and I set up redirects: myproduct.es will redirect to myproduct.com/es/, myproduct.de will redirect to myproduct.com/de/, etc. . The content so far is the same, just translated in different languages. The advantages are that it's easy to keep the content aligned - everything is managed from one centralized dashboard (I'm using Wordpress with qtranslate). Now I'm running into trouble as for different countries I want localized content - for UK I want to run different promotions and use a different reseller than for .com.au so I would like that users coming from myproduct.co.uk see something different than those coming from myproduct.com.au (and not be redirected to myproduct.com as they are right now). How can I achieve this? I could duplicate the whole main website and modify only certain parts but then I would have a lot of duplicate content (e.g. info about how the product works) and I would have pages that are likely to change (FAQ page) that I would have to keep updated over all websites. I can duplicate only partially the main website: on the localized website I would have only the pages that are different and then all other links would point to the .com site. This would solve the duplication problem but would cause confusion for the user as you would navigate from .co.uk to .com without noticing and then wonder how to get back. Other, better option?
