  • Mapping a 3D texture to a standard hollow-hull 3D model

    - by John
    I have 3D models which are typical hollow hulls. If such a model also had a 3D volumetric/voxel texture map then given a point P inside such a model, I'd like to be able to find its uvw coordinates within the 3D texture. Is this possible by simply setting 3D texcoords on my existing mesh or does it have to be broken up into polyhedra? Is there a way to map a 3D texture onto a mesh without doing this?

  • Ouya / Android : button mapping bitwise

    - by scorvi
    I am programming a game with the Gameplay3d Engine. But the Android site has no gamepad support and that is what I need to port my game to Ouya. So I implemented a simple gamepad support and it supports 2 gamepads. So my problem is that I put the button stats in a float array for every gamepad. But the Gameplay3d engine saves their stats in a unsigned int _buttons variable. It is set with bitwise operations and I have no clue how to translate my array to this.

  • Mapping local folder with an Ubuntu One folder

    - by Titus
    TrendMicro's Safesync has a nice feature, you can map your local folder to a folder in the cloud with a different name, e.g: PC1: C:\my_documents\pictures ===> office_pictures c:\my_documents\docs ===> office_docs PC2: C:\my_documents\pictures ===> private_pictures c:\my_documents\docs ===> private_docs Would this be possible with UbuntuOne? The reason is that I have multiple computers, and I don't want all my "my_documents" folders to sync across work and personal life...

  • Getting My Head Around Immutability

    - by Michael Mangold
    I'm new to object-oriented programming, and one concept that has been taking me a while to grasp is immutability. I think the light bulb went off last night but I want to verify: When I come across statements that an immutable object cannot be changed, I'm puzzled because I can, for instance, do the following: NSString *myName = @"Bob"; myName = @"Mike"; There, I just changed myName, of immutable type NSString. My problem is that the word, "object" can refer to the physical object in memory, or the abstraction, "myName." The former definition applies to the concept of immutability. As for the variable, a more clear (to me) definition of immutability is that the value of an immutable object can only be changed by also changing its location in memory, i.e. its reference (also known as its pointer). Is this correct, or am I still lost in the woods?

  • Mapping dynamic buffers in Direct3D11 in Windows Store apps

    - by Donnie
    I'm trying to make instanced geometry in Direct3D11, and the ID3D11DeviceContext1->Map() call is failing with the very helpful error of "Invalid Parameter" when I'm attempting to update the instance buffer. The buffer is declared as a member variable: Microsoft::WRL::ComPtr<ID3D11Buffer> m_instanceBuffer; Then I create it (which succeeds): D3D11_BUFFER_DESC instanceDesc; ZeroMemory(&instanceDesc, sizeof(D3D11_BUFFER_DESC)); instanceDesc.Usage = D3D11_USAGE_DYNAMIC; instanceDesc.ByteWidth = sizeof(InstanceData) * MAX_INSTANCE_COUNT; instanceDesc.BindFlags = D3D11_BIND_VERTEX_BUFFER; instanceDesc.CPUAccessFlags = D3D11_CPU_ACCESS_WRITE; instanceDesc.MiscFlags = 0; instanceDesc.StructureByteStride = 0; DX::ThrowIfFailed(d3dDevice->CreateBuffer(&instanceDesc, NULL, &m_instanceBuffer)); However, when I try to map it: D3D11_MAPPED_SUBRESOURCE inst; DX::ThrowIfFailed(d3dContext->Map(m_instanceBuffer.Get(), 0, D3D11_MAP_WRITE, 0, &inst)); The map call fails with E_INVALIDARG. Nothing is NULL incorrectly, and this being one of my first D3D apps I'm currently stumped on what to do next to track it down. I'm thinking I must be creating the buffer incorrectly, but I can't see how. Any input would be appreciated.

  • Mapping XFCE4/xRDP sessions to users

    - by garrilla
    I have Ubuntu 13.10 with Xubuntu Desktop - XFCE4. I'm trying to use XDRP to allow MS Windows users to login to the machine with their own user. I've been a lot around the houses with this! I've find two half-way solutions, but can't get them to work as I'd like... 1) in /etc/xrdp/xrdp.ini I set the port to -1 [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=-1 each time any user logs on they get a new session - they can never go back to their original session 2) in /etc/xrdp/xrdp.ini I set the port to 5912 (e.g) [xrdp1] name=sesman-Xvnc lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5912 each time any user logs on they always log on to the same session irrespective of their logon details ??) I found a mid-way solution, to create a lot of sessions by adding adding additional options in the xrdp.ini e.g. [xrdp8] name=Bob's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5913 [xrdp9] name=Jill's Logon lib=libvnc.so username=ask password=ask ip=127.0.0.1 port=5914 and so on, but he problem with this is that Jill can still log into Bob's remote session ??? Is it possible to to do what I'm trying to do? Maybe I have to use different tools?

  • Algorithm to reduce calls to mapping API

    - by aidan
    A random distribution of points lies on a map. This data lies behind an API, and I want to grab the complete set of points within a given bounding box. I can query the API with the bounding box and the API will return the set of points that fall within that box. The problem is that the API will limit the result set to 10 items, with no pagination and no indication if there are more points that have been omitted. So I made a recursive algorithm that takes a bounding box and requests the points that lie within it. If the result set is exactly 10 items, then I split the bounding box into four quadrants and recurse. It works fine but my question is this: if want to minimize the number of API calls, what is the optimal way to split the bounding box? Splitting it into quadrants was just an arbitrary decision. When there are a lot of points on the map, I have to drill down many levels before I start getting meaningful results. So I imagine it might be faster to split the box into, say, 9, 16, or more sections. But if I do that, then I eventually get to a point where a lot of requests are returning 0 results which isn't so efficient. Also, does the size of the limit on the results set affect the answer? (This is all assuming that I have no prior knowledge of nominal point density in the bounding box)

  • SEO Mapping, Tracking and Reporting

    Linking the pages of a website is done because search engines will be more aware of a site's presence when its pages are found at the other end of industry terms in anchor text contained with content at other locations. The total and quality of those links are factors that help promote rankings; when placed for SEO purposes they should be one-way links rather than reciprocal since reciprocal links are not any help in ranking brownie points and it is prohibitively time-consuming to administer a thousand of them. This is not to be confused with link exchanges; when you can...

  • CNAME cross subdomain mapping problem

    - by Ron Ranieri
    I have the exact same problem as this but I don't understand the solution. I have 2 different domain name(with different hosting/provider) domain-one.com and domain-two.com which I want sub.domain-one.com to point to sub.domain-two.com using CNAME. All have been setup and propagate correctly but now when I go to sub.domain-one.com it goes to basic page of the server. If I go directly to sub.domain-two.com the page load correctly. I've tried to add the subdomain using Addon Domains on cPanel but the problem persist.

  • Algorithm for rating books: Relative perception

    - by suneet
    So I am developing this application for rating books (think like IMDB for books) using relational database. Problem statement : Let's say book "A" deserves 8.5 in absolute sense. In case if A is the best book I have ever seen, I'll most probably rate it 9.5 whereas for someone else, it might be just an average book, so he/they will rate it less (say around 8). Let's assume 4 such guys rate it 8. If there are 10 guys who are like me (who haven't ever read great literature) and they all rate it 9.5-10. This will effectively make it's cumulative rating greater than 9 (9.5*10 + 8*4) / 14 = 9.1 whereas we needed the result to be 8.5 ... How can I take care of(normalize) this bias due to incorrect perception of individuals. MyProposedSolution : Here's one of the ways how I think it could be solved. We can have a variable Lit_coefficient which tells us how much knowledge a user has about literature. If I rate "A"(the book) 9.5 and person "X" rates it 8, then he must have read books much better than "A" and thus his Lit_coefficient should be higher. And then we can normalize the ratings according to the Lit_coefficient of user. Could there be a better algorithm/solution for the same?

  • Evoluent Vertical Mouse - Re-mapping Buttons?

    - by Paul
    I have the Evoluent Vertical Mouse at work and at home. One is wired, the other wireless. Ubuntu maps their buttons differently and it makes me crazy when I switch locations. I use 12.10, but same has applied to every Ubuntu version since 9.10. The wired mouse is as desired: top finger button is left-click, scroll wheel is middle click and scroll, middle finger button is a right-click. On the wireless version, bottom finger button is mapped to right-click and the middle finger button is center-click. I tried tinkering with these instructions, but wound up unable to boot to GUI... had to delete the .conf file to recover: http://denishaine.wordpress.com/2011/12/01/evoluent-mouse-with-ubuntu-11-04-and-11-10/ Help?

  • Mapping SEO Links by Navigable Internal Structure

    In order to give visibility to a new site, the SEO link building web master must follow the codes that give the site an indexed recognition on the Internet searching sites. This is both in terms of its back links and internal links. The accessibility too of the supporting websites linked to the parent site can be very effective in getting higher pings by the search engines.

  • How can I undo this key mapping?

    - by user273872
    First of all sorry my punctuation will be bad. its hard to type when keys are not doing what you expect. Eg it keeps scaring the **** out of me by taking a screen shot when I push the up arrow lolol So anyways, I broke a key on my keyboard and used xkeycaps to remap it to an unused key which worked. But then I realized it screwed up other keys... I think this is the program I used http://www.jwz.org/xkeycaps/man.html And then after doing the modifications I found out how to save them from the second answer in this question How to Map my enter key to a different key down where it says this "When you are happy with your current keymap and want to use it in future X-sessions, run the following command to save it: xmodmap -pke ~/.Xmodmap"

  • Countour Mapping API

    - by Crash
    I have done some searching on Google, but haven't come up with much as of yet. I am wanting to take a set of point data, which I had previously been using to create weighted points for a heat map through the Google API, and turn them into a contour map to overlay on the Google Maps API. I haven't seen anything in Google's code that would let me do this. Does anyone know of a good API to create such an overlay? Or is there possibly something I have overlooked that Google offers?

  • Image mapping using lookup tables [on hold]

    - by jblasius
    I have an optimization problem. I'm using a look-up table to map a pixel in an image: for (uint32_t index = 0u; index < imgSize; index++) { img[ lt[ index ] ] = val; } Is there a faster way to do this, perhaps using a reinterpret_cast or something like that? I am accessing two different memory addresses, so what is the compiler doing? One solution is to do a set of reads to access adjacent memory addresses. struct mblock { uint32_t buf[10u]; }; mblock mb; for (uint32_t index = 0u; index < imgSize; index += 10u) { mb = *reinterpret_cast<mblock*>(lt + index)); for (uint8_t i = 0u; i < 10u; i ++) { mb.buf[i] += img; } for (uint8_t i = 0u; i < 10u; i ++) { *( mb.buf[i] ) = val; } } This speeds up the code because I'm separating the image access from the table look-up; the positions in the look-up table are adjacent. I still get the image access problem as it is accessing random address positions.

  • Keeping the meshes "thickness" the same when scaling an object

    - by user1806687
    I've been bashing my head for the past couple of weeks trying to find a way to help me accomplish, on first look very easy task. So, I got this one object currently made out of 5 cuboids (2 sides, 1 top, 1 bottom, 1 back), this is just for an example, later on there will be whole range of different set ups. Now, the thing is when the user chooses to scale the whole object this is what should happen: X scale: top and bottom cuboids should get scaled by a scale factor, sides should get moved so they are positioned just like they were before(in this case at both ends of top and bottom cuboids), back should get scaled so it fits like before(if I simply scale it by a scale factor it will leave gaps on each side). Y scale: sides should get scaled by a scale factor, top and bottom cuboid should get moved, and back should also get scaled. Z scale: sides, top and bottom cuboids should get scaled, back should get moved. Hope you can help, EDIT: So, I've decided to explain the situation once more, this time more detailed(hopefully). I've also made some pictures of how the scaling should look like, where is the problem and the wrong way of scaling. I this example I will be using a thick walled box, with one face missing, where each wall is made by a cuboid(but later on there will be diffrent shapes of objects, where a one of the face might be roundish, or triangle or even under some angle), scaling will be 2x on X axis. 1.This is how the default object without any scaling applied looks like: http://img856.imageshack.us/img856/4293/defaulttz.png 2.If I scale the whole object(all of the meshes) by some scale factor, the problem becomes that the "thickness" of the object walls also change(which I do not want): http://img822.imageshack.us/img822/9073/wrongwaytoscale.png 3.This is how the correct scaling should look like. Appropriate faces gets caled in this case where the scale is on X axis(top, bottom, back): http://imageshack.us/photo/my-images/163/rightwayxscale1.png/ 4.But the scale factor might not be the same for all object all of the times. In this case the back has to get scaled a bit more or it leaves gaps: http://imageshack.us/photo/my-images/9/problemwhenscaling.png/ 5.If everything goes well this is how the final object should look like: http://imageshack.us/photo/my-images/856/rightwayxscale2.png/ So, as you have might noticed there are quite a bit of things to look out when scaling. I am asking you, if any of you have any idea on how to accomplish this scaling. I have tried whole bunch of things, from scaling all of the object by the same scale factor, to subtracting and adding sizes to get the right size. But nothing I tried worked, if one mesh got scaled correctly then others didnt. Donwload the example object. English is not my first language, so I am really sorry if its hard to understand what I am saying.

  • CentOS drive mapping? [on hold]

    - by DroidOS
    This is the first time I am posting on this particular StackExchange forum and I hope that I am using the right one for the present question. Briefly, this is what I need to do I am running a web service where users can, amongst other things, upload and store files on the server. What I want to do is to hive off user file storage to a different location so my server (CentOS 64 bit) can concentrate on what it does best - server side scripting and database management. As things stand all user files go into subdirectories in a folder called stash that lies above DOC_ROOT. What I would like to do is Transparently detect all attempts to read/write to stash/sub_folder and get/set file data on a remote server - ideally the latter would be one which replicates files like a CDN so they can be delivered from the closest/fastest location based on where the user's location. Even nicer would be if for all read accesses I could provide a URL that allows the user's browser to fetch the relevant file directly without having to funnel them via my server. I am a relative newbie when it comes to this sort of thing so I hope that I have phrased this question adequately well. From the little searching I done I gathered that WebDAV can be used to map drives to a different location on the web so perhaps that is a starting point. But if that will work I need to Establish how to get WebDAV up and running on my CentOS 64 bit server. Ideally, identify a service that allows this kind of file storage and provides an API I can use in my own scripting. I'd much appreciate any help with this.

  • Intuitive "Take Screenshot" key mapping used by games?

    - by Hatoru Hansou
    I recently had a problem testing my game on Linux Ubuntu. The Print key is intercepted by the desktop environment and It never reaches the game. Rather than fighting this, I will simply use any other key or key combination to trigger the screen capture functionality. Now, using the PRINT key is very intuitive because people already expect this behavior. What other keys are a good idea to use to take screenshots? And if possible elaborate why, have other apps/games used that key?

  • At what point does caching become necessary for a web application?

    - by Zaemz
    I'm considering the architecture for a web application. It's going to be a single page application that updates itself whenever the user selects different information on several forms that are available that are on the page. I was thinking that it shouldn't be good to rely on the user's browser to correctly interpret the information and update the view, so I'll send the user's choices to the server, and then get the data, send it back to the browser, and update the view. There's a table with 10,000 or so rows in a MySQL database that's going to be accessed pretty often, like once every 5-30 seconds for each user. I'm expecting 200-300 concurrent users at one time. I've read that a well designed relational database with simple queries are nothing for a RDBMS to handle, really, but I would still like to keep things quick for the client. Should this even be a concern for me at the moment? At what point would it be helpful to start using a separate caching service like Memcached or Redis, or would it even be necessary? I know that MySQL caches popular queries and the results, would this suffice?

  • What is the "Entity" reffering to in fluent Nhibernate Mapping Configuration?

    - by percent20
    I am trying to learn fluent nhibernate better so am doing a basic sample application from scratch, instead of using someone elses framework. However, I am finding I really don't understand what is going on in assigning mapping files. I have seen a lot of code examples which are all showing the same code, but nothing that spells it out. No description of how it works just that it works. Here is a code example that I see often. return Fluently.Configure() .Database(config) .Mappings(m => m.FluentMappings.AddFromAssemblyOf<Entity>()) .BuildSessionFactory(); So in the code example what is Entity? and how does that piece of code work? Part of me thinks it is the name of the assembly, but seeing as how the namespace I am using is usually the name of the assembly the compiler complains that I am using a namespace as a type. I feel this is important and am rather flustered by the fact I can't figure it out. Thanks

  • XP Client for NFS failure dialog on startup, but drive mapping works

    - by Matt Bennett
    I'm mounting an NFS share to some windows machines using the tools that come in the Services for UNIX Administration toolkit. I've set up the User Name Mapping service to use local passwd and group files. I had to manually start the User Name Mapping service, and then created an 'advanced map' from the XP machine's user to a uid that exists in on my NFS server, like so: Windows User: Matt Bennett UNIX Domain: PCNFS UNIX User: mattbennett UID: 10250 Primary: * I can map a network drive without any issues, and it correctly identifies the UID and GID to use, but when I reboot I get this message: "An error occurred while connecting to the NFS server. Make sure that the Client for NFS service has started. If the problem persists make sure Client for NFS service can communicate with User Name Mapping or PCNFS server." After dismissing the dialog, the machine finishes booting and the network drive is there in My Computer with the title "Disconnected Network Drive", but I can open it I can see the network share without a problem, and then it drops the 'disconnected' from its title. It seems like the services are starting in the wrong order or something, so the first attempt to connect fails but subsequent ones work as expected. There don't seem to be any symptoms apart from the dialog box, but obviously something's not quite right. What have I done wrong? Thanks, Matt.
