  • How to send multiple MVP matrices to a vertex shader in OpenGL ES 2.0

    - by Carbon Crystal
    I'm working my way through optimizing the rendering of sprites in a 2D game using OpenGL ES and I've hit the limit of my knowledge when it comes to GLSL and vertex shaders. I have two large float buffers containing my vertex coordinates and texture coordinates (eventually this will be one buffer) for multiple sprites in order to perform a single glDrawArrays call. This works but I've hit a snag when it comes to passing the transformation matrix into the vertex shader. My shader code is: uniform mat4 u_MVPMatrix; attribute vec4 a_Position; attribute vec2 a_TexCoordinate; varying vec2 v_TexCoordinate; void main() { v_TexCoordinate = a_TexCoordinate; gl_Position = u_MVPMatrix * a_Position; } In Java (Android) I am using a FloatBuffer to store the vertex/texture data and this is provided to the shader like so: mGlEs20.glVertexAttribPointer(mVertexHandle, Globals.GL_POSITION_VERTEX_COUNT, GLES20.GL_FLOAT, false, 0, mVertexCoordinates); mGlEs20.glVertexAttribPointer(mTextureCoordinateHandle, Globals.GL_TEXTURE_VERTEX_COUNT, GLES20.GL_FLOAT, false, 0, mTextureCoordinates); (The Globals.GL_POSITION_VERTEX_COUNT etc are just integers with the value of 2 right now) And I'm passing the MVP (Model/View/Projection) matrix buffer like this: GLES20.glUniformMatrix4fv(mMVPMatrixHandle, 1, false, mModelCoordinates); (mModelCoordinates is a FloatBuffer containing 16-float sequences representing the MVP matrix for each sprite) This renders my scene but all the sprites share the same transformation, so it's obviously only picking the first 16 elements from the buffer which makes sense since I am passing in "1" as the second parameter. The documentation for this method says: "This should be 1 if the targeted uniform variable is not an array of matrices, and 1 or more if it is an array of matrices." So I tried modifying the shader with a fixed size array large enough to accomodate most of my scenarios: uniform mat4 u_MVPMatrix[1000]; But this lead to an error in the shader: cannot convert from 'uniform array of 4X4 matrix of float' to 'Position 4-component vector of float' This just seems wrong anyway as it's not clear to me how the shader would know when to transition to the next matrix anyway. Anyone have an idea how I can get my shader to pick up a different MVP matrix (i.e. the NEXT 16 floats) from my MVP buffer for every 4 vertices it encounters? (I am using GL_TRIANGLE_STRIP so each sprite has 4 vertices). Thanks!

  • MS Excel automation without macros in the generated reports. Any thoughts?

    - by ezeki77
    Hello! I know that the web is full of questions like this one, but I still haven't been able to apply the answers I can find to my situation. I realize there is VBA, but I always disliked having the program/macro living inside the Excel file, with the resulting bloat, security warnings, etc. I'm thinking along the lines of a VBScript that works on a set of Excel files while leaving them macro-free. Now, I've been able to "paint the first column blue" for all files in a directory following this approach, but I need to do more complex operations (charts, pivot tables, etc.), which would be much harder (impossible?) with VBScript than with VBA. For this specific example knowing how to remove all macros from all files after processing would be enough, but all suggestions are welcome. Any good references? Any advice on how to best approach external batch processing of Excel files will be appreciated. Thanks! PS: I eagerly tried Mark Hammond's great PyWin32 package, but the lack of documentation and interpreter feedback discouraged me.

  • How to interpret situations where Math.Acos() reports invalid input?

    - by Sean Ochoa
    Hey all. I'm computing the angle between two vectors, and sometimes Math.Acos() returns NaN when it's input is out of bounds (-1 input && input 1) for a cosine. What does that mean, exactly? Would someone be able to explain what's happening? Any help is appreciated! Here's me method: public double AngleBetween(vector b) { var dotProd = this.Dot(b); var lenProd = this.Len*b.Len; var divOperation = dotProd/lenProd; // http://msdn.microsoft.com/en-us/library/system.math.acos.aspx return Math.Acos(divOperation) * (180.0 / Math.PI); }

  • Hudson's FindBugs plugin reports line number "-1" for bugs. Ideas?

    - by John B.
    Greetings, I have a simple test project set up in Hudson and the project's build process (a batch file) generates a findbugs.xml file. This is processed by Hudson's FindBugs plugin but it shows the line number of the bugs as "-1" instead of their actual line number. A coworker suggested I enable debug info for the compiler. I used the -g "Generate all debugging info" option for javac but nothing seemed to change. My build command is: javac -g -classpath C:\testWebApp1\src -d C:\testWebApp1\build C:\testWebApp1\src\*.java The only other thing in the build.bat file is a call to the FindBug tool (text UI). Here is what the FindBugs Plugin says about the first bug: File: GenerateHellos.java, Line: -1, Type: UUF_UNUSED_FIELD, Priority: Normal, Category: PERFORMANCE Any ideas? Thanks a ton!

  • Can't call an object method. PHP reports variable undefined

    - by user1285697
    This is the weirdest bug! It is probably something silly, but I have no idea how to fix it. If anyone could help, I would be most grateful! I have three files, one is called items.php, another is called tableFunctions.php, and the third is called mysql.php. I use two global objects called 'mysql' and 'tableFunctions'. They are stored in the files 'mysql.php', and 'tableFunctions.php', respectively. In each file, I create an instance of its object, assigning it to the global variable $_mysql, or $_table. like this: In the file mysql.php: global $_mysql; $_mysql = new mysql(); In the file tableFunctions.php: global $_table; $_table = new tableFunctions(); Here's how it is supposed to work: The items.php file includes the tableFunctions.php file... Which in turn, needs the mysql.php file, so it includes it too. In the items.php file, I call the method getTable(), which is contained in the object tableFunctions.(and in the variable $_table.) Like this: $t = $_table->getTable('items'); The getTable function calls the method, arrayFromResult(), which is contained within in the object mysql.(and in the variable $_mysql.) Like this: $result = $_mysql->arrayFromResult($r); That's where I get the error. PHP says that the variable '$_mysql' is undefined, but I defined it in the 'mysql.php' file.(see above) I also included mysql.php with the following code: include_once 'mysql.php'; I have no idea what is wrong! If anyone can help that would be much appreciated. The source files can be downloaded with the following link: https://www.dropbox.com/sh/bjj2gyjsybym89r/YLxqyNvQdn

  • How can I only have a single move command in a batch file?

    - by PeanutsMonkey
    I have an existing batch file that attempts to move files from 2 directories to 2 different locations. At the moment these are called as 2 separate move commands. I am wanting to simply the code further and was wondering if there was a way to do so @echo off for %%a in (C:\Test\*.*) do if "%%~xa" == "" move /Y "C:\Test\%%~na%%~xa" "D:\Done" for %%i in (C:\Sample\*.*) do if "%%~xi" == "" move /Y "C:\Sample\%%~ni%%~xi" "D:\Done"

  • SciPy interp1d results are different than MatLab interp1

    - by LMO
    I'm converting a MatLab program to Python, and I'm having problems understanding why scipy.interpolate.interp1d is giving different results than MatLab interp1. In MatLab the usage is slightly different: yi = interp1(x,Y,xi,'cubic') SciPy: f = interp1d(x,Y,kind='cubic') yi = f(xi) For a trivial example the results are the same: MatLab: interp1([0 1 2 3 4], [0 1 2 3 4],[1.5 2.5 3.5],'cubic') 1.5000 2.5000 3.5000 Python: interp1d([1,2,3,4],[1,2,3,4],kind='cubic')([1.5,2.5,3.5]) array([ 1.5, 2.5, 3.5]) But for a real-world example they are not the same: x = 0.0000e+000 2.1333e+001 3.2000e+001 1.6000e+004 2.1333e+004 2.3994e+004 Y = -6 -6 20 20 -6 -6 xi = 0.00000 11.72161 23.44322 35.16484... (2048 data points) Matlab: -6.0000e+000 -1.2330e+001 -3.7384e+000 ... 7.0235e+000 7.0028e+000 6.9821e+000 SciPy: array([[ -6.00000000e+00], [ -1.56304101e+01], [ -2.04908267e+00], ..., [ 1.64475576e+05], [ 8.28360759e+04], [ -5.99999999e+00]]) Any thoughts as to how to can get results that are consistent with MatLab?

  • Programmatically Insert Page Break in Active Report

    - by Kevin Babcock
    I've been scouring the web for a good example, but cannot figure out how to add a page break to an Active Reports report programmatically. The reports I'm working with usually require 1-2 pages for each record. In order to support dual-sided printing of the reports I want to insert a blank page for each record that uses an odd number of pages, ensuring that each new record is printed on the front of each printed page. I'm very new to Active Reports, so any suggestions, code samples, or links are much appreciated!

  • Reporting Services 2005 Model using WCF Service for data

    - by Stu
    I am trying to use WCF Services as models for SQL Server Reporting Services 2005 reports. I can do this if I design the reports in the designer but cannot do it for a Reporting Model project which I think I need to make reports in the Report Builder. My full requirement is to have a report builder that the users can use building reports based on DTOs supplied from my WCF service. Thanks

  • Can spliting an access database cause printer and reporting issues?

    - by leeand00
    We have a setup in which our users log into an access database using MS Access 2003 over an RDP connection. The user's login to their own machines first using a roaming profile. They then click an rdp connection file on the desktop and login to the remote server, via RDP, where they use MS Access as the shell; they don't have any access to any of explorer.exe features such as the start menu. The database they are logging into is more of an application, and provides functionality for entering data, querying data, and running reports via form based menus. It all worked pretty well until we split the database as it was nearing 2GBs in size. We moved out the payroll data into a separate partition, a database with the same name in a different folder, both of them on the server. Only two tables were moved into this new database partition, and they were re-linked as external tables in the new partition. Now while everything appears to be working fine data-wise after the split, there's a new issue when our users login via RDP and attempt to run reports: often the report will not display and instead the user sees an error about the click event of the form. At first I didn't even know it was printer-related, as we didn't really change anything related to the printers as far as I knew. Confused about the error, I talked to the guy who previously worked here and who was in charge of splitting the database, and he told me to tell the users to set their default printers (on their local machines, not on the server) to the "printer" Microsoft XPS Document Writer which isn't a physical printer at all. This allowed the user's to display their reports, but if they want to print out reports, they are required to go to the File menu and select Print, clicking the print icon on the toolbar takes them to a Save As... dialog as would be expected when using the Microsoft XPS Document Writer as your default printer. It's easy to tell if the user is having a problem because a quick mouseover of the printer icon will yield a tooltip of (none) when they cannot access their reports, and a tooltip of Microsoft XPS Document Writer when they can view the reports. If the user's printer is set to anything other than Microsoft XPS Document Writer as the default on their local machine, then (none) is always displayed when they rdp to the database. The RDP settings are setup to transfer the local printer to the server. Telling the users to do this to print has been more of a band-aid on the whole situation until we find a better solution and an explanation as to why splitting a database would prevent users from printing or even viewing access database reports. Which is why I'm here asking this question. Also of note all the printers on the network now show up on the server so that when the users do click File->Print to print their reports on a physical printer, they have to look through a huge list of printers to find theirs in the dropdown. So the little band-aid fix we have is not ideal. Previously, only the printers on the user's local machine displayed here, and not all the printers on the network. My co-worker seems to think this has something to do with permissions, I personally think it has to do with roaming profiles, and Group Policies which is what I've been reading up on. I really don't know how to fix this or how it is related to splitting the database.

  • A report writer for non-programmers?

    - by Earlz
    Hello, we are wanting for users to be able to write their own reports in our application. It is a web application. We don't care if they must download an application in order to create reports, but we need for them to be able to print off reports from the web in PDF format or similar. The report writer is to be used by non-programmers, or at best very light programmers(like the ones that make VBA macros and such). (the writer is not a core part of the program though. So if there is a learning curve, then that is acceptable to a certain extent) We were looking at Crystal Reports but it seems like it'll cost $7000 which is just way too much for right now(though our system is very flexible so could support it eventually). We are also looking at Fast Reports which seems pretty promising, but I'm not sure the report writer would be easy for non-programmers to grasp. Can someone recommend a good report writer for non programmers that won't break the bank?

  • Access Services in SharePoint Server 2010

    - by Wayne
    Another SharePoint Server 2010 feature which cannot go unnoticed is the Access Services. Access Services is a service in SharePoint Server 2010 that allows administrators to view, edit, and configure a Microsoft access application within a Web Browser. Access Services settings support backup and recovery, regardless of whether there is a UI setting in Central Administration. However, backup and recovery only apply to service-level and administrative-level settings; end-user content from the Access application is not backed up as part of this process. Access Services has Windows PowerShell functionality that can be used to provide the service that uses settings from a previous backup; configure and manage macro and query setting; manage and configure session management; and configure all the global settings of the service. Key Benefits of SharePoint Server Access Services Easier Access to right tools: The enhanced, customizable Ribbon in Access 2010 makes it easy to uncover more commands so you can focus on the end product. The new Microsoft Office BackstageTM view is yet another feature that can help you easily analyze and document your database, share, publish, and customize your Access 2010 experience, all from one convenient location. Helps build database effortlessly and quickly: Out-of-the box templates and reusable components make Access Services the fastest, simplest database solution available. It helps find new pre-built templates which you can start using without customization or select templates created by your peers in the Access online community and customize them to meet your needs. It builds your databases with new modular components. New Application Parts enable you to add a set of common Access components, such as a table and form for task management, to your database in a few simple clicks. Database navigation is now simplified. It creates Navigation Forms and makes your frequently used forms and reports more accessible without writing any code or logic. Create Impactful forms and reports: Whether it's an inventory of your assets or customer sales database, Access 2010 brings the innovative tools you'd expect from Microsoft Office. Access Services easily spot trends and add emphasis to your data. It quickly create coordinating database forms and reports and bring the Web into your database. Obtain a centralized landing pad for your data: Access 2010 offers easy ways to bring your data together and help increase work quality. New technologies help break down barriers so you can share and work together on your databases, making you or your team more efficient and productive. Add automation and complex expressions: If you need a more robust database design, such as preventing record deletion if a specific condition is met or if you need to create calculations to forecast your budget, Access 2010 empowers you to be your own developer. The enhanced Expression Builder greatly simplifies your expression building experience with IntelliSense®. With the revamped Macro Designer, it's now even easier for you to add basic logic to your database. New Data Macros allow you to attach logic to your data, centralizing the logic on the table, not the objects that update your data. Key features of Access Services 2010 - Access database content through a Web browser: Newly added Access Services on Microsoft SharePoint Server 2010 enables you to make your databases available on the Web with new Web databases. Users without an Access client can open Web forms and reports via a browser and changes are automatically synchronized. - Simplify how you access the features you need: The Ribbon, improved in Access 2010, helps you access commands even more quickly by enabling you to customize or create your own tabs. The new Microsoft Office Backstage view replaces the traditional File menu to provide one central, organized location for all of your document management tasks. - Codeless navigation: Use professional looking web-like navigation forms to make frequently used forms and reports more accessible without writing any code or logic. - Easily reuse Access items in other databases: Use Application Parts to add pre-built Access components for common tasks to your database in a few simple clicks. You can also package common database components, such as data entry forms and reports for task management, and reuse them across your organization or other databases. - Simplified formatting: By using Office themes you can create coordinating professional forms and reports across your database. Simply select a familiar and great looking Office theme, or design your own, and apply it to your database. Newly created Access objects will automatically match your chosen theme.

  • What is a good reporting service for a simple database/hobbyist setup?

    - by Zombies
    I have a meager production environment running on my PC for a little application that I work on in my spare time. At this point I have the basics setup, MySQL, junit, svn... I am midway through development and I now need to generate various reports. These reports are based on what data is in the database.... Now, my question is this: Is there an existing reporting tool that accepts SQL and generates various reports (via: email, PDF, etc). Some tool which makes writing new reports easy, while also having a somewhat robust set of features. Does this software exist or must I write all of these reports myself?

  • Find the element with the most "neighbors" in a sequence

    - by Bao An
    Assume that we have a sequence S with n elements <x1,x2,...,xn>. A pair of elements xi,xj are considered neighbors if |xi-xj|<d, with d a given distance between two neighbors. So how can find out the element that has most neighbors in the sequence? (A simply way is sorting the sequence and then calculating number of each element but it's time complexity is quite large): O(nlogn) May you please help me find a better way to reduce time complexity?

I have an application deployed in a subdomain, a .htaccess with a handler like this: # Define the FastCGI Mono launcher as an Apache handler and let # it manage this web-application (its files and subdirectories) SetHandler monoWrapper Action monoWrapper /home/arienh4/<domain>/cgi-bin/mono.fcgi virtual My mono.fcgi is set up as such: #!/bin/sh #umask 0077 exec >>/home/arienh4/tmp/mono-fcgi.log exec 2>>/home/arienh4/tmp/mono-fcgi.err echo $(date +"[%F %T]") Starting fastcgi-mono-server2 cd / chmod 0700 /home/arienh4/tmp/mono-fcgi.sock echo $$>/home/arienh4/tmp/mono-fcgi.pid # stdin is the socket handle export PATH="/home/arienh4/mono/bin:$PATH" export LD_LIBRARY_PATH="/home/arienh4/mono/lib:$LD_LIBRARY_PATH" export TMP="/home/arienh4/tmp" export MONO_SHARED_DIR="/home/arienh4/tmp" exec /home/arienh4/mono/bin/mono /home/arienh4/mono/lib/mono/2.0/fastcgi-mono-server2.exe \ /logfile=/home/arienh4/logs/fastcgi-mono-web.log /loglevels=All \ /applications=/:/home/arienh4/<domain> I took this from the Mono site for CGI, I'm not sure if I'm doing it correctly though. This code is resulting in this error: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace. I have no idea what's causing this. As far as I can see, Mono isn't even hit (no log files are created).
