  • Brand New Annotations Support

    - by Ondrej Brejla
    Hi all! Today we would like to introduce you our brand new annotation support for NetBeans 7.2. The first thing which is different is the look of annotations in code completion. As you can see, there is a new annotation icon and an annotation type. Because we have a lot of modules with their own annotations, we differ them in code completion window by their type. We support annotations for: ApiGen (legacy PHPDoc annotations), PHPUnit, Doctrine 2 (ORM and ODM) and Symfony 2. Every annotation can be associated with some context. We recognize four of them: function, class/interface (type), method and field. It means that you will get just proper annotations for your class field as well as your global function. Do you have your own annotations? Or do you simply miss some? There is nothing hard to add it in there. We have a simple UI for adding your custom annotations! It's in Tools -> Options -> PHP -> Annotations. Here you can simply add, edit or delete your annotations. When you try to create new one, all fields are prefilled by some default values. So you really don't have to remember "how to use that crazy freemarker syntax". If you are satisfied with your new annotation, you can see it in a code completion window among other annotations. As you can see it has its own "Custom" type. That's all for today and as usual, please test it and if you find something strange, don't hesitate to file a new issue (component php, subcomponent Editor). Thanks.

  • Separate php.ini file for each Apache virtual host?

    - by Calvin L
    Is it possible to have a separate php.ini file that overrides the default php.ini file for each virtual host? I'm running Apache/2.2.14, PHP 5.3.2-1. For example I have several vhosts pointing to domains in my /var/www/ directory: /var/www/website1.com /var/www/website2.com What I'd like is to be able to place a custom php.ini file in each directory that would override the default values only for that vhost, but keep the original defaults if the value isn't specified: /var/www/website1.com/htdocs/ /var/www/website1.com/php.ini EDIT: I found more info on the topic here for those interested: http://serverfault.com/questions/34078/how-do-i-set-up-per-site-php-ini-files-on-a-lamp-server-using-namevirtualhosts

  • Is aspect oriented programming a misnomer?

    - by glenviewjeff
    From everything I have learned about "Aspect Oriented Programming" or "Aspect Oriented Software Development," labeling it as a programming paradigm or methodology appears to be inaccurate. From what I can tell it is not a fundamental technique for programming. To nail down what is meant by "paradigm" and "methodology," please refer to the following definitions from the American Heritage Dictionary. Compare how well or poorly "Object-Oriented Programming" applies to each vs. how well AOP fits. Paradigm: A set of assumptions, concepts, values, and practices that constitutes a way of viewing reality for the community that shares them, especially in an intellectual discipline. Methodology: A body of practices, procedures, and rules used by those who work in a discipline or engage in an inquiry; a set of working methods. "Evidence-based medicine" satisfies the definition of paradigm, but "hysterectomy-based medicine" would be a misnomer because the problem space is too narrow. I am getting the impression that AOP may be misnamed because based on the "oriented-programming" suffix, AOP is alleging to be both a paradigm and a methodology in the same way "Object-Oriented Programming" is. Both of these terms (paradigm and methodology) indicate a fundamental technique, where what I understand about aspects is a technology for solving a narrow problem scope, maybe comparable in magnitude to the static variable feature of Java. If it's true that aspects solve a narrow set of problems, and AOP isn't a misnomer, then why shouldn't all programming techniques be given the "oriented-programming" suffix, such as "inheritance-oriented programming," "dependency-oriented programming," or "scope-oriented programming?"

  • IIS7 FastCGI downloads quit at 4128760 bytes on slow connections

    - by eingko
    I'm using FastCGI via IIS7 to host a PHP application. For whatever reason downloads that are streamed via PHP (i.e. a script that outputs a file/bytes as a response) download perfectly fine on high-speed connections but on anything slower (even on DSL) quits at EXACTLY 4128760 bytes (~3.9MB) - which makes me think it's a configuration issue... We only started having this problem when we switched from Apache to IIS - this also points to a configuration problem, I think. But if it's a configuration issue, why would it only affect slower connections? Does anyone know where (or how) I could possibly change a setting like this? I've tried changing the idleTimeout, executionTimeout, and activityTimeout values in my web.config but this hasn't helped at all. Any help or direction would be greatly appreciated. Thanks in advance.

  • Unity3d: calculate the result of a transform without modifying transform object itself

    - by Heisenbug
    I'm in the following situation: I need to move an object in some way, basically rotating it around its parent local position, or translating it in its parent local space (I know how to do this). The amount of rotation and translation is know at runtime (it depends on several factors, the speed of the object, enviroment factors, etc..). The problem is the following: I can perform this transformation only if the result position of the transformed object fit some criterias. An example could be this: the distance between the position before and after the transformation must be less than a given threshold. (Actually the conditions could be several and more complex) The problem is that if I use Transform.Rotate and Transform.Translate methods of my GameObject, I will loose the original Transform values. I think I can't copy the original Transform using instantiate for performance issues. How can I perform such a task? I think I have more or less 2 possibilities: First Don't modify the GameObject position through Transform. Calculate which will be the position after the transform. If the position is legal, modify transform through Translate and Rotate methods Second Store the original transform someway. Transform the object using Translate and Rotate. If the transformed position is illegal, restore the original one.

  • Excel - Referring to a certain cell based off of data in another

    - by Ethan Brouwer
    I have a spreadsheet where there is one table with the headings: Coordinate, Lat, Long Another with headings Triangle, Coordinate 1, Coordinate 2, Coordinate 3, Area What this is for, is taking the triangles formed by the specified three coordinates' area based off of Girard's theorem, as they are all spherical triangles. I need to take the specific latitude and longitude values from the first table based on the coordinate numbers underneath the three coordinate headings in the second table. I hope this makes sense. Here are pictures detailing what the two tables look like: Table 1 Table 2 Thanks in advance. And I really do hope this makes sense.

  • Term for unit testing that separates test logic from test result data

    - by mario
    So I'm not doing any unit testing. But I've had an idea to make it more appropriate for my field of use. Yet it's not clear if something like this exists, and if, how it would possibly be called. Ordinary unit tests combine the test logic and the expected outcome. In essence the testing framework only checks for booleans (did this match, did the expected result result). To generalize, the test code itself references the audited functions, and also explicites the result values like so: unit::assert( test_me() == 17 ) What I'm looking for is a separation of concerns. The test itself should only contain the tested logic. The outcome and result data should be handled by the unit testing or assertion framework. As example: unit::probe( test_me() ) Here the probe actually doubles as collector in the first run, and afterwards as verification method. The expected 17 is not mentioned in the test code, but stored or managed elsewhere. How is this scheme called? Or how would you call it? I hope I can find some actual implementations with the proper terminology. Obviously such a pattern is unfit for TDD. It's strictly for regression testing. Also obviously, it cannot be used for all cases. Only the simpler test subjects can be analyzed that way, for anything else the ordinary unit test setup and assertion steps are required. And yes, this could be manually accomplished by crafting a ResultWhateverObject, but that would still require hardwiring that to the test logic. Also keep in mind that I'm inquiring for use with scripting languages, and not about Java. I'm aware that the xUnit pattern originates there, and why it's hence as elaborate as it is. Btw, I've discovered one test execution framework which allows for shortening simple test notations to: test_me(); // 17 While thus the result data is no longer coded in (it's a comment), that's still not a complete separation and of course would work only for scalar results.

  • Memcached failover

    - by user25164
    We have 2 memcached servers configured and use the Eniym client. When one of the server is down, it appears this server is added to the deadServers list (ServerPool.cs) and tries to resurrect the server every 10seconds (we have configured deadTimeOut to be 10seconds). Attempting to connect to the failed server causes a TCP timeout, the pages take a long time to load which results in bad user experience. 1) What is the standard way of resolving this issue? There are some posts about removing the server from the deadServers list. Is it okay to do this? 2) What is the recommended deadTimeOut setting (I understand by default it's 2 mins and we've changed it to 10seconds in our implementation) 3) Am I correct in my understanding that the cached data is not replicated across Server 1 and Server 2? If Server 1 is down, then it goes to the database to fetch these values (and it doesn't really check Server2)? Any help is really appreciated.

  • WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256

    - by user702295
    WARNING Retrying Bulk Insert for file:sqlldr due to Communication Error:256 I am running my engine on Linux and am receiving an intermittent message "WARNING Retrying bulk insert for file: sqlldr due to communication Error: 256" The engine seems to have completed successfully, but it is not clear if this error caused some of the forecast to not complete. It is also not clear what caused the error. Generally if you see only the WARNING of it, it means that next retries of the same load request have eventually succeeded and so the run a a whole is not affected. In order to know more about what happens, look for .log/.bad files left in the engines bin directory or possibly a quote of them within the specific engine log that had the issue.  The sqlnet.log file may also have some information about it and perhaps at the database server side there may be some log/alert regarding what happened.  Look at the alert.log. In general it could be that the database server/network was over loaded at the time and somehow the connection was rejected/failed/aborted either due to specific setting on concurrent connections/sessions or inadvertently due to glitch in network/os/hardware. If this repeats and becomes more frequent during the run you should look further into it as mentioned above. You can also track this using either SQL*Trace or java.util.logging.  - Globally enable logging by setting the oracle.jdbc.Trace system property java -Doracle.jdbc.Trace=true - Client Side Tracing: Your SQLNET.ORA file should contain the following lines to produce a client side trace file: trace_level_client = 10 trace_unique_client = on trace_file_client = sqlnet.trc trace_directory_client = <path_to_trace_dir> Server Side Tracing: To enable server side tracing, use the following parameters: trace_level_server = 10 trace_file_server = server.trc trace_directory_server = <path_to_trace_dir> Tracing Levels: The following values can be used for TRACE_LEVEL* parameters:     16 or SUPPORT — WorldWide Customer Support trace information     10 or ADMIN — Administration trace information     4 or USER — User trace information     0 or OFF — no tracing, the default Additional information is readily available via the web.

  • Is paper indispensable in a programmer's everyday work?

    - by rwong
    As a programmer who work in a company whose vision is to make paperless office possible, is there any way I can work effectively while using less paper? I can list at least several kinds of papers I use quite often: Paper notebook, on which I do most of the pre-coding design work and ideas Books Temporary printouts of source code, though not so often (in color, with a 6 point font at 600 DPI) Sticky note, to remind myself of things that should be taken care of within a few days On the other hand, I also use a wiki and an office text editor. Once a while I would use a diagramming software to make a few flowcharts. Deeper questions: Is there a relationship between paper use and productivity? How can programmers help save the trees? Is paperless software development fundamentally different from paperless office? Related questions: Do you ever write code with pen and paper, and should we do it more often? What physical tools do you find useful to work as a programmer? What things are essential on a programmer's desk? Stuff every programmer needs while working Additional info, if it helps: Everyone has dual monitors. We have decent project management and issue tracking software (both web-based). Please be constructive. In particular, please give your answer to your peer programmers who wish to be flexible and are willing to change working style in order to become more productive as well as meeting certain their own personal values. Edited: I removed the company's view because it appears to be too flamebait. If you need to see my original words, go to the edit history. Deleted: Doxygen and whiteboard. Reason: disregarding my personal experience with these great tools, we never had to print out anything as a consequence of using/not using them. To see my original words, go to the edit history.

  • My browsers won't use my full screen resolution, IE different

    - by curtis
    My screen resolution is actually 3200x1800, but when I'm in a browser it acts like I have a smaller resolution. How do I get my browsers to use my full resolution? On Chrome it's using 1280x720, and on IE it's using 1600x900. According to whatismyscreenresolution.com, which is showing different values for different browsers. I took a screenshot of them and verified that my resolution is 3200x1800 as that is the pixels in the bitmap. I'm on a laptop with no monitor plugged in. My zoom in both browsers is at 100%. I've tried zooming out below 100% but then the text is unreadable and pixellated. I've tried restarting. Windows 8.1. I've tried the chrome extension OptiZoom and it does nothing. document.body.clientWidth gives 1247, and I want it to give 3200.

  • Is this method pure?

    - by Thomas Levesque
    I have the following extension method: public static IEnumerable<T> Apply<T>( [NotNull] this IEnumerable<T> source, [NotNull] Action<T> action) where T : class { source.CheckArgumentNull("source"); action.CheckArgumentNull("action"); return source.ApplyIterator(action); } private static IEnumerable<T> ApplyIterator<T>(this IEnumerable<T> source, Action<T> action) where T : class { foreach (var item in source) { action(item); yield return item; } } It just applies an action to each item of the sequence before returning it. I was wondering if I should apply the Pure attribute (from Resharper annotations) to this method, and I can see arguments for and against it. Pros: strictly speaking, it is pure; just calling it on a sequence doesn't alter the sequence (it returns a new sequence) or make any observable state change calling it without using the result is clearly a mistake, since it has no effect unless the sequence is enumerated, so I'd like Resharper to warn me if I do that. Cons: even though the Apply method itself is pure, enumerating the resulting sequence will make observable state changes (which is the point of the method). For instance, items.Apply(i => i.Count++) will change the values of the items every time it's enumerated. So applying the Pure attribute is probably misleading... What do you think? Should I apply the attribute or not?

  • Two different domains as one user session

    - by Mathew Foscarini
    I have two websites that are run as the same service. Each domain offers articles from a different market. At the top of each page the two domains are shown as menu options. If a user clicks one they can switch to the other domain. See here: http://www.cgtag.com Each domain has a different Google Analytics account, and when a user switches domains Google is counting this as a new session. It's listing the other domain as the "referral" for that new session. When the user switches back to the first domain Google is counting this as a returning visitor. This is messing up my reports. Showing returning visitors values that are higher than reality. It's also increasing hits on landing pages when the user switches, and listing the other domain as a referral site. I've found tips on how to list two domains as one website, but that results in merging the data. I want to keep the two domains separate so that I can track each ones performance, but I don't want to count domain changes as new sessions. Maybe something like treating the two domains as subdomains.

  • Grid-Based 2D Lighting Problems

    - by Lemoncreme
    I am aware this question has been asked before, but unfortunately I am new to the language, so the complicated explanations I've found do not help me in the least. I need a lighting engine for my game, and I've tried some procedural lighting systems. This method works the best: if (light[xx - 1, yy] > light[xx, yy]) light[xx, yy] = light[xx - 1, yy] - lightPass; if (light[xx, yy - 1] > light[xx, yy]) light[xx, yy] = light[xx, yy - 1] - lightPass; if (light[xx + 1, yy] > light[xx, yy]) light[xx, yy] = light[xx + 1, yy] - lightPass; if (light[xx, yy + 1] > light[xx, yy]) light[xx, yy] = light[xx, yy + 1] - lightPass; (Subtracts adjacent values by 'lightPass' variable if they are more bright) (It's in a for() loop) This is all fine and dandy except for a an obvious reason: The system favors whatever comes first in the for() loop This is what the above code looks like applied to my game: If I could get some help on creating a new procedural or otherwise lighting system I would really appreciate it!

  • need for tcp fine-tuning on heavily used proxy server

    - by Vijay Gharge
    Hi all, I am using squid like Internet proxy server on RHEL 4 update 6 & 8 with quite heavy load i.e. 8k established connections during peak hour. Without depending much on application provider's expertise I want to achieve maximum o/p from linux. W.r.t. that I have certain questions as following: How to find out if there is scope for further tcp fine-tuning (without exhausting available resources) as the benchmark values given by vendor looks poor! Is there any parameter value that is available from OS / network stack that will show me the results. If at all there is scope, how shall I identify & configure OS tcp stack parameters i.e. using sysctl or any specific parameter Post tuning how shall I clearly measure performance enhancement / degradation ?

    I am stumped, and was hoping someone here would have a quick and easy answer. I did a fresh install of MySQL 5.5 and am trying to pass parameters into a stored procedure. The parameter values aren't being read by the stored procedure. MySQL doesn't throw an error and processes the code with null parameters. Here is the code: DELIMITER $$ CREATE DEFINER=`root`@`%` PROCEDURE `testing`(IN parameter INTEGER) BEGIN UPDATE table_name SET valueToChange = 'Test' WHERE mainID = @parameter; END And here is the query I'm using to call it: USE database_name; CALL testing(72); Can anyone help?

  • Changing frontend cache

    - by Utsav
    Our architecture consists of a front-end cache that most read only users obtain their data from directly. The front-end cache sits in front of a farm of webservers that serve pages written in PHP. We need to be able to detect certain conditions at the front-end cache level and pass those values through to the back-end via HTTP headers. For example we would like to manually tag the carrier network based on the IP address. So, for incoming traffic if the user is say coming from an IP address in the range of "41.202.192.0"/19 we would tag them as being a Orange Cameroon user by setting the appropriate HTTP request header, e.g., X-Carrier = "Orange Cameroon". Based on the setting of this header we would like to vary the cache and serve a different banner to the end user. How would you go about doing this? Keep in mind that we don't want to pollute the cache and we also don't want to create too many small cache segments. Assumptions: You can assume that the X-Carrier has already been detected in our cache. So, for the purposes of your test you can just set this value manually in your example script.

  • Convenience of mySQL over xml

    - by Bonechilla
    Currently I use XML to store specific information to correctly load a few things such as a list of specfied characters, scenes and music, Once more I use JAXB in combination with standard compression/decompression(ZIP) functionality to store a list of extrenous data. This data is called to add functionality to the character, somewhat like Skills in an RPG. Each skill is seperated into its own XML file with a grandlist which contains the names of each file with their extensions omitted and zipped in folder that gets encrypted. At first using xml was working fine however as the skill list grow i worry about its stability. I was wondering if I should begin storing the data in mySQL. Originally I planned to simply convert everything to JSON over xml but i think possibly mySQL would be a better move. Can anyone inform me of the key difference and pros and cons of each I guess i'm looking for the best way to store the data more conviently and would be easier to operate on. The data is mostly primatives and strings and the only arraylist of values i have i can just concat into a single field and parse later Edit: If I am going in the right direction with XML would it make sense to convert it to JSON and use maybe Kyro or EclipseLink JAXB (MOXy)

  • Getting MTP to work with a Galaxy tab 2 7.0?

    - by Wouter
    I'm trying to get MTP with the galaxy tab 2 7.0 working on my ubuntu installation. Such that I can access the files. I tried to do what is described here: http://www.omgubuntu.co.uk/2011/12/how-to-connect-your-android-ice-cream-sandwich-phone-to-ubuntu-for-file-access I however fail at executing one of the following commands mtp-detect | grep idVendor mtp-detect | grep idProduct This fails [20:42|0] $ mtp-detect | grep idVender Device 0 (VID=04e8 and PID=6860) is a Samsung GT-P7310/P7510/N7000/I9100/Galaxy Tab 7.7/10.1/S2/Nexus/Note.

PTP_ERROR_IO: failed to open session, trying again after resetting USB interface LIBMTP libusb: Attempt to reset device LIBMTP PANIC: failed to open session on second attempt Unable to open raw device 0 Now my guess was was that the idVender is the same as the VID (04e8) and the idProduct is the same as PID (6860) Now I continued to work with those values and completed the tutorial. When finished I tried android-connect This returned fuse: bad mount point `/media/GalaxyTab': Transport endpoint is not connected Does anybody have a clue what to do? Also I want to note that when I connect my GalaxyTab 2 7.0 that I still get a pop-up of ubuntu that a device was connected. I also can still see the mapstructure, the problem however is is that all the folders have 0 bytes and do not have any subfolders. I can only see the folders in the root. ps. I also checked a similar question and tried what is described in this answer http://askubuntu.com/a/88630/27480

  • SQL SERVER – Follow up – Usage of $rowguid and $IDENTITY

    - by pinaldave
    The most common question I often receive is why do I blog? The answer is even simpler – I blog because I get an extremely constructive comment and conversation from people like DHall and Kumar Harsh. Earlier this week, I shared a conversation between Madhivanan and myself regarding how to find out if a table uses ROWGUID or not? I encourage all of you to read the conversation here: SQL SERVER – Identifying Column Data Type of uniqueidentifier without Querying System Tables. In simple words the conversation between Madhivanan and myself brought out a simple query which returns the values of the UNIQUEIDENTIFIER  without knowing the name of the column. David Hall wrote few excellent comments as a follow up and every SQL Enthusiast must read them first, second and third. David is always with positive energy, he first of all shows the limitation of my solution here and here which he follows up with his own solution here. As he said his solution is also not perfect but it indeed leaves learning bites for all of us – worth reading if you are interested in unorthodox solutions. Kumar Harsh suggested that one can also find Identity Column used in the table very similar way using $IDENTITY. Here is how one can do the same. DECLARE @t TABLE ( GuidCol UNIQUEIDENTIFIER DEFAULT newsequentialid() ROWGUIDCOL, IDENTITYCL INT IDENTITY(1,1), data VARCHAR(60) ) INSERT INTO @t (data) SELECT 'test' INSERT INTO @t (data) SELECT 'test1' SELECT $rowguid,$IDENTITY FROM @t There are alternate ways also to find an identity column in the database as well. Following query will give a list of all column names with their corresponding tablename. SELECT SCHEMA_NAME(so.schema_id) SchemaName, so.name TableName, sc.name ColumnName FROM sys.objects so INNER JOIN sys.columns sc ON so.OBJECT_ID = sc.OBJECT_ID AND sc.is_identity = 1 Let me know if you use any alternate method related to identity, I would like to know what you do and how you do when you have to deal with Identity Column.

  • Data Aggregation of CSV files java

    - by royB
    I have k csv files (5 csv files for example), each file has m fields which produce a key and n values. I need to produce a single csv file with aggregated data. I'm looking for the most efficient solution for this problem, speed mainly. I don't think by the way that we will have memory issues. Also I would like to know if hashing is really a good solution because we will have to use 64 bit hashing solution to reduce the chance for a collision to less than 1% (we are having around 30000000 rows per aggregation). For example file 1: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,50,60,70,80 a3,b2,c4,60,60,80,90 file 2: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,30,50,90,40 a3,b2,c4,30,70,50,90 result: f1,f2,f3,v1,v2,v3,v4 a1,b1,c1,80,110,160,120 a3,b2,c4,90,130,130,180 algorithm that we thought until now: hashing (using concurentHashTable) merge sorting the files DB: using mysql or hadoop or redis. The solution needs to be able to handle Huge amount of data (each file more than two million rows) a better example: file 1 country,city,peopleNum england,london,1000000 england,coventry,500000 file 2: country,city,peopleNum england,london,500000 england,coventry,500000 england,manchester,500000 merged file: country,city,peopleNum england,london,1500000 england,coventry,1000000 england,manchester,500000 The key is: country,city. This is just an example, my real key is of size 6 and the data columns are of size 8 - total of 14 columns. We would like that the solution will be the fastest in regard of data processing.

  • Packard Bell EasyNote MZ35 freezes when AC unplugged and wireless on

    - by Sense Hofstede
    I would like to ask for some help debugging an irritating problem I'm having with my Packard Bell EasyNote MZ35 and Ubuntu 10.10. Always when the laptop is connected to a wireless network and the AC power lead is unplugged—so it's running on battery power—the system freezes. The screen turns black and shows the error GLib-WARNING **: getpwuid_r(): failed due to unknown user id (0), although this error is completely unrelated to the actual problem. Previous searches on the internet indicate that this error is unrelated to the bug I'm experiencing. It is suggested that Ubuntu tries to hibernate or suspend and that you're seeing the black screen running 'behind' the X server. That would explain the fact that curiously you still see—but cannot move—the mouse cursor. I've already set all the values of the GConf keys in /apps/gnome-power-manager/actions/ to 'nothing', disabled all power management actions I could find, but it didn't solve the problem. It is important to note that the freeze doesn't happen immediately after you unplug the AC power lead. The icon in the notification area may have changed already, but the freeze only occurs when the Notify OSD bubble appears that tells you how many time is left with your battery. Does anyone here have a clue about this problem? A workaround or the cause? If anyone could help me with disabling possible suspend/hibernate behaviour that might be related to this issue, that would be appreciated too. This issue has been reported as bug #666852.

  • Is there any way to use arrays in a puppet module (not in template)?

    - by KARASZI István
    I want to use puppet to manage a hadoop cluster. On the machines we have several directories which must be created and set permissions. But i'm unable to add array values for defined methods. define hdfs_site( $dirs ) { file { $dirs: ensure => directory, owner => "hadoop", group => "hadoop", mode => 755; } file { "/opt/hadoop/conf/hdfs-site.xml": content => template("hdfs-site.xml.erb"), owner => "root", group => "root", mode => 644; } } define hadoop_slave( $mem, $cpu, $dirs ) { hadoop_base { mem => $mem, cpu => $cpu, } hdfs_site { dirs => $dirs, } } hadoop_base is similar to hdfs_site. Thanks!

  • Early Z culling - Ogre

    - by teodron
    This question is concerned with how one can enable this "pixel filter" to work within an Ogre based app. Simply put, one can write two passes, the first without writing any colour values to the frame buffer lighting off colour_write off shading flat The second pass is the one that employs heavy pixel shader computations, hence it would be really nice to get rid of those hidden surface patches and not process them pixel-wise. This approach works, except for one thing: objects with alpha, such as billboard trees suffer in a peculiar way - from one side, they seem to capture the sky/background within their alpha region and ignore other trees/houses behind them, while viewed from the other side, they exhibit the desired behavior. To tackle the issue, I thought I could write a custom vertex shader in the first pass and offset the projected Z component of the vertex a little further away from its actual position, so that in the second pass there is a need to recompute correctly the pixels of the objects closest to the camera. This doesn't work at all, all surfaces are processed in the pixel shader and there is no performance gain. So, if anyone has done a similar trick with Ogre and alpha objects, kindly please help.
