opengl - WGL: No double buffering + multi sampling = FAIL? -

-

I usually use wglChoosePixelFormatARB () with these arguments (among others) Create a pixel format:

WGL_DOUBLE_BUFFER_ARB = GL_TRUE WGL_SAMPLE_BUFFERS_ARB = GL_TRUE WGL_SAMPLES_ARB = 4

i.e. double buffering ON and X4 multisamming works just fine .
But when I try to turn on double buffering: 

  WGL_DOUBLE_BUFFER_ARB = GL_FALSE WGL_SAMPLE_BUFFERS_ARB = GL_TRUE WGL_SAMPLES_ARB = 4

to make a call wglChoosePixelFormatARB () fails (or indicates that it has not created anything)
When I turn off multisampling effectively: 

  WGL_DOUBLE_BUFFER_ARB = GL_FALSE WGL_SAMPLE_BUFFERS_ARB = GL_TRUE WGL_SAMPLES_ARB = 1

I work fine again

Is there something underlying that works with multisamming Prevents non-double-buffer pixel format?

This is because I'm discontinuing double buffering to get unrestricted frame rate, with double buffering of the frame rate I get, up to only 60 fps (this laptop works on LCD 60Hz is). But with double buffering, I can reach 1500 FPS. Is there any way to achieve this with double buffering?

In theory, drawing mode in single-buffer means that you are being presented directly on the screen (Front buffer aka) are revised. Since that memory is already in a specific format, you do not have to choose another. (I'm saying in principle because the platform delights in behavior though. Arrow, for example, does not allow access to front-buffer).

In addition to this, multisamming, this step converts X sample / pixel to 1 pixel, when the back-buffer is copied to the front buffer (called the resolution phase) is. In single buffer mode, there is no such step.

As your 60 FPS locking, you probably want to see it. The point here is that you do not want to update the updates shown on the screen, while the data in the screen is refreshed; It tearing, by default, swap updates only when the screen is vertically synchronized (aka Viscink), so that you can lock the screen's refresh rate.

If you do not see your display as separate frames, you can turn it off.

For completeness, triple buffering is an alternate mode, in which the GPU ping-pong rendering is basically between 2 back buffers behind the buffer, while the front buffer is shown. This is dependent on the GPU to select the end-ended back-buffer when the time shown on the screen (the Wiener) comes at a time. Unfortunately, I'm not aware of the WGL method to ask for triple buffering.

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
