html5 - How to draw a 3D sphere? -

-

I want to make a 3D ball or sphere in the HTML5 5.0 canvas. I have to understand the algorithm how to attract a 3D area. Who can share this with me?

Update: This code is too old and limited now to 3D areas There are libraries to create: Ten years ago I wrote a Java applet to actually perform a texture field for mathematics where the surface of the goal was the view (not using the triangle).

I have written it again in the javascript for canvas and let me know :

22 fps on my machine, which was based on as fast as the Java version, which render it, if not a little faster!

Now that I wrote the Java code, it's a very long time since then - and it is very low - so I really remember this really how it works, I just got it javascript Although it is from the slow version of the code and I am not sure if the Java version has a faster version due to the traffic used to manipulate the script or works faster in mathematics It renders what pixel to pixel to work texture. I was also at the same time with an applet which was very fast compared to me but I do not know if any of the speed improvements would be possible in Javascript because it can rely on Java libraries (I own Code never seen, so I do not know how they did it.)

Then it may be possible to speed it up . But it works well as proof of concept.

If you are interested in comparing the speed, then the Java version is here:

These are deadly links until I update my website

  • - This version is also lighted
  • - Fast to start, too fast to render .

    • I can see if I can get any speed improvement in the javascript version, to see my quick version There is a way to change

    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...
