RE: [Flightgear-devel] Re: UDP port into the property tree
From: Melchior FRANZ [EMAIL PROTECTED] * dene maxwell -- Friday 17 February 2006 05:53: What port number for write ? What port number for read? (I prefer confirming protocols) That's called TCP, then. Yes, that's possible. Just run fgfs with --telnet=5500, then you can telnet into it and read/write to properties. $ fgfs --telnet=5500 Then wait until it's running, and from another terminal window telnet into it: $ telnet localhost 5500 help Valid commands are: cd dir cd to a directory, '..' to move back data switch to raw data mode dump dump current state (in xml) get var show the value of a parameter help show this help message ls [dir] list directory prompt switch to interactive mode (default) pwddisplay your current path quit terminate connection run command run built in command set var valset var to a new val show var synonym for get And the whole telnet/socket connection can also be done by a script. Look into scripts/ dir for examples. What format to access each property? Start withdata Then read... get /position/longitude-deg get /position/latitude-deg Or write ... set /sim/foo 123 and finally quit This way you can do about everything. Read/write properties, execute built-in commands, or transfer arbitrary Nasal code and let fgfs execute it. You can even transfer whole dialogs and pop them up in fgfs. m. That would suit my needs exactly if; a) I wanted to do it manually b) I could start a telnet session from within VB6 (not saying you can't just I haven't yet) was really hoping that it could be treated like an object using UDP. eg set com1.freq=129.6 set nav1.pri.freq=103.3 set nav1.sec.freq=105.3 set nav1.radial=161 set adf.freq=234 will have to investigate starting a telnet session within VB if no other ideas come to pass Cheers, thanks for the suggestion =Dene _ Shop til you drop at XtraMSN Shopping http://shopping.xtramsn.co.nz/home/ --- This SF.net email is sponsored by: Splunk Inc.

Melchoir, just looked up MSDN, I quote; Using the Winsock Control A WinSock control allows you to connect to a remote machine and exchange data using either the User Datagram Protocol (UDP) or the Transmission Control Protocol (TCP). Both protocols can be used to create client and server applications. Like the Timer control, the WinSock control doesn't have a visible interface at run time. Possible Uses Create a client application that collects user information before sending it to a central server. Create a server application that functions as a central collection point for data from several users. Create a chat application. Selecting a Protocol When using the WinSock control, the first consideration is whether to use the TCP or the UDP protocol. The major difference between the two lies in their connection state: The TCP protocol control is a connection-based protocol, and is analogous to a telephone the user must establish a connection before proceeding. The UDP protocol is a connectionless protocol, and the transaction between two computers is like passing a note: a message is sent from one computer to another, but there is no explicit connection between the two. Additionally, the maximum data size of individual sends is determined by the network. The nature of the application you are creating will generally determine which protocol you select. Here are a few questions that may help you select the appropriate protocol: Will the application require acknowledgment from the server or client when data is sent or received? If so, the TCP protocol requires an explicit connection before sending or receiving data. Will the data be extremely large (such as image or sound files)? Once a connection has been made, the TCP protocol maintains the connection and ensures the integrity of the data. This connection, however, uses more computing resources, making it more expensive. Will the data be sent intermittently, or in one session? For example, if you are creating an application that notifies specific computers when certain tasks have completed, the UDP protocol may be more appropriate. The UDP protocol is also more suited for sending small amounts of data. Regards =Dene _ Need more speed?

Re: [Flightgear-devel] Global data positional lookup
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 David Luff schrieb: I'm considering the problem of looking up global data at the moment (eg. how many navaids are within x miles of point p). So far I've only implemented this in a very crude manner, by indexing a map of navaid pointers using FG bucket number, and then traversing all the navaids in the user's bucket and concentric rings of buckets out from the user to the required distance. This works, but is somewhat ugly, and requires more navaids / buckets to be checked than may be necessary due to the non-square bucket size and potential for non-centered position of the user within a bucket. I'm sure there must be a better way, and I'm sure Norman has posted links on this subject to the list before, but I can't find them, and can't seem to find a good method. Anyone got any ideas? OK, this comes up once in a while (writing the WeatherCM code ages ago I also had that problem). Perhaps it's time to solve generally. The basic and ugly algorithm is to iterate through all points. This takes at least O(n) and can be as bad as O(n^2) when I need e.g. the distances between all points. 1) The usual solution is to create the delauney triangulation. It will take O(n log n) to generate it and look ups can be quite fast as we know the topology of the points. This was my approach with the WeatherCM code. The used library should still be somewhere in the FGFS codebase. (It's an extended version of the triangulator to work on a sphere) 2) The sugested Quad-Tree (or Octtree) approach also might work with the algorithm you've described (actually the buckets are a sort of quad tree with only one level) 3) Interesting would be the use of a space filling curve ;) There you can easily compute (O(log p) which we can assume to be O(1) in our case) a index number out of the coordinates and then store all points in the order of the index number. When you are now searching for points that are close to a given one you just have to look upwards and downwards from the index of the point you are interested in (this point can be anywhere). As the usual space filling curves are Hölder Continuous(*) this works quite good. The most simplistic way to solve the problem is IMHO the use of a space filling curve together with an STL map. This will result in only very few lines of code and give us an quite fast and universal lookup scheme. CU, Christian (*) Hölder Continuous to the exponent r basicly says that there's a C0 that fullfills: ||f(x) - f(y)|| = C * |x - y|^r In the case of the n-D Hilbert curve (a very simple space filling curve) r = 1/n, so in the 2D case: ||f(x) - f(y)|| = C * sqrt( |x - y| ) Or more graphic: the distance between two indices limits the distance that the two points in space can have. -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.0 (MingW32) iD8DBQFD9d7flhWtxOxWNFcRAj3jAJ4l0lLJqnwKY/bTnFd8cwK/kwIA1gCfSt/n vo9XIlH/9KfOvLhyBfQHXJY= =6x/z -END PGP SIGNATURE- --- This SF.net email is sponsored by: Splunk Inc.

Re: [Flightgear-devel] Re: UDP port into the property tree
Hi, ... Telenet being a application layer protocol requires alot more details as to recipient and also alot higher overhead to implement...whereas UDP being a trasport layer protocol is less distinct in is destination and requires less overhead to implement. I'm not sure what you mean about less distinct in destination, both TCP connections and UDP packets must go to a specific destination address (although you can use UDP to a broadcast address on your local LAN). Andy Exactly, TCP is point to point and UDP can be used for broadcast. The winsock control can do TCP or UDP with equal ease. Although I've only had experience using UDP because it's all I've ever needed to use (as per MSDN's recommendation that TCP be used for transferring large amounts of data and UDP for simple messaging type uses). The issue is the command structure that surrounds setting values in the property-tree... This is obviously written to cater for manual Telnet sessions. I was asking if there is access to the lower level that by-passes the need to use the command-structure (opening a session closing a session plus the other commands that were in there) and be able to treat the property-tree purely as an object that set or get type instructions can be issued to. Not that it is difficult to emulate the command-structure using either TCP or UDP. was just asking though. Cheers =Dene _ Looking for love?

Is there a way to change that (or at least have an option for the original behavior.) Solid points look a lot better on all the monitors and resolutions I've tried.

In renderer.cxx:
if ( SGIsOpenGLExtensionSupported(GL_ARB_point_sprite) ||
SGIsOpenGLExtensionSupported(GL_NV_point_sprite) )
{}
But please make it an option rather than removing the code, the point
sprites are better than anything I have seen before.
Can we control the size of the sprites? It appears that what we are
drawing is subpixel size so it flickers in and out depending on how the
floating point math rounds out.
Curt.
