I had created a 3D cube so that it can rotates around a point.
However, when the cube is drew, some faces will disappear in certain angle while other diappear in another angle.
Can anyone please help why this occured ??
Or can anyone give some example on how to programme it??
Thanks very much!!

i think that is a problem of the normals.
a normal tells a face in what direction to reflect the light, so when u look at its back, u won't see it anymore.
remove the calls to glNormal3x and it should be fine.
Don't try it, just do it! 
|
|
|
|
|
In fact, the problem now is that,
The six faces of the cube just like have their own 'priority',
such that one specific face will always on top
and then the second and third.... according to the 'priority'....
can this be solved ??
Thanks very much...

Sounds like you have depth buffering disabled. You'll need to have a depth buffer created when you're creating the OpenGL display, you'll need to enable depth testing (with glEnable(GL_DEPTH_TEST)), and you'll need to clear the depth buffer at each frame (glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)).

I have checked the depth testing is enabled and the buffer was clear each time...
I doubt if the GLUPERSPECTIVE will also cause this problem...
Can anyone tell me how to use this function ??
I have looked at the document of the GLUPERSPECTIVE but I dont think it really help...
BTW, what does "clipping plane" mean ??
Thanks very much again and again...

Have you checked the order of your points (glVertex's) defining the cube?

Hello, I need a comparison from you guys please.
If I gave you a spec for a simple business app. Gui front end with OO backend and sql server database and told you it would take around 1500 hours to do in c#, how long would you say the equivalent in visual c++ would take from your average decent c++ coder? I am not good enough with c++ yet to make a determination for my client.
The app is nothing more than db access. Manipulating data in a database. There will be one section that will read from excel and import to the database.
What about the same system written in c++ that would run on linux and db2 as a backend? How much overhead would this add to the VC++ version on Windows?
Thanks!

you can't really compare (IMHO) ; there are too many factors involved, libraries used, verbosity of the language, facilities of integration with DB (libraries)... and the maintenance factor.
if you start talking about multiplatforms, then, your choice of language is reduced, I don't think a version of C# exists on linux yet; and you need to get a good enough toolkit for the GUI for both platforms ( windows and linux ), in that case, you choice is reduced to C and C++.

Yeah, we started doing it in c# then they decided to maybe go to linux. I'm trying to get a feel for how long a write would take in c++. If they do go to linux, it would only have to support linux.
If you had open reign to do this project in c++ on linux, knowing it would take about 1500 hours in c# for Windows, can you give me a general comparison? Would it be 3x as long? 6? etc. I just need general numbers.

If you want a nice multiplatform C++ toolkit use Qt[^]. The commercial license is a bit pricey (~ $2500 USD) but it is very nice. I would guess the time to be comparable as Qt is a large framework with much of the same functionality as .net, and they have built in database support, which I take it is a big deal for you on a project like this.
I'd like to recommend the VCF[^], but unfortunately it's not completely ported to linux, and it has no database support.

Thanks, I'll check it out. Can you give me any time comparisons? If I used Qt can you give me a very rough estimate compared with 1500 hours in c#?
Thanks!
Price of it doesn't matter...Just roll it over to the client...

Couldn't tell you. Assuming you learn the Qt API reasonably well (and it looks quite easy and logical, so I can't imagine too many pitfalls in learning it, certainly no more than learning .Net API's), I'd guess the time to roughly equivalent, at least for the GUI implementation.
But I'm completely guessing here, sorry I don't have more info for you!

You don't necessarily have to use C++ for the Linux port; depending on your setup, you may be able to use Mono[^] to compile and run the C# app under Linux for a number of different architectures.

Mono is at 0.3.0 right now. Would you run your production system on a pre-alpha platform?
|
|
|
|
|
Yeah, I looked a Mono also, but it's way to early in the game to use it. Won't be ready in time for us either.
|
|
|
|
|
And lets not forget that they are copying a system that Microsoft has *publicly* stated that they are protecting with patents. I simply cannot imagine MS *not* using these at some point if Mono gets any traction beyond the hobbyist programmer.

A project like that that needs to be cross-platform really should be written in Java. Run the same code on Windows, Linux and most other Unixes. Easier to code than C++ (especially since all the platform-compatibility issues are taken care of), rich, mature libraries and plenty of 3rd-party free and commercial stuff you can build from.

Java is probably the language I know least about. I only need it to run on Linux right now. Is java capable of doing a high volumn call center app? Will it be fast enough? Most of it won't be web based, but client based with a sql server or db2 backend.
TIA

This type of application is very typical of what people have been using Java to do. IBM's whole Linux push is based on Java applications.

hi,
i have created an array
UCHAR * data;
data = new UNCHAR [size]
i saved data in it ,, that PCM data (pulse code modulation)
now i want to send this (array) throught socket.
how can i
CSocket->send ( ...... , .. , ...);
Plz reply me
thanx
|
|
|
|
|
I dont know the exact syntax for CSocket but I use something like the following for sending a struct through a SOCKET..
// where sSend is a struct containing CHAR's and INT's
send(sock,(char FAR*)&sSend, sizeof(sSend), 0);

hello ,
i want to load icon & text string in a combo box, like the following...
-------------------------------

like that
------------------------------------
how to do that in run time in a dialog based application and form based application projects ....where these r frequent ?
waiting for reply.....

Can you use CComboBoxEx?

When creating a standatd multidoc MFC application with class wizard there is a menu that enables the user to hide the toolbar or statusbar i wish to implement something similar in my application however, with multiple toolbars.
i went through the class wizard's code sample and i could not find the implementation of the menu - the MSDN sais that in order to implement the menu one shold override their imlementation but the don't say how.
please help me.
