Graphics

26-Jul-07 23:56

I got a problem with my opengl wrapper class... Basically, I've been designing an portable API for all my needs. Audio, Graphics, GUI, Resolutions, LANning. etc. But my OpenGL wrapper class is in real need of help.

It does everything wonderfully, except the following:

when the win32 window is fullscreen and borderless the initial buffer flickers accross the ever changing current rendered screen,
and i need help with my font loader, I cant get the draw text procedure work.

Help me out, I will give credit where due, thanks.

Here's code from my windows class that I think will matter:

<br />
void register_stapi_classes();<br />
HWND create_window(const c8* class_name, const c8* title, const DWORD extra, const DWORD style, const vector_2d<s32>& tl, const vector_2d<s32>& br,HWND parent =0);<br />
<br />
<br />
//ctor<br />
window::window(const_string _caption, bool _border, bool _resizable, const_vector _tl, const_vector _br) throw(win_error)<br />
: mborder(_border), mresizable( (mborder)?_resizable:false), mclosed(false), mcaption(_caption), parent(0), current_cursor(new cursor), icon_file("")<br />
{	<br />
	register_stapi_classes();						//	register with windows if needed<br />
<br />
	DWORD style = WS_POPUP;							//	default to no border<br />
<br />
	if(mborder)<br />
		style |= WS_CAPTION | WS_SYSMENU | WS_MINIMIZEBOX;		//	make a border if need be<br />
	if(mborder && mresizable)<br />
		style |= WS_MAXIMIZEBOX |WS_THICKFRAME;					//	make resizable if need be<br />
<br />
	ready = false;<br />
<br />
	wnd = create_window(sapi_main, mcaption.c_str(), 0, style | WS_CLIPCHILDREN | WS_CLIPSIBLINGS, _tl, _br);	//	make the window    <br />
<br />
	<br />
//	the following doesn't work with opengl well, disables almost every opengl capability<br />
	//SetLayeredWindowAttributes((HWND)wnd, 0, 255, 0);// | LWA_COLORKEY); WS_EX_LAYERED<br />
    <br />
	mdimensions = new wdimension(wnd);<br />
	mcommoncontrol = new wcommoncontrol(wnd);<br />

	ShowWindow ( (HWND)wnd, false);					<br />

	run();<br />

	mcommoncontrol->visible(true);					//	display the window<br />
}<br />
<br />
//destructor<br />
window::~window()<br />
{<br />
    win_hash.erase( (HWND)wnd);<br />
    if(IsWindow((HWND)wnd))<br />

<br />

	}<br />
	<br />
	style |=  WS_CLIPCHILDREN | WS_CLIPSIBLINGS;<br />

You better read the posting guide lines[^] and report your question. There isn't a single person here that's going to read all that code.

My bad... Umm... then i'll just restate my dillema in short... My fullscreen OpenGL window flickers... Any ideas why??

hmm... Unless, I try a stripped down win32 window...

see if it's not my window attributes...

if that don't work, I'll try a stripped down OpenGL wrapper class.

If that don't work...

help?

Well, I try this out, could I ask for any feedback?

Oh, Thanks a ton for not coming down on me for that long post... I just cut and pasted, didnt expect it to be as long as that lol Smile | :)

reducing the problem to the least complex definition allows for rapid testing of new techniques as well as diagnosis of problems related to a specific interface (windows). I am not likely to look through all that code either. You can compare against other implimentations of windowing GL code (Nehe, and others) to see if you did something obviously wrong.

Thanks for the advice El Corazon, strangely enough I just gave that advice to my IT class, lol...

And lo and behold... Windows attributes people... It got so bad wglMakeCurrent(0,0) crashed the program... even in my previously working back-ups

Finally i have returned to my window class, and have rebuilt it from scratch... it is looking a lot more tidy if i might add

once again, thanks for the feedback.

nehe rules everyone, haven't looked at it in ages (lol) but it is a brilliant source to turn to for some heads up and know how of OpenGL code...

viva OpenGL...

That poses another discussion...

do you think OpenGL 3.0 will every see light, with the dawning of DirectX 10's completely new structure...

a mag that i read said that it highly unlikely that OpenGL will come close to its opposition... but i rekon, that given the time and effort... anything is possible when it comes to coding our friendly beasts... The PC

yes. All things in time.

Perhaps, perhaps not. Microsoft has the advantage that it does not answer to a committee, that means changes happen fast. Still OpenGL has broad support in multple platforms, so holds its own. I don't think it is going away. Microsoft has settled it's dispute with the OpenGL committee by ignoring it, but letting other companies support it. That will work as long as it works, no more, no less. But... on the plus side, MS has tried to kill OpenGL now 3 times and failed every time, 4 if you count the failed Fahrenheit project that was to merge DirectX and OpenGL -- that was killed.

haven't tried it... sounds pointless at the moment... but it's cool to know thats possible... especially because DirectX 10 has certain features, like programming on the GPU... then again do we want to merge them... and if we gonna use DirectX at all, why use OpenGL to that effect... unless you want the engine to be semi cross-platformable... in which case, just use DirectX in class that has the same polymorphic ability....

Once again... why merge 'em?

strange...

This was a failed attempt to create one non-competing standard for all platform graphics, replacing both DirectX and OpenGL. It failed because of the power struggle within the committee. Sun still holds a grudge against MS and MS still holds a grudge against a few others. The idea was that without the competition they could work on creating a super set of functionality on the scale of a full scenegraph as well as low-level functionality. The project tore itself apart internally and the result was we still have DirectX and OpenGL as competitors for "some" markets. Some meaning that cross platform there still is no choice.

In OpenGL 2.0+ you can do some GPU programming. It at least doesn't prevent you, you even have a choice of GPU languages depending on your personal favorites (CUDA, Cg, OSL, etc.). I've been doing GPU programming using vendor extensions since 1.5 was released.

Hi. Is it possible to embed DirectX application in a C# Windows form? The problem is that the application is written in C++.

Due to DirectX being involved, more than likely not.

I don't know about embedding applications in forms, but...

The newer/newest DirectX SDKs include separate documentation for managed languages.
The info should be there.

Hi,

I draw some graphics in a form,such as rectangles,lines.Now when i double click the form,how can i know which graphics i selected or i selected nothing. and then i want to do something with the graphics.

In other say ,how can i get the graphics when i click it??

i use C#

.NET Image Processing library for WinCE

Hi,

Im hoping someone here can help...

I am involved in a project that needs to perform some image analysis on an image to interpret results. The functions I need are as follows: scaling image, image rotation and finally analysis at a pixel level. We are running on WinCE and coding with C#. I am able to find image processing libraries for WinXP which unfortunately don't work on WinCE due to the cut down functionality in Compact Framework 2.0.

I haven't been able to find a WinCE compliant package. Maybe someone here knows of one? Any other suggestions?

Hoping for some leads... Sigh | :sigh:

Regards,
Myron

How to match a usb camera between DirectShow and WMI?

Clark Nu China23-Jul-07 14:33

Clark Nu China

23-Jul-07 14:33

For a camera which support DirectShow, I can easily get it used via DirectShow, preview video, capture image, record, and so on. Now my problem is I want to know which usb controller and port the camera I'm using is conneted to. I can also get all usb controllers and usb cameras and their connection map via WMI, but can not match the same usb device bewteen DirectShow and WMI. Is their a identifier for me or some way else?
Thanks

reading vectors values of type static from file

how are the vectors defined... generally I have a vector < some3dstructure > storage. and then I simply read into some3dstructure and then push_back(some3dstructure) into the vector. This makes it real easy to read/write binary data. Text data is not really a little more difficult, but rather just a few more steps to keep track of and get right.
