Irrlicht Engine

Thanks everybody,

For your kind help. I used slavik262's code almost verbatim, and it worked like
a charm.

Best regards

So slavik262,

In order to create IImage * from a png or bmp file, I will have to use FreeImage library. Is that right way to go?

Best regards.

Thanks slavik262,
Looks like a good instructional material. I am hoping to learn quite a few things from this.

Here is the program, // // // g++ -I/home/laeeq/irrl/irrlicht-1.7.1/include -L/home/laeeq/irrl/irrlicht-1.7.1/lib/Linux tt_2.cc -lIrrlicht -lGL -lXxf86vm -lXext -lX11 // // #include <irrlicht.h> #include <unistd.h> using namespace irr; using namespace core; using namespace scene; using namespace vid...

Thanks slavik262, I replaced the line tex_1->drop(); with this line, driver->removeTexture(tex_1); but this results in segmentation fault right when removeTexture() is called. May be slavik, your technique of copying image to texture is the way to go. Please give me some initial steps or post the co...

Hi Bate, Can you explain what you meant when you said, Yes, Irrlicht loads a texture only once. If I execute following code, ITexture *tex; tex = driver->getTexture("file_1.jpg"); // And then I do tex = driver->getTexture("file_2.jpg"); Where will the pointer tex be pointing in t...

Is it true that, if I do, tex_1 = driver->getTexture("/home/laeeq/multi_media/png_seq/FCAJ_BigWin/FCAJ_BigWin_025.png"); and do this again, tex_1 = driver->getTexture("/home/laeeq/multi_media/png_seq/FCAJ_BigWin/FCAJ_BigWin_025.png"); then this NOT a memory leak? Irrlicht some ho...

Hi, I wanted to display an image, and after displaying the image I wanted to free the memory, (so that I can use it to display some other image). Here is what I did, // // // g++ -I/home/laeeq/irrl/irrlicht-1.7.1/include -L/home/laeeq/irrl/irrlicht-1.7.1/lib/Linux tt_2.cc -lIrrlicht -lGL -lXxf86vm -...

For rotating part, wont following way work?

Hi slavik262, This idea of copying pixels directly onto texture sounds interesting and promising. But I need some help in how to actually do it. I looked into the member data fields of ITexture class, but couldnt find any member where I can copy pixel data into. I would appreciate if you could give ...

Aha,

Thanks slavik262 & hybrid for helpful response. I will try these approaches and report back.

Regards

Oh sorry, I thought you create the texture with addTexture. But getTexture basically does the same. The point is that a hardware texture is created each time this method is called with a new name. So you have to clean up afterwards. You cannot render an image to the screen, it has to become a textu...

Thanks Bate,

Does this player work only on Windows or it can work on Linux also?

Thanks hybrid, I am afraid you over-estimated my knowledge of Irrlicht, I didnt get what you meant by " Since you use a method with 'add', " I am using draw2DImage() method. Is this better to use IImage class in this kind of situations, since all I want is just load an image file and displ...

I am sorry, the above message got posted pre-maturely. This program works, But my question is, in this approach, shouldn't we be de-allocating memory for the texture generated from each png file? Other wise it seems to me, there is memory leak here, and there will be maximum limit on the number of f...
