But you should not post incorrect statements (if that's the case here).

why you say that ,it is incorrect statements

last year,i was developing BCXDX9 for BCX basic Like language and .......

please see this links

you see now , it is not my own thought.

Hi all

here is the first help file for Magic3D Library, you know that it is beta version.

here is the link
http://bcxdx.spoilerspace.com/BCXGL/Magic3D_Help.zip

created by doxygen program.

Yeah Emil halim is correct because the devpak disapeared quickly after realease because it was built by reverse engineering the microsoft compiler libs

well its not reverse engineering but something like this wchich can be excuted in the home(and stays at home to be legal)

Hi all

here is an update of Magic3D Library , still under testing stage.

added features
==============
+ adding fading effects to CBaseMagicSceneNode class , so that each object of Magic3D could fade in and out.

+ added splash window

+ added setOrthogonal for C2DImageSceneNode class.
CAnimSpriteSceneNode,CStaticSpriteSceneNode,CFontSceneNode could drawn Orthogonaly
whuch means that they do not affected by camera movment.

+ added CFontSceneNode which allows you to write a bitmap font text.
it has some useful friend functions such as
. TextLength() return the length of text in 3D space world.
. CenterX() return x coordinate to automatically center the text in our screen

+ added CMovie,CMovieMesh class for playing movie in your scene.

+ added CTime class.

here is a screenshot of a demo
i have added the CSkyDomeSceneNode to the demo for better looking,created by alc

downloading here

Enjoy it.

hi all

this is my last release of magic3D library under Dx9, i have found many things that disappoint me when working with Dx so that i will go back to OpenGL.

Thanks for your continued work Emil, hope it can be integrated with the regular Irrlicht build. Wouldn't it be great?

Edit : FORGET this post I have resolved the problem.

Hello all, my first post!

First I must say a big thank you to Emil because his work is helping me a lot.
Now the question: I have followed the tutorial 'Drawing text in texture' (http://www.irrforge.org/index.php/Drawi ... in_texture ) written by Emil and it works fine under Directx9 renderer but it doesn´t work under the software renderer.
I'm writing a small application for a specialized hardware and i must use the software renderer.
The tutorial crashes on line : s32 x1 = Positions[chr].UpperLeftCorner.X;
in DrawString() func.
It seems a buffer is too small or something like that. (Edit: It seems chr is too big and goes out of bounds of 'Positions' array. I don't really know what is 'Positions' used for. Any help? )

Does this also happens in Magic library ?
Do you know how can i fix that ?

Hi Evrybody

i am working in developing Magic Library "only for OpenGl", i tring to apply shader effects to mesh as i do for 2D Image.

my first example is to apply a blur for Mesh by using small shader program and here is a screenshot

the left one has blur effect and the rghit one has no effect.

here is the code

i will release the Magic Library sooner.

wow, it is very nice to the see the lib covering both 2d and 3d

I am going to downlaod it and hopefully integrate the cg shaders, i hope translating my shaders to cg would raise their compatiblity (my glsl ones only work on nvidia

)

keep up the great work!, this lib provides all lot of time saving classes when people want 2d,3d special effects

Posted: **Thu Jul 27, 2006 6:31 am**

thanks Omar.

i have not yet post the new release of MagicLibarary which has cg features
, wating to finishing it.

i have nvidia also,so your work could integrated easly with my work, i hope that.

here is a new demo called Phong lighting.

No i meant to ask does it work on ATI, my glsl only works on nvidia because ATI has a very bad GLSL compiler

oh, sorry i got it wrong.

actually , i do not test it with ATI , also i do not have ATI ,my be the users could test it and tel us the results.

Irrlicht Engine

Magic Library - True Type windows font

Draw text on texture doesn't work with software renderer.
