[Emil_halim]

Hi everybody

Here is a very early beta version of Magic Library for Ogre, the sources is released for the sake of contribution only , i.e. it is for testing and giving a recommendations and advises.

It may has many bugs and still not optimized yet.

Any comments or suggestions are welcome

If you are interesting , here is a link to Irrlicht version of Magic Library.

Hi Everybody

Here is the first Version 0.01 of Magic Library For Ogre 3D Engine.

Download:

Here is the a ScreenShot of MagicDemo

This belongs in the wiki, not the forums. Please link to the wiki page from your original post, and edit it to remove all that code.

[Emil_halim]

I think that , while it is under construction , so it may be heavily changes ,and some times I need some help to complete it , so that posting it to the wiki in this stage is correct choice.

May be it is wrong forum that I posted in , but did not know which one should I use.

So what do you think ?

Mhh.... I could be mistaken but I thought that all the source code on the ogre wiki is "public domain".
See the disclaimer at the base of the main wiki page:

Wouldn't your license be in conflict if you post on the wiki ?

I would say already posting the code on the forums makes it public domain....

"Iwould say already posting the code on the forums makes it public domain...."

Unless you specifically include a license in the code or post perhaps?

[Emil_halim]

Ok , this may make the picture more clear , the final Magic Library project will only contain a DLL and the headers and the libs and some examples.

So the point of releasing this code is to show you how it internally will be ,so if you think there is an other more optimized and enhanced approach you code tell me.

So the a license in this case is not important.

Hope it is clear by now.

[Game_Ender]

So you are releasing only the source to this version, and then once you have gotten advice on how to improve it you will just release binaries?

[Emil_halim]

Yes , and if any one want to keep contribute , I can share the sources with him .

An other thing , if you take a closer look for Irrlicht one you will see that , although it is closed sources but there are more than 100 examples with their open sources to show you how to make many effects.

@Emil_halim:
You have made my day! I was using Magic Library in Irrlicht, and when I switched to Ogre, I really began missing it! I am going to start "testing" the class right now in my app. It is great to see it ported to Ogre. Do you plan to keep the same member function names, classes, and such? I hope you do. Anyways, great work! I can't wait for the official binary release!

[Emil_halim]

Do you plan to keep the same member function names, classes, and such? I hope you do. Anyways, great work! I can't wait for the official binary release!

I am afraid no, because Ogre differs from Irrlicht , but if you want the old names there is a trick that you can do , use a macro to rename them , i.e. #define OldName NewName .

[irrdev]

I'm sorry to hear that the functions calls will be different, but it is understandable. Good tip about the #define Oldname Newname, I haven't ever thought of using that!

Why is the rendering window header so Different to what I know ??

He used a different theme from the usual one.

[Emil_halim]

Ok , after doing some benchmark and test speed to make comparison between Oger version and Irrlicht version , I decided that , I will not work with HardWarebuffer and do all darwing stuff with pure DirectX and OpenGl , and keep setting render states by using Ogre RenderSystem.

[Vectrex]

interesting..
I found some spelling mistakes
BLINDTYPE = BLENDTYPE?
Distroy = Destroy

These aren't mistakes but it'd be nice to avoid unnessesary abbreviations and weird names
mScrnWidth
mZZRotate

[Emil_halim]

thanks Vectrex,

i will correct them soon.

[Emil_halim]

ok , I have add a new function ‘ DrawImageToFitArea ‘ which allow you to fit the size of our image to a specific dimension on the screen.

This version will work only with Directx render system , I will make an other one for OpenGl soon.

Hi EveryBody

Here is what I have implemented with MagicLibrary So far , of course there are still many functions that I will do.

Prototype of MagicDXManager Class

Code: Select all

enum BLENDTYPE
  {
    SOLIDBLEND = 1,
    ALPHABLEND,
    LIGHTBLEND
  };

       BottomLeft,
       BottomRight,
       AllPoints

       TexturePtr tp;

};

Why don't you put this stuff on the Wiki?

[Virion]

maybe you can just list out the name of the functions and their uses in the forum, and post the codes in the wiki?

[Emil_halim]

Why don't you put this stuff on the Wiki?

I am just little confused , where should I make My MagicLibrary page in the wiki , which page the suitable for this category.

Any help please ?

maybe you can just list out the name of the functions and their uses in the forum, and post the codes in the wiki?

I am afraid , I am not willing , and it is a closed source project.

[Vectrex]

you could update your first post with the latest code/headers and add a 'edit' + date type thing

[elesgal]

I am afraid , I am not willing , and it is a closed source project.

btw what is so special in it that it is a closed source project?

[Emil_halim]

Mr elesgal

It is closed project not because there is something that SO SPECIAL in it , but it is my own desire , besides the drawing stuff is not rely on Oger .
