Irrlicht Engine

Oops.. yeah, I've tried git-svn quite a long time ago.
But it may be my incompetence that I figured I'd better
keep the git and svn repositories independent to each other.
Can't remember in detail what caused me to think that way
though....

I'll try to learn git-svn, again. Thanks. :p

According to the working flow of corresponding methods and classes,
the leakage should be pretty unlikely, but I've corrected the code
nonetheless, thanks vroad!

I only patched the main 'cubeat-irrlicht' branch in my repository,
so if anyone else happens to be interested in this, please make sure ...

I must apologize, I've been busy working on the day job
and didn't see your post..

and .. wow, thanks for the fix, I'll look into it ASAP! :D

about the 8bit thingy, thanks for pointing out, as I was
not familiar with Direct3D programming. However, I'm afraid
that I will not be able to dig into ...

Load 8-bit grayscale texture with OpenGL is pretty easy,
I've tested it with NeHe's OpenGL Tutorial code. But to my
dismay, Direct3D9 just doesn't support that. The most compact
format both drivers have in common is A1R5G5B5.

Even if there's any possibility to make this work on both
drivers, it ...

By all means

I did add some comments on critical parts of my changes,
but maybe not all of them are well-commented. In case of
confusion, please let me know.

I am still in the process of reducing memory usage of this new method,
already cut the memory usage in half. The CGUITTGlyphPage now holds
only video::ITexture; video::IImage is dropped. Each SGUITTGlyph holds
a video::IImage of its own glyph bitmap again; however, when the
page->updateTexture() is ...

I've just tried to apply paging method to my addTextSceneNode
function, the FPS boost is very significant

But I'm still figuring out the abnormal memory usage after
I apply this method, and doing some code clean-up as well,
I'll update my original post as soon as possible.

Ok, I'll update my code accordingly as soon as possible.

Thanks again!

That's definitely extraordinary! :)

After a first glimpse into the new code base, I figured the
code structure hasn't changed much, so I think I can live with
that.

I see now the newly added GlyphPage structure holds the
video::ITexture, so I think mainly I just have to change how my
planes get ...

Thanks to warn in advance :)

Just a little question though, how do you manage to stick all
font textures into a single texture atlas if that font has like
, say more than a few thousands or even tens of thousands glyphs?
Because that's the nature of multi-byte languages,
if you just stick them all ...

I recently found out the IrrlichtML project is still continuosly
updating to the newest Irrlicht version, I am so happy :D

http://etwas.wolfish.org/Irrlicht/irrlichtml_en.html

In my project I used their code to pump out font textures which can
be used on a simple plane in 3D, so I can make those ...

Ok, in order to use this code snippet there are a little more steps than
just simply paste this into COpenGLMaterialRenderer.h :p

first...
paste the code in the original post into COpenGLMaterialRenderer.h XD

second,
add EMT_TRANSPARENT_MODULATE to the EMaterialTypes.h enumerations,
and add ...

Sure, there you go. ; )

I added the following code to the OpenGL material renderers,
Because I needed a transparent material which will take
BOTH texture color AND diffuse color into consideration.

*update*: You'll also need to add a few lines to EMaterialTypes.h and COpenGLDriver.cpp

Irrlicht provides a lot of animators to go along with 3D SceneNodes,
but what if I want to use animators with GUI elements?(or other 2D stuffs)
It's like, when the mouse hover through a half-transparent GUIButton,
it becomes solid "gradually" (or becomes glowing).

That is, more or less like a fade ...
