Irrlicht Engine

I don't use different texture for each draw call,many draw calls share same texture ,I just tested to see how spritebank works, but there is no improvement if I use draw2DImageBatch() because it use NullDriver::draw2DImageBatch() that don't do nothing than looping between modules(rectangles) and ...

After reading this post http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=43891 I realize that I should cache all vertices and and use drawPrimitives ... method, but still think that it will be much easier if this could be done at opengl-es driver level for 2d rendering and have a flush2D ...

Hi,

we need somebody with a very good 3D knowledge to optimize the opengles 2D image rendering, I have a 2D sprite animation engine using draw2dImage to render frames and seems that the FPS drops drastically (under 10fps) when rendering over 40 modules(40 drawImage calls:) ) on screen.

Below the updated code for setRenderStatesMode() to have AA functional on 2d image rendering, this is a copy/paste sample from opengl driver that works fine for opengles.


void COGLES1Driver::setRenderStates2DMode(bool alpha, bool texture, bool alphaChannel)
{
if (CurrentRenderMode != ERM_2D ...

Definitely not for 2D rendering.

- I use a irrlicht ogles version altered just a bit to allow matrix transforms on 2D(I post on forum those small changes also)
- Iphone/ipad supports anti-aliasing and also I set Antialising true when create the IrrlichtDevice
- if 2D material is not supported for ogles then I made a very bad ...

I don't have any screenshots ,I'll make few monday, but I'm sure that the antialising is the problem and think this issue is only for 2D rendering,I saw they reset many settings when switching to 2D render mode.tha

I suppose it is, m_texture renderes fine with antialising on PC with opengl.

This is the code that render the scaled image


getVideoDriver()->enableMaterial2D();
getVideoDriver()->getMaterial2D().AntiAliasing = video::EAAM_FULL_BASIC;
getVideoDriver()->getMaterial2D().TextureLayer[0].BilinearFilter = true;
matrix4 newTransform(getVideoDriver()->getTransform(ETS_WORLD ...

Hi ,

can anybody help me to make antialising work on OGLES1 branch,
I render few 2D images usoing rotation and scale and seems that the antialising doesn't work even I set the required flags. Tha


getVideoDriver()->getMaterial2D().AntiAliasing = video::EAAM_FULL_BASIC;
getVideoDriver ...

For anyone that want to easy manipulate 2D images below is a small change that should be done in the irrlicht sources and a short example of image rotation. I think it will be great to have this in the irrlicht public sources if this don't break anything else.

In setRenderStates2DMode() method ...

[ChaiRuiPeng] : it would be illogical to completely recreate irrlicht just to not include functionality for 3d because some people will only use 2d.

I never said to recreate irrlicht!
All I want is to have video driver transformations working for 2D image rendering ,I mean this code working ...

It is logical that Irrlicht use 3D to render 2D , the engine use opengl/directx calls to render images(textures),but I don't understand why I should make my work harder faking 2D using 3D ,also I'll make this fake somebody will do it again why we can't easily add this in the irrlicht engine and ...

Hi,

I saw many posts related to 2D image rotation issue with implementations of new image classes to handle rotations,but this will make things much complex when the game should be scalable, the best way to handle transformations is to have the video driver behaving as Graphics class in java ,at ...
