 Posted: Mon May 04, 2009 12:53 pm Post subject: Anaglyph rendering. |
 |
|
hey, though I should post a bit of code I did lately for anaglyph rendering.
| Code: |
void CGameEngine::drawAnaglyph()
{
vector3df oldPosition=camera->getPosition();
vector3df oldTarget=camera->getTarget();
matrix4 startMatrix=camera->getAbsoluteTransformation();
vector3df focusPoint= (camera->getTarget()-camera->getAbsolutePosition()).setLength(1) + camera->getAbsolutePosition() ;
//Left eye...
vector3df leftEye;
matrix4 leftMove;
leftMove.setTranslation( vector3df(-0.01f,0.0f,0.0f) );
leftEye=(startMatrix*leftMove).getTranslation();
//clear the depth buffer, and color
driver->beginScene( true, true, SColor(0,200,200,255) );
driver->getOverrideMaterial().Material.ColorMask=ECP_RED;
driver->getOverrideMaterial().EnableFlags=EMF_COLOR_MASK;
driver->getOverrideMaterial().EnablePasses=ESNRP_SKY_BOX+ESNRP_SOLID+ESNRP_TRANSPARENT+ESNRP_TRANSPARENT_EFFECT+ESNRP_SHADOW;
camera->setPosition( leftEye );
camera->setTarget( focusPoint );
draw(); // 'smgr->drawAll();' may go here
//Right eye...
vector3df rightEye;
matrix4 rightMove;
rightMove.setTranslation( vector3df(0.01f,0.0f,0.0f) );
rightEye=(startMatrix*rightMove).getTranslation();
//clear the depth buffer
driver->clearZBuffer();
driver->getOverrideMaterial().Material.ColorMask=ECP_GREEN+ECP_BLUE;
driver->getOverrideMaterial().EnableFlags=EMF_COLOR_MASK;
driver->getOverrideMaterial().EnablePasses=ESNRP_SKY_BOX+ESNRP_SOLID+ESNRP_TRANSPARENT+ESNRP_TRANSPARENT_EFFECT+ESNRP_SHADOW;
camera->setPosition( rightEye );
camera->setTarget( focusPoint );
draw(); // 'smgr->drawAll();' may go here
driver->endScene();
driver->getOverrideMaterial().Material.ColorMask=ECP_ALL;
driver->getOverrideMaterial().EnableFlags=0;
driver->getOverrideMaterial().EnablePasses=0;
camera->setPosition( oldPosition );
camera->setTarget( oldTarget );
} |
similar to the code by bob, here: http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=32209
but fixes a few problems, and more irrlicht friendly.
more images here

Wow, fantastic  Actually, this was the thing I wanted to try out with the override material, but I failed to find proper glasses. So I postponed it - guess I have to buy some urgently!
We should probably set up a tutorial with this code. |

hmm, you may have to use the svn or wait for 1.6. sorry I always work off the svn, I forget what is in each version.

@hybrid: Check out ebay, there you can find tons of these glasses.
@Luke: This is almost a candidate for the screenshot of the month competition. Absolutely awesome  . But is it real 3D? Normally the red and green bars around the objects should change their size with distance, shouldn't they?

yeah it is real 3d, and they do change. The red and green bars, reverse at the focus point (the difference between poping out, and looking far away), so it may not look like they change in that image.
have a look at some of the other shots here (you can see the size changing better):

True. Did I already mention that this is awesome? 
Your LUA stuff is also quite cool btw.
Was it hard to implement?

In worst case, simply change the color within the code snippet

I knew you would say that you pedantic **** 
Actually they are Red-Cyan glasses, the title is misleading. And this is Red-Cyan anaglyph rendering (RED/GREEN+BLUE):
From luke's code:
| Code: |
driver->getOverrideMaterial().Material.ColorMask=ECP_GREEN+ECP_BLUE;
|
Yes I am hustlin' for my 1 DX point per 5 glass purchased.
