    camera->setTarget( oldTarget );

}
similar to the code by bob, here: http://irrlicht.sourceforge.net/phpBB2/ ... hp?t=32209

but fixes a few problems, and more irrlicht friendly.

using a secondary camera for anaglyph rendering

Post by msxfan »

In my mac osx 10.6 + irrlicht 1.6 installation this code (as well as the code posted by Bob) does not allow me to change the location and the orientation of the FPS camera. My 'solution' is to add an additional 'anaglyph' camera that is disabled by default. This secondary camera is only used for rendering without altering the primary camera settings.

Here is the header file (anaglyph.h):

Code: Select all

#ifndef _ANAGLYPH_IRRLICHT_H_
#define _ANAGLYPH_IRRLICHT_H_

#include <irrlicht.h>
using namespace irr;

scene::ICameraSceneNode* CreateAnaglyphCamera (scene::ISceneManager* smgr ,
											   scene::ICameraSceneNode* pPlayerCamera);

void RenderSceneAnaglyphMac (scene::ICameraSceneNode* pAnaglyphCamera, video::IVideoDriver* driver, scene::ISceneManager* smgr , video::SColor backgroundColor,  float eyeDist = 0.01, bool endScene= true);

#endif
and the c++ source code file (anaglyph.cpp):

Code: Select all

 #include "anaglyph.h"
#include <Irrlicht/os.h>

scene::ICameraSceneNode* CreateAnaglyphCamera (scene::ISceneManager* smgr ,
											   scene::ICameraSceneNode* pPlayerCamera)
{
	scene::ICameraSceneNode* pAnaglyphCamera;
	
	pAnaglyphCamera = smgr->addCameraSceneNode();
	pAnaglyphCamera->setInputReceiverEnabled(false); 
	pAnaglyphCamera->setScale( pPlayerCamera->getScale());
	pAnaglyphCamera->setNearValue( pPlayerCamera->getNearValue());
	pAnaglyphCamera->setFarValue( pPlayerCamera->getFarValue());
	pAnaglyphCamera->setAspectRatio( pPlayerCamera->getAspectRatio());
	
	return pAnaglyphCamera;
}

void RenderSceneAnaglyphMac (scene::ICameraSceneNode* pAnaglyphCamera  , video::IVideoDriver* driver, scene::ISceneManager* smgr, video::SColor backgroundColor,	 float eyeDist,  bool endScene)
{
	scene::ICameraSceneNode* pCamera = smgr->getActiveCamera();
	
	// explicitly update attached camera animators
	pCamera->OnAnimate(os::Timer::getTime());
	pCamera->OnRegisterSceneNode();
	core::matrix4 startMatrix=pCamera->getAbsoluteTransformation(); 
	core:: vector3df focusPoint= 
	(pCamera->getTarget()-pCamera->getAbsolutePosition()).setLength(1) + pCamera->getAbsolutePosition() ; 
	
	//Left eye... 
	core::vector3df leftEye; 
	core::matrix4 leftMove; 
	leftMove.setTranslation( core::vector3df(-eyeDist,0.0f,0.0f) ); 
	leftEye=(startMatrix*leftMove).getTranslation(); 
	
	//Right eye... 
	core::vector3df rightEye; 
	core::matrix4 rightMove; 
	rightMove.setTranslation( core::vector3df(eyeDist,0.0f,0.0f) ); 
	rightEye=(startMatrix*rightMove).getTranslation(); 
	
	
	// enable secondary camera for anaglyph rendering 
	smgr->setActiveCamera(pAnaglyphCamera);
	
	// -------  RENDER LEFT EYE ----------
	driver->beginScene( true, true, backgroundColor ); 
	driver->getOverrideMaterial().Material.ColorMask= video::ECP_RED; 
	driver->getOverrideMaterial().EnableFlags=	video::EMF_COLOR_MASK; 
	driver->getOverrideMaterial().EnablePasses= scene::ESNRP_SKY_BOX+ scene::ESNRP_SOLID + 
	scene::ESNRP_TRANSPARENT+ scene::ESNRP_TRANSPARENT_EFFECT+ scene::ESNRP_SHADOW; 
	pAnaglyphCamera->setTarget( focusPoint ); 
	pAnaglyphCamera->setPosition( leftEye ); 
	pAnaglyphCamera->OnRegisterSceneNode();
	
	smgr->drawAll(); 
	
	// -------  RENDER RIGHT EYE ----------	
	driver->clearZBuffer(); 
	driver->getOverrideMaterial().Material.ColorMask= video::ECP_GREEN + video::ECP_BLUE; 
	driver->getOverrideMaterial().EnableFlags= video::EMF_COLOR_MASK; 
	driver->getOverrideMaterial().EnablePasses= scene::ESNRP_SKY_BOX+ scene::ESNRP_SOLID+ 
	scene::ESNRP_TRANSPARENT+ scene::ESNRP_TRANSPARENT_EFFECT+ scene::ESNRP_SHADOW; 
	pAnaglyphCamera->setTarget( focusPoint ); 
	pAnaglyphCamera->setPosition( rightEye ); 
	pAnaglyphCamera->OnRegisterSceneNode();	
  
	smgr->drawAll();
	
	driver->getOverrideMaterial().Material.ColorMask= video::ECP_ALL; 
	driver->getOverrideMaterial().EnableFlags=0; 
	driver->getOverrideMaterial().EnablePasses=0; 
	
	if (endScene) driver->endScene(); 
	
	// restore active camera 
	smgr->setActiveCamera(pCamera);
} 
Usage:

(1) Setup before the rendering loop:

Code: Select all

scene::ICameraSceneNode* pAnaglyphCamera =CreateAnaglyphCamera( smgr, pFpsCamera );
smgr->setActiveCamera(pFpsCamera);
where pFpsCamera is a pointer to the main camera (usually the player camera in a FPS game).

(2) Rendering loop must call:

Code: Select all

RenderSceneAnaglyphMac ( pAnaglyphCamera, driver, smgr ); 

instead of the 'traditional' code:

Code: Select all

driver->beginScene(true, true, video::SColor(255,200,200,200)); 
smgr->drawAll(); 
driver->endScene(); 
Hope this helps!

your code is segfaulting , bobs is sortof working. perhaps someone knows how to fix this demo. it includes both versions as a define.

3D in 3D? lol

meh most people don't own a microphone let alone 3D glasses. but still pretty cool even though it's useless to me outside of educational.

the link dosn'nt work

the mac code is

Code: Select all

scene::ICameraSceneNode* pAnaglyphCamera, video::IVideoDriver* driver, scene::ISceneManager* smgr , video::SColor backgroundColor,  float eyeDist = 0.01, bool endScene= true
so you need bacjgroung color, eyedist and endscene (i try this on pc : os::Timer::getTime() error , erase this fix the problem)?

and the first code crash on my pc

so, this only work with irrlicht 1.4, it is out of date. i propose a version (based on the original version by the author of this post) that work with irrlicht 1.6 and 1.7, it is terrain rendering exemple, but the caùera is buggy, i try to fix the problem.analygriph work , but not the fps camera, :(- maybe with a modified fps camera, or a big research in the doc and internet.others code don't work.but, finaly , i don't need a fps camera for my application, so, this code work, and i want to said a VERY BIG THANK to the author

Code: Select all

/** Example 012 Terrain Rendering

This tutorial will briefly show how to use the terrain renderer of Irrlicht. It
will also show the terrain renderer triangle selector to be able to do
collision detection with terrain.

Note that the Terrain Renderer in Irrlicht is based on Spintz'
GeoMipMapSceneNode, lots of thanks go to him. DeusXL provided a new elegant
simple solution for building larger area on small heightmaps -> terrain
smoothing.

In the beginning there is nothing special. We include the needed header files
and create an event listener to listen if the user presses a key: The 'W' key
switches to wireframe mode, the 'P' key to pointcloud mode, and the 'D' key
toggles between solid and detail mapped material.

Hi
I look at your code and I try to do something similar
I try somes things but I'm always stuck wioth the fps not moving,
if the main camera (in your program its pcamera) is not draw, the software seems to not move, maybe the receiver not sending the information?

did you succeed with that (its just that I try your code and its seems to be the same problem)

I'm nooby with triliant (and maybe in c++ ) and your help can be very valuable

tank you

did the code working, for me the window is freeze

the winProc need to be the win32 version (I work on windows)
how to create that

I use a standard winProc for the moment but we need the processing of the win32 but I dont know how to use it because CIrrDeviceWin32 is not in irr, I dont know how to use that kind of object

maybe I'm noob

const c8* ClassName = "CIrrDeviceWin32";

HINSTANCE hInstance = (HINSTANCE)GetModuleHandle(NULL);

MSG msg; // Message Structure
WNDCLASS wc; // Window Class structure
HWND hWnd1,hWnd2; // Window handle of main window


// Register Window style
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = NULL;
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = hBlueBrush; // Use blue brush for background
wc.lpszMenuName = NULL;
wc.lpszClassName = ClassName;


if(RegisterClass(&wc) == 0)
return FALSE;

// Create the main application window
hWnd1 = CreateWindow(
//lpszAppName,
ClassName,
lpszAppName,
WS_OVERLAPPEDWINDOW,
100, 100, // Size and dimensions of window
250, 250,
NULL,
NULL,
hInstance,
NULL);

// If window was not created, quit
if(hWnd1 == NULL)
return FALSE;


// Display the window
ShowWindow(hWnd1,SW_SHOW);
UpdateWindow(hWnd1);

Really great job!

I used your code, but I am with an issue that I cant figure it out.
The "anaglyph" only appers when I fastly move my Camera.
Any idea on this subject?

Thanks in advance,

did u succed on a dual screen or only the anaglyph with a simple device?

-----------------------------------------------------------------------------------

I have some issues all the time, I try to create window with irrlitch winproc fct but...

I try :

Code: Select all

wc.lpfnWndProc          = (WNDPROC)(irr::CIrrDeviceWin32::WndProc);
My error

Code: Select all

so I duplicate the wndProc, I change somes things but I have somethings that I ... I dont know what to do

Code: Select all

driver->setViewPort(rect<s32>(0,0,ResX,ResY));		driver->beginScene(true,true,SColor(255,100,100,100),hWnd1);				smgr->setActiveCamera(camera[0]);	
		smgr->drawAll();
		driver->endScene();
				driver->beginScene(true,true,SColor(255,100,100,100),hWnd1);				
		smgr->setActiveCamera(camera[2]);				
		smgr->drawAll();
		driver->endScene();
we have here 2 camera,
[0] is a fps cam
[2] is a modification of the cam

but that make each cam show each time, like in stereo but its not.
how stop using the drawAll(), because now I need it for the movement of the camera[0].
can I edit the code of drawAll(), its on ISceneManager.h, but I dont have .cpp

any Idea?

Re: Anaglyph rendering.

Post by Guillaum »

Hi,

I'm currently trying to make Anaglyph Rendering work with Irrlicht 1.8.

I didn't manage to make it work properly yet, but i'd like to share a first correction to the source code proposed by Luke:
Luke wrote:hey, though I should post a bit of code I did lately for anaglyph rendering.

Code: Select all

void CGameEngine::drawAnaglyph()
{
    vector3df oldPosition=camera->getPosition();
    vector3df oldTarget=camera->getTarget();
    
    matrix4 startMatrix=camera->getAbsoluteTransformation();
 
        [......]
 
 
The following call :

Code: Select all

 camera->updateAbsolutePosition();
must be added before calling:

Code: Select all

matrix4 startMatrix=camera->getAbsoluteTransformation();
Then, the code snippets should be corrected:
http://irrlicht3d.org/wiki/index.php?n= ... hRendering

Final code:

Code: Select all

void CGameEngine::drawAnaglyph()
{
    vector3df oldPosition=camera->getPosition();
    vector3df oldTarget=camera->getTarget();
 
    camera->updateAbsolutePosition();   
    matrix4 startMatrix=camera->getAbsoluteTransformation();
 
        [......]
