iPhone problem with camera orientation

[elkree]

Hi, i'm porting a soccer game from linux to iPhone and i have some problems

with this code

Code: Select all

	Ogre::SceneNode* cameraNode = gameSceneMgr->getSceneNode("basicNode")->createChildSceneNode("cameraNode");
	camera = gameSceneMgr->createCamera("gameCamera");
	cameraNode->setPosition(Ogre::Vector3(0, GameStates::SIZEY/2, -GameStates::SIZEX*1.2));
	cameraNode->attachObject(camera);

	camera->lookAt(Ogre::Vector3(0, 0, 50));
	camera->setNearClipDistance(1);
	camera->setAspectRatio(Ogre::Real(OgreFramework::getSingletonPtr()->m_pViewport->getActualWidth()) / 
							  Ogre::Real(OgreFramework::getSingletonPtr()->m_pViewport->getActualHeight()));
	OgreFramework::getSingletonPtr()->m_pViewport->setCamera(camera);

using in iphone
*-*-* OGRE Initialising
*-*-* Version 1.7.3 (Cthugha)
Installing plugin: OpenGL ES 1.x RenderSystem

and in linux normal with openGL render system and ogre version 1.7.3

the results are:

using linux


using iphone

main problem is the orientation of the camera, set position works fine with the players, the soccer map i think i can't visualize correctly because with openglES1 i can't put a texture in a plane, using ogre 1.8 with opengles 2 can correct this? and the gorilla GUI can be corrected turning 270 degree

any idea about how to resolve the camera problem? i tried to use set direction/set orientation/look at methods and i don't have any correct result

i created the viewport with the next lines before making the camera:

Code: Select all

	m_pViewport = m_pRenderWnd->addViewport(0);
	m_pViewport->setBackgroundColour(ColourValue(0.8, 0.8, 0.8, 1.0));

	m_pViewport->setCamera(0);

thx!

playing with set direction in camera class

from api:
void Ogre::Camera::setDirection ( const Vector3 & vec )
Sets the camera's direction vector.

using the next core

Code: Select all

    OgreFramework::getSingletonPtr()->m_pLog->logMessage("SceneGame :: camara debug: "+Ogre::StringConverter::toString(camera->getDirection()));
	camera->setDirection(0,-1,0);
    OgreFramework::getSingletonPtr()->m_pLog->logMessage("SceneGame :: camara debug2: "+Ogre::StringConverter::toString(camera->getDirection()));

the result:

SceneGame :: camara debug: 0 0 -1
SceneGame :: camara debug2: 0 -0.5 -0.5

this result isn't the expected reading the api, can be a bug? how i can put a correct direction?

thx

my solution at this problem is: move the world, not the camera

Another option would be to set the viewport orientation according to how the device is oriented.

The main problem is the iphone simulator provided by apple, deploying the project in a normal device (iphone or ipad) looks really good!
