Hi,
Hi,
I am new to Android programming. I followed the osgAndroidExampleGLES1 and
developed a small example. It is working well but have a small issue.
First of all I will give my complete code here
Code:
#include"osgModel.hpp"
OsgMainApp osgM;
void OsgMainApp::readModel()
{
loadedModel = osgDB::readNodeFile("/mnt/sdcard/OSG/Piller.osg");
if (loadedModel == 0)
{
LOG("Model not loaded");
}
else
{
LOG("Model loaded");
loadedModel->setName("/mnt/sdcard/OSG/Piller.osg");
}
}
void OsgMainApp::initOsgWindow(int sW,int sH)
{
x=0;
y=0;
width=sW;
height=sH;
_viewer = new osgViewer::Viewer();
_viewer->setUpViewerAsEmbeddedInWindow(x, y, width, height);
_root = new osg::Group();
_viewer->realize();
_state = _root->getOrCreateStateSet();
_state->setMode(GL_LIGHTING, osg::StateAttribute::ON);
_state->setMode(GL_DEPTH_TEST, osg::StateAttribute::ON);
_state->setMode(GL_CULL_FACE, osg::StateAttribute::ON);
_viewer->addEventHandler(new osgViewer::StatsHandler);
_viewer->addEventHandler(new
osgGA::StateSetManipulator(_viewer->getCamera()->getOrCreateStateSet()));
_viewer->addEventHandler(new osgViewer::ThreadingHandler);
_viewer->addEventHandler(new osgViewer::LODScaleHandler);
_manipulator = new osgGA::KeySwitchMatrixManipulator;
_manipulator->addMatrixManipulator( '1', "Trackball", new
osgGA::TrackballManipulator() );
_manipulator->addMatrixManipulator( '2', "Flight", new
osgGA::FlightManipulator() );
_manipulator->addMatrixManipulator( '3', "Drive", new
osgGA::DriveManipulator() );
_manipulator->addMatrixManipulator( '4', "Terrain", new
osgGA::TerrainManipulator() );
_manipulator->addMatrixManipulator( '5', "Orbit", new
osgGA::OrbitManipulator() );
_manipulator->addMatrixManipulator( '6', "FirstPerson", new
osgGA::FirstPersonManipulator() );
_manipulator->addMatrixManipulator( '7', "Spherical", new
osgGA::SphericalManipulator() );
_viewer->setCameraManipulator( _manipulator.get() );
_viewer->getViewerStats()->collectStats("scene", true);
_viewer->getCamera()->setViewport(0,0,sW, sH);
_viewer->getCamera()->setClearMask(GL_DEPTH_BUFFER_BIT );
modelSwitch=new osg::Switch;
trans=new osg::MatrixTransform();
trans->addChild(loadedModel.get());
modelSwitch->addChild(trans.get());
_root->addChild(modelSwitch.get());
_viewer->setSceneData(NULL);
_viewer->setSceneData(_root.get());
_manipulator->getNode();
_viewer->home();
_viewer->getDatabasePager()->clear();
_viewer->getDatabasePager()->registerPagedLODs(_root.get());
_viewer->getDatabasePager()->setUpThreads(3, 1);
_viewer->getDatabasePager()->setTargetMaximumNumberOfPageLOD(2);
_viewer->getDatabasePager()->setUnrefImageDataAfterApplyPolicy(true,
true);
}
void OsgMainApp::renderOsg(osg::Matrix mat)
{
modelSwitch->setAllChildrenOff();
modelSwitch->setChildValue(trans,1);
osg::Vec3f tr,scal;
osg::Quat rot,so,rot1,rot2;
mat.decompose(tr,rot,scal,so);
rot1=rot;
rot2=rot;
rot.makeRotate(osg::DegreesToRadians(45.0),1,0,0);
rot2.makeRotate(osg::DegreesToRadians(180.0),0,1,0);
trans->preMult(osg::Matrix::rotate(rot1));
trans->preMult(osg::Matrix::rotate(rot));
trans->preMult(osg::Matrix::rotate(rot2));
//trans->preMult(osg::Matrix::scale(osg::Vec3(0.5,0.5,0.5)));
_viewer->frame();
}
JNIEXPORT void JNICALL
Java_com_Samples_initApplicationNative(
JNIEnv* env, jobject obj, jint width, jint height)
{
screenWidth = width;
screenHeight = height;
osgM.initOsgWindow(screenWidth,screenHeight);
osgM.readModel();
}
JNIEXPORT void JNICALL
Java_com_Samples_renderer(
JNIEnv* env, jobject obj, jint width, jint height)
{
//osgM.initOsgWindow(screenWidth,screenHeight); //ERROR IS WITH THIS
osg::Matrix mat;
mat=osg::Matrix::scale(osg::Vec3(1.5,1.5,1.5));
osgM.renderOsg(mat);
}
In this code I called initOsgWindow and readModel in
"Java_com_Samples_initApplicationNative".
In "Java_com_Samples_renderer" function I am calling "renderOsg". If I call
only this function then the
model is not appearing on the screen. If I call "initosgWindow" also then the
model appears on the
screen. But my model has some animation so the animation is playing incorrect
as the osg is setting
every time.
I have gone through the "osgAndroidExampleGLES1" several times. But I am not
able to figure out the error?
What could be the mistake to reset the osg settings every time?
...
Thank you!
Cheers,
Koduri
