hi,
I would like to modify the camera settings of a SimpleSceneManager (SSM)
object, in this way:
MultiDisplayWindowPtr MDWndPtr = MultiDisplayWindow::create();* // a
multi display window is involved*
/* initialize multi display window
......
*/
g_SceneManager = new SimpleSceneManager;
g_SceneManager->setWindow(MDWndPtr);
g_SceneManager->setRoot(g_SceneRoot);
g_SceneManager->showAll();
PerspectiveCameraPtr ptrCam = g_SceneManager->getCamera();
beginEditCP(ptrCam);
ptrCam->setFov(deg2rad(90));
endEditCP(ptrCam);
* g_SceneManager->setCamera(ptrCam);* // this line will cause a
corruption of the heap
*// change initial LookAt parameters*
Pnt3f from = g_SceneManager->getNavigator()->getFrom();
from[0] = from[1] = 0;
from[2] = 3;
g_SceneManager->getNavigator()->setFrom(from);
from[0] = from[1] = from[2] = 0;
g_SceneManager->getNavigator()->setAt(from);
MDWndPtr->init(); *// program crashed here*
