C++ (Cpp) sceneCenter Examples

Example #1

File: Base3DView.cpp Project: kkaushalp/aphid

void Base3DView::frameAll()
{
    Vector3F coi = sceneCenter();
    Vector3F eye = coi + Vector3F(0.f, 0.f, 100.f);
    
    getCamera()->lookFromTo(eye, coi);
}

Example #2

File: TrackballViewer.cpp Project: xiaojhl/Image-2-Shape

void TrackballViewer::resetCamera()
{
  // assume only one dispObjects MainCanvas exist here
  Bound* scene_bounds = dynamic_cast<TrackballCanvas*>(dispObjects[0])->getBoundBox();

    (scene_bounds->minY + scene_bounds->maxY) / 2,
    (scene_bounds->minZ + scene_bounds->maxZ) / 2);

  setSceneCenter(scene_center);

  float x_span = (scene_bounds->maxX - scene_bounds->minX) / 2;
  float y_span = (scene_bounds->maxY - scene_bounds->minY) / 2;
  float z_span = (scene_bounds->maxZ - scene_bounds->minZ) / 2;
  float scene_radius = x_span>y_span ? (x_span > z_span ? x_span : z_span) : (y_span > z_span ? y_span : z_span);
  scene_radius *= 1.5;

  setSceneRadius(scene_radius);
  camera()->fitSphere(scene_center, scene_radius);



  setStateFileName(QString((dynamic_cast<TrackballCanvas*>(dispObjects[0])->getFilePath()+"/camera_info.xml").c_str()));
  if (restoreStateFromFile())
    std::cout << "Load camera info successes...\n";
  else

  // set the scene in MainCanvasViewer
  syncCamera();
  main_canvas_viewer->setSceneCenter(sceneCenter());
  main_canvas_viewer->setSceneRadius(sceneRadius());
  main_canvas_viewer->camera()->setZClippingCoefficient(camera()->zClippingCoefficient());
}
