C++ (Cpp) SetFocusPosition Examples

Example #1

File: camera.cpp Project: xyuan/VegaFEM_lib

void SphericalCamera::MoveFocusUp(double amount)
{
  double focusPos[3];
  GetFocusPosition(focusPos);
  focusPos[0] += amount * yAxis[0];
  focusPos[1] += amount * yAxis[1];
  focusPos[2] += amount * yAxis[2];
  SetFocusPosition(focusPos);
}

Example #2

File: Camera.cpp Project: artemeliy/inf4715

//////////////////////////////////////////////////////////////////////////
/// Adjust camera height.

/// @param  height          - The new height. 
//////////////////////////////////////////////////////////////////////////
void Camera::AdjustCameraHeight(VCNFloat height)
{
  const Vector3& camPos = GetViewerPosition();

  const float adjustHeight = height - oldViewerHeight;
