C++ (Cpp) CameraPersp::getLensShift Examples

Example #1

File: CameraLensShiftTestApp.cpp Project: AKS2346/Cinder

void CameraLensShiftTestApp::setup()
{
	CameraPersp cam( getWindowWidth() * 0.5f, getWindowHeight(), 40.0f, 0.1f, 1000.0f );
	cam.setEyePoint( Vec3f(-50.0f, 0.0f, 0.0f) );
	cam.setCenterOfInterestPoint( Vec3f::zero() );

	mOverview.setCurrentCam(cam);

	// set camera to size of half the window
	mCamera = CameraPersp( getWindowWidth() * 0.5f, getWindowHeight(), 40.0f, 2.5f, 20.0f );
	mCamera.setEyePoint( Vec3f(0.0f, 0.0f, -15.0f) );
	mCamera.setCenterOfInterestPoint( Vec3f::zero() );

	//
	mFont = Font("Tahoma", 18);

	mLensShift = mCamera.getLensShift();
}

Example #2

File: CameraLensShiftTestApp.cpp Project: AKS2346/Cinder

void CameraLensShiftTestApp::update()
{
	// gradually shift to desired value
	Vec2f shift = mCamera.getLensShift();
	mCamera.setLensShift( shift + 0.1f * (mLensShift - shift) );
}
