示例1: update
void AudioVisualizerApp::update()
{
// update FMOD so it can notify us of events
mFMODSystem->update();
// handle signal: if audio has ended, play next file
if(mIsAudioPlaying && signalChannelEnd)
playAudio( nextAudio( mAudioPath ) );
// reset FMOD signals
signalChannelEnd= false;
// get spectrum for left and right channels and copy it into our channels
float* pDataLeft = mChannelLeft.getData() + kBands * mOffset;
float* pDataRight = mChannelRight.getData() + kBands * mOffset;
mFMODSystem->getSpectrum( pDataLeft, kBands, 0, FMOD_DSP_FFT_WINDOW_HANNING );
mFMODSystem->getSpectrum( pDataRight, kBands, 1, FMOD_DSP_FFT_WINDOW_HANNING );
// increment texture offset
mOffset = (mOffset+1) % kHistory;
// clear the spectrum for this row to avoid old data from showing up
pDataLeft = mChannelLeft.getData() + kBands * mOffset;
pDataRight = mChannelRight.getData() + kBands * mOffset;
memset( pDataLeft, 0, kBands * sizeof(float) );
memset( pDataRight, 0, kBands * sizeof(float) );
// animate camera if mouse has not been down for more than 30 seconds
if(!mIsMouseDown && (getElapsedSeconds() - mMouseUpTime) > mMouseUpDelay)
{
float t = float( getElapsedSeconds() );
float x = 0.5f + 0.5f * math<float>::cos( t * 0.07f );
float y = 0.1f - 0.2f * math<float>::sin( t * 0.09f );
float z = 0.25f * math<float>::sin( t * 0.05f ) - 0.25f;
Vec3f eye = Vec3f(kWidth * x, kHeight * y, kHeight * z);
x = 1.0f - x;
y = -0.3f;
z = 0.6f + 0.2f * math<float>::sin( t * 0.12f );
Vec3f interest = Vec3f(kWidth * x, kHeight * y, kHeight * z);
// gradually move to eye position and center of interest
mCamera.setEyePoint( eye.lerp(0.995f, mCamera.getEyePoint()) );
mCamera.setCenterOfInterestPoint( interest.lerp(0.990f, mCamera.getCenterOfInterestPoint()) );
