Cinder Tile Render example

CinderTileRender.cpp

void yourApp::renderTiles()
{
	//the size here doesn't matter, but it will get distorted if it's not the same ratio as your window
	gl::TileRender tr( getWindowWidth()*4, getWindowHeight()*4 );
	//use the default cinder view to render from
	tr.setMatricesWindow(getWindowWidth(), getWindowHeight());
	
	while( tr.nextTile() ) {
		draw();
	}
	writeImage( getHomeDirectory() + "appFolder" + getPathSeparator() +  "output.png", tr.getSurface() );
	
	//reset window matrix back to normal (if you aren't changing it with a camera)
	gl::setMatricesWindow( getWindowWidth(), getWindowHeight(), true );
}
