Transition Slides in Beamer

Imagine that you want to produce a series of three transition or thematically linked slides. By that, I mean that most of the information on the slide remains the same, with minor additions, deletions or changes.

As an example consider the following three frames:

The first step, in this case, would be to draw the three figures in a drawing program (like Inkscape), preferably one which supports layers.

I like to draw a border around the image. That way, when I export the image into PNG or PDF format the dimensions of the image are conserved.

Next, we use the following self-explanatory TeX code:

	\begin{frame}
	%\frametitle<1>{Title for slide 1}
	%\frametitle<2>{Title for slide 2}
	%\frametitle<3>{Title for slide 3}
	\frametitle{MSD}
	\begin{overprint}
	\onslide<1> Trajectory of a single particle, $\mathbf{r}(t)$
	\onslide<2> Take snapshots at fixed time intervals $\Delta t$
	\onslide<3> Report discretized trajectory, $\{\mathbf{r}_1, \mathbf{r}_2, ..., \mathbf{r}_N\}$, where
	$$\mathbf{r}_i = \mathbf{r}(t = (i-1) \Delta t).$$
	\end{overprint}
	\bigskip
	\begin{overprint}
	\onslide<1>\centerline{\includegraphics[scale=0.4]{figs/msdtut1a.png}}%
	\onslide<2>\centerline{\includegraphics[scale=0.4]{figs/msdtut1b.png}}%
	\onslide<3>\centerline{\includegraphics[scale=0.4]{figs/msdtut1c.png}}%
	\end{overprint}
	\end{frame}
