Detailed Description

VertexFunction as in ZVTOP paper.

Function that implements:

$V(\mathbf{r})= \sum_{i=0}^N f_i(\mathbf{r})-\frac{\sum_{i=0}^N f_i^2(\mathbf{r})}{\sum_{i=0}^N f_i(\mathbf{r})}$

for the Track and InteractionPoint objects $f_i(\mathbf{r})$ given to it at construction for the Vector3 $\mathbf{r}$ specifed.
The above formula is modified thus by additional (Kip, Kalpha, JetAxis) inputs:

$V(\mathbf{r})= K_{IP}f_0(\mathbf{r})+\sum_{i=1}^N f_i(\mathbf{r})-\frac{K_{IP}f_0^2(\mathbf{r})+\sum_{i=1}^N f_i^2(\mathbf{r})}{K_{IP}f_0(\mathbf{r})+\sum_{i=1}^N f_i(\mathbf{r})}$

$K_{IP}$ is therefore just a weight on the InteractionPoint

$V(\mathbf{r})\rightarrow V(\mathbf{r})exp(-K_{\alpha}\alpha^2)$

Where $\alpha$ is the angle between JetAxis and $\mathbf{r}$ . $K_{IP}$ is then just a weight on the Jet Axis.

This class constucts GaussTube and GaussEllipsoid objects and uses thier valueAt(Vector3 Point) to perform the evaluation, how the tubes are evaluated depends on them.

Destruction cleans up all GaussTube and GaussEllipsoid objects created.
