closestPlanePointIndex

private float closestPlanePointIndex(javax.vecmath.Point3f kStart,
 int[] aiIndex)

For the plane, all vertices have z-value set to zero. Because the mesh is closed, even for the plane, the edge triangles wrap around the back of the mesh, and are co-planar with the forward-facing triangles (the ones that display the data) -- when picking is done, the pickClosest sometimes returns the back-facing triangle. This function returns the correct, visible triangle for the plane:

Parameters:

kStart - DOCUMENT ME!

aiIndex - DOCUMENT ME!

Returns:

DOCUMENT ME!

drawPoint

private void drawPoint(javax.vecmath.Point3f kStart,
 int[] aiIndex,

Draw the user-selected point as a sphere on the triangle mesh:

Parameters:

kStart - DOCUMENT ME!

aiIndex - DOCUMENT ME!

iWhich - DOCUMENT ME!

drawTriangle

private void drawTriangle(javax.vecmath.Point3f kStart,
 int[] aiIndex,
 int iWhich)

Draw the user-selected triangle as a black triangle, save the original color so it can be restored:

Parameters:

kStart - DOCUMENT ME!

aiIndex - DOCUMENT ME!

iWhich - DOCUMENT ME!

restoreTriColor

private void restoreTriColor()

Resets the previously picked triangle to it's orginal color:

setColorsLUT

private void setColorsLUT()

Update the colormap based on the LUT:

setupLight

private void setupLight()

Sets up a direction lightsource for the scene.
