The first draft
of the Technical Manual was completed.
The 3-D Window
generates a Mesh from the Volume Data and renders this (interactively).
The 2-D windows
can draw and segment regions in the each of their Image Slices.

documenation on the Window 2D and Polygon drawing. He also added a testing
The 2-D windows
now allow the user to draw a control polyline outlining the polygon to
be rasterized. We can then paste this for re-use, edit it - by stretching
control points, deleting points and inserting points. This feature is now
The 3-D window
now renders an iso-surface, created from a mesh of the segmented data.
This is a huge step from the cube which was there previously. The user
can currently rotate,pan and zoom in this window.
We demoed IRIS
to the client. He seemed happy with what we had achieved. He is interested
in seeing how the 3-D interaction progresses although he did not specify
exactly what he wanted (left it up to us).
what needs to be added to the 3-D window and how to achieve this - ie how
to intersect rays from the user's view with the data. It was finally decided
that creating a ray (manipulating OpenGL states) and intersecting
this with the Voxel Data Structure is the best method.

needs to be developed to allow the user to be able to place the 3-D crosshairs
at a particular point on the surface of the segmented data set - esentially
clicking at a point. The user should also be able to paint on the surfece
- initially just selecting a point, whose color will then change, but potentially
expanding this to a sort of 'spray painting' or polygon drawing feature.
