Tutorials on the Shape modelling toolbox
The models shown in these tutorials illustrate features of the AAMToolbox software. They are not designed to understand the shape and appearance modelling which is better done from the published literature for example.

Three ways to use AAMToolbox
1) Analysing shapes. i.e. the arrangement of points around a shape
2) Analysing shape and appearance. In addition to the points around a shape, analyse the appearance (grey scale or colour) within the shape.
3) Analysing 3D shapes

| Tutorial on uniform growth. Consider a disc shaped canvas (tissue) in which the specified growth is uniform, isotropic and on both sides. Into what shape will the disc grow? This model is as simple as it gets. Notice that, during growth, the mesh is automatically subdivided. Notice also that the final surface is not quite flat. This is because, to allow it to deform in 3D, it is not flat initially. There are options to initialise a flat mesh and others to force it to remain flat - see options on the GUI (hover over controls to get prompts). In the absence of a polariser (there is no polariser in this example) growth will be isotropic, in other words growth in the plane of the canvas will be the average of what is specified for Kapar and Kaper (A side) and Kbpar and Kbper (B side). |
