Introduction to Amira

Description:

The main goal behind this assignment was to learn the basics of Amira. TGS's Amira can be a very useful tool if the user is aware of its abilities. Built around the Object Oriented Paradigm, Amira contains several objects built to view and study data within a 3D environment.

The objectives for the assignment were to create two scalar fields and one vector field. Using one scalar field create an isosurface, then use the second scalar field as input to a colormap on the isosurface. Last use the vector field to apply a surface LIC to the isosurface.
Isosurface scalar field equation
x*sin(y) + sin(z3), (with isovalue = 0.5)
Input to colormap
sin2(x)cos2(y) + cos(xz2)
Vector field equations
x = sin(x)
y = xyz
z = z2
