ANIMATIONS of isosurfaces of R^2

Show full 4-d geometry. Animation time = Im(z2) (goes from 0 to 0.5), horizontal axes are Re, Im z1 (from 0 to 0.25) and vertical axis is Re(z2) (0 to 0.25)

alpha = 0.13 , 0.50 , 0.72 , 0.92

Rotating Im(z2)=0 slice (slices shown in figures 1 & 2 of paper)

alpha = 0.03 , 0.13 , 0.28 , 0.50 , 0.61 , 0.72 , 0.79 , 0.85 , 0.92

Rotating Re(z2)=Im(z2) slice

alpha = 0.03 , 0.13 , 0.28 , 0.50 , 0.61 , 0.72 , 0.79 , 0.85 , 0.92

Gratuitous rotating version of one of the spheres in figure 4 of paper

DOWNLOAD C program code

The tar file below may be downloaded, and provides self-contained C code (main file: K3.c) to numerically calculate the Ricci-flat Kahler potential for the one Kahler parameter family of metrics described in our paper. The code implements the algorithm described in our paper. We have placed it on the web to enable interested parties to explicitly see this method and its implementation. The code is commented to some extent, but a grasp of programming (and to some extent the C language) is necessary to fully interpret the program. If you download this code, please email us to let us know, and definitely give us feedback if you have any.
