## 10 Jul Kavita Bala describes Cornell’s pioneering computer graphics research

A major quest in computer graphics research has been to understand and virtually model the appearance of the real world. In this lecture—the last in the summer lecture series sponsored by the School of Continuing Education and Summer Sessions—computer science professor Kavita Bala talks about the university’s pioneering research in this area in her talk “Virtual Realism and Computer Graphics” on July 29 in Call Auditorium, Kennedy Hall.

My curves.

For electronic drawing
Mathematica code 1.

Plot[Piecewise[{{((0.5 – x)/
0.5) (x/2) + (x/0.5) (0.25 + (x – 0.5) 1.1),
x <= 0.5}, {((0.25 – Mod[x, 0.25])/0.25) (0.25 + (x – 0.5) 1.1) +
Mod[x, 0.25]/0.25 (0.525 + (x – 0.75) 1.25),
x > 0.5 && x <= 0.75}, {0.525 + (x – 0.75) 1.25, x > 0.75}}] , {x,
0, 1}]

Hopefully for in 3d one face of a tetrahedron but curved.
Mathematica code 2.

Manipulate[
ListPlot[Table[
If[t > d, {0,
0}, {(e + 1 – c (t/d)) Cos[t], (e + 1 – c (t/d)) Sin[t]}], {t, 0,
2 Pi, 0.0011}],
AspectRatio -> Automatic,
PlotRange -> {{-(e + 1), (e + 1)}, {0, (e + 1)}} ,
PlotTheme -> "Minimal"], {c, 0, e + 1}, {d, 0.0011, Pi}, {e, 0, 4}]
