abstract     : We present an adaptive animation method for electrical
discharges. Electric discharges can be simulated
using the dielectric breakdown model. Regular
discretization of the governing Laplace equation
leads to huge equation systems, and the computational
cost of solving the equations quickly becomes
prohibitive at high resolutions, especially
for simulations in 3D. In contrast, our method discretizes
the Laplace equation on an adaptive octree,
reducing the size of the problem significantly, and
making simulations of high resolution 3D datasets
and even 3D animations feasible.
In order to enhance realism for lightning animations,
we propose a particle simulation that animates
the residual positive charge. Thus, interaction
of electrical discharges with their surroundings
can be simulated.
