“…This method utilises the characteristics of a previous operational procedure for matrices and vectors, and it that uses a GPU [26] to calculate the electric field and create a discharge pattern in real time. In this present study, we generate sounds that correspond to the discharge patterns described by Matsuyama et al [8].…”

“…Thus, these cannot be employed for real-time implementations. A method for simulating spark discharges in real-time animations was published last year [8]. This method utilises the characteristics of a previous operational procedure for matrices and vectors, and it that uses a GPU [26] to calculate the electric field and create a discharge pattern in real time.…”

“…Several CG procedures have been proposed for expressing spark discharges [1][2][3][4][5][6][7][8][9]. However, few studies have proposed techniques for simulating the sound of thunder and there are currently no techniques available for the dynamic creation of effective noise that can be used in interactive content such as virtual reality.…”

A technology for automatically creating and adding sound to interactive CG animations of spark discharges in an efficient way has been developed. In the procedure proposed in this paper, the user inputs the electric charge distribution, boundary conditions and other parameters affecting the initiation of electric discharges in virtual space. The animation of the discharge is then created by generating and rendering the profile of the discharge pattern. The sound synchronized with the animation is automatically generated in an efficient way. The noises generated by spark discharges are shock waves, which exhibit complicated behavior; however, in this study, an empirical profile for a shock wave is employed to efficiently generate the acoustic waveform. Effective procedures for expressing lightning discharges and continuous discharges are also proposed. In this paper, we present the details of our technique and demonstrate its effect and efficiency by giving many experimental examples. We investigated the parameters and waveforms employed in this study to demonstrate the validity of this procedure.

We present an interactive technique for generating realistic lightning. Our method captures the main characteristics of the dielectric breakdown model, a physical model for lightning formation. Our algorithm uses a distance-based approximation to quickly compute the electric potentials of different charge types. In particular, we use a rational function in lieu of summed potentials to better produce interesting lightning patterns. We also propose to use the waypoints commonly available in many game scenes to guide lightning shapes in complex scenes. We found that our algorithm is 2 times faster than the state-of-the art method with better controls on lighting shapes, and can generate realistic lightning shapes interactively.
