Abstract
Abstract: Considering the earth's curvature, the spherical regular grid model is used to organize the electromagnetic field data. In order to reduce computational complexity of ITM model, the terrain reuse is proposed to improve the efficiency of the simulation. The Multithread and the terrain reuse are combined to improve the efficiency of the multi-radiation source. Considering that the traditional ray casting algorithm which takes the cube model as the bounding box cannot draw spherical regular grid data directly, a ray casting algorithm which uses the dome model as the bounding box is proposed. Experiments show that even considering the influence of terrain, the algorithm still can get high computational efficiency and satisfy the needs of electromagnetic simulation of multi-radiation source. Taking the bounding box of dome as the model, the ray casting algorithm will be applicated widely.
