Visualization of Black Hole Based on Computational Relativistic Fluid Dynamics

Visualization of a \ eld", which is a physically invisible concept, is a main subject of scienti c visualization. In this paper described is a method for visualizing a great gravitational eld like a black hole. We assume a velocity vector eld of imaginary uid in the vicinity of the black hole for its e ective visualization. We describe the eld by using equations so called \Eulerian method". This approach can easily display both the direction and the magnitude of ow velocity of the eld. We have succeeded in obtaining the equations of uid and visualizing the velocity vector eld of uid in the vicinity of the black hole. Experimental results e ectively show invisible phenomena including time delay caused by the great gravitation.
