抄録

By numerically calculating the light ray trajectories curved by the black hole's strong gravity,
we can obtain three dimensional computer graphics images under a black hole spacetime.
In the author's previous research, the rasterization method relativistically extended has achieved high-speed rendering of them.
However, the tessellation is inefficient because of using the geometry shader in GPU.
In this paper, we solve this problem using two-step tessellation using object and mesh shaders.
In addition, the previous research renders only the objects not moving while, in this paper, we can render the objects moving in near-light speed by improving the 3D texture used for projection mapping.
These two improvements enable us to develop a chase video game on a tablet computer that renders CG in real time in a black hole spacetime.
