Abstract

In this paper, we propose methods for real-time visualization of 2D numerical simulation on GPU. A scalar field is visualized with a distribution map and a contour line map, and a vector field is visualized with arrows and particles. To real-time visualization of arrows, we propose the new technique having used Vertex Texture Fetch (VTF). A vector value is fetched by VTF from simulation results to the polygon prepared beforehand. The coordinates of a polygon are transformed based on it, and the arrow texture is mapped on a polygon. Thus, an arrow can be drawn on real-time.
