点电荷在两无限大均匀电介质中的电场及电位移矢量.图像显示是VC+OpenGL-Point charge in two infinite uniform dielectric the electric field and electric displacement vector. Image display is VC+ OpenGL

Signed distance field calculator, using linear time algorithm. 4 passes are done to the image. Can be used to implement Valve s paper: "Improved Alpha-Tested Magnifi cation for Vector Textures and Special Effects" Done in C++ and SDL.

基于OpenGL现矢量场的箭标图，用颜色映射物理量的值。-OpenGL-based vector field arrows are plotting, using color mapping physical values.
