    • Abstract
  • Electron beam(EB) characteristics are important to weld shape which shows quality of EB welding machine.EB energy spatial distribution was built by single section energy model.3D visual simulation was realized for high speed transient EB based on OpenGL graphic library.Tracking algorithm of energy density isoline for single section was designed.Spatial appearance properties for EB were measured and analyzed with data of isoline.EB spatial model based on value of energy density was rendered by marching cubes(MC) algorithm in facet mode.Principle of picking 3D spatial point with mouse was figured out and key algorithms which relied on reconstruction surface data were described.The steps for measuring two points distance of spatial surface were explained in every particular.In a word,an evaluating method in quantity for EB characteristics was showed in the study.
