Dynamic Demonstration of Ceramic Grain Growth in Three Dimensions

摘要

Microstructural evolutions of ceramic grain growth were dynamically demonstrated withrn3D graphical display techniques. Based on the principles of grain growth in ceramics, the data ofrncoordination in different atoms were calculated with Monte-Carlo method at atomistic scale.rnRealistic images in three-dimension were displayed onto two-dimension monitor by projection,rnillumination and atomization, using Visual C++ and OpenGL languages. Different small spheresrnwere used to model different kind of atoms, which filled within a cubic space. The radius andrncoordination for different atoms were then determined according to corresponding ratios by using ofrnperspective projection of OpenGL languages. The applications of illuminating, texturizing andrnatomization techniques enhanced greatly the stereo effect of images simulated.
