2 . use the mew accelerate function of opengl to accelerate the units display . have adopted the three dimension graphics and opengl ' s technology , it makes use of stencil test to carry on cutting operation , which reduces complexity of programming and has raised the speed and efficiency of displaying 一2 ?根据离散元单元图可视化难点,结合目前各种国内外图形可视化加速方法特点,我们采用新大加速方法进行单元加速,利用op即gl加速结合计算机图形学原理加快单元图形显示,通过对剖切单元表面的stencil操作,减少了大量求法线操作,加快单元剖切操作,减少了编程复杂性,提高了显示速度和效率。
