法线

The plastic strain component along the normal of loading path is presented to measure the hardening.

其中，材料强化程度采用沿路径法线方向的塑性应变分量描述。

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.

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OpenGL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。

Support for all modern per-pixel lighting and rendering techniques including normal mapped, parameterized Phong lighting; virtual displacement mapping; light attenuation functions; pre-computed shadow masks; and pre-computed bump-granularity self-shadowing using spherical harmonic maps.

引擎本身还能支持现所有的像素光照和像素渲染技术，包括：法线贴图，参数化的Phong光照设置功能；位移贴图；灯光的衰减控制功能；预计算的阴影模板；使用了球形环境映射贴图所产生出的凹凸贴图效果。

Support for all modern per-pixel lighting and rendering techniques including normal mapped, parameterized Phong lighting; custom artist controlled per material lighting models including anisotropic effects; virtual displacement mapping; light attenuation functions; pre-computed shadow masks; directional light maps; and pre-computed bump-granularity self-shadowing using spherical harmonic maps.

支持现今所有的像素级光渲染技术比如法线贴图，参数级光照，艺术家自定义的材质光模型分属性管理，包含了各向异性过滤，虚拟置换贴图，光衰减功能，预计算的光影蒙版，指向性光影贴图和预计算的使用球型协调贴图技术的颗粒状自我阴影。

Directional Light Mapping enables the static shadowing and diffuse normal-mapped lighting of an unlimited number of lights to be precomputed and stored into a single set of texture maps, enabling very large light counts in high-performance scenes.

定向光贴图技术提供给静态光影和和扩散法线贴图光照几乎无限的灯光数量以作为预渲染或者是存储在一个单独的贴图套件中，在高精度效果场景中提供大量的灯光效果。

This function recomputes the normals.

这个函数重新计算了法线。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。

In slot 2 in your bag put wrapping paper, quantity does not matter in this case.

在你的书包里槽2把包装纸、数量无关紧要。
