OSG结合GLSL，在一个立方体上贴纹理后，对其进行颜色校正，更改为已存在的查找表的颜色值，GLSL可以对纹理颜色值进行更改-OSG integration GLSL, posted in a cube texture is carried out after color correction, change the existing look-up table of color values, GLSL texture color values can be changed

针对摸个引用，能够分离有限元模型的表面。-It can be useful to separate the surface of a finite element model for certain applications such as fatigue analysis. For example, if cracks are known to initiate on the material surface, then the inclusion of sub-surface element
