The color plates give you an idea of the kinds of things you can do with the OpenGL graphics system. The next several paragraphs briefly describe the order in which OpenGL performs the major graphics operations necessary to render an image on the screen. Appendix A, "Order of Operations" describes this order of operations in more detail. 颜色板给你一个想法的这样的东西，你可以做图形系统。在未来几个段落简述秩序，在这种秩序的表现主要图形操作，有必要使图像在屏幕上。附录一， "命令的行动" ，描述了这项命令的行动，更详细的描述。
1. Construct shapes from geometric primitives, thereby creating mathematical descriptions of objects. (OpenGL considers points, lines, polygons, images, and bitmaps to be primitives.) 1 。构建形状从几何原语，从而创造数学描述的对象。 （ OpenGL的考虑点，线，多边形，图像，位图，将原始） 。
2. Arrange the objects in three−dimensional space and select the desired vantage point for viewing the composed scene. 2 。安排物体在三维空间中，并选择想要的有利位置饱览组成的现场。
3. Calculate the color of all the objects. The color might be explicitly assigned by the application,
determined from specified lighting conditions, or obtained by pasting a texture onto the objects.3 。计算颜色的所有物体。颜色可能会明确指定由申请时，确定由特定的照明条件，或以粘贴纹理上的物体。
4. Convert the mathematical description of objects and their associated color information to pixels on the screen. This process is called rasterization.4 。转换的数学描述物体及其相关的颜色信息，以像素在屏幕上。这一过程被称为栅格化。
