. basic types: mpeg1/MPEG2, mpeg1 for VCD, and MPEG2 for SVCD/DVD.02. Size: The pal vcd standard is 352x288, the pal SVCD standard is 480X576, And the pal dvd standard is 720x576.03. Image aspect ratio: Generally, use the 4-3 625 line pal, which is the ratio of the TV screen.04. Recovery rate: The PAL standard is 25fps.05. Bit Rate Control: Bit Rate Control Algorithms are the key factors that cause different encoding efficiency and quality of encoder. The MPEG standard does not specify the speci
mappingdisplacement mapping displacement map that we will introduce in the next article. It is different from the previous methods, displacementmapping is a way to change the surface of an object. A technique called micropolygons (micropolygons) Tessellate (MOSAIC) is used to truly change the surface details of an object. The specific process is as follows. First, according to the screen resolution, the visible surface of the model is embedded with a
limited, and the amount of work that needs to be increased is only for the artist to save the height map to the alpha channel. Very cost-effective.
However, for technical researchers, such performance is obviously not satisfactory. Therefore, along with the idea of parallax Paster, shadermodel3.0 is used. There is an algorithm for physically changing the surface of an object. This is the displacement ing we will introduce in the next article.

The second stage, the application of color matching software
Quickly understand the above commonly used some color knowledge, you can use software to color, here I summed up a number of methods, we can do a reference, because everyone's color habits are different, only for reference.
