, we can use glcolor4f () instead of glcolor3f (). Most people think of Alpha as how opaque a material is. An Alpha value of 0.0 wocould mean that he material is completely transparent. A value of 1.0 wocould be totally opaque. The blending equation: (RS Sr + rd dr, gs sg + gd dg, BS Sb + bd dB, as SA + AD da) OpenGL will calculate the result of Blending two pixels based on the above equation. the S and subscripts specify the Source and Destination pixels. the S and D components are the blend fa

method. The size of the code unit is equivalent to the number of bits in a particular encoding:UTF-8: The code unit in the UTF-8 consists of 8 bits, and in UTF-8, each code point is often mapped to multiple code units because of the small size of the code unit. Code points are mapped to one, two, three, or four code units;The code unit in utf-16:utf-16 consists of 16 bits, and the UTF-16 code unit size is twice times the 8-bit code unit. Therefore, a code point with a scalar value less than u+1
