WebDec 14, 2010 · All methods of vertex compression that are trivially implementable on GPU involve taking the floating-point source data and storing it in a value with less bits of precision; usually the value is either an integer or a fixed-point with a limited range (typically [-1; 1] or [0; 1]). This process is known as quantization. WebThus in general if you shift a number to left by n bits, it gets multiplied n times by 2. The Bitwise right shift operator The right shift operator shifts the bits towards the right. This means it does the exact opposite of the left shift operator i.e. every time we shift a number towards the right by 1 bit it divides that number by 2.
