These qualifiers change particular aspects of the variable, such as where they get their data from and so forth. They come in a number of different categories. Ver mais There are a large number of layout qualifiers which can be applied to a variety of defined constructs, from interface blocksto shader stage inputs and outputs. These affect the … Ver mais image variables, shader storage blocks, and the variables within a shader storage block can have a number of memory qualifiers applied to them. These affect how they can be used and how values read from/written to … Ver mais There are three precision qualifiers: highp, mediump, and lowp. They have no semantic meaning or functional effect. They can apply to any floating-point type (vector or matrix), or … Ver mais There is a way to qualify certain output variables as being invariant. This allows different programs to compute the exact same answer, assuming certain conditions are met. The … Ver mais
