A type qualifier is used in the OpenGL Shading Language (GLSL) to modify the storage or behavior of global and locally defined variables. 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.
