Type Qualifier (GLSL) - OpenGL Wiki - Khronos Group

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. Contents 1 … See more 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 storage location of their data and many other … See more 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 invariantqualifier can be applied to an existing … See more There are three precision qualifiers: highp, mediump, and lowp. They have no semantic meaning or functional effect.

WebApr 17, 2024 · The GL_FRAGMENT_PRECISION_HIGH macro should only be defined when the "highp" precision modifier would be valid to use in the fragment shader (so either GLES or GLSL >= 1.30). However, some drivers (nvidia) define it even when the shader will not accept "highp", leading to shader compilation errors.
