WebDescription. atomicMax performs an atomic comparison of data to the contents of mem, writes the maximum value into mem and returns the original contents of mem from before the comparison occured. The contents of the memory being updated by the atomic operation are guaranteed not to be modified by any other assignment or atomic memory function ... The GLSL defines a number of predefined variablesat the various shader stages. These pre-defined variables are defined with a particular set of qualifiers, as stated in the above article. If you wish to use pre-defined variables with a different qualifier, you can re-declare the variable, but the re-declaration must use … 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. They can apply to any floating-point type (vector or matrix), or any integer type. See more 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 … See more

The only possible shader that could receive iDsPerVertex within the same draw command are the FS invocations that execute for the primitives generated by this GS.
