For basic types, the variable can be initialized by setting it equal to a literal value: Note that … See more Basic types in GLSL are the most fundamental types. Non-basic types are aggregates of these fundamental types. See more Structs are defined much like C++ (note: the C-style typedef struct *{} syntax is notsupported). GLSL does not support anonymous structures (ie: structs without a type name), and structs must have at least one member … See more Basic types can be grouped into sequences of those elements, called arrays. This generally works like in C/C++, but there are some limitations. First and foremost is that … See more Groups of variables that use the input, output, or uniform type qualifierscan be grouped into named blocks. These have special syntax, and appear similar to a struct definition. However, they are not equivalent to structs.
