WebSwizzling — beyond being a great name — is a nice feature in GLSL for accessing the properties of a vector. You can get a single float from a vector using .r, .g, .b or .a.For example: Under GLSL version 3.30, Sampler arrays (the only opaque type 3.30 provides) can be declared, but they can only be accessed by compile-time integral Constant Expressions. So you cannot loop over an array of samplers, no matter what the array initializer, offset and comparison expressions are. Visualizza altro Basic types in GLSL are the most fundamental types. Non-basic types are aggregates of these fundamental types. Visualizza altro 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), … Visualizza altro Basic types can be grouped into sequences of those elements, called arrays. This generally works like in C/C++, but there are … Visualizza altro Variables of almost any type can be initialized with an initial value. The exceptions are: 1.
